Anti-leakage construction method for building underground outer wall out-of-wall group pipes

Abstract

The invention relates to the technical field of building construction, in particular to an anti-leakage construction method for building underground outer wall out-of-wall group pipes, which comprises the following steps: manufacturing expansion rubber waterproof rings according to the pipe diameters of the building underground outer wall out-of-wall group pipes, and sleeving each out-of-wall pipeline with the expansion rubber waterproof rings; a formwork is erected, and fine stone waterproof concrete is poured into the space defined by the formwork and the underground outer wall of the building; after the fine stone waterproof concrete reaches the designed strength, form removal is conducted, and a concrete pipe table is formed; the waterproof coiled material extends to the concrete pipe platform and is paved to form a waterproof layer; preparing a whole piece of waterproof coiled material and pasting the whole piece of waterproof coiled material on the front side end face of the concrete pipe platform; and waterproof sealant is embedded and filled at the pipe root position of the wall-out group pipe on the front side end surface of the concrete pipe platform. The expansion rubber waterproof rings and the waterproof concrete pipe tables are additionally arranged for all the out-of-wall pipelines in the out-of-wall group pipes of the underground outer wall of the building, so that pipe roots of original dense group pipes move forwards to the position with the second distance away from pipe openings in the outer sides of the out-of-wall group pipes, people can reach the pipe roots, and laying operation of waterproof coiled materials is facilitated.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to an anti-leakage construction method for group pipes of underground outer walls of buildings. Background technique [0002] The wall-outlet group pipes in construction projects are usually set up in groups of multiple pipes. The space between adjacent pipes is small and extends out of the underground outer wall of the building for a long distance, so that when the waterproofing membrane is constructed, the human hand cannot reach the wall-outlet group pipes. There is a risk of leakage at the connection between the pipe roots of the outgoing wall group pipes and the exterior wall of the building. SUMMARY OF THE INVENTION [0003] In view of the above problems, the embodiments of the present invention provide an anti-leakage construction method for group pipes of underground outer walls of buildings. [0004] An aspect of the implementation of the present invention ...

AI Technical Summary

Problems solved by technology

[0002] The group pipes out of the wall in construction projects are usually set up as a group of multiple pipes. The space between adjacent pipes is narrow and they protrude from the underground exterior wall of the building for a long distance. As a result, hands cannot reach into the group pipes out of the wall during waterproofing membrane construction. Waterproof membranes are pasted on the underground exterior walls of the buildings in between, which cannot form an overall continuous waterproof layer, and there is a risk of leakage at the connection between the pipe roots of the group of pipes out of the wall and the exterior wall of the building
