Fabricated subway station and construction method thereof

Abstract

The invention discloses a fabricated subway station and a construction method thereof. The fabricated subway station comprises continuous walls, steel pipe columns, top beams, waist beams, middle prefabricated supports, top supports, a bottom plate, middle prefabricated slabs and top prefabricated slabs, wherein the steel pipe columns are arranged between the opposite continuous walls, the top beams are arranged on the tops of the continuous walls, the waist beams are arranged on the opposite side walls of the continuous walls, the middle prefabricated supports are spliced between the two waist beams in a grid shape, the top supports are arranged between the two opposite top beams in a grid mode, the middle prefabricated slabs are spliced in the middle prefabricated supports which are located in grids, and a plurality of top prefabricated slabs are spliced in the top supports which are located in the grids. The construction method comprises the steps of steel pipe column construction, top-layer foundation pit construction, middle-bottom-layer foundation pit construction, middle prefabricated support installation, bottom plate and waterproof construction, middle prefabricated slab assembly, top prefabricated slab assembly and laminated layer cast-in-place, internal structure assembly and top waterproof construction. The fabricated subway station has the effects that the construction period of the subway station is shortened, and the construction process is energy-saving and environment-friendly.

Description

technical field [0001] The invention relates to the field of underground building construction, in particular to an assembled subway station and a construction method thereof. Background technique [0002] At present, with the continuous development of the country's transportation, the country is further promoting the strategy of comprehensive pipe corridors and sponge cities. my country's large and medium-sized cities will surely set off a new round of climax in underground engineering construction, among which subway construction has become an important part of urban construction. [0003] Existing, during the construction process of the subway station, support structures such as diaphragm walls, crown beams and waist beams are used only as temporary structures during the construction process of each floor. After the construction in the subway station is completed, the diaphragm walls , Crown beams and waist beams and other supporting structures are removed. [0004] In v...

AI Technical Summary

Problems solved by technology

[0004] In view of the related technologies mentioned above, the inventor believes that there are defects such as adopting continuous walls, crown beams, waist beams and other support structures as temporary structures, which have long construction period, large resource consumption and relatively large pollution to the environment
