Construction method for basement cast-in-situ outer wall seepage prevention

Abstract

The invention relates to the technical field of building engineering, in particular to a construction method for basement cast-in-situ outer wall seepage prevention. The construction method has the following technical scheme key point that after an early-stage preparation is made, the surface of a basement is processed, and an indication line is marked on the surface of the basement; the dry and clean surface of the basement is evenly coated with glue; then, an additional layer is firstly independently made on positions, including inside and outside corners and the like; then, along the indication line, a large area of coiled materials coated with binding agents is laid, and the coiled materials are rolled; polyurethane sealants are painted to process a lap joint part of the coiled materials; and finally, after a polyethylene foam plastic plate is externally laminated, soil is backfilled. According to the construction method for the basement cast-in-situ outer wall seepage prevention,the waterproof performance of the coiled materials is used for providing seepage protection for an outer wall, and while the durability of the outer wall structure prevents from being affected, the outer wall has a good seepage prevention effect.

Description

Technical field [0001] The invention relates to the technical field of construction engineering, in particular to a construction method for anti-seepage of cast-in-place exterior walls of basements. Background technique [0002] A basement is a room under the outdoor ground in a building. Building a basement below the ground floor of the house can improve the efficiency of building land. Some high-rise buildings have a very deep foundation. Making full use of this depth to build a basement will have both economic and use effects. good. [0003] However, the leakage phenomenon of the basement exterior wall engineering is endless. It is expected that when the rainy season comes, the exterior wall of the basement often leaks, causing the indoor white wall to become black, causing the materials to be damp and even decayed. In severe cases, it will directly affect the building. The safety of objects and reduced use function. From the perspective of the waterproofing of the entire buil...

Problems solved by technology

However, many engineering cases have proved that compared with ordinary concrete, due to the combination of materials and admixtures, the durability of self-waterproof concrete after hardening is very limited, especially in cold climates. In addition, self-waterproof concrete Unstable bubbles are also prone to appear in the medium, and the drying shrinkage is slightly larger
