Waterproof and drainage construction method for large area basement top plate

Abstract

The invention discloses a waterproof and drainage construction method for a large area basement top plate. According to the area of the basement top plate and the range of buildings on the ground, thelarge area is reasonably divided into a plurality of continuous and regular square area units, the edge position of the basement top plate or the position where the basement top plate meets the buildings on the ground is divided into corner area units which are partly automatically formed on the periphery, waterproof and drainage structures are arranged around each area unit and within each areaunit, so that the waterproof and drainage structures in the area units communicate with the waterproof and drainage structures around the area units, adjacent area units communicate with each other through the surrounding waterproof and drainage structures, and the square area units adjacent to the waterproof and drainage structures around the corner area units communicate with each other and communicates with an open drainage ditch of a rainwater pipe network of a housing estate. During the construction of a construction layer of the waterproof and drainage structures of the basement top plate, the construction of the area units corresponding to the range of the completed basement top plate is carried out, and the construction of the waterproof and drainage structures is performed first on which one comes out first.

Description

technical field

[0001] The invention belongs to the field of basement roof waterproofing and drainage construction, in particular to a large-area basement roof waterproofing and drainage construction method. Background technique

[0002] For the basement roof, waterproof and drainage is the key point. There are two main methods of waterproofing and drainage of the traditional basement roof:

[0003] One is to make open ditches on the building layer, and in order to ensure the appearance, the distance between the open ditches is relatively large. The building layer is 0.5% slope towards the drainage ditch, and 0.5% slope inside the drainage ditch. This approach often has an unsatisfactory drainage effect on large-area basement roofs. Because the large-area basement roof has a large area and a long slope, it is difficult to make every part of the large-area roof meet the slope requirements of the design, and it is easy to have poor drainage in some places, and finally cause ...
