Construction method for repairing ground deformation joint

Abstract

The invention discloses a construction method for repairing a ground deformation joint. The construction method comprises the steps that the surface layer of concrete is broken and removed; a water stopping wall is built; desilting is conducted, and leaking stoppage is conducted; the joint is filled with swelling water stopping strips, interface treatment is conducted, steel bars are embedded, anupturned beamn steel bar is arranged, a first grouting pipe is pre-buried, a first polyethylene foam plastic board is arranged, an upturned beam form board is arranged, and interface glue is smeared;a cement-based grouting material is grouted, maintenance is conducted, and the mold is removed; a first steel board water stopping belt is arranged, a beam steel bar, a second grouting pipe, box ironand angle iron are additionally installed, and a newly added beam form board is arranged; the cement-based grouting material is grouted, maintenance is conducted, and the mold is removed; an L-shapedsteel board is arranged, and grouting is arranged; a second polyethylene foam plastic board, a second steel board water stopping belt and a third steel board water stopping belt are arranged, non-solidified pitch is grouted, and a cover board is arranged; and a spray drain is arranged. The construction method protects the water stopping facility components so as to reduce corrosion damage to the deformation joint by arranging the multiple water stopping components, arranging the upturned beam and additionally installing the beam reinforcing deformation joint area, the water stopping and draining effects are good, and the quality of the deformation joint is improved.

Description

technical field [0001] The invention relates to the field of engineering construction, in particular to a construction method for repairing ground deformation joints. Background technique [0002] In existing projects, due to factors such as insufficient buoyancy resistance of the reinforced concrete floor and uneven settlement of the foundation, the structure of the deformation joint is severely damaged, and there is severe water seepage at the deformation joint, and the water-stop steel plate and rubber water-stop at the deformation joint There are different degrees of corrosion, damage, cracking, swelling, etc. in the belt, so it is necessary to carry out safe and high-quality remediation and repair on the deformation joints. Contents of the invention [0003] The purpose of the present invention is to overcome the existing projects in the prior art that often occur due to factors such as insufficient buoyancy resistance of the reinforced concrete floor, uneven foundati...
