AI Technical Summary

Technical Problem

The prior art is difficult to quickly and conveniently detect the sealing of the joints of the integrated pipe corridor, especially in the prefabricated integrated pipe corridor, which cannot effectively detect leakage at the joints.

Method used

A comprehensive pipe corridor joint seal detection method is adopted, including prefabricated elastic sealing gasket, pasting polymer waterproof coils and waterproof strips, recording of thermal images at the joints through infrared thermal imagers, and filling water through the slot grooves, comparing the thermal images before and after water injection, and analyzing the parts with obvious temperature differences to determine whether the joints are tight.

Benefits of technology

It realizes rapid and convenient inspection of the sealing of the integrated pipe corridor joints, can effectively determine whether the joints are tight, and improves the accuracy and efficiency of inspection.

Abstract

The present invention relates to the technical field of pipeline gallery sealing detection, in particular to a method for detecting the sealing of the joints of a comprehensive pipeline gallery; comprising the following steps, step S101: prefabricating elastic sealing pads; step S102: pasting polymer waterproof coiled materials; step S103: pasting waterproof pressure strips; step S104: thermal image recording; step S105: water injection into the caulking groove; step S106: thermal image recording after water injection; step S107: thermal image comparison before and after water injection. After adopting the above method, the present invention records and stores the thermal images of the joints by taking pictures of the internal infrared thermal imager before and after water injection in a data analysis system, compares the thermal images of the same part before and after, analyzes the parts with significantly larger temperature differences, and further determines whether the joints are tight.
