Airport supporting projects "build building blocks"! The first prefabricated flood control box culvert project in Shanxi Province was successfully completed

The prefabricated buildings on the ground are not new, but have you seen the prefabricated projects underground? On June 26, at the construction site of the prefabricated flood control box culvert project of the Taiyuan Wusu International Airport Airport Supporting Project (Jinzhong Region) PPP project, with the completion of the last section of prefabricated box culvert roof concrete pouring, the first prefabricated prefabricated flood control box culvert project in Shanxi Province was successfully completed.

Nowadays, "prefabricated buildings" are not a new term in the field of infrastructure construction. Because of their unique advantages such as energy saving, high efficiency and environmental protection, they have been favored by the industry in recent years. This prefabricated flood control box culvert project was implemented by Shanxi Jiantou Construction Industry Co., Ltd. "Prefabricated buildings mainly include prefabricated concrete structures, steel structures, modern wooden structures, etc. The total length of the box culvert project we implemented this time is about 500 meters, the structure is a prefabricated concrete structure, and the underground box culvert is designed as a four-cabin structure. "Li Jinhua, 30 years old this year, is the relevant production person in charge of the project. He has been engaged in construction project management in the construction front line for seven or eight years. His personal experience of prefabricated buildings is "fast speed, high efficiency, and less labor." 

▲Hoisting "building blocks" on the construction site

"The construction length of each section is 21 meters, which is not affected by objective factors. The construction period of the cast-in-place construction will take 5 days at the fastest, and the number of workers will be about 60. The use of prefabricated buildings not only reduces the number of workers by half, but also shortens the construction period by half. Li Jinhua said that compared with traditional construction sites, the construction environment is also very different. Without the scene of building materials such as sand, cement, and formwork being piled up everywhere, civilized and safe construction is more guaranteed.

Not only that, compared with the wooden formwork used in traditional construction sites, the aluminum formwork used in this project also has the characteristics of easy erection and dismantling, fast turnover, and many times of use. The entire construction process is safe, clean and tidy, fully in line with the national concept of green and sustainable development.

▲The construction workers put the "building blocks" in the corresponding positions

"The double skin wall panels, laminated top panels, laminated bottom panels and other components, as well as aluminum formwork and other materials used in this project. All production links are prefabricated and processed in our park company, which reduces the on-site labor intensity and greatly improves environmental protection and energy consumption. " The "park company" mentioned by Zhang Jianguo, deputy general manager of the Construction Division, is the Shanxi Construction Industry Modernization (Jinzhong) Park. The park is located in Jinzhong Development Zone, a demonstration area for transformation and comprehensive reform in Shanxi, with a total planned land area of 3,000 mu.

"The prefabricated building method has a vivid metaphor like 'building blocks'." Zhang Jianguo introduced that compared with the traditional construction method, the prefabricated building focuses on "prefabrication" and "assembly". "Our park is a production base for the entire industrial chain of prefabricated buildings, and all required components and accessories can be produced here. Then, the prefabricated components and accessories are sent to the construction site, and they can be assembled and fixed like 'building blocks'. "

▲The prefabricated flood control box culvert project is the first in Shanxi Province

In recent years, prefabricated buildings have been applied in more and more places in Shanxi Province. Last year, the province's newly started prefabricated buildings reached 7.76 million square meters, accounting for 23.26% of the new construction area, successfully completing the annual target tasks. This year, Shanxi Province will actively promote the implementation of prefabricated construction projects, steadily promote the construction of prefabricated concrete buildings, and at the same time strengthen the quality and safety supervision of prefabricated construction projects under construction, and explore methods such as layered acceptance and sub-item acceptance. While ensuring construction quality, improve construction efficiency.

An Jianliang, deputy general manager of Shanxi Jiantou Construction Industry Co., Ltd., said that prefabricated buildings are an important direction for the transformation and upgrading of the construction industry, and are of great significance to promoting the development of green buildings. In the future, it will continue to plan and develop new formats, new technologies and new products for prefabricated buildings, and contribute to the realization of the "dual carbon" goal and high-quality development of Shanxi Province.
