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.
