Anti-leakage treatment method and anti-leakage device at conjunction of pipeline and well wall

Abstract

The invention relates to an anti-leakage treatment method at the conjunction of a pipeline and a well wall, which comprises the following steps: well mounting the pipeline on the well wall, and firstly using asphalt to carry out crack pouring treatment on a mounting crack between the pipeline and the well wall to lead the mounting crack to be filled with the asphalt; then brush-coating the asphalt at the conjunction of the pipeline and the well wall, and leading the pipeline, the well wall, an asphalt crack pouring layer filled in the mounting crack and an asphalt smear layer brush-coated at the conjunction of the pipeline and the well wall to be connected into a whole; and finally using waterproof mortar to carry out mortar finishing treatment on the periphery of the conjunction of the pipeline and the well wall. The invention further provides an anti-leakage device which comprises the asphalt crack pouring layer filled in the mounting crack between the well wall and the pipeline, the asphalt smear layer smeared on the periphery of the conjunction of the pipeline and the well wall and a mortar finishing layer smeared and covered outside the asphalt smear layer. The method and thedevice can greatly reduce the leakage phenomenon at the conjunction of the pipeline and the well wall, effectively reduce the rework phenomenon at the conjunction, improve the construction efficiencyand reduce the construction cost.

Description

technical field [0001] The invention relates to an anti-leakage treatment method and an anti-leakage device for the connection between a pipeline and a well wall. Background technique [0002] Most of the places are pipe joints and the joints between pipes and inspection wells. Most of the pipes used today are electric hot-melt joints. The probability is large, so it often makes it difficult to pass the closed water test. In the closed water test, once leakage occurs at the connection between the pipeline and the inspection well, the connection between the pipeline and the inspection well must be removed for re-construction. The rework cost is high and the construction time is long, especially for large-diameter pipelines and inspection wells. High, greatly increasing the construction cost. [0003] How to ensure the tightness of the connection between the pipeline and the inspection well and ensure that the closed water test is passed at one time is of great significance...

AI Technical Summary

Problems solved by technology

[0004] The traditional connection method between the pipeline and the inspection well is as follows: first build the inspection well to the elevation of the inner bottom of the pipeline, then install the pipeline, and then build a brick arch on the upper part of the pipeline after the installation is completed, and then build the inspection well to the design elevation. The gaps at the joints of the inspection wells are filled with ordinary mortar, and ordinary mortar is applied inside and outside the inspection wells. After this treatment, the tightness is difficult to guarantee, and leakage is prone to occur, resulting in rework

If seepage occurs at the connection between the pipeline and the inspection well, it will take 2 workers 2 hours to dismantle an inspection well, and 3 workers 5 hours to build another inspection well after the connection is completed. The cost of rework is high, and the construction time is long. increased construction costs
