Basement waterproof roll construction method and waterproof structure

Abstract

The invention discloses a basement waterproof roll construction method and a waterproof structure, and relates to the technical field of protection of building foundation structures. According to thetechnical scheme, the basement waterproof roll construction structure is characterized by comprising a cushion layer, wherein a pressure reduction layer, a base layer and a waterproof roll layer are arranged on the upper side of the cushion layer from bottom to top; the pressure reduction layer is of a double-layer hollow structure; a plurality of water permeable holes are formed in the bottom ofthe pressure reduction layer; balance valve assemblies which move in the vertical direction along with water pressure through buoyancy components and then communicate with the different holes are arranged in the water permeable holes, and thus underground water flows into the pressure reduction layer when the static water pressure of a basement is beyond than the pressure of the balance valve assemblies; when the pressure of the pressure reduction layer is beyond than the static water pressure, the water in the pressure reduction layer is drained into the cushion layer, and thus pressure self-balancing is completed; and the base layer and the waterproof roll layer form a secondary waterproof structure, and thus waterproofing of the basement is reinforced. The basement waterproof roll construction method and the waterproof structure have the technical effects that storage and replenishment are conducted through the pressure reduction layer according to the static water pressure of the underground, and thus static water balance of the whole basement is balanced.

Description

technical field [0001] The invention relates to the technical field of protection of building basic structures, in particular to a basement waterproof coiled material construction method and a waterproof structure. Background technique [0002] Building leakage is a prominent quality defect at present, and it is also the most intense problem reported by users. Leakage in buildings mostly occurs in basements, roofs, toilets and bathrooms. Basement waterproofing project, because it is a concealed project, and the underground conditions are relatively complex, so basement water leakage is the most difficult problem to solve in waterproofing projects. The main causes of water seepage in the basement are the quality of the concrete, cracking of the concrete, and the quality of flexible waterproofing. Concrete is a porous material. In order to meet the waterproof requirements, the density of concrete should be increased to minimize concrete cracking. When choosing flexible wate...

Problems solved by technology

[0004] Because the underground engineering is in the underground environment, it bears the immersion of groundwater and is subjected to the force of underground static water pressure for a long time. The existing "drainage"-based active drainage, decompression and anti-floating method, the core of this method is to reduce the design water level by drainage. The water load acts on the structural floor, but the drainage and decompression will affect the surrounding environment, thereby affecting the structural stabi
