Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a waterproof structure for through-wall pipe groups. Background Technology

[0002] During underground construction, cable conduits are typically designed to pass through walls. When there are many cables densely packed through the walls, a multi-conduit system is usually used. Traditional methods often involve installing a water-stop steel plate in the middle of the multi-conduit system. However, when formwork is installed around the multi-conduit system, the formwork cannot fit tightly against the system, resulting in loose concrete around the system, severe grout leakage, and serious water seepage problems.

[0003] Chinese patent application number 202420477689.6 discloses a waterproof structure for underground exterior walls using through-wall pipes, comprising: a concrete exterior wall and through-wall pipes arranged in an array, with one end of each pipe penetrating the concrete exterior wall. Waterproof connecting plates and external waterstops are welded to each through-wall pipe, with the external waterstop located inside the concrete exterior wall and the waterproof connecting plates located on the outside of the concrete exterior wall and flush with its outer end. A waterproof membrane is applied at the connection between the waterproof connecting plates and the concrete exterior wall, and an external waterproof layer is applied to the outer side of the concrete exterior wall. This underground exterior wall waterproof structure relies solely on the central external waterstop and the outer waterproof connecting plates for waterproofing, resulting in suboptimal waterproofing performance. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a through-wall group pipe waterproof structure that improves the overall waterproof effect.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A waterproof structure for through-wall pipes includes a concrete exterior wall and through-wall pipes arranged in an array. One end of each through-wall pipe passes through the concrete exterior wall. Each through-wall pipe is equipped with a water-stop ring and an outer water-stop plate. The water-stop ring is located inside the concrete exterior wall, and the outer water-stop plate is located outside the concrete exterior wall. The through-wall pipes are also equipped with an inner water-stop plate and a support plate. The inner water-stop plate is located inside the concrete exterior wall, and the support plate is located outside the concrete exterior wall. A waterproof layer is filled between the support plate and the outer water-stop plate, and the waterproof layer is fitted over the through-wall pipes.

[0006] As a further improvement to the above technical solution: The outer side of the concrete exterior wall is provided with a waterproof membrane, which extends between the outer waterstop and the waterproof layer.

[0007] The outer waterstop plate has a groove with an opening facing the waterproof layer. The waterproof membrane extends into the groove, which is filled with sealant, and the sealant adheres to the waterproof layer.

[0008] The portion of the waterproof membrane located within the groove is sandwiched between the bottom side of the groove and the sealant.

[0009] The portion of the waterproof membrane located within the groove is bonded and fixed to the bottom side of the groove.

[0010] The waterproof layer is an M20 mortar layer.

[0011] The water-stop ring, outer water-stop plate, inner water-stop plate, and support plate are all welded to the through-wall pipe group.

[0012] The water-stop ring, outer water-stop plate, inner water-stop plate, and support plate are all perpendicular to the through-wall pipe group.

[0013] The inner waterstop is flush with the inner side of the concrete exterior wall, and the outer waterstop is flush with the outer side of the concrete exterior wall.

[0014] The through-wall pipes are connected by a first grouting pipe and a second grouting pipe, with the grout outlets of the first grouting pipe and the second grouting pipe located on both sides of the water-stop ring.

[0015] Compared with the prior art, the advantages of this utility model are: Compared with the existing underground external wall through-wall waterproof structure, the waterproof structure of this utility model adds an inner waterstop plate inside the through-wall pipe at the concrete external wall and a support plate outside the through-wall pipe at the concrete external wall. A waterproof layer is filled between the support plate and the outer waterstop plate, which improves the overall waterproof effect. Attached Figure Description
