[0002] Currently, with the development of the construction industry, more and more buildings have basements, leading to increasingly higher requirements for waterproofing of basement exterior walls. Leakage at joints in basement exterior walls is a common quality defect. The root cause of leaks and seepage is the sealing of pre-embedded through-wall sleeves. Traditional installation of basement exterior wall sleeves is time-consuming, labor-intensive, and carries a high risk of leakage, resulting in high labor intensity for construction workers, slow construction efficiency, and a tendency for leaks and seepage. Utility Model Content
[0003] To address the aforementioned issues, this application provides a pre-embedded device for preventing water leakage in the exterior walls of basements.

A connecting pipe is fitted at one end of the through-wall sleeve near the outer side of the exterior wall of the basement. A first inner plate is fixedly connected to the connecting pipe and embedded in the exterior wall of the basement. A waterproof pipe is fitted on the connecting pipe. A second inner plate is fixedly connected at one end of the through-wall sleeve near the inner side of the exterior wall of the basement and embedded in the exterior wall of the basement.
[0006] By adopting the above technical solution, when it is necessary to install a through-wall sleeve, the construction workers insert the through-wall sleeve from the inside of the basement exterior wall. The movement of the through-wall sleeve can drive the movement of the second inner panel, so that the second inner panel is embedded in the basement exterior wall. Then, the connecting pipe is sleeved on the other end of the through-wall sleeve, and the first inner panel is embedded in the basement exterior wall. After that, the waterproof pipe is sleeved on the connecting pipe, thereby realizing the installation of the pre-embedded device, reducing the labor intensity of the construction workers and improving the construction efficiency.
[0007] Preferably, the first inner panel has a first embedding groove, and one end of the waterproof tube is embedded in the first embedding groove.
[0008] By adopting the above technical solution, the first embedded groove can limit the waterproof pipe and improve the sealing degree between the waterproof pipe and the first inner plate, reducing water seepage and leakage.
[0009] Preferably, an auxiliary ring is fixedly connected to the waterproof pipe, and the auxiliary ring has an auxiliary inclined surface.
[0010] By adopting the above technical solution, the auxiliary ring can further improve the sealing degree between the waterproof pipe and the first inner plate, and the auxiliary inclined surface can guide the flow of water, reducing the possibility of water entering between the waterproof pipe and the first inner plate.
[0011] Preferably, a rubber layer is fixedly connected to the auxiliary ring, and a second embedding groove is provided at the opening of the first embedding groove. The rubber layer is embedded in the second embedding groove, and the bottom of the rubber layer and the second embedding groove are in contact.
[0012] By adopting the above technical solution, the rubber layer can improve the sealing degree between the auxiliary ring and the first inner plate, and the second embedding groove can raise the installation position of the rubber layer and limit the rubber layer, thereby facilitating the installation of the waterproof pipe.
[0013] Preferably, a limiting block is fixedly connected to the inner wall of the waterproof pipe, the limiting block abuts against one end of the connecting pipe, a limiting groove is formed on the limiting block, and the bottom of the limiting groove fits against the outer wall of the through-wall sleeve.
[0014] By adopting the above technical solution, when the waterproof pipe is sleeved on the connecting pipe, the outer wall of the through-wall sleeve and the bottom of the limiting groove fit together, thereby limiting the limiting block and the waterproof pipe; when the waterproof pipe moves the limiting block to abut against one end of the connecting pipe, the connecting block can limit the limiting block, thereby improving the positional accuracy of the waterproof pipe.
[0015] Preferably, an inclined plate is fixedly connected to the second inner panel, the inclined plate is inclined, and a horizontal plate is fixedly connected to the inclined plate, the horizontal plate being embedded in the basement exterior wall.
[0016] By adopting the above technical solution, when the through-wall sleeve drives the second inner panel to be embedded in the basement exterior wall, the movement of the second inner panel can drive the movement of the inclined plate, and the inclined plate can drive the movement of the horizontal plate, so that the horizontal plate is embedded in the basement exterior wall. The horizontal plate can protect the second inner panel and reduce the possibility of water flowing to the second inner panel. The inclined plate can provide flow guidance for water and facilitate the outflow of water.
[0017] In summary, this application includes at least one of the following beneficial technical effects:
[0018] 1. By setting up a connecting pipe, a first inner plate, a waterproof pipe, and a second inner plate, when it is necessary to install a through-wall sleeve, the construction workers insert the through-wall sleeve from the inside of the basement exterior wall.

Then, the connecting pipe is sleeved on the other end of the through-wall sleeve, and the first inner plate is embedded in the basement exterior wall. After that, the waterproof pipe is sleeved on the connecting pipe, thereby realizing the installation of the pre-embedded device, reducing the labor intensity of the construction workers and improving the construction efficiency.

By setting up limiting blocks and limiting grooves, when the waterproof pipe is sleeved on the connecting pipe, the outer wall of the through-wall sleeve and the bottom of the limiting groove fit together, thereby limiting the limiting block and the waterproof pipe; when the waterproof pipe moves the limiting block to abut against one end of the connecting pipe, the connecting block can limit the limiting block, thereby improving the positional accuracy of the waterproof pipe.

Detailed Implementation
[0025] To make the inventive objectives, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0026] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.
[0027] This application discloses an embedded device for waterproofing basement exterior walls, such as... Figure 1 As shown, it includes a through-wall sleeve 1 installed in the outer wall of the basement, through which wiring passes. A connecting pipe 2 is fitted at one end of the through-wall sleeve 1 near the outer side of the outer wall of the basement, and a first inner plate 3 is fixedly connected to the connecting pipe 2. The first inner plate 3 is embedded in the outer wall of the basement.
[0028] like Figure 2 and 3 As shown, a waterproof pipe 4 is fitted onto the connecting pipe 2, and a first embedding groove 31 is provided on the first inner plate 3. One end of the waterproof pipe 4 is embedded in the first embedding groove 31. The first embedding groove 31 can limit the position of the waterproof pipe 4 and improve the sealing degree between the waterproof pipe 4 and the first inner plate 3, reducing the possibility of water seepage and leakage.
[0029] like Figure 2 As shown, an auxiliary ring 6 is fixedly connected to the waterproof pipe 4, and an auxiliary inclined surface 61 is provided on the auxiliary ring 6. The auxiliary ring 6 can further improve the sealing degree between the waterproof pipe 4 and the first inner plate 3, and the auxiliary inclined surface 61 can guide the flow of water and reduce the possibility of water entering between the waterproof pipe 4 and the first inner plate 3.
[0030] like Figure 2 and 3 As shown, a rubber layer 62 is fixedly connected to the auxiliary ring 6. A second embedding groove 32 is provided at the opening of the first embedding groove 31. The rubber layer 62 is embedded in the second embedding groove 32, and the bottoms of the rubber layer 62 and the second embedding groove 32 are in contact. The rubber layer 62 can improve the sealing degree between the auxiliary ring 6 and the first inner plate 3. The second embedding groove 32 can raise the installation position of the rubber layer 62 and limit the rubber layer 62, thereby facilitating the installation of the waterproof pipe 4.
[0031] like Figure 2 As shown, a limiting block 7 is fixedly connected to the inner wall of the waterproof pipe 4. The limiting block 7 abuts against one end of the connecting pipe 2. A limiting groove 71 is formed on the limiting block 7, and the bottom of the groove 71 fits against the outer wall of the through-wall sleeve 1. When the waterproof pipe 4 is fitted onto the connecting pipe 2, the outer wall of the through-wall sleeve 1 fits against the bottom of the limiting groove 71, thereby limiting the limiting block 7 and the waterproof pipe 4. When the waterproof pipe 4 moves the limiting block 7 to abut against one end of the connecting pipe 2, the connecting block can limit the limiting block 7, thereby improving the positional accuracy of the waterproof pipe 4.
[0032] like Figure 4 As shown, a second inner panel 5 is fixedly connected to one end of the through-wall sleeve 1 near the inner side of the basement exterior wall, and the second inner panel 5 is embedded in the basement exterior wall. An inclined plate 51 is fixedly connected to the second inner panel 5, and the inclined plate 51 is inclined. A horizontal plate 52 is fixedly connected to the inclined plate 51, and the horizontal plate 52 is embedded in the basement exterior wall. When the through-wall sleeve 1 moves the second inner panel 5 into the basement exterior wall, the movement of the second inner panel 5 can move the inclined plate 51, which in turn moves the horizontal plate 52, causing the horizontal plate 52 to be embedded in the basement exterior wall. The horizontal plate 52 can protect the second inner panel 5, reducing the possibility of water flowing onto it, while the inclined plate 51 can provide flow guidance for water, facilitating water outflow.
[0033] The implementation principle of the pre-embedded device for preventing seepage in the exterior wall of a basement according to an embodiment of this application is as follows:
[0034] When it is necessary to install the through-wall sleeve 1, the construction workers insert the through-wall sleeve 1 from the inside of the basement exterior wall. The movement of the through-wall sleeve 1 can drive the movement of the second inner plate 5, so that the second inner plate 5 is embedded in the basement exterior wall. The second inner plate 5 can drive the movement of the inclined plate 51 and the horizontal plate 52, so that the horizontal plate 52 is embedded in the basement exterior wall.
[0035] The construction workers fitted the connecting pipe 2 onto the other end of the through-wall sleeve 1, and the first inner plate 3 was embedded in the basement exterior wall. Then, the waterproof pipe 4 was fitted onto the connecting pipe 2. The movement of the waterproof pipe 4 could drive the movement of the auxiliary ring 6 and the limiting block 7. The auxiliary ring 6 was embedded in the first embedding groove 31, and the limiting block 7 and the connecting pipe 2 abutted against each other, which improved the positional accuracy of the waterproof pipe 4 and facilitated the installation of the waterproof pipe 4.
[0036] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
