Description

Basement waterproof structure in high water level area

Technical Field

The utility model relates to a basement waterproof structure in a high water level area, and belongs to the technical field of building waterproofing.

Background

The basement outer wall waterproof engineering is an important component of the building engineering. For a long time, due to the complexity and the lack of comprehensive knowledge of the waterproof engineering of the basement outer wall or the old limit of economic factors and design ideas, the leakage phenomenon of the basement outer wall engineering is endlessly developed. Particularly, when coming in rainy seasons, many households find that the north outer wall and the east and west outer walls of the basement often have quality problems of penetrating water. The indoor white wall body is blackened, so that materials are damped, even rotten, deteriorated or invalid, and the safety of the building is directly affected and the use function is reduced by serious people. From the perspective of water resistance of the whole building, the water permeability of the outer wall of the building is higher than that of a roof at present, and the water resistance damage repair difficulty of the outer wall is high and the quality is unstable. Many industry personnel propose an approach to waterproof the exterior wall, but although improvements are made, it is difficult to fundamentally solve the problem of leakage of the exterior wall of the basement.

At present, the common practice of waterproof of the basement exterior wall is to externally paste waterproof coiled materials and self-waterproof concrete. However, many engineering cases prove that the waterproof effect is not ideal. The leakage causes not only the considered factors in construction, but also the constraint of the waterproof thought. Basement wall and bottom plate are located groundwater environment for a long time, and are higher to waterproof quality requirement, and tiny crack will cause slight infiltration water, and infiltration water can't discharge and will lead to the groundwater pressure direct action of UNICOM on building structure, causes the hidden danger to building safety.
