Subway station skin waterproof structure and construction method thereof

Abstract

The invention discloses a subway station skin waterproof structure and a construction method thereof. The subway station skin waterproof structure comprises an outer wrapping waterproof layer distributed on the outer side of a constructed subway station body structure; the constructed subway station body structure includes a baseplate, a side wall, a top plate and a middle plate; the baseplate, the side wall, the middle plate and the top plate are all reinforced concrete structures cast by waterproof concrete; and the outer wrapping waterproof layer includes a top plate waterproof layer distributed above the top plate, a baseplate waterproof layer distributed below the baseplate, and a side wall waterproof layer distributed on the outer side of the side wall. Compared with the prior art, the construction method is simple in construction, high in efficiency and convenient to treat such waterproof weak detail links as a wall penetrating pipe and a water falling port of a subway station; and multiple defense lines consist of two types of waterproof structures, so that the bonding strength with the station structure body is high, the water flowing is prevented, no joint is generated, the skin type water prevention can be formed, and the waterproof effectiveness of the subway station is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of waterproof construction of subway stations, and in particular relates to a skin-type waterproof structure of a subway station and a construction method thereof. Background technique [0002] The subway is an increasingly important means of transportation in social production and people's life, and it is one of the important means to solve urban problems such as the continuous expansion of the city and the continuous growth of the population. However, in the process of a large number of underground engineering constructions, there are still many problems that have not been well resolved, and the leakage of subway stations is one of them. Groundwater, especially erosive groundwater, has serious damage to the concrete structure itself. It not only chemically reacts with the concrete, resulting in a decrease in the strength of the concrete, but also erodes the steel bars inside the structure, directly leading...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a skin-type waterproof structure of a subway station and its construction method, to solve the technical problem that the waterproof layer does not fit the main structure in the prior art, and to solve the problem that the waterproof layer can creep and break in the prior art The technical problem of low elongation and easy to be damaged by corrosion also solves the technical problems of cumbersome construction, high cost and poor waterproof effect in the prior art
