In the next step, we will focus on the research, development and production of cast whole industry chain products, including laminated plates, stairs, shear walls, partitions, balconies, etc.

Huacai • Haikou Bay twin towers are 150m and 120m high respectively, with an overall project volume of 173000 square meters.

At present, Lingao gold medal port construction Industrial Park is promoting the construction of cast components Build the whole industrial chain development of R & D, design, manufacturing, operation and maintenance..

At present, the park has started four new construction industry projects, all of which are planned to be officially put into operation before the end of the year.

At present, Hainan Province is improving the production capacity layout of precast buildings and promoting base construction.

Liu Lianwei, deputy director of Hainan Provincial Department of housing and urban rural development, said in an interview with the media that precast buildings not only meet the development requirements of Hainan’s strategy of building a national ecological civilization pilot area, but also have the advantages of high degree of industrialization, short construction cycle, convenient transportation of components and parts, recyclable utilization in the whole life cycle, green environmental protection and so on.

The reporter learned from the Department of housing and urban rural development of Hainan province that since 2018, Hainan has continuously improved the top-level design architecture at the provincial level, such as supporting policies, standard system, capacity layout and talent team construction of precast buildings.

“The phase I project of the base has a total investment of 200 million yuan and covers an area of 100 mu.

At the construction site of Yangpu shipping building, a landmark project in the park, the tower crane is hoisting the precast floor slab.

What is the development progress of precast construction industry? Fabricated building materials shall be processed and formed in the prefabrication base first.

2 company, introduced that the assembly rate of the project reached more than 50%.

Mr.

“In the design, considering the location of the plot, geological structure and overall quantities, it is decided to adopt the all steel structure.” Shen xueyang introduced that the most significant advantages of all steel structure are saving construction period, cost and space.

In terms of classification, it mainly includes precast concrete structure, steel structure, modern wood structure buildings, etc.

In Yangpu Economic Development Zone, Hainan free trade port, precast buildings are also widely used.

Under the condition of almost zero foundation, the project area determined to be constructed by assembly in the province in 2018, 2019 and 2020 is 824.35 million square meters and 11 million square meters respectively, which has doubled year by year in recent three years.

After it is put into operation, the production capacity of cast components is expected to reach 100000 cubic meters per year.” China Railway Construction Construction Development Co., Ltd Zhang Yu, deputy general manager of (Hainan) Co., Ltd., said that at present, the main business is cast PC components.

“He climbs almost at the speed visible to the naked eye, and the building speed is quite fast.” Data figure: Century Bridge.

She introduced that the implementation of precast buildings, on the one hand, reduces the workload of a large number of reinforcement processing and concrete pouring and tamping on site, and effectively reduces noise, dust and dust pollution; On the other hand, it greatly shortens the flow operation cycle of the project and saves 90 days for the whole project duration.

Luo Yunfei photographed workers doing interior decoration for the industrial park in Hainan Lingao precast building industrial park of China Railway Construction Group.

Shen xueyang, representative of the project owner and assistant general manager of Hainan Huacai Investment Holding Co., Ltd., told reporters that the reason for the rapid growth of the twin towers: it is a cast building with all steel structure.

Hainan takes precast buildings as an important measure to promote the transformation and upgrading of the construction industry and one of the important supporting work of carbon peak and carbon neutralization, It will be included in the four landmark projects of the national ecological civilization Experimental Zone (Hainan) (construction of national tropical rain forest park, promotion of new energy vehicles, total ban on plastic and development of precast buildings).

Workers in the pilot area of Hainan Lingao precast construction Industrial Park of China Railway Construction Group are building precast components.

In recent years, the state has intensively issued policy documents on the promotion of precast buildings, and Hainan Province has also actively refined and improved policies and measures.

According to the development plan of construction industry modernization (precast building) in Hainan Province (2018-2022) In addition to the existing precast building industrialization bases in Chengmai, Ding’an, Wanning and Sanya, in principle, the new production capacity of precast building parts and components will be centrally distributed to Lingao gold port development zone.

By the end of 2021, the precast building area has exceeded 20 million square meters, which is expected to double year by year for four consecutive years.

At the same time, due to the use of precast buildings, Hainan Province will reduce the source of construction waste by about 220000 tons in 2020.

Data drawing: the upper main body of the precast building is under construction.

What’s good about precast buildings photographed by Wang Xiaobin? Compared with traditional building methods, precast building has many advantages: it will greatly reduce dust, noise and sewage during on-site operation, and can save 80%, 70%, 20%, 70% and 20% of water, materials, time and land, which is very in line with the national energy conservation and emission reduction goal.

Compared with concrete structure, the project cost is saved by 10% and the house acquisition rate of the project is increased by 3%.

The products are based in Hainan, facing the Great Bay area of Guangdong, Hong Kong and Macao, and radiating Southeast Asia.

because it adopts standardized design, factory production, assembly construction, information management and intelligent application, it is the representative of modern industrialized production mode.

Lifting Clutches

At present, the proportion of precast buildings in new precast buildings still has great room for improvement.

What is precast building? Precast building refers to the transfer of a large number of on-site operations in traditional construction methods to factories, and the processing and manufacture of building components and accessories in factories (such as floor slab, wallboard, staircase, balcony, etc.), transported to the construction site through “building blocks” A building installed in a manner.

Li, who drives through Haikou century bridge every day, is often attracted by a twin tower under construction.
