by At the beginning of 2020, hundreds of millions of Internet users “cloud supervisor” for 24 hours to cheer for the construction of Wuhan huoshenshan hospital and leishenshan hospital.
In more than 10 days, two hospitals have sprung up.
Behind the amazing “China speed” is the rise of “China assembly” power.
In recent years, precast buildings in Hainan have shown a good development trend and played an important role in promoting the transformation and upgrading of the construction industry and promoting green development in the field of urban and rural construction.
Click on the picture to watch the video reporter Li Yifei: precast building refers to the building built by prefabricating some or all components and accessories in the factory and then transporting them to the construction site.
Compared with the traditional construction method, the assembled type is not affected by bad weather and the construction period is more controllable.
In the production workshop of Haikou precast factory of China Railway fourth Bureau, the reporter saw that the precast components produced on the assembly line can be transported to the construction site for construction after high-temperature steam curing and natural curing in the curing kiln.
It has many advantages, such as small error, eliminating material waste, reducing construction waste, reusable resources and so on.
Person in charge of Haikou precast factory of China Railway fourth Bureau, Wuyang: since the government vigorously promoted the equipment building, our factory has produced precast components for the construction market in Hainan.
At present, the annual production capacity of the factory is about 35000 cubic meters and the output value is 120 million.
Tan Xincheng, director of the Architectural Design Institute of Hainan construction project planning, design and Research Institute: such a production mode will save a lot of labor.
At the same time, it will play a very good role in environmental protection, economy, consumption reduction, energy conservation and so on.
The newly capped Haikou changxiushijia project, with a total construction area of about 132000 square meters, will build 1027 sets of residential commercial housing.
The assembly rate of the project reached 52%, and it took only 339 days from the commencement to the full capping of the main structure, which is more than one year shorter than that of conventional projects.
Huang Mengliang, Haikou changxiushijia housing project manager: for the precast building, we reach the 8th floor, and then we can start the construction of our partition board, which will save us at least three months.
Haikou Jiangdong new area level 1.5 enterprise port project adopts the construction technology of “cast steel structure + integrated modular system”, which transfers a large number of parts and components to the factory for completion, realizes the “factory + site” parallel construction, reduces carbon emissions from the whole process of production, transportation and construction, and reduces environmental pollution.
Feng Jian, Party Secretary of Hainan Branch of China Construction Science and Engineering Group Co., Ltd.: the whole project is equivalent to 23000 square meters in 73 days.
Compared with traditional buildings, we can reduce the emission of construction waste by 60%.
In 2021, the precast building area of Hainan was 22.8 million square meters, doubling for four consecutive years.
In 2020, the Hainan provincial Party committee and provincial government included the precast building in one of the four landmark projects of the national ecological civilization pilot zone (Hainan).
At the same time, the Provincial Department of housing and urban rural development has continuously improved supporting policies, standard system, production capacity layout and talent team construction, and accelerated the promotion and application of precast buildings.
In 2021, Hainan’s precast building area reached 22.8 million square meters, doubling for four consecutive years.
According to the plan, by 2025, precast buildings in Hainan will account for more than 80% of new buildings.
Chen Yun, vice president and doctoral supervisor of the school of civil and architectural engineering of Hainan University: vigorously strengthen the training of industrial workers, improve the construction quality of precast construction site, and further improve the relevant technical and industrial standards of Hainan Province.
After several years of development, Hainan Province has actually been at the forefront of China in terms of precast buildings.
RECOMM.
