A special waterproof structure for through-wall pipes and its construction method

Abstract

The invention relates to a special waterproof structure for wall-penetrating pipelines and a construction method thereof. The structure includes: a waterproof layer in the pipeline area, which wraps the outer wall of the pipeline in an entire circumference, and has inner folds that protrude radially and surround the pipeline; the wall area Inner waterproof layer, which is lap-bonded with the end of the waterproof layer in the pipe area, and fixed on the surface of the wall; outer waterproof layer in the pipe area, which wraps the outer wall of the pipe and completely covers the waterproof layer in the pipe area At the same time, there are outer folds stacked on the inner folds; the outer waterproof layer of the wall area is lap-bonded with the end of the outer waterproof layer near the wall of the pipe area, and is fixedly laid on the surface of the wall body and completely covers the wall area The waterproof layer; the connector, which is used to sealingly fix the far wall end of the outer waterproof layer on the pipe, and make the far wall end of the waterproof inner layer be located between the connector and the wall. The structure not only has good waterproof performance, but also is not easy to rupture when the pipeline is heated and expanded, which improves the operation safety of the urban comprehensive utility gallery.

Description

technical field [0001] The invention relates to the technical field of pipeline laying, in particular to a special waterproof structure for pipelines through walls and a construction method thereof. Background technique [0002] The urban comprehensive pipe gallery has integrated various engineering pipelines such as electric power, communication, gas, heating, water supply and drainage, among which heat pipes, gas pipes and other pipes need to pass through the walls of the pipe gallery to make it flow from one pipe to the other. The corridor enters another pipe gallery, but in order to ensure the safe operation of the urban comprehensive pipe gallery, the gap between the pipe and the wall needs to be sealed and waterproofed. [0003] The traditional special waterproof structure for through-wall pipelines is difficult to meet the waterproof requirements. The main reason is that the thermal pipeline will undergo thermal displacement during the heating period. In severe cases...

[0003] The traditional special waterproof structure for through-wall pipelines is difficult to meet the waterproof requirements. The main reason is that the thermal pipeline will undergo thermal displacement during the heating period. Water leakage accidents will affect the power supply and communication in the pipe gallery in serious cases
