Bottom plate waterproof node for underground pipe gallery

Abstract

The invention provides a bottom plate waterproof node for an underground pipe gallery. The bottom plate waterproof node comprises a concrete protection layer arranged at the bottom edges of the bottomplate, a bottom plate waterproof layer, a cushion layer, and a side wall waterproof layer arranged outside side walls; the bottom plate waterproof layer is arranged between the concrete protection layer and the cushion layer, and is upwards folded in the side edge direction of the bottom plate to reach a construction joint; and a lower brick wall protection layer is arranged on the outer side ofpart, at the side edges of the bottom plate, of the bottom plate waterproof layer, and an upper brick wall protection layer is arranged on the outer side of the side wall waterproof layer. According to the bottom plate waterproof node, the whole seamless connection is realized, the bottom plate waterproof node is wrapped around a structure layer as the skin so that the structure layer can be better protected, true skin type waterproof effect is achieved, and the problem that the waterproof layer is pulled and cracked caused by the fact that the cushion layer settles and is damaged is solved, so that the waterproof term is prolonged, and the possibility of water mixing and water leakage is reduced.

Description

technical field [0001] The invention relates to the technical field of building waterproofing, in particular to a floor waterproofing node for an underground utility gallery. Background technique [0002] The waterproof project of the underground comprehensive pipe gallery is to put an impermeable coat on the exterior of the reinforced concrete structure to ensure the safety of the pipe gallery building structure and at the same time ensure that all pipelines can run in a watertight environment. The waterproof of the pipe gallery is important. Sex speaks for itself. In order to ensure the reliability of the waterproofing of the pipe gallery, it is necessary to consider two aspects of structural waterproofing and material waterproofing. [0003] In addition to structural waterproofing measures for civil structures such as structural deformation joints, construction joints, wall-penetrating pipes, and sumps, adding reliable waterproof materials to the outside of the structu...

AI Technical Summary

Problems solved by technology

[0007] 1. The material of the waterproof membrane itself cannot be closely attached to the concrete, and the impact or protrusion on the concrete surface during installation will easily puncture the waterproof board, resulting in water leakage;

[0008] 2. The joint between the board and the board is the weak link of the pipe gallery. If there is a slight crack inadvertently, the entire waterproof system will fail;

[0009] 3. Concave-convex parts are prone to appear on the concrete wall, or even larger cavities. Extrusion and peripheral deformation will cause the waterproof board to stretch, especially the joint parts are prone to fracture and damage
