AI Technical Summary

Technical Problem

The water leakage problem of underground pipe corridor gaps has affected the structural safety and functional operation. The existing treatment methods are not professional and targeted enough, making it difficult to effectively solve the water leakage problem between the gap between the wall casing and the pipeline and the outside of the wall casing.

Method used

A underground pipe corridor gap maintenance process is designed, including groove removal, grouting, filling water stop glue strips, sealing and on-site cleaning. By using appropriate tools and materials, the gap is fully filled and sealed, forming a second waterproof barrier.

Benefits of technology

It significantly improves the waterproof performance of the entire system, prevents moisture from penetrating into the interior of the underground pipe corridor, extends the duration of the waterproof effect, reduces maintenance frequency and cost, and improves construction efficiency and safety.

Abstract

The invention relates to the technical field of underground pipe gallery gap maintenance, in particular to an underground pipe gallery gap maintenance technology which comprises the steps of groove removing, grouting, water stop rubber strip filling, blocking, field cleaning and the like, comprehensive sealing can be achieved by specifically repairing a gap between a wall bushing and a pipeline and the problem of water leakage on the outer side, and the service life of the wall bushing is prolonged. The waterproof performance of the whole system is remarkably improved, water is prevented from permeating into the underground pipe gallery, gaps can be effectively filled and reinforced through the technology, secondary leakage caused by material aging or structural change is prevented, and the duration time of the waterproof effect is prolonged.
