Non-excavation leaking inspection well repairing method and repairing structure
The invention relates to a non-excavation leaking inspection well repairing method and a repairing structure and belongs to the technical field of transformation of urban public pipeline facilities. The method comprises the steps that firstly, water accumulated in an inspection well is completely discharged, and a water leakage point is checked out; the water leakage point is blocked by means of a rapid-hardening anti-leakage concrete leaking stoppage agent on the inner wall of the inspection well; wet maintenance is conducted; primary single-layer shale brick walls are constructed on the inner wall and a base plate of the inspection well, brick wall seams are filled with waterproof mortar, and troweling is conducted on the inner side by means of waterproof mortar; after the strength meets the requirement, an SBS elastomer modified asphalt waterproof sheet material layer is integrally constructed on the inner side of the inspection well; a protective layer is constructed outside the waterproof sheet material layer again by means of shale bricks; and finally, the interior of the inspection well is flattened by means of waterproof mortar. The repairing structure comprises a leaking stoppage agent layer, the primary shale brick lining walls, the waterproof sheet material layer, last shale brick lining walls and a waterproof mortar layer which are added to the original inspection well. By the adoption of the non-excavation leaking inspection well repairing method and the repairing structure, the structural strength of a well chamber can be improved, maintenance cost can be reduced, and the problem of leakage of the inspection well can be solved.
