Abstract
The invention discloses a detection boring rapid restoration support mould apparatus for concrete drain pipe culvert and a restoration method thereof. The apparatus includes a first baffle plate, a second baffle plate, a third baffle plate, a first fixing connection pole, a second fixing connection pole, a third fixing connection pole, a fourth fixing connection pole and a connection pole positioning assembly. The apparatus obviates the need for workers to enter the drain pipe culvert for conducting support mould in the implementation, which reduces cost and construction risks. The boring bottom baffle plate can entirely cover the bottom part of the entire boring, which can prevent slurry leakage with the enclosure formed by a water sealing material. For a short term, under circumstances that the grouting material or a high-early-strength cement mortar in the boring is not dry, if the internal water pressure within the pipe culvert is restored, the boring bottom baffle plate can bear the water pressure and prevent leakage of the polluted water. For a long term, under the circumstances when the boring is full grouted after restoration, the concrete formed after grouting the boring has a thickness the same as that of an adjacent pipe wall, can bear intra-pipe water pressure and is conductive to structure bearing.
