Method for repairing inspection well and similar structure
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.
