Embodiment Construction

[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] The invention discloses a non-stop water repair method for expansion joints of sewage treatment structures, which comprises the following steps:

[0026] S1. Remove the caulking material on the surface of the waterstop of the expansion joint to be repaired at the preset height section of the bottom surface of the structure and the lower side of the side to form a caulking;

[0027] The preset height can be determined according to the actual situation, preferably 100mm to 500mm. The caulking material above the waterstop can be removed with a hammer and chisel. During the removal process, all caulking materials need to be removed, especially the concrete interface with the seam wall. If the wall thickness of the entire sewage treatment structure is 500mm, the waterstop is usually installed at a depth of 250mm, so the length of the chisel into the caulki...

Abstract

The invention discloses a continuous-water-supply repairing method of sewage treatment structure expansion joints. The method includes following steps: removing caulked joint materials on the surfacesof waterstops of to-be-repaired expansion joints of preset height sections at the lower ends of the undersurface and the side face of a structure to form caulked joints; filling each caulked joint with a sealant to form a sealant layer with the upper surface lower than the edge of the caulked joint; embedding a water-swelling waterstop strip in each caulked joint, wherein the lower surface of each the water-swelling waterstop strip is in close fit with the upper surface of the corresponding sealant layer; on each water-swelling waterstop strip, coating and filling a sealing agent at a position where each water-swelling waterstop strip and the corresponding caulked joint are connected and at the edge of each caulked joint. The invention further discloses a continuous-water-supply repairingstructure formed by adopting the method.

Description

technical field [0001] The invention relates to the technical field of expansion joint repair, in particular to a non-stop water repair method and repair structure for expansion joints of sewage treatment structures. Background technique [0002] Usually, structures are artificial structures that do not have, contain or provide human habitation functions, such as water towers, pools, filter ponds, clarifiers, biogas digesters, etc. In the sewage treatment industry, sewage treatment structures are mainly the types of engineering equipment for each treatment unit in the process of sewage treatment. Such as regulating tanks, grids, grit chambers, sedimentation tanks, aeration tanks, sewage disinfection tanks, sludge digestion tanks, hydrolytic acidification tanks, air flotation tanks, grease traps, filters, biological contact oxidation tanks, etc. [0003] Such as figure 1 As shown, the expansion joints of existing sewage treatment structures include waterstops and caulking m...
