A construction method for anti-leakage construction of basement post-pouring belt

Abstract

The invention relates to the field of building construction, in particular to an anti-leakage construction method for a post-cast strip of a basement. The anti-leakage construction method for the post-cast strip of the basement includes the steps of step 1, installing outer wall steel bars and an outer wall formwork part of the basement, and constructing a fast-easy setback grid; step 2, preparingwater stop plates of the basement; step 3, arranging waterproof coatings on the outer walls and the water stop plates of the basement; step 4, installing the water stop plates on the outer walls anda bottom plate of the post-cast strip of the basement, and binding or welding steel bars embedded in the water stop plates and the outer wall steel bars of the basement; step 5, filling the gaps of the installed water stop plates with a filler for filling and leveling up treatment; step 6, coating the surfaces of the water stop plates with waterproof mortar, and manufacturing inner corner parts into an arc angle shape; and 7, carrying out integral waterproof construction on the outer walls of the basement, repairing the gaps, arranging protective layers on the outer sides of the waterproof coatings, then carrying out backfilling, and completing anti-leakage construction of the post-cast strip of the basement.

Description

technical field [0001] The invention relates to the field of building construction, in particular to an anti-leakage construction method for basement post-cast belts. Background technique [0002] In order to prevent harmful cracks in the cast-in-place reinforced concrete structure due to uneven shrinkage or uneven settlement during construction, according to the requirements of the design or construction specifications, it is necessary to leave post-cast strips at the corresponding positions of the basement floor and exterior walls. However, during construction in some cities, due to the extremely rich local groundwater resources, when the foundation pit is super deep (more than 10m), the groundwater pressure will be greater, and the existing post-pouring belt structure makes rainwater, groundwater, sediment and sand around the foundation pit Garbage etc. are easy to enter the main body of the foundation from the deformation joints of the outer wall, and gather in the post-...

Problems solved by technology

However, during construction in some cities, due to the extremely rich local groundwater resources, when the foundation pit is super deep (more than 10m), the groundwater pressure is greater, and the existing post-pouring belt structure makes rainwater, groundwater, sediment and sand around the foundation pit Garbage etc. are easy to enter the main body of the foundation from the deformation joints of the outer wall, and gather in the post-casting belt of the bottom plate, which is difficult to discharge and clean up. It is easy to cause the steel bars and water-stop steel plates in the structure to be soaked in water and rust, which affects the pouring quality of the post-casting belt , after the construction of the post-pouring belt on the exterior wall, it is also prone to cracking and water leakage, which increases the construction cost and delays the construction period
