A structure for repairing water leakage in expansion joints of pools

Abstract

The invention discloses a water leakage repair structure for a water pool expansion joint. The water leakage repair structure for the water pool expansion joint comprises an expansion joint and a pool wall, and is characterized in that two supporting convex heads are arranged on the backwater surface of the pool wall; the two supporting convex heads are symmetrically arranged on the left side and the right side of the expansion joint; wall posts are fixedly arranged in the vertical direction of the two supporting convex heads; the wall posts are arranged closely to the pool wall along the expansion joint; the top surfaces of the wall posts are flush with the top surface of the pool wall; a first water stop band is vertically arranged between the two wall posts filled with a first sealant interlayer. According to the water leakage repair structure for the water pool expansion joint, disclosed by the invention, the water leakage is blocked, the deformation amount of the original design is retained, the production is not required to be stopped, the work period is short, the cost is low, and the water leakage repair structure for the water pool expansion joint can be widely applied to the non-stop-water repair of sewage plant structures and large-scale concrete pipeline expansion joints.

Description

technical field [0001] The invention belongs to the technical field of repairing expansion joints, and in particular relates to a water leakage repairing structure for expansion joints of pools. Background technique [0002] Most of the process structures of sewage treatment plants, large concrete pipes and general pools use embedded rubber waterstop expansion joints to deal with deformation caused by settlement and temperature. However, as the use time continues to increase, the rubber waterstop gradually oxidizes and cracks, or cracks due to large deformation, resulting in leakage of the pool body or pipeline. At present, the general repair method is to remove the outsourcing structure and replace the rubber waterstop and then re-cast; or add an externally attached rubber waterstop on the upstream surface; or directly pour with cement or waterstop glue. However, in several ways, the water body in the pool or pipeline must be emptied before construction and repair can be c...

AI Technical Summary

Problems solved by technology

However, in several ways, the water body in the pool or pipeline must be emptied before construction and repair can be carried out, and the construction period is long, and the economic cost and environmental cost of water stop maintenance are extremely high, especially for the structures of sewage treatment plants, etc. They are all pollutants. If they are emptied, they will affect the environment, and new pollutants will enter during the outage period and cannot be treated in time, causing further pollution and affecting the environment.

[0003] Insufficient existing technology: it is necessary to empty the water body in the pool or pipeline, stop its normal operation, and carry out construction repairs, which will increase economic costs and environmental costs
