Water blocking process of building through-wall pipeline

Abstract

The invention relates to the technical field of pipeline water blocking processes, and discloses a water blocking process of a building through-wall pipeline. The process comprises the following stepsof 1, cleaning the surface of a through-wall position of the pipeline, then wiping off water spots left by surface cleaning, meanwhile, cleaning the interior of a hole of a wall, and removing other impurity particles such as dust in the hole, so as to guarantee the solidification effect of glue during follow-up construction; and 2, sleeving the outer ring on one side of the through-wall positionof the pipeline with a sealing rubber ring. According to the process, rubber strips are plugged and fixed between the pipeline and the hole, meanwhile, the rubber strips are evenly distributed on theouter ring of the pipeline and supported in the hole, then gaps among the rubber strips, the pipeline and the hole are filled with a sealant, the sealant can be tightly attached to the pipeline and the hole through the rubber strips, and evenly fills the hole, meanwhile, part of the sealant is saved, the water blocking effect is good, water leakage can be avoided for a long time, and the water blocking action is achieved.

Description

technical field [0001] The invention relates to the technical field of pipeline water blocking technology, in particular to a water blocking technology of pipelines passing through walls of buildings. Background technique [0002] At present, in the construction field, in the construction of various pipelines passing through buildings and various pipeline cells, the pipelines are passed through the sleeves in the reserved walls. In the design and construction, the mechanical and electrical pipelines, fuel, oil, gas, water , lightning protection grounding body and other pipelines sometimes need to penetrate the wall to connect or lead out, and it is inevitable to penetrate the outsourcing waterproof board on the water-facing surface of the wall. Therefore, the place where the outsourcing waterproof board is penetrated by the pipeline becomes the waterproof weak position of the wall and the fully outsourcing flexible waterproof system. [0003] The traditional water blocking ...

AI Technical Summary

Problems solved by technology

[0003] The traditional water blocking process puts foam glue between the holes where the pipeline passes through the wall. Because the sealing effect of foam glue is average, there is also a sealant with better sealing effect. However, whether it is foam glue or sealant, during construction, The gap between the pipeline and the hole is difficult to fill. In addition, it will waste materials when filling. At the same time, it will cause the sealant to accumulate between the bottom of the pipeline and the hole, so that the water blocking effect is average, and water leakage is prone to occur later.
