Problems solved by technology

The past construction experience is to leave a sunken groove at the post-pouring belt, but the construction effect is not ideal
The consequences are that the garbage in the post-pouring belt is not cleaned up, or because of the influence of underground water pressure, water seepage occurs in the construction joints at the post-pouring belt, resulting in secondary repairs

Abstract

The invention provides a construction method of a hydrophobic structure of a post-cast strip of a bottom plate of a basement. The construction method comprises the following steps of (1) positioning and putting a sample; (2) carrying out groove earth excavation; (3) carrying out cushion layer construction; (4) building a trench wall and a draining well; (5) manufacturing and burying a rigid polyvinyl chloride (UPVC) pipe; (6) filling and laying gravels; (7) surfacing cement mortar; (8) constructing a basic cushion layer. The construction method has the advantages of being simple in construction, improving the quality, protecting the environment and the like, and is convenient for construction of the post-cast strip.

Description

technical field [0001] The invention relates to a construction method, in particular to a construction method for a basement floor post-pouring belt hydrophobic structure. Background technique [0002] With the development of the construction industry, there are more and more super-long and super-deep basement structures and the connection between the high-rise main building and the skirt building. In the form of pouring belt, temporary construction joints are left in the cast-in-place reinforced concrete structure. Since the concrete pouring of the post-casting belt can generally be carried out after the main structure of the project is completed, it is inevitable to cause long-term water accumulation at the post-casting belt of the basement floor Pouring dirt has brought difficulties in construction technology and hidden dangers to construction quality for the construction of the post-pouring belt, especially in the soil layer with a high groundwater level and larg...
