Yesterday, Chengdu Business News "83? Spring? The top of the Lushan? Building strong? The report caused a lot of concern. Among them, stacked rubber seismic isolation bearing can effectively improve the level of seismic defense is the focus of attention. Chengdu Business News reporter learned from the provincial housing and urban-rural construction department, Sichuan has more than 100 buildings using stacked rubber seismic isolation technology.
But because the current seismic isolation technology is still only ? Encourage the use of ?
Advantages obvious: can be anti-seismic can also bring economic benefits
The reporter learned that the building seismic isolation and mitigation technology is one of the Japan, New Zealand, the United States and other countries commonly used in the construction of anti-seismic technology, but also mature and reliable suitable for the Sichuan earthquake-prone reality of the advanced technology. The biggest advantage of this technology is that it can effectively improve the level of seismic defense. For example, the Civil Aviation Southwest Air Traffic Control Bureau building at Shuangliu Airport also utilizes seismic isolation technology. According to the investigation, on the 20th day, the morning watchman almost did not feel the building shaking, to ensure the normal operation of the airport flight air traffic control system.
Second, this technology has obvious economic benefits.
An expert from the Sichuan Provincial Department of Housing and Urban-Rural Development introduced the seismic isolation technology can effectively improve the seismic grade, but also save the cost of the project, at the end of the last century by the then Ministry of Construction included in the major scientific and technological achievements. To this end, the Sichuan Provincial Department of Housing and Urban-Rural Development requirements in the Wenchuan earthquake reconstruction vigorously promote the application of the new technology, new materials. Among them, schools, hospitals and other public **** building has become a key target to encourage the application. At present, China's highest seismic isolation and damping building Guangyuan Central Hospital has just been completed and used. Wenchuan Second Primary School, Yingxiu Primary School, Yingxiu Middle School, Yingxiu Center Health Center and other public **** building has been completed. In Chengdu local, this year's debut of the Chengdu Museum is also Sichuan post-disaster reconstruction of the largest single building seismic isolation and damping technology application project.
Promotion blocked: call for the inclusion of mandatory promotion
Although the total number of buildings using seismic isolation technology in Sichuan has been more than 100, but the expert believes that this number of reconstruction of tens of thousands of projects compared to the Wenchuan earthquake, or too little. The promotion of seismic isolation technology is hindered by four main reasons: First, some experts do not support; Second, some local officials do not know enough; Third, the policy to promote the efforts of insufficient; Fourth, the designers of the training is not enough.
March 19 this year, the provincial people's government adopted the 4th executive meeting of the "Sichuan Province, construction projects to resist seismic disaster management approach", and is intended to be June 1 this year shall come into force. Among them, the content of Article 29 ? Encourage the construction of seismic new technologies, new techniques, new materials, new equipment, scientific and technological research, and promote the application of earthquake mitigation in line with local practice, seismic isolation structure, steel structure, assembly structure, wood structure and other building structure seismic technology. The people's governments at or above the county level and their relevant departments shall promote the application of new technologies, new techniques, new materials and new equipments for seismic-resistant defense in accordance with the state regulations.? Provincial Housing and Urban-Rural Development Department and other relevant administrative departments shall, in accordance with the law, release the building seismic new technologies, new techniques, new materials, new equipment for the promotion of scientific and technological achievements of the project, the scope of application and restriction, prohibition of the use of technology?
? China's existing laws and regulations for the application of new technologies are encouraged, supported, so in practice, it is difficult to get good implementation results. And the example of Lushan County People's Hospital is the best case of seismic isolation technology urgently needs to be included in the mandatory promotion.? This expert said that legislation should be passed to public **** building mandatory promotion of seismic isolation technology.
