Fabricated subway station and construction method thereof

Abstract

The invention provides a fabricated subway station and a construction method thereof, and relates to the field of subway stations. The fabricated subway station comprises a plurality of components, wherein the plurality of components are annularly combined, the plurality of components include a bottom plate component, a bottom corner component, a side wall component, a middle plate component, a top corner component and a top plate component, concave-convex structures which are matched with one another are respectively arranged at the edges of the components, and the butt joint positions of every two adjacent components are filled with sealing structures; and embedded grooves which extend in a longitudinal direction are further formed in the edges of the components, the embedded grooves ofevery two adjacent components are oppositely formed, and connecting pieces which are used for forming opposite fastening force on every two adjacent components are installed in the embedded grooves. The opposite fastening force is formed on every two adjacent components through the connecting pieces, so that the sealing structures in the butt joint positions have good sealing effects; and a plurality of bolt structures are replaced by the complete connecting pieces, so that the bending moment is large, the force transmission is uniform, firm fastening force can be formed on every two adjacentcomponents, the high-performance waterproof requirement is met, the operation is simplified, and the construction efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of subway stations, in particular to an assembled subway station and a construction method thereof. Background technique [0002] At present, subway stations usually adopt the construction method of on-site pouring, which mainly includes steps such as building formwork, binding steel bars, pouring concrete, solidifying and removing formwork. However, there are many problems in on-site pouring, such as heavy labor, poor on-site operating conditions, great impact on the surrounding environment, and long construction period. [0003] Based on the above problems, the technology of prefabricated subway stations was subsequently developed. For example, the Chinese invention patent application with the application publication number of CN107761765A and the application publication date of 2018.03.06 discloses a double-column main structure of a fully assembled subway station and its construction method , and specif...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the above problems, the purpose of the present invention is to provide a prefabricated subway station and its construction method, so as to solve the problem that the existing components can bear small bending moment when bolted connection cannot meet the design requirements, and the bolted connection force transmission is uneven , it is easy to cause structural stress concentration and cause structural damage, which cannot meet the high-performance waterproof requirements; moreover, the operation of screwing the bolts is cumbersome and the construction efficiency is low
