The main structure of the main structure of Anqing Road Station in Changchun Rail Transit Line 7 is completed

On September 4th, with the last bolt fastener, the first phase of the two -phase project of the Changchun City Rail Transit Line 7 of the China Railway Construction Bridge Company, the first phase of the project secondary project, the prefabricated main structure of Anqing Road Station was smoothly assembled It marks the successful completion of the project node of the project, laying a solid foundation for the subsequent construction and production of the project department.

Anqing Road Station is located at the intersection of Xingshun Road and Dongfeng Street. It is the second -floor island -style station on the underground. The total length is 198.7 meters. It is equipped with a assembly station under the pile anchor system. The assembly component has a total of 504 yuan and a total of 106,000 tons of assembly. "The heaviest top board component is more than 10.5 meters and weighs 55 tons. In order to ensure the quality of the subway structure, prefabricated stations have high requirements for prefabrication and assembly accuracy of components." According to Sui Xiulong, the deputy manager of the project, Anqing Road Station successfully overcome subway construction Small venues, high underground structure waterproof requirements, and synchronous operation of paddling and assembly have accumulated valuable experience for the construction of the small field assembly stations.

During the construction process of prefabricated stations, in order to ensure the safety and quality of the construction section, the project department made a practical safety and quality management method, prepared a special construction plan for lifting, and strictly controlled the lifting in accordance with the requirements during the lifting and assembly process. The lifting equipment is maintained, and the equipment is strictly prohibited from the operation of the equipment. At the same time, the construction of the construction staff's education and technical base is strictly implemented, and the lifting procedures are strictly implemented to comprehensively ensure the safe, high -quality and efficient advancement of prefabricated construction.

Huo Chengying, the chief engineer of the project, introduced that compared with traditional craftsmanship, prefabricated stations have the advantages of fast construction, high labor productivity, small climatic constraints, high labor productivity, excellent engineering quality, small construction land, and energy conservation and environmental protection.
