A skin-type waterproof structure of a subway station and its construction method

Abstract

A skin-type waterproof structure of a subway station and a construction method thereof, comprising an outsourcing waterproof layer arranged outside the main structure of the constructed subway station, the main structure of the constructed subway station includes a bottom plate, a side wall, a top plate and a middle plate; the bottom plate, side walls, Both the middle plate and the top plate are reinforced concrete structures poured with waterproof concrete; the outsourcing waterproof layer includes the top plate waterproof layer arranged above the top plate, the bottom plate waterproof layer arranged under the bottom plate and the side wall waterproof layer arranged outside the side wall; Compared with the prior art, the construction technology of the present invention is simple in construction and high in efficiency, and it is convenient to deal with weak waterproof details such as wall pipes and water outlets of subway stations, and two types of waterproof materials together constitute multiple lines of defense, which are compatible with the stations. The main body of the structure has high bonding strength, prevents water channeling, and has no joints as a whole, which can form a "skin-like" waterproof to ensure the waterproof effectiveness of subway stations.

Description

Technical field [0001] The invention belongs to the technical field of subway station waterproof construction, and in particular relates to a subway station skin type waterproof structure and a construction method thereof. Background technique [0002] The subway is an increasingly important means of transportation in social production and people's lives. It is one of the important means to solve urban problems such as the continuous expansion of the scale of the city and the continuous growth of the population. However, there are still many problems that have not been well resolved during the construction of a large number of underground projects, among which the leakage of subway stations is one of them. Groundwater, especially corrosive 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 corrodes the steel bars inside the structure, which directly le...

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
