Leakage repairing device for pressure-bearing reinforced concrete structure and construction method thereof

Abstract

A leakage repairing device for a pressure-bearing reinforced concrete structure comprises a double-layer sealing and reinforcing plate and a crack grouting and draining device, wherein the outer wall surface of a seepage crack portion is fixedly covered with the double-layer sealing and reinforcing plate. The double-layer sealing and reinforcing plate is composed of a rubber sealing backing plate on the inner side and a reinforcing steel plate on the outer side and is anchored to structure concrete around the seepage crack portion through expansion bolts around a plate body. The crack grouting and draining device is separately arranged on the upper side and the lower side of the seepage crack portion and comprises a grouting pipe at the upper portion and a first draining pipe at the lower portion. The outer wall surface of the seepage crack portion is provided with a flow guide groove through which a plurality of cracks are communicated. The grouting pipe, the flow guide groove and the first draining pipe are communicated. The leakage repairing device can be quickly manufactured at the construction site, the whole structure repairing process only takes several minutes, the leakage repairing device can be conveniently disassembled in the later stage without influencing the appearance of the concrete structure, and the solution method high in efficiency and fast to implement in a limited construction period is achieved.

Description

technical field [0001] The invention belongs to the field of application and building construction, in particular to a repair device and a construction method thereof when leakage occurs in a pressure-bearing reinforced concrete structure. Background technique [0002] In the field of building construction, the pressure flowing water system has high requirements on the bearing strength of the structure. If the construction quality is not effectively controlled, the structure will easily cause water seepage and leakage of the concrete structure during the system pressure test stage. In the past, when this kind of problem occurred, it was mainly adopted to empty the water storage in the pressure flow water system, and then carry out structural repairs, local water seepage tests, and secondary system anti-seepage tests at the water seepage points. However, if this water delivery system When it comes to the water diversion project of the water source, the cooling circulating wat...
