As stated in the background section, the inventors of the present application have discovered, in the course of improving upon prior art solutions, that leakage into through-wall tubing is commonly addressed by grouting. The dominant hidden trouble point of the wall penetrating pipe leakage is a leakage water channel on the outer wall of the wall penetrating pipe, but after the wall penetrating pipe of the wall is abandoned, the indoor wall penetrating pipe can be cut off along the surface of the wall structure, the wall penetrating pipe is plugged by adopting materials such as cement mortar and the like to recover the wall facing layer, and no other waterproof structure exists. The abandoned wall penetrating pipe is corroded by underground water at the outdoor part, the wall penetrating pipe is easy to rust and damage, and the underground water leaks into the room along the structural wall body. For the environment of repairing for a long time and soaking in the groundwater environment for a long time, the wall penetrating pipe wall can be corroded and damaged, so that the leakage risk is extremely high. Namely, the scheme can only solve part of problems, but can not solve the leakage problem caused by the corrosion of the outside water inside the wall penetrating pipe and the wall penetrating pipe.

In order to solve the problems in the prior art, the embodiment of the application provides an anti-leakage structure of a wall penetrating pipe and a maintenance method, and aims to solve the problems of leakage caused by corrosion and damage of gaps between the outer wall of the wall penetrating pipe and a wall, hollow parts inside the wall penetrating pipe and the wall penetrating pipe.

The anti-leakage structure of the wall pipe provided by the embodiment of the application is described below. Fig. 1 shows a schematic view of an anti-leakage structure of a wall pipe according to an embodiment of the present application.

As shown in fig. 1, the leakage preventing structure of the wall penetrating pipe is used for repairing and forming the wall penetrating pipe 2 which is arranged in the underground wall 1 and leaks, and the leakage preventing structure of the wall penetrating pipe comprises: the grouting sealing structure 4 is arranged between the wall penetrating pipe and the wall 1 around the outer peripheral side of the wall penetrating pipe 2; the gap blocking structure 5 is connected with the grouting sealing structure 4 along the axial direction of the wall penetrating pipe 2, and the radial thickness from the grouting sealing structure to the gap blocking structure gradually increases gradually; the pipeline plugging structure 6 is arranged inside the wall penetrating pipe 2 and is used for plugging at least part of the wall penetrating pipe 2 arranged inside the wall 1 from inside; the integral covering structure 7 is connected to the gap blocking structure 5 and the pipeline blocking structure 6 in a sealing manner, and extends to cover the surface of the wall 1 through which the through-wall pipe 2 is arranged.

According to the anti-leakage structure of the through-wall pipe, the gap between the through-wall pipe and a wall is sealed through the grouting sealing structure and the gap blocking structure, the channel in the through-wall pipe arranged in the wall is sealed through the pipeline blocking structure, and the channel in which the through-wall pipe leaks is sealed through the integral covering structure, the gap blocking structure and the pipeline blocking structure, namely, the anti-leakage structure can thoroughly prevent outside water from penetrating into a room through the through-wall pipe in the wall in a three-in-one mode.

In the embodiment of the application, the gap blocking structure and the pipeline blocking structure of the anti-seepage structure of the wall penetrating pipe can protrude out of the indoor side elevation of the wall, or are flush with the indoor side elevation of the wall, or are positioned in the wall, and are in sealing connection with the integral covering structure to form the anti-seepage structure of the wall penetrating pipe with three different structures, so that the effect of preventing outside water from penetrating into a room through the wall penetrating pipe in the wall is achieved.

In some embodiments, the end portions of the gap plugging structure 5 and the pipe plugging structure 6 facing the integral covering structure 7 are located in the wall 1, so as to enhance the connection strength between the gap plugging structure 5 and the pipe plugging structure 6 and the integral covering structure 7, and further enable the integral covering structure 7 to be in sealing connection with the gap plugging structure 5 and the pipe plugging structure 6 in the wall, so as to form an anti-leakage structure of the through-wall pipe flush with the inner side elevation of the wall, or an anti-leakage structure of the through-wall pipe gently protruding from the inner side elevation of the wall.

In some embodiments, as shown in fig. 1, the pipe blocking structure 6 protrudes from the gap blocking structure 5 to form a concave-convex structure, enhancing the connection strength between the gap blocking structure 5 and the pipe blocking structure 6 and the overall covering structure 7. It will be appreciated that in other embodiments, the gap closure structure 5 protrudes beyond the pipe closure structure 6, and that it is also possible to form a relief structure, enhancing the strength of the connection between the gap closure structure 5 and the pipe closure structure 6 and the unitary cover structure 7. Or the part or interval of the gap blocking structure 5 around the periphery of the wall penetrating pipe protrudes or is shorter than the pipeline blocking structure 6, so that the gap blocking structure 5 and the pipeline blocking structure 6 can form annular continuous or interval concave-convex structures.

In some embodiments, the gap blocking structure 5 comprises: the first blocking layer 51 is at least partially filled between the wall pipe 2 and the wall 1. That is, the gap blocking structure 5 only comprises the first blocking layer 51, and the gap blocking structure 5 formed by the first blocking layer 51 plays a role in blocking water leakage in the cavity between the through-wall pipe and the wall.

It will be appreciated that the gap closure structure 5 may also comprise only the first closure layer 51, or comprise the first closure layer 51, the water-stop sealing layer 52, the second closure layer 53, or further comprise the gap filling layer 50. For the gap filling layer 50 formed by the gap filler having the sealing waterproof property partially, the gap blocking structure 5 may further include the gap filling layer 50, the water blocking layer 52, and the second blocking layer 53. The gap plugging structure provided by the application has better plugging effect on water leakage than that of a three-layer gap plugging structure. The application does not limit the thickness of each structural layer of the gap plugging structure, so that the waterproof sealing of the cavity can be realized as minimum requirement.
