Description

Seepage-proofing reinforcing structure of newly-added rigid waterproof sleeve on side wall of existing pool Technical Field The utility model relates to the technical field of civil engineering and waterproofing, in particular to an anti-seepage reinforcing structure of a waterproof sleeve pipe with newly-added rigidity on the side wall of an existing pool. Background In order to save construction cost and free house property, the prior building is often modified by taking measures of 'utilizing old and modifying', so that the prior building meets the requirements of the current national standard, wherein a great amount of construction cost can be saved by utilizing the prior fire water pool to supply water. Taking water from the existing fire water pond, the side wall of the fire water pond is required to be perforated and a waterproof sleeve is required to be installed. Because the side wall of the water tank needs to bear larger lateral water pressure in a full water state, corresponding seepage prevention and reinforcement measures are needed to treat the side wall of the water tank after the water tank is opened in order to ensure that the side wall of the water tank after the water tank is opened has enough seepage resistance and safety. The national building standard design drawing is concentrated, the concrete structure reinforcing structure (13G 311-1) stipulates that after a hole is formed in a concrete structure, the existing steel bars at the position of the hole are required to be protected and anchored by a newly added concrete layer, and flat steel is stuck at the periphery of the hole to reinforce the reinforced concrete wall. The method is simple and convenient to operate, but does not relate to the installation of the rigid waterproof sleeve and the anti-seepage treatment of the wall body, and is only suitable for reinforcing the newly added hole of the conventional reinforced concrete wall body. The Chinese patent of the invention with the publication number of CN 112538893B discloses a structure of opening a hole through a side wall of a current pool, a pipe joint is fixed at a hole of the current pool wall through secondary pouring concrete, a fixed reinforcing steel bar is implanted into the current pool wall, a hole reinforcing outer side ring rib is bound on the fixed reinforcing steel bar, a hole reinforcing inner side ring rib is bound on the pipe joint, and the fixed reinforcing steel bar and the hole reinforcing outer side ring rib are both positioned in the secondary pouring reinforced concrete. The method realizes that the connecting pipe is opened on the wall of the pool in the state of full water or short empty pool, and indirectly reinforces the wall of the pool after opening. When the method is adopted, the water stop steel sheet on the sleeve and the secondarily poured reinforced concrete structure are both positioned on the outer side of the side wall of the current pool, the integrity is poor, the impermeability is weak, the indirect reinforcing measure is positioned in the compressed area on the outer side of the pool wall, and the tension area on the inner side of the pool wall is not reinforced. The Chinese patent publication No. CN 211342004U discloses a construction structure for reinforcing and preventing leakage of the side wall hole of the old water tank, wherein two ends of a newly added L-shaped steel bar are respectively welded and connected with a steel waterproof sleeve and a steel bar cut off by a hole in the water tank wall, and a micro-expansion secondary grouting material layer is filled between the steel waterproof sleeve and the concrete of the hole of the water tank wall. The concrete inner wall of the water tank wall opening is provided with a V-shaped ring groove, and the micro-expansion secondary grouting material layer is embedded into the V-shaped ring groove. When the method is adopted, the water stop rings on the steel waterproof sleeve are positioned on the inner surface and the outer surface of the side wall of the current pool, no water stop bars are arranged on the joint surface of the new concrete and the old concrete, the impermeability is weaker, the steel waterproof sleeve is indirectly connected with the steel bars cut off by the holes in the pool wall, and the steel waterproof sleeve is easy to deform. The Chinese patent publication No. CN 213809244U discloses a plugging structure between a pool wall and a water pipe wall after a pool wall of a water pool is provided with a hole, square holes are formed in the side wall of the water pool, three steel plates and wall penetrating bolts which are connected with each other are adopted to reinforce the side wall after the hole is formed, a third steel plate arranged on the pool wall of an upstream surface is provided with a second through hole, a round water pipe penetrates through the second through hole and square holes on the side wall of the water pool, a waterproof material transition
