[0002] The waterproofing of pipelines in prefabricated buildings refers to the waterproofing at the connection between the part of the embedded pipeline extending out of the wall and the wall. The existing waterproofing method is to use a water stop plate and a sealing ring to waterproof the connection part between the pipeline and the wall. This kind of waterproof device has the following defects: First, a water isolation ring is generally designed on the water stop plate, and the water isolation ring is embedded in the wall to ensure the waterproofness of the contact part between the water stop plate and the wall. However, when installing and using this kind of water stop plate, a groove for accommodating the water isolation ring needs to be opened on the wall, and the waterproof layer needs to be recoated, resulting in a long installation time. Moreover, the water stop plate also needs to be fixed with bolts, thus affecting the construction efficiency and waterproofness. Second, the sealing ring is prone to deformation during the assembly process, thus affecting the waterproofness between the water stop plate and the pipeline. In addition, the elasticity of the sealing ring will gradually decrease, resulting in a gradually deteriorating waterproof effect. Summary of the Utility Model

[0024] Working principle: When using the present utility model, the embedded blind pipe 1 is sleeved on the pipe body 4, and the embedded blind pipe 1 and the pipe body 4 are cast in the assembled wall 5, so that the sleeve 13 on the embedded blind pipe 1 is exposed outside. Then, a waterproof layer 6 is applied on the surface of the wall 5, and the waterproof layer 6 covers the upper end surface of the embedded blind pipe 1 to ensure the waterproofness of the joint part between the embedded blind pipe 1 and the wall 5. Then, the mounting seat 2 is installed on the sleeve 13, so that the sleeve 13 is sleeved in the first mounting groove 21, and the first internal thread 14 and the first external thread 22 are threadedly connected. Then, the integrated support structure composed of the ring plate 36, the first elastic piece 38 and the second elastic piece 39 is installed in the second mounting groove 32 of the sealing ring 31, so that the insertion block 33 is inserted into the jack 37 to fix the ring plate 36.

The first elastic piece 38 and the second elastic piece 39 slide along the first convex ring 26 and deform in the direction away from the first convex ring 26, so that the sealing ring 35 on the outer side of the sealing ring 31 fits against the inner wall of the mounting hole 25, and the sealing ring 35 on the inner side of the sealing ring 31 fits against the outer wall of the pipe body 4. Since the first elastic piece 38 and the second elastic piece 39 are in a deformed state, after the elasticity of the sealing ring 31 weakens, under the reset action of the first elastic piece 38 and the second elastic piece 39, the sealing ring 35 can still fit against the inner wall of the mounting hole 25 and the outer wall of the pipe body 4. Among them, the through groove 11 is used to accommodate concrete, the first through hole 12 and the second through hole 23 are used to accommodate the pipe body 4, and the rib plate 24 is used to improve the structural strength of the mounting seat 2.
