Waterproof and drainage structure and construction method for back surface of basement

Abstract

The invention discloses a waterproof and drainage structure and a construction method for the back surface of a basement, relating to the technical field of building waterproofing, comprising: one or two bent perforated plates; a plurality of seepage holes, which are arranged through the facade of the bent perforated plates Above: the cover plate is set on the upper side of the bent perforated plate, and a water-swellable waterproof adhesive layer is arranged between the cover plate and the bent perforated plate; the waterproof and drainage structure can effectively solve the wet stains on the back surface of the basement , seepage and other leakage problems, avoid the basement from falling into the vicious cycle of "repair every year, leak every year", and greatly reduce the frequency and cost of basement leakage maintenance.

Description

technical field [0001] The invention belongs to the technical field of underground building waterproofing, and more specifically relates to a waterproof and drainage structure and a construction method for the back surface of a basement. Background technique [0002] With the decrease of urban construction land and the continuous development of the construction industry, people use the underground space more and more widely, and the types and quantities of the basements of construction projects are also increasing. Leakage in the basement floor. Once a leak occurs in the basement, it is very difficult to find the leak point. It is difficult to cure the symptoms and not the root cause in partial repairs. The overall repair is a large project, high cost, and long cycle; and when the structure is in an unstable state, the existing technology can It is difficult to guarantee the quality of its maintenance and construction; if left alone, it will seriously affect the use of the ...
