Restoration device and method thereof for breaking of waterproof structure of deformation joint of underground pipe rack

Abstract

The invention discloses a restoration device for breaking of a waterproof structure of a deformation joint of an underground pipe rack. The restoration device comprises a first water stop device and asecond water stop device, wherein the first water stop device is positioned in the middle part of the deformation joint; the second water stop device is positioned at the outer edge, near the insidewall of an underground pipe rack, of the deformation joint; the first water stop device comprises a wing tooth-shaped rubber water stop strip and a tightening round bar, and the tightening round bar is accommodated into the wing tooth-shaped rubber water stop strip; the second water stop device comprises a deep U-shaped rubber water stop band and an expansion bolt, and the expansion bolt is used for fixing the deep U-shaped rubber water stop band at the outer edge of the deformation joint; both sides of the outer edge of the deformation joint are cut, and form a Y-shaped opening together withthe deformation joint; both sides of the deep U-shaped rubber water stop band are fixedly arranged on the concrete base surfaces of the two side walls of the Y-shaped opening; the middle part of the deep U-shaped rubber water stop band is accommodated into the deformation joint. The restoration device for the breaking of the waterproof structure of the deformation joint of the underground pipe rack has the advantages that the problems of water permeating and sand surging of the underground pipe rack can be quickly and efficiently solved, and the functionality and integrity of the waterproof structure are restored.

Description

technical field [0001] The invention relates to the technical field of pipe gallery waterproofing, in particular to a repairing device and method for breaking waterproof structures of underground pipe gallery deformation joints. Background technique [0002] The comprehensive pipe gallery, also known as the underground pipe gallery and common ditch, is a comprehensive corridor of urban underground pipes, that is, a tunnel space is built underground to organically integrate various engineering pipelines such as power, communication, gas, heating, water supply and drainage, etc., to realize Unified planning, design, construction and management. The comprehensive pipe gallery is an urban municipal infrastructure project commonly used in developed countries. With the acceleration of the urbanization process in our country, many areas have begun to explore the construction of the pipe gallery. The comprehensive pipe gallery has become a new field that can be expanded underground ...
