Can a hydrogen fuel cell car be affordable? Is it safe? Experts tell you the answer.

  CCTV News:In the development process of hydrogen energy industry, reducing cost and ensuring safety are two core concerns. In the face of this emerging industry, how to answer the public’s concerns? Let’s take a look at the answers given by the guests in the "On Tao" column.

  Reduce industrial costs

  Dong Yang, First Vice President of the World Automobile Organization and former Executive Vice President of China Automobile Industry Association:It is still more expensive than this gasoline car, even more expensive than the ordinary battery car. However, I will tell you that there is such a rule in automobile production. After you reach this scale of hundreds of thousands and millions, its cost will drop to one tenth of the original. Or this aircraft engine is the price of gold, and the car engine, with the same technology, is the price of cast iron.

  Zhang Weidong, Director of Energy and Environment Project of the United Nations Development Programme:According to some experts, the cost of battery stack is 11,833 yuan per kilowatt now, and it will reach 668 yuan by 2025, which will be lower.

  Dong Yang:Compared with the internal combustion engine, the fuel cell stack is basically a quasi-static or quasi-dynamic process, and many processes are very similar, but there is no reason to say that the stack must be more expensive than the internal combustion engine. Now it is only a matter of technical maturity and market capacity.

  Zhang Xiaoqiang, Executive Vice President and Executive Director of China International Economic Exchange Center.To solve the cost problem of hydrogen production, if we don’t have a reasonable framework in terms of electricity price and so on, it may trouble enterprises for a long time, that is, the cost can’t be reduced. How can we have a reasonable electricity price system? For example, when using off-peak electricity, can we make it cheaper enough, so that large users can establish such a direct purchase and sale relationship, instead of adding this network fee through the power grid, resulting in high cost. Many aspects like these need government guidance.

  For another example, we now attach importance to the utilization of hydrogen energy, especially hope that it can transform renewable clean energy, that is, water, wind and light. According to the characteristics of China, water, wind and light are concentrated in the southwest and northwest. Therefore, under the guidance of the government, we established a large-scale project in the world in the past. We called it "West-to-East Power Transmission and West-to-East Gas Transmission". Then, the next step is how to cooperate with this kind of energy and pipe network facilities in existing countries and explore in some ways. By participating in power transmission and gas transmission, and exploring new long-distance transportation of liquid hydrogen, for example, we can clean the energy in the northwest and northeast regions where energy is abundant. Apart from local consumption, because our main and most developed area is in the east, to solve these problems, I think many of them need the government to do a good job.

  Safety standard operation

  Guo Liejin, Academician of China Academy of Sciences:Everyone is very concerned about safety. When we were in primary school, our teacher would tell us that hydrogen would explode. The concentration of hydrogen, the concentration in space is 13% to 90%, and it is likely to explode between them. However, there is a premise for explosion. It needs to see an open flame with sufficient concentration. In Toyota and related enterprises, they all talk about the same car in their reports, which is a car filled with gasoline and a car filled with hydrogen. The chassis structure is the same. They do experiments. Under the premise of causing an explosion, the explosion of the gasoline car is completely destroyed, while the whole structure of the hydrogen fuel cell car is basically unchanged. Therefore, from this safety point of view, hydrogen fuel cell vehicles are much safer than our diesel gasoline vehicles.

  The US Department of Energy and NASA have also done the same experiment. A barrel of gasoline, a barrel of diesel oil and a barrel of liquid hydrogen are shot from a distance, and then various protective facilities are built around to see who has strong explosive ability. The damage degree of the hydrogen tank after explosion is less than half that of the first two tanks, which is between 30% and 40%. What is the reason? Because hydrogen itself is a very light thing, once it is released, it runs into the sky and you can’t find it.

  I have a personal experience. In 1997, I started to build facilities for hydrogen energy research in my State Key Laboratory. At that time, I was also worried about safety. I installed explosion-proof facilities on all the windows of the laboratory, and put hydrogen sensitive elements called sensors at key points around me, and I debugged them myself. Then when the concentration reaches a certain level, it will call the police and the fan will directly discharge the things. But it’s been twenty-two years since this year, and it hasn’t exploded, even ringing.

  We operate according to the rules. Don’t our gas stations have many rules? It is also dangerous goods. Why can we do it well? Hydrogen can also be done very well, and even its destructiveness is much smaller than the fuel we use now. So recently, several hydrogen refueling stations in the world have reported explosions, such as those in California, South Korea and Europe, but when you read its reports, the final result is that the harm to people is minimal. Moreover, it is not the explosion of the fuel body itself, but the auxiliary device, which is caused by irregular operation or irregular installation. So in itself, as an energy source, you can use hydrogen with confidence, but you must of course obey the rules.

  Dong Yang:This safety mainly depends not on whether the fuel can catch fire, but on whether you have mastered the norms and whether human beings have mastered the laws. Therefore, we must pay attention to the safety issue, which is the top priority for us to develop fuel cell vehicles. It is to do it seriously, accumulate experience, solve it, and monitor it with the industrial chain and life cycle, which can completely solve this problem.

L9′ s sales in the first month exceeded 10,000, who dares to argue that it wants to "close down"?

On the second day of the National Day holiday, first of all, I wish you a happy holiday and a safe trip.

On October 1st, while celebrating the National Day, it was time to release the monthly brand column-the sales of new cars.

In September, the brand of new cars was constantly moving, and heavy models were launched one after another. Wenjie M5 EV, Tucki G9, Zero Run C01 and Ideal L8 went on the market, and Weilai ET5 began to deliver. Compared with the situation that opportunities and challenges coexist in August, the new car in September presents a scene full of flowers and vitality.

Tram Lab Anti-Bar Guide: BYD and Tesla have not released their sales in September!

Nezha: 18,005 yuan was delivered in September, with a total of 111,190 yuan this year.

In September, Nezha Automobile delivered 18,005 new cars, a year-on-year increase of 134%.

From January to September this year, a total of 111,190 vehicles were delivered, a year-on-year increase of 168%.

Nezha is definitely the biggest dark horse of new cars this year. In August, Nezha once again topped the sales list of new cars, which is the third month that Nezha won the title of "sales champion". The delivery volume of Nezha U+V series exceeded 18,000 vehicles.

The cumulative delivery volume of Nezha this year has exceeded 100,000, reaching 111,000 vehicles.

As early as August, at the listing conference of Nezha S, Nezha said that the goal of the next stage is to become a new force automobile enterprise with the first cumulative delivery volume in the whole year.

In August, Nezha officially surpassed Xpeng Motors to become the brand with the highest cumulative delivery in the whole year. In September, Nezha continued to lead and expanded its leading edge.

The flagship coupe Nezha S, which shoulders the mission of boosting Nezha’s brand image, has ordered more than 15,000 cars. I look forward to the early delivery of Nezha S, and see if it can help Nezha to remain at the top of the list under the strong impact of "Wei Xiaoli" in the third quarter.

Ideal: Delivered 11,531 in September, and accumulated 86,927 this year.

In September, LI delivered 11,531 new cars, up 62.54% year-on-year and 152.26% quarter-on-quarter.

From January to September this year, a total of 86,927 vehicles were delivered, a year-on-year increase of 57.27%.

In August, because it was at the time when L9 just started to deliver and L8 information began to be published, the ideal entered a short "embarrassing period". The monthly delivery volume was only 4,571 units, which was the second trough of this year, second only to April affected by the epidemic.

But we estimated at that time that this embarrassing period would soon pass with the full delivery of L9. Sure enough, Ideal recovered strongly in September, and delivered 11,531 new cars.

Among them, the Ideal L9 broke Wanda to 10,123 vehicles in the first full month of delivery, helping the Ideal, which ranked 7th last month, to become the runner-up in the leaderboard this month.

Ideal L9 has also become the first China brand vehicle with a monthly delivery volume of over 10,000 and a price of over 400,000.

On September 30th, Ideal held a press conference to launch Li ONE’s replacement model-six-seat medium and large SUV Ideal L8, and released five medium and large SUV Ideal L7.

Both new cars are available in Pro and Max configurations:

The price of L8 is 359,800 yuan for Pro model and 399,800 yuan for Max model, and it is expected to be delivered in November.

The price of L7 is 339,800 yuan for Pro model and 379,800 yuan for Max model, which is expected to be delivered in February next year.

At the first time @ Tram Room Chief had a static experience of the ideal L8. Interested friends can watch the video:

Li Xiang, CEO of LI, once said in Weibo that after the release of information on the L8, the replacement model of Li ONE, Li ONE’s sales volume was obviously affected. Nowadays, the ideal L9 has exceeded 10,000 in the first month, and the ideal L8 has replaced Li ONE to return strongly. The sales performance of the ideal in the fourth quarter will be worth looking forward to.

Zero run: 11,039 in September, and 87,602 this year.

In September, 11,039 new cars were delivered by zero-run cars, up 169.57% year-on-year.

From January to September this year, a total of 87,602 vehicles were delivered, a year-on-year increase of 152.23%.

With excellent cost performance in their respective market segments, the sales of T03 and C11 have been performing well this year. Although the total delivery volume has decreased compared with August, it is already the sixth consecutive month that Zero Run has sold more than 10,000.

On September 28th, Zero Run C01, a medium and large-sized pure electric car, was officially launched and its price was announced. Five new models were launched, with the price range of 193.8-286.8 million yuan.

The new car provides two power layouts: single motor and double motor. The maximum power of the single motor model is 200kW and the peak torque is 360N·m;; The maximum power of dual-motor models is 400kW and the peak torque is 720 N m. Four CLTC cruising ranges are provided, namely, 525km, 606km, 630km and 717km.

Previously, Zero Run officially announced that C01 had seized 100,000 booking orders before listing.

On the day after listing, on September 29th, Zero Run announced that the total value of the newly-added large-scale car C01 exceeded 1 billion. If calculated according to the price of 200,000 cars per car, the number of large-scale cars would be 5,000.

At present, the first batch of delivery of Zero Run C01 has been started, and October will be the first complete delivery month of Zero Run C01. With the blessing of the flagship model, we will wait and see whether the delivery volume of Zero Run C01 in October can reach a new high.

Weilai: The delivery was 10,878 in September, and this year’s total was 82,434.

In September, Weilai Automobile delivered 10,878 new cars, a year-on-year increase of 2%, and the delivery volume exceeded 10,000 for four consecutive months.

From January to September this year, a total of 82,436 vehicles were delivered, a year-on-year increase of 24.2%. In the third quarter, 31,607 new cars were delivered, up 29.3% year-on-year, setting a new quarterly delivery record.

The specific vehicle delivery data are as follows:

A total of 7,729 SUV models were delivered, and 1,895 ES7 vehicles were delivered on the NT2 platform. NT1 platform delivered 5834 vehicles of ES8, ES6 and EC6.

A total of 3,149 cars were delivered, 2,928 cars were delivered by ET7 and 221 cars were delivered by ET5.

With the increase of delivery volume of ES7, the sales of three SUV models of "866" on NT1 platform declined. The most attractive model of Weilai this month is naturally the "explosive model" ET5. On September 30th, the ET5 production car was officially delivered by users, and 221 cars were delivered in a single day.

In September, we participated in the dynamic test drive held by ET5. Friends who are interested in the dynamic performance of ET5 can look back at the previous videos:

On the day of opening the blind lock order on September 9, the order quantity of Weilai ET5 has covered all the production capacity in 2022. According to the information revealed in the conference call of Weilai Q2, ET5 will reach the delivery limit of 10,000 in December, which is a big challenge to Weilai’s production capacity.

In mid-September, some netizens found that Weilai officially ordered the vehicle interface, which increased the display of the expected pick-up time after the current lock list was arranged. Among them, ET5 has the longest waiting time, which is as long as 22-24 weeks.

In October, ET5 will usher in the first first complete delivery month. For an "explosive model" like ET5, there is no need to worry about sales volume. What deserves our attention is the capacity climbing and delivery.

Q: The delivery in September was 10,142, and this year’s total was 45,759.

In September, the series delivered 10,142 new cars, and from March to September this year, a total of 45,759 new cars were delivered.

Following August, the delivery volume of the series of vehicles in the asking sector exceeded 10,000 for the first time, creating the fastest record for domestic new energy automobile brands to break 10,000 in a single month. In September, the delivery volume of the series of vehicles in the asking sector reached a new high, exceeding 10,000 for two consecutive months.

On September 6th, AITO Wenjie listed its first pure electric SUV, Wenjie M5 EV, which is also the third new energy vehicle product released by Wenjie series within one year. The price is 288,600 for the rear-drive standard version and 319,800 for the four-wheel drive performance version.

On the evening after the press conference, the press officially announced that the M5 EV had more than 30,000 order users.

For more detailed information about the M5 EV, you can look back at the article "Far ahead" Tesla, a new car from Huawei. Do you think it’s ok? 》

Tucki: 8,468 was delivered in September, with a total of 98,553 this year.

In September, Xpeng Motors delivered 8,468 new cars.

From January to September this year, a total of 82,436 vehicles were delivered, a year-on-year increase of 74.72%, exceeding the annual delivery in 2021.

The specific vehicle delivery data are as follows:

Tucki P7 delivered 4,634 vehicles, Tucki P5 delivered 2,417 vehicles, Tucki G3i delivered 1,233 vehicles, and Tucki G9 delivered 184 vehicles in the first batch.

In September, the delivery volume of Tucki continued to decline, and the ranking of the list dropped one place to the sixth place. The cumulative delivery of the whole year was opened by the first place, Nezha, with a gap of 12,600 vehicles.

The problem is basically the same as that in August. As the current main model P7 is about to be replaced, consumers are in a strong wait-and-see mood. Therefore, the sales volume of P7 has been tepid, and showed a steady-state slight decline.

However, the new flagship model G9 has not been fully delivered, so the pulling effect on the delivery volume in September is not obvious. On the first day of Tucki G9′ s booking channel in August, the order volume of new cars reached 22,819.

If the production capacity and delivery of G9 can climb smoothly in October, the delivery volume of Tucki in October should be significantly improved.

Krypton: 8,276 was delivered in September, with a total of 39,438 this year.

In August, extremely krypton vehicles delivered 0,018,276 vehicles, an increase of 15.49% from the previous month, hitting a record high in a single month.

A total of 39,438 vehicles were delivered from January to September this year. Since the opening of delivery, the cumulative delivery in history has reached 45,481 vehicles. A total of 20,464 vehicles were delivered in the third quarter, a year-on-year increase of 90%. The average order amount exceeds 336,000 yuan.

In September, there were 30 new stores, the total number of which exceeded 200, and the self-built charging stations covered 100 cities, with a total number of 500 stations.

On September 20th, NVIDIA (NVIDIA) officially released ——Thor, a new generation of smart car chip, at the GTC conference in the autumn of 2022, with a computing power of 2000TOPS.

At the press conference, NVIDIA announced three partners of Drive Thor platform, including Krypton. The new chip will be launched on Krypton vehicles, and Krypton will be the first to use Thor chip for early testing.

Hechuang: delivered 3,011 in September, up 58.2% from the previous month.

In September, Hechuang Automobile delivered 3,011 new Z03 vehicles, an increase of 58.2% from the previous month.

Since the first delivery in August 2021, Lantu has delivered a total of 20,410 vehicles.

Ian: The sales volume in September was 30,016, and this year it totaled 182,321.

Guangzhou Automobile Ai ‘an, the "transfer student" of new cars, comes once a month to reduce the dimension of new cars.

In September, the sales volume of GAC Ai ‘an reached 30,016 vehicles, up by 121% year-on-year, hitting a new high in a single month, with sales exceeding 20,000 for five consecutive months.

From January to September this year, the cumulative sales volume of GAC Ai ‘an reached 182,321 vehicles, up 132% year-on-year.

Reporter’s investigation: Why is the frequent hot search for "privately demolished load-bearing walls" repeatedly banned?

  Beijing, China, October 26 (Reporter Guo Jiali) "Construction started on the first floor, and I can feel a slight shake when I live on the 13th floor." Recently, Ms. Yang from Nanchong, Sichuan reported to Yangguang. com that it cost more than 500,000 yuan to buy this house, another 120,000 yuan to decorate it, and all her savings were spent. I didn’t know that just after living for a year and a half, cracks appeared in the house.

  According to an announcement provided by Ms. Yang, Nanchong Fuli Commercial Management Center and Nanchong Jiahong Property Management Co., Ltd. carried out construction on the first floor of Building No.4 without the consent of the owners. Ms. Yang said that the construction party plans to divide the 5.9-meter-high first floor into two floors, and drill holes with rhinestones, which passed through the load-bearing columns nearly 80 cm thick, causing some houses to crack, posing a safety hazard to the residents of the building.

  Mr. Tang, a resident of the building, said that cracks appeared in the house, which may be no problem at ordinary times, but Sichuan is an earthquake-prone area, and once an earthquake occurs, there will be security risks. The house that ordinary people have worked hard to save money to buy cannot be lived in fear.

  Since the beginning of this year, four people have been detained from the "privately demolished load-bearing wall incident" in Limin Academy Community of Harbin, and then they went to Zhaoqing, Guangdong Province to violently decorate "Open 42 Suites" … … The problem of load-bearing wall being demolished is frequently searched.

  According to the incomplete statistics of the media, among the 49 building collapse accidents in China since 2012, 25 were caused by the unauthorized demolition and modification of the main structure of the existing building or adding stories, changing the use function and increasing the load, accounting for more than 50%.

  In order to eradicate this chaos, on June 9 this year, the Ministry of Housing and Urban-Rural Development issued the Notice on Further Strengthening the Safety Management of Interior Decoration of Urban Houses, clarifying the responsibilities of all parties and relevant departments involved in decoration activities, including design units, decoration enterprises, property service enterprises and local governments.

  Why can’t we tear down the load-bearing wall privately?

  "When we took the new house, there were no such cracks at all. Since the load-bearing pillars were laid on the first floor, the house cracked." Ms. Yang said.

  She said that the merchants on the first floor put the load-bearing columns through all sides, with a diameter of 30 mm, ten holes on each side of the central column and four holes on each side of the side load-bearing column.

  The live pictures and videos provided by Ms. Yang show that the steel bars in the load-bearing columns on the first floor have been drilled, and the upper and lower rows have been drilled through by rhinestones. Cracks have appeared in the kitchen and living room walls of houses on the sixth floor, and cracks have also appeared in the bedroom walls of households on the ninth floor.

  Cracks appear in the wall of the household restaurant (Photo courtesy of the interviewee from Yangguang. com)

  An announcement signed by Ms. Yang to the reporter as "Nanchong Fuli Commercial Management Center" showed that Nanchong Fuli Commercial Management Center indicated that it had entrusted Nanchong Hengrui Testing Co., Ltd. for technical appraisal, and the appraisal conclusion of Nanchong Hengrui Testing Co., Ltd. was that the main structure of Building 4 was in a safe state.

  According to the above announcement, it is suggested to repair the holes in the concrete columns on the first floor immediately, and it is indicated that the Chongqing Design Institute, the original design unit of Building 4, has been entrusted to design the reinforcement scheme, and the drawing review organization has been invited to examine and approve the reinforcement drawings. At the same time, Fuli Center entrusted Sichuan Caiyuan Building Reinforcement Engineering Co., Ltd., which has the professional contracting qualification of special engineering (structural reinforcement), to prepare the concrete beams and columns on the first floor to be restored to their original state.

  However, the community owners do not agree with the announcement. Ms. Yang told the reporter that because the owner did not trust the appraisal entrusted by her, she wanted to apply for the appraisal of the provincial appraisal institute. At present, 51 owners have jointly signed a request for appraisal, but the construction party has been reluctant to sign. At present, the Jialing District Comprehensive Administrative Law Enforcement Bureau said that it would handle the case on November 7.

  "If you break a bone, you can’t stand up." Xue Minghui, deputy dean of the School of Architecture of Harbin Institute of Technology, said that the load-bearing walls and columns are the skeleton of the building. After being damaged, it will cause hidden dangers to the building, and the building will be directly damaged. Its importance is self-evident. It must be made clear that the private demolition of the load-bearing walls is not a moral issue, but a legal issue.

  According to Article 15 of Chapter II of the Regulations on Quality Management of Construction Projects: "The construction unit shall entrust the original design unit or a design unit with corresponding qualification grade to put forward the design scheme before the construction of the decoration project involving the change of the main building body and load-bearing structure. Without the design scheme, the construction shall not be carried out. During the renovation process, building users are not allowed to change the main body and load-bearing structure of the building without authorization. "

  In addition, the first paragraph of Article 5 in Chapter 2 of the Administrative Measures for Interior Decoration of Residential Buildings stipulates: "The following acts are prohibited in the interior decoration of residential buildings: changing the main body and load-bearing structure of the building without the original design unit or a design unit with corresponding qualification grade."

  "Unauthorized transformation may constitute infringement and bear civil liability for compensation. Because the bearing wall is dismantled privately, the whole building is in a dangerous state, which endangers public safety and is suspected of bearing criminal responsibility, which constitutes a crime of endangering public safety by dangerous means. " Lawyer Li Baolian of Beijing Jingshi Law Firm said.

  On October 22, Ms. Yang told reporters that the construction party had stopped work on August 29 due to the opposition of the owners. On September 1st, Jialing District Comprehensive Administrative Law Enforcement Bureau delivered a rectification notice to Fuli Center.

  Why is there a constant controversy over privately demolishing the load-bearing wall?

  Not only Ms. Yang, but also Mr. Chen from xinluo district, Longyan City, Fujian Province, is facing the problem of "privately demolishing the bearing wall" in the same building.

  On October 20, Mr. Chen told the reporter of Yangguang. com that the owner of the 25th floor of the residential area owned two houses on this floor. In order to connect the two houses into one, during the renovation, the owner removed the four load-bearing walls between the living room of one house and the kitchen of another house. "The load-bearing walls that have been demolished here are basically determined. As the householder refused to let in, whether the load-bearing wall at the passage between the two units was damaged has not yet been determined. "

  Xue Minghui, after checking the construction drawings provided by Mr. Chen, said that the four demolished places are wall battlements, which are not a big problem at ordinary times, but may be dangerous under special circumstances. Shear walls, also known as wind-resistant walls and earthquake-resistant walls, are located in the passage between the two houses, which have the function of resisting typhoons. Destroying the shear walls will affect the bearing capacity of the building and cannot be removed at will.

  Floor plan of the owner’s two houses on the 25th floor (Photo courtesy of the interviewee sent by Yangguang. com)

  "Why did the original design unit or the design unit with the corresponding qualification grade not issue a professional design plan, and the property was allowed to start construction?" Many owners asked about the residential property in the WeChat group.

  In response to the owner’s query, the property said in the owner group of Building No.10 that the behavior had been discovered during the inspection, and issued a rectification notice on August 30 and informed the Urban Management Bureau, and said that the Longmen Law Enforcement Brigade of the Urban Management Bureau had been to the site for disposal.

  During this period, many residents in Building 10 complained through "e Longyan". On September 13, Longyan City Administration Bureau began to reply to the complaints one after another: "The Longmen Law Enforcement Brigade of Longyan City Administration Bureau intervened in the investigation on September 6 before receiving the complaints. Our team’s law enforcement officers asked the owner to rectify and restore the demolished wall, and the owner began rectification on September 10. "

  However, the owners are not satisfied with the reply. "Let the business owners recover on their own, and can they meet the requirements of bearing capacity after recovery? Why not publish a professional appraisal and repair plan? " Mr. Chen said.

  In the interview, the reporter found that whether the appraisal is authoritative and the later professional rectification plan is issued, and whether reasonable compensation is implemented is the focus of controversy.

  Lawyer Wang Xinyue of Beijing Haotian Law Firm said that the reason for the dispute is that even if the owner receives the rectification notice or administrative punishment decision from the law enforcement unit, there may still be problems in actual performance. For example, the owner is not sure whether the rectification and repair plan is standardized or whether the rectification and repair plan meets the bearing capacity requirements.

  She believes that law enforcement units should actively perform their duties, eliminate the harmful consequences and continue to follow up after issuing the Notice of Order (Time Limit) Correction, and combine various means such as investigation, fine and transfer to the public security department. If necessary, a third-party rectification plan can be introduced, and the rectification costs will be borne by the violator. At the same time, strengthen the intensity of administrative law enforcement and improve the quality of administrative law enforcement.

  Why are private demolition of load-bearing walls repeatedly prohibited?

  Since the beginning of this year, many "privately demolished load-bearing walls" incidents have been on the hot search.

  At the end of April, in a 31-storey residential building in Limin Academy Community, Songbei District, Harbin, tenants smashed the load-bearing wall privately during renovation, resulting in cracks in the whole building. In the evening, more than 200 households were evacuated. According to CCTV news, on May 9, the public security organs took criminal compulsory measures against four responsible persons according to law.

  Just in the past month, at the end of May, some people reported that on the second floor of an apartment building in Yuegong Mansion, Wuyue Square, Sihui City, Guangdong Province, Yao, the owner of 42 apartments on the whole floor, demolished the partition wall without obtaining a construction permit, and illegally constructed about 700 square meters. On June 6th, the official WeChat of the Propaganda Department of Sihui Municipal Committee, WeChat official account, released a description of the "Sihui Release", ordering it to stop construction immediately and make corrections within a time limit.

  Xue Minghui said that load-bearing walls generally refer to walls used to bear vertical loads in brick-concrete structures. At present, new buildings are rare, mainly some multi-storey houses built in the last century. Multi-storey public buildings are generally frame structures, which are supported by columns. High-rise residential buildings are generally shear walls, which are supported by vertical and horizontal loads. Some people understand shear walls as load-bearing walls.

  Why is it that private demolition of load-bearing walls is repeatedly prohibited? He believes that from a dialectical point of view, first, the functions of existing buildings can not meet the needs of social development, and the space can not meet the requirements of new commerce and residence, which needs to be expanded, but it is limited by the wall. Second, due to the lack of popular science in architecture, many people don’t know which walls can be moved, which can never be moved, and which can be partially changed, such as opening doors and windows, which helps those who don’t know the building structure to avoid falling into the predicament of huge compensation and disputes. Third, the inadequate supervision of the property and related departments on the decoration process is also one of the reasons for this phenomenon.

  "Once there is a problem with the load-bearing wall, the property will also bear the responsibility, which is a dereliction of duty." A property manager said that before the renovation, the decoration masters all had house design drawings, and they knew which were load-bearing walls. "If it is not deliberately demolished, the decoration master will not move the load-bearing wall."

  In Xue Minghui’s view, it is necessary to raise residents’ awareness of the rule of law for such problems. "Let everyone know that this is not a moral issue, but a legal issue."

  How should the load-bearing wall "bear the load"?

  "Not all load-bearing walls can be dismantled." In Xue Minghui’s view, many buildings can be demolished by structural reinforcement, but this requires special institutions to identify, design and construct. In addition, because a certain safety factor is reserved in the structural design of buildings, sometimes accidents will not occur when some load-bearing walls are removed. For example, the load-bearing wall on the top floor of the building does not have much load on it, and even if it is removed, the problem is not great.

  He said that it is unclear that the most unfavorable conditions, such as earthquake resistance, too many people in the room and uneven load, will be taken into account when designing the building structure. However, this has also caused many people a misunderstanding that some load-bearing walls can be removed, or at least some parts can be removed.

  In order to curb the illegal acts of interior decoration, on June 9 this year, the Ministry of Housing and Urban-Rural Development issued the Notice on Further Strengthening the Safety Management of Interior Decoration of Urban Houses (hereinafter referred to as the Notice), which further clarified the responsibilities of all parties and relevant departments involved in the decoration activities, including design units, decoration enterprises, property service enterprises and local governments.

  The Ministry of Housing and Urban-Rural Development issued the Notice on Further Strengthening the Safety Management of Interior Decoration of Urban Houses.

  After the promulgation of the Notice, some cities have taken action. For example, the comprehensive administrative law enforcement team of Luodian Town, Baoshan District, Shanghai has set up a special working group to lead the new owners to identify the load-bearing structure of the house on the spot in each newly delivered community, and to answer questions on the spot by explaining the case and explaining it in a simple way, so as to turn "compulsory afterwards" into "prevention and control beforehand".

  "This is not a joke, we can’t afford this responsibility." A property manager said that no matter from which point of view, this is harmful to others. If there is a crack in the internal structure of the wall, the residents of the whole building are in danger.

  The above-mentioned managers said that before the renovation, they would tell the owners never to move the load-bearing wall. During the renovation, the property personnel should also check it out. If there are renovation tenants who can’t open the door due to frequent construction, they should pay attention. If the owner is found to have dismantled the load-bearing wall privately and refuses to stop it, he will be told to stop the decoration immediately and force the water and electricity to be cut off. In addition, the property will also inform the doorpost and refuse the decoration master to enter the community. After the load-bearing wall is restored, the construction can continue.

  Li Baolian said that property service enterprises should give full play to the role of "whistleblower" and "night watchman", encrypt the frequency of inspections in their daily work, dissuade and stop violations immediately when they are found, and promptly report to relevant departments for legal determination and handling. Government supervision departments should strengthen the supervision of decoration enterprises, and strictly investigate unqualified, borrowed or exceeded qualifications to undertake decoration projects.

  She said that once it is found that someone has dismantled the load-bearing wall privately, the owner can bring a lawsuit to the people’s court where the house is located according to the Civil Code, requesting the actor to stop the infringement, remove the obstruction, eliminate the danger, restore the original state and compensate for the losses.

Sichuan News Network, Chengdu, January 21 ST (Reporter Dai Yuling’s photo report)On the eve of the Spring Festival in 2020, the sound of reeds came from the "Jiming Three Provinces" at the junction of Yunnan, Guizhou and Sichuan provinces, and the Jiming Three Provinces Bridge across the Chishui River was finally opened to traffic! "Open to traffic! Open to traffic! " Villagers in Chahe Village, Shuiliao Yi Township, xuyong county, Luzhou, used musical instruments to spread the joy to Yunnan across the bridge.

One minute’s drive and 300 meters’ walk. The Three Provinces Bridge is open to traffic!
The "three provinces of crowing" is located between Sichuan, Yunnan and Guizhou provinces. It is said that there is a story that "the golden rooster crows all over the three provinces". However, although it is said that a rooster can be heard in three provinces, the traffic between the three places is a big problem. Throughout history, this place has been a geographical corner, with traffic jams and extremely difficult communication.
The local people told reporters that because the Chishui River and Weihe River meet here, in the past, if they wanted to reach Yunnan from Sichuan, they had to take a detour to Tanchang, paddy fields, Potou and other towns and villages and drive for two and a half hours. It takes one and a half hours to climb the mountain and cross the river, but there are some safety hazards, such as windy and rainy, rising water, foggy river, simple ferry structure and limited life-saving equipment.
Now, after the completion of the Jiming Three Provinces Bridge, the travel mode of people’s fishing boats crossing the river has been completely changed, and the cross-strait traffic distance has been shortened geometrically. It takes only one minute to drive across the bridge to reach the other side, and the walking distance is only 300 meters, which greatly saves travel time and will completely eliminate the safety hazards of cross-strait residents crossing the river.
"It is open to traffic before the Spring Festival, so it is convenient to visit relatives in the New Year." Wang Sicai, a villager in Tianba Village, Shuiliao Township, dressed in Miao costumes and blowing reeds onto the bridge, told reporters excitedly that the wishes of several generations have finally come true and he is happy to express it with music. "In the past, I had to transport the crispy plums to the other side for sale. I could only carry forty or fifty kilograms and walk for four or five hours. Now, it can be transported in ten minutes by truck. There is also a farmhouse in the village to entertain tourists. In the future, walnuts and crisp plums will be expanded, and more and more villagers are willing to return to their hometowns to start businesses. The bridge has passed, which has brought us many good opportunities. "
The reporter learned that the design speed of the bridge is 40 km/h, the design load is highway -I, the bridge length is 286.4 meters, the net span of the main bridge is 180 meters, and the main arch ring adopts cantilever casting construction technology. The width of the bridge deck is 11.5m (9m carriageway+1.25m sidewalks on both sides), the total length of the approach road at the bridgehead of Sichuan Bank is 637.88m, the total length of the approach road at the bridgehead of Yunnan Bank is 140.6m, and the total length of the route is 1041.3m, with two lanes in both directions.

 Inter-provincial group year becomes simple "full of love journey" love chartered car
The reporter learned that it coincides with the Lunar New Year holiday. With the full completion of the Jiming Bridge in three provinces, at the strong request of the people on both sides of the strait, the Transportation Bureau of xuyong county, Sichuan Province and the Transportation Bureau of Zhenxiong County, Yunnan Province reached a framework agreement to connect buses, and on January 21st, three "full journey" love chartered cars were launched. Next, the transportation departments of the two places will improve the relevant procedures as soon as possible, and start customized passenger transportation from Shuiliao Township, xuyong county, Sichuan Province to Potou Town, Zhenxiong County, Yunnan Province, so as to provide convenient, safe, warm and comfortable travel services for the people on both sides of the strait, so that the local people can truly feel the care of the transportation departments and let the people have more sense of gain, satisfaction and happiness in the transportation field.
"Dead ends" and "revitalization" of tourism resources will inject new vitality into rural revitalization.
He Xiaotao, deputy director of the Agricultural Construction Department of the Highway Bureau of the Sichuan Provincial Department of Transportation, told reporters that in addition to facilitating the travel of ordinary people, the completion and opening of the Jiming Bridge in the three provinces is also conducive to promoting the economic development of the three provinces on both sides of the strait. The poor wumeng mountain, where the Jiming Three Provinces Bridge is located, has been a traffic corner for thousands of years, and has always been a backward and poor area in history. The xuyong county of Sichuan and Zhenxiong County of Yunnan, which it connects, are all state-level poverty-stricken counties, facing Qixingguan District of Bijie City, Guizhou Province across the river. The coal and pyrite in Yunnan can’t be delivered, and the crisp plums and tobacco in Xuyong, Sichuan are difficult to transport. The inconvenient transportation makes many scenic and ingenious tourism resources in Sichuan, Yunnan and Guizhou unable to meet each other. The completion of the bridge will help to implement the poverty alleviation policy, which will further promote the development of coastal economy and industry and increase farmers’ income; It will further help the development of the tourism industry, and all the "dead ends" of local rich tourism resources will be "revitalized"; It will further boost wumeng mountain’s poverty alleviation and prosperity, win the battle against poverty, and inject new vitality into rural revitalization; It will further supplement and optimize the layout of inter-provincial passages between Sichuan and Yunnan, and promote the development of regional economic and social integration.
In addition, the bridge is the inheritance of the red spirit. Chishui River and Ancient Yi Holy Land. Once it was the marching place where the Central Red Army crossed Chishui, and the famous three provinces of Jiming were held. The completion of the bridge will further promote the development of local red tourism.

It is estimated that by the end of 2020, car crossings and passenger crossings with annual traffic volume exceeding 50,000 passengers can be basically eliminated in Sichuan.
There are many rivers in our province, and people in some economically underdeveloped areas have to travel by ferry. According to statistics, by the end of 2012, there were 1718 ferries in the province, which brought a lot of inconvenience to people living and traveling along the river and facing the water. In order to eliminate the hidden dangers of ferry transportation and improve the production and living conditions of the masses along the river and near the water, the provincial party Committee and government attach great importance to the construction of ferry bridge reconstruction project as a major livelihood project.
With the completion of a large number of ferry bridge-changing projects, the water travel conditions of the ferry in our province have been greatly improved, the potential safety hazards have been effectively rectified, and the transportation network has been further improved, which has provided a strong transportation guarantee for the county’s economic and social development and farmers’ prosperity.
It is estimated that by the end of 2020, car crossings and passenger crossings with annual traffic volume exceeding 50,000 passengers can be basically eliminated, effectively solving the troubles of people near the water for wading or long-distance detours. He Xiaotao told the reporter, "The Jiming Three Provinces Bridge is also the 36th highway passage on Chishui River, and it is also another highway outlet in our province. Its completion has provided strong road traffic support for promoting high-quality poverty alleviation in the contiguous poverty-stricken areas of Wumeng Mountain and promoting the" four-way expansion and global opening "strategy of the provincial party committee and government."

Skiing danger? This is actually a misunderstanding, please put away the raiders.

The Beijing Winter Olympics is still in full swing. See if you are not addicted after all, or do it-put on skates and snowboards, and feel the thrill of speeding down on the ice or snow, which is the most enjoyable moment for ice and snow enthusiasts.
However, any sport is fun and dangerous, and ice and snow sports are no exception.
Damage is not divided into novice and expert.
Xiao Jing and his friend Lao Wu went skiing. Because Xiao Jing usually skied less, he has been leading and protecting Lao Wu to slide down the primary road. By the last slide, everyone was tired, but Lao Wu felt it was a pity that he hadn’t skated the advanced road yet, so he went to the advanced road. Xiaojing didn’t rest, and he continued to slide the primary road …
Coincidentally, both of them accidentally fell down. Xiao Jing said that he was too tired, and there was no one to guide him. He just felt that there was something wrong with his movements when he started sliding, and he soon hit the guardrail. Lao Wu, who has several years of skiing experience, sprained his knee after falling because he was too fast on the advanced track and didn’t do enough corner movements.
After examination, Xiao Jing’s knee was slightly sprained, but Lao Wu, who has more skiing experience, was injured more seriously because of too fast, and the anterior cruciate ligament of his knee was broken, so he had to undergo arthroscopic reconstruction.
The situation of Xiao Jing and Lao Wu is very common on the snow field. In the snow season of 2017-2018, the number of skiers in Yanqing Ski Resort in Beijing reached 297,000, and 428 people needed emergency treatment due to injuries, of which 61 people needed to be transferred to hospital for treatment. There have also been cases of death caused by skiing accidents in China.
90% of "Ice Man" is a novice.
90% of ordinary ice and snow sports fans in China are beginners, and most of them have not received professional guidance from regular coaches and have not fully mastered skiing skills. When an emergency happens, due to the lack of sufficient coping experience and skills, people often panic and mishandle, which leads to their own injuries or injuries to others.
Although some people have several years of experience in ice and snow sports, they are blindly confident and choose to slide on the snowy road that does not match their ability; Even some experienced skiers blindly challenge difficult skiing movements in pursuit of excitement, pursue the pleasure of flying down, leave safety behind and eventually fall into pain.
When doing ice and snow sports, what conditions are likely to lead to sports injuries?
01 Lack of risk awareness
Most ordinary ice and snow lovers are not fully aware of the dangers of this sport and are not fully prepared for the potential risks. The correct way is to participate in ice and snow sports with good mental state and high concentration.
02 technical action is not standardized
Mastering the correct basic technical movements is the premise to avoid injury accidents.
03 insufficient preparation activities
Most people don’t have the good habit of warming up and doing adequate preparatory activities before exercise, and don’t realize that warm-up exercise is an important means to reduce sports injuries. In the cold outdoors, due to the influence of low temperature, great changes have taken place in muscle expansion and contraction function, cardiopulmonary adaptation, blood circulation and joint flexibility. Warm-up and warm-up activities have a strong protective effect on human body, especially joints, which can increase muscle temperature, lengthen muscle fibers, increase joint flexibility, improve the functions of various organs and tissues of the body, make the human body enter the exercise state faster and more smoothly, and reduce the occurrence of sports injury accidents.
04 Too much exercise and too long time.
First of all, excessive exercise can easily lead to muscle fatigue, leading to the deformation and irregularity of skiing movements, and then accidents, ranging from muscle ligament damage to fracture and even vascular nerve damage; Secondly, long-term excessive exercise will lead to joint and muscle strain.
05 failed to replenish energy in time.
During skiing, the body consumes a lot of energy, so we must pay attention to supplementing nutrition and energy, never continue to exercise in poor physical condition, and avoid taking part in strenuous skiing during diet control or "weight loss". Good physical fitness is maintained by adequate nutrition. Without good physical fitness as a guarantee, any beautiful skiing skills are difficult to show.
If the above mistakes can be avoided, ice and snow sports are actually not dangerous.
Skiing and first aid.
In mass ice and snow sports, knee joint injury ranks first, ankle joint injury and shoulder joint injury rank second. Most people who go to the sports medicine department of the hospital to see the emergency department have these kinds of injuries.
The most common knee injuries are medial collateral ligament rupture, anterior cruciate ligament rupture, meniscus tear, patella dislocation, etc. Ankle injuries are mainly ankle lateral collateral ligament tears and ankle fractures caused by ankle sprain.
The posture of tumbling and suddenly falling on one’s back during skiing may cause injuries to the head and neck, lumbar vertebrae and sacrococcygeal vertebrae.
Fracture is also a common sports injury, and the most common parts are wrists, ankles, knees, lumbar vertebrae and cervical vertebrae.
In addition, although joint dislocation and cutting injury are not universal, the harm is enormous.
Let’s talk about the common types of ice and snow sports injuries and suggestions for treatment.
01 meniscus injury of knee joint
Torsion of knee joint can cause meniscus tear and ligament rupture, and the injured person will have obvious symptoms such as knee joint pain, swelling and limited movement, and in severe cases, the joint will not be straightened. It is suggested to consult a sports medicine doctor in a big hospital as soon as possible. Many people may need arthroscopic surgery.
Fracture of anterior cruciate ligament of knee joint
When falling on the ice and snow, if the strength of spraining the knee joint is relatively large, it may lead to the injury of the medial collateral ligament and the rupture of the anterior cruciate ligament. Once the anterior cruciate ligament breaks, the knee joint will be severely painful and the joint will swell up. If you endure it, it will lead to instability of the knee joint. Generally, arthroscopic auxiliary surgery is needed to rebuild the cruciate ligament. It is recommended to seek medical treatment as soon as possible, and find a specialist to make a clear diagnosis and determine the treatment plan.
03 medial collateral ligament rupture of knee joint
The medial collateral ligament injury mostly occurs when the knee joint is slightly flexed and the calf is suddenly everted. After the medial collateral ligament is broken, the medial knee joint is swollen, local pain and subcutaneous congestion. If the swelling of the medial side of the knee joint is particularly serious, and besides the obvious tenderness of the medial side of the knee joint during physical examination, the opening feeling is also very obvious, then it can basically be diagnosed as a complete rupture of the medial collateral ligament, which may be accompanied by anterior cruciate ligament injury. If it is not completely broken, you can not do surgery, conservative treatment with long leg plaster knee flexion 30 inversion (preferred) for 3~4 weeks, and then change the adjustable chuck support; Or a movable support with a chuck is fixed for 6-8 weeks; If MRI shows that the deep and shallow layers are completely broken, or even some ligaments have been embedded in the joint space, emergency surgery is needed.
04 ankle sprain
The incidence of ankle sprain is very high, which is generally varus injury, which is easy to cause ligament damage of the lateral ankle, and severe ankle sprain will cause ankle fracture.
After on-site treatment of ankle sprain, you should seek medical advice in time. It is best to go to a professional department in a big hospital, such as sports medicine or ankle surgery. It is best if you can find a doctor who specializes in foot and ankle in sports medicine. The doctor will give a more reasonable treatment plan according to the severity of the injury, which is conducive to the follow-up rehabilitation of patients. Surgical treatment is the first choice for patients with lateral collateral ligament of ankle joint combined with joint capsule tear, especially for athletes and young people who like sports. Ligament rupture is serious, or for ankle fracture, conservative treatment, emergency operation or delayed operation should be chosen according to the specific type and severity of the fracture.
