Underground waterproof engineering construction method

Abstract

The invention relates to an underground waterproof engineering construction method, and relates to the field of building construction. The method comprises the following steps of S1, prefabricating a foundation: laying waterproof coiled materials on the bottom surface and the side surface of the foundation; S2, prefabricating a wall body which comprises an inner wall, an outer wall and a stand column: laying waterproof coiled materials on one side of the inner wall and one side of the outer wall; S3, digging a foundation pit; S4, performing foundation construction: horizontally laying the foundation at the bottom of the foundation pit; S5, performing wall construction: installing the stand column on a cross beam firstly, then installing the inner wall on one side of the stand column, installing the outer wall on the other side of the stand column, enabling the waterproof coiled materials on the inner wall and the outer wall to face the side deviating from the stand column, and after construction of one wall body is completed, performing construction of the next wall; S6, performing water-stop belt construction: fixing water-stop belts to gaps between the foundation and the wall body and joints between the adjacent wall bodies; and S7, backfilling the foundation pit. The method has the effects that the site construction period is shortened, the construction environment is improved, and the construction process is more efficient and environmentally friendly.

Description

technical field [0001] The present application relates to the field of building construction, in particular to an underground waterproof engineering construction method. Background technique [0002] With the development of urban construction, urban ground space is insufficient, and the application of urban underground space becomes more and more important. For underground building construction, the primary requirement is to ensure the waterproof performance of underground building construction and prevent groundwater from entering the basement. [0003] The common underground building construction process includes the following steps: 1. First excavate the foundation pit, and build a retaining wall on the inner and outer rings of the foundation pit; Foundation construction; 3. After the foundation construction is completed, the wall construction is carried out above the foundation. When the wall construction is completed, the waterproof membrane is laid on the outside of t...

Problems solved by technology

[0004] The above-mentioned construction process requires on-site foundation and wall construction. The construction period is long and the construction site has a large amount of dust pollution, the construction environment is poor, and a large amount of construction waste is generated at the same time, which cannot meet the sustainable development of high efficiency, green and environmental protection. building construction requirements
