If the periphery of the wall-penetrating pipe is not tightly sealed or the waterproof layer is not tightly connected around the pipe, water may seep out along the pipe and cause leakage at the junction of the pipe and the wall. Therefore, the waterproofing of wall-penetrating pipes is an important part of building waterproofing projects. Utility Model Content

[0010] Preferably, two baffles are provided, and the two baffles are fixedly connected to the two ends of the tube body respectively.
[0011] By adopting the above technical solution, the baffle covers the junction between the inside and outside of the wall, reducing the probability of external water intruding into the junction between the pipe and the wall, and improving the waterproofness of the pipe penetrating the wall.
[0012] Preferably, a retaining ring is connected to one end of the baffle plate facing the tube body, and the inner wall of the tube body is threadedly connected to the outer wall of the retaining ring.
[0013] By adopting the above technical solution, it is easy to assemble the wall-penetrating pipe, which has a simple structure, is easy to operate, and improves the installation efficiency. Due to the different thickness of the wall, the pipe body needs to adopt different lengths. The pipe body and the baffle are processed separately, which is convenient for processing the baffle standard parts and subsequent construction and replacement.
[0014] Preferably, a wall-penetrating pipe further comprises a sealing ring, one side of the sealing ring is fixedly connected to the end of the pipe body, and the other side of the sealing ring is used to abut against the baffle.

[0017] By adopting the above technical solution, the probability of external water penetrating into the joint between the baffle and the wall after cracks appear on the baffle is reduced, thereby improving the waterproofness of the wall-penetrating pipe.
[0018] Preferably, a wall-penetrating pipe further comprises a sealing ring, wherein the sealing ring is sleeved on the outer periphery of the baffle, and the outer wall of the sealing ring is used to fit into a preset groove of the wall.
[0019] By adopting the above technical solution, the sealing ring makes it difficult for external moisture to penetrate into the joint between the baffle and the wall, thereby improving the waterproofness of the wall-penetrating pipe.
[0020] Preferably, a convex ridge is connected to a side of the baffle away from the tube body.

[0022] Preferably, there are a plurality of convex ridges, and the plurality of convex ridges are evenly spaced around the axis of the tube body.
[0023] By adopting the above technical solution, multiple convex ridges make it easier for operators to apply force, so that the baffle rotates and presses against the wall, thereby enhancing the sealing performance.
