Qilu Network Lightning News October 29 news On October 29, with the slow fall of 113 tons of bottom plate components, the prefabricated assembly subway station undertaken by the Fourth Bureau of China Railway - Qingdao Metro Line 6 Keluoshi Station officially started the assembly construction, marking that the main structure of the station was pressed the "acceleration key".
"Qingdao Metro Line 6 Koloshi Station is the first fully prefabricated prefabricated subway station in China, that is, the main body of the station is all prefabricated assembled, each ring is 2 meters, a total of 8 components are assembled, a total of 64 rings, a total of 22720 tons." Wang Development, chief engineer of the project, said. "The construction of the prefabricated structure of The Kloshi Station mainly uses the separation trolley in the gantry crane and pit for assembly operation. The bottom plate and side wall are hoisted and placed through the door crane, and the top device of the trolley is fine-tuned in place; the top plate and the middle plate are mainly hoisted to the trolley through the door crane, and the trolley is used to adjust the position of the prefabricated components, the fine adjustment of the top plate, the displacement of the middle plate, etc., to carry out the assembly operation. "Prefabricated assembly technology is an important means to achieve low-carbon construction.
The "13th Five-Year Plan" Prefabricated Building Action Plan issued by the Ministry of Housing and Urban-Rural Development clearly points out that the development of prefabricated buildings is the need to implement the concept of green development, and it is the need to promote the deep integration of the construction industry and informatization, industrialization, supply-side reform, cultivate new industries, new kinetic energy, and realize the modernization of the construction industry. Prefabricated subway station is the latest form of prefabricated building, is the traditional construction of steel reinforcement, concrete concentrated in the factory flow production, components of finished products stored in the factory area, according to the construction and production needs of the transported to the site, component assembly is like building blocks, the prefabricated main structure on the foundation piece by piece in order of splicing molding, so that the construction and production of the building structure to achieve factory.
Compared with the traditional construction method, the prefabricated station has the advantages of fast construction speed, small climatic constraints, high labor productivity, excellent project quality, less construction land, energy saving and environmental protection. The technology is not affected by the winter construction environment, can reduce the traffic interference on urban roads, than the cut-and-shoot smooth practice can shorten the construction period of 4-6 months, greatly reduce the on-site construction personnel, reduce the impact of construction on the urban environment, so as to reduce noise, dust, green, information construction.
