Abstract

The application discloses a basement waterproof foundation pit structure and a construction method, which relate to the technical field of building construction. The technical solution is a basement waterproof foundation pit structure, including a basement main body. The bottom of the basement main body is provided with a waterproof bottom plate. The waterproof bottom plate includes a base layer made of ordinary concrete. A shallow layer formed by pouring, the side of the main body of the basement is provided with a waterproof side plate, the waterproof side plate includes a support layer made of ordinary concrete poured, and a waterproof layer covering the outside of the base of the side plate, the The waterproof layer is formed by pouring waterproof concrete, and the waterproof bottom plate is spliced ​​with the waterproof side plate. The application structure is reasonable, the consumption of waterproof concrete is reduced, and the cost is greatly reduced.

Description

technical field [0001] The application relates to the technical field of building construction, in particular to a basement waterproof foundation pit structure and a construction method. Background technique [0002] The foundation pit is an earth pit excavated at the foundation design position according to the base elevation and foundation plane size. Before excavation, the excavation plan should be determined according to the geological and hydrological data, combined with the conditions of the buildings near the site, and the waterproof and drainage work should be done well. When the foundation pit is excavated, because the groundwater level is higher than the excavation bottom, the groundwater will continue to infiltrate into the pit. In order to ensure that the foundation pit can be constructed under dry conditions, and to prevent slope instability, foundation quicksand, pit bottom uplift, pit bottom piping and The bearing capacity of the foundation is reduced, and the ...
