Repair method for inspection well and similar structures

Abstract

The invention discloses a method for repairing an inspection well and a similar structure. The method comprises the following steps that pipelines at the two ends of the inspection well to be repaired are blocked, water is pumped, the well wall is washed, and waste in the well is fished out; grouting leaking stoppage is conducted on broken portions of the inspection well to be repaired, corroded and powdered portions of the well wall are removed, and the broken portions and the removed portions are leveled; aeration-drying treatment is conducted on the interior of the inspection well to be repaired; the well wall in the area to be repaired is painted with hydrophilic primer and painted with photocuring sealing paint after being dried; after the photocuring sealing paint is solidified, a photocurable resin lining sheet is flatly attached to the surface layer of the photocuring sealing paint, and the photocurable resin lining sheet is solidified each time the photocurable resin lining sheet is attached by 1.2-1.5 m till the whole photocurable resin lining sheet is attached and solidified; and the junctions of the inspection well and the pipelines are smeared with waterproof glue. By the adoption of the method for repairing the inspection well and the similar structure, the repairing efficiency and the repairing quality can be well balanced, and the conflict between urban traffic pressure and urban road quality is resolved.

Description

technical field [0001] The invention relates to the field of municipal engineering, in particular to a method for repairing inspection wells and similar structures. Background technique [0002] The inspection well is set up for the maintenance of urban underground infrastructure such as power supply, water supply, drainage, sewage discharge, communication, cable TV, gas pipes, and street lamp lines, and is convenient for installation. It is generally installed at the intersection of pipelines, turning places, pipe diameter or slope changes, and at certain distances on straight pipe sections, which is convenient for regular inspection of ancillary structures. [0003] Inspection wells that have been used for a long time will have leakage, cracking, corrosion and other diseases, and necessary repairs are required. In the past, the repair of municipal inspection wells basically used large-scale renovation and repair, and the construction period was 5-7 days. In today's increa...

AI Technical Summary

Problems solved by technology

In the past, the repair of municipal inspection wells basically used large-scale renovation and repair, and the construction period was 5-7 days. In today's increasingly severe urban traffic pressure, excavation and repair with a long construction period cannot meet the requirements of rapid repair construction of urban inspection wells

The inspection well is reinforced and repaired by grouting, and the construction period is about 3 days, and the construction period is also long, and it cannot meet the requirements of corrosion resistance. While strengthening and repairing, the construction period is shortened and the corrosion resistance requirements of inspection wells are met, but the construction cost is relatively high
