[0035] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.
[0036] Combine the following Figure 1 and Figure 2 , describing an embodiment of the utility model.
[0037] According to an embodiment of the utility model, a group-pipe wall-penetrating waterproof structure is provided, comprising:
[0038] The group pipe comprises a plurality of wall-penetrating pipes 1 arranged at intervals, and the wall-penetrating pipes 1 are suitable for passing through a wall 2;
[0039] The encapsulation shell 3 is connected to the water-facing surface of the wall 2 and wraps part of the structure of the outdoor area of the group pipe to be suitable for sealing the gap between the wall-penetrating pipe 1 and the wall 2;
[0040] The waterproof structure 4 is arranged at the junction of the encapsulating shell 3 and the wall 2 . The waterproof structure 4 is connected to the outer wall of the encapsulating shell 3 and the water-facing surface of the wall 2 at the same time, so as to be suitable for sealing the gap between the encapsulating shell 3 and the wall 2 .
[0041] The group pipe wall-penetrating waterproof structure provided in the present embodiment wraps part of the structure of the outdoor area of the group pipe by the encapsulation shell 3 to seal the gap between the wall-penetrating pipe 1 and the wall 2, and seals the gap between the encapsulation shell 3 and the wall 2 by the waterproof structure 4, thereby solving the problem that the group pipe is difficult to close when passing through the wall, improving the waterproof effect of the external wall, the rigidity of the group pipe and the integrity of the group pipe, and reducing water leakage of the external wall.
[0042] Specifically, the encapsulating shell 3 is box-shaped or hemispherical, and the side shape of the encapsulating shell 3 close to the wall 2 is adapted to the water-facing surface shape of the wall 2, so that the encapsulating shell 3 is fully connected with the wall 2. Preferably, the encapsulating shell 3 is made of steel plate, and the side of the encapsulating shell 3 close to the wall 2 has an opening. After the wall-penetrating pipe 1 passes through the wall 2 in the direction from indoors to outdoors, it is suitable to enter the interior of the encapsulating shell 3 through the opening, and pass through the side wall of the encapsulating shell 3 away from the wall 2, and the joints between the wall-penetrating pipe 1 and the side walls of the encapsulating shell 3 are tightly welded, and / or sealing paste is applied to the joints between the wall-penetrating pipe 1 and the side walls of the encapsulating shell 3, so that the encapsulating shell 3 seals the gap between the wall-penetrating pipe 1 and the wall 2. A waterproof structure 4 is provided at the junction of the encapsulating shell 3 and the wall 2 to seal the gap between the encapsulating shell 3 and the wall 2, thereby ensuring the waterproof effect of the group pipe through the wall waterproof structure through the encapsulating shell 3 and the waterproof structure 4, thereby improving the waterproof effect of the outdoor side of the wall 2 through the wall structure and reducing the water leakage of the external wall. In the related art, the waterproof method of the group pipe through the wall is usually a pre-formed full-outsourcing waterproof method, that is, a box-type structure is made of steel plates and pre-buried pipes, self-leveling non-shrinkage mortar is poured inside the box-type structure, and the box-type structure is pre-buried in the wall structure. However, in addition to the poor waterproof effect on the outdoor side, this method also requires the disconnection of the main structural steel bars in the wall 2, which will have an adverse effect on the stress of the wall 2 structure, and the components are large and difficult to install and fix. The group pipe through the wall waterproof structure provided in this embodiment does not need to disconnect the main structural steel bars, which can ensure that the stress of the wall 2 structure meets the requirements, and the group pipe through the wall waterproof structure has a simple structure and is easy to process and manufacture, which can avoid the problem that the components of the box structure are large and difficult to install.

It should be noted that sealing paste is a common building sealing material and will not be described in detail here.

[0047] The pipe-through-the-wall waterproof structure provided in this embodiment enables the waterproof layer 42 to cover the first sealing paste layer 41 so as to isolate the contact between moisture and the first sealing paste layer 41 , which is beneficial to improving the waterproof effect at the first sealing paste layer 41 .
[0048] Specifically, the waterproof layer 42 is constructed of a waterproof roll, which is applied to the outer side wall of the encapsulating shell 3. Preferably, the waterproof roll is tied to the side wall of the encapsulating shell 3 by a binding member, and the binding member includes a metal wire or a non-metal wire to prevent the waterproof roll from detaching from the side wall of the encapsulating shell 3. The waterproof roll extends from the outer side wall of the encapsulating shell 3 to the water-facing surface of the wall 2 and is applied to the wall 2. The waterproof roll covers the first sealing paste layer 41 to isolate the first sealing paste layer 41 from external moisture, thereby forming a seal on the first sealing paste layer 41, and further improving the waterproof effect at the first sealing paste layer 41.
