[0023] Example 1

[0024] As the instruction manual Figure 1 As shown, the utility model provides a pre-buried sleeve for the outer wall of a basement, comprising an outer pipe 1, an inner pipe 2 and two water-stopping joints 3. The inner pipe 2 is arranged in the outer pipe 1, and a filling cavity is formed between the inner pipe 2 and the outer pipe 1. A sealing filling layer 4 is provided in the filling cavity. The two water-stopping joints 3 are respectively arranged at both ends of the inner pipe 2, and the ends of the two water-stopping joints 3 that are open toward the outer pipe 1 are respectively provided with external pipe interfaces 31.

[0025] Specifically, the embedded sleeve is a prefabricated product and can be prefabricated in a factory. The inner pipe 2 is placed in the outer pipe 1, and water stop joints 3 are provided at both ends of the inner pipe 2. A sealing filling layer 4 is filled between the inner and outer pipes. The factory prefabrication production process is adopted, and after batch production line processing, centralized water testing is carried out. After passing the test, the product is numbered and prefabricated for installation. First, it is prefabricated in the factory, and the product consistency is good and the quality is controllable, which can ensure the quality of the prefabricated sleeve and has strong anti-leakage performance; second, the finished embedded sleeve can be directly installed and used at the construction site, saving on-site construction time; third, there is no need to seal the gap between the inner and outer pipes in the later stage, and the external pipe interfaces reserved on the inner and outer sides can be connected normally, which can avoid the need for rework due to poor on-site sealing and can effectively improve on-site construction efficiency; fourth, various types of embedded sleeves can be made according to different external pipe diameters, which have a wide range of applicability.

[0026] The inner pipe 2 is provided with a water stop joint 3 at both ends, and a sealing filling layer 4 is provided between the inner and outer pipes. The three-layer water-stopping technology is adopted to make the finished embedded sleeve, which has good anti-leakage performance, can solve the problem of water leakage of the basement wall pipe, and realize the elimination of blocking during the later on-site installation process.

[0027] In an optimized implementation method, the length of the inner pipe 2 is smaller than that of the outer pipe 1, and the inner pipe 2 is located inside the outer pipe 1. Both ends of the inner pipe 2 are connected to the water stop 3, and the external pipe interfaces 31 of the two water stop 3 are both located inside the outer pipe 1. The distance between the two external pipe interfaces 31 is smaller than the length of the outer pipe 1. On the one hand, it can ensure that when the external pipe is connected to the external pipe interface 31, the connection is located inside the outer pipe 1, and the outer pipe 1 can play a protective role. On the other hand, it is convenient for the construction of the exterior wall of the basement to place the outer pipe 1 between the formwork and then cast the wall. The inner pipe 2 and the water stop 3 inside the outer pipe 1 can be protected to prevent the poured concrete from damaging the inner pipe 2 and the water stop 3 and affecting their use.

[0028] In an optimized implementation mode, the distance between the external pipe interface 31 and the open end of the external pipe 1 on the corresponding side is not less than 30 mm, and a position for installing the external pipe is reserved.

[0029] In an optimized implementation method, the water-stop joint 3 includes a water-stop joint body 32 and a first water-stop ring 33. The inner pipe 2 is a hollow pipe. The water-stop joint body 32 is connected to the inner pipe 2 as a fluid channel. One end of the water-stop joint body 32 is connected to the inner pipe 2, and the other end is an external pipe interface 31. After the external pipe is connected to the external pipe interface 31, the fluid can flow through the external pipe on one side of the pre-buried pipe in sequence through the water-stop joint body 32, the inner pipe 2, the water-stop joint body 32, and finally to the external pipe on the other side of the pre-buried pipe. The first water-stop ring 33 is mounted on the water-stop joint body 32. The sealing filling layer 4 is located between the first water-stop rings 33 of the two water-stop joints 3. The first water-stop ring 33 is connected to the sealing filling layer 4, which can enhance the connection reliability between the sealing filling layer 4 and the inner pipe 2 and the water-stop joint 3. The water-stop joint 3 and the sealing filling layer 4 together form a water-stop structure.

[0030] As one of the specific implementation methods, as shown in the attached specification Figure 2 As shown, the water stop joint body 32 includes a first pipe section, a second pipe section and a conical pipe section connecting the two pipe sections. The first pipe section is connected to the inner pipe 2, and the second pipe section serves as an external pipe interface 31. The water stop joint 3 is an integrated structure, and at least one groove is formed on the outside of the water stop joint body 32, which can enhance the connection reliability between the water stop joint 3 and the sealing filling layer 4.

[0031] In an optimized implementation manner, the first water-stop ring 32 is interference-fitted with the outer pipe 2 , and the first water-stop ring 33 can seal the filling cavity between the inner pipe 2 and the outer pipe 1 , thereby facilitating the construction of the sealing filling layer 4 .

[0032] Preferably, the first water stop ring 33 is arranged at an end of the water stop ring body 32 away from the inner pipe 2 .

[0033] Preferably, the sealing filling layer 4 can be made of concrete, rubber, clay, etc. In this embodiment, the sealing filling layer 4 is made of high-strength and high-sealing mortar concrete mixed with asbestos cement.

[0034] In an optimized implementation method, the outer pipe 1 is preferably a steel pipe, which has certain strength and rigidity and can protect the inner pipe 2 and water stop 3 inside.

[0035] In an optimized implementation manner, a second water-stop ring 11 is mounted on the outer wall of the outer pipe 1 . The second water-stop ring 11 is a steel water-stop ring, and the second water-stop ring 11 is welded to the outer pipe 1 .

[0036] Preferably, the second water-stop ring 11 is provided in the middle of the outer pipe 1 .

[0037] In an optimized implementation manner, the inner pipe 2 is preferably a PVC pipe, and the water stop 3 is preferably a PVC water stop.

[0038] In an optimized implementation manner, the inner pipe 2 and the outer pipe 1 are coaxially arranged to ensure that the spacing between the inner pipe 2 and the outer pipe 1 is the same or close. After filling the sealing filling layer 4, the sealing and water-stopping effect is better.

[0039] Example 2

[0040] The present invention also provides a basement exterior wall structure, comprising a wall body and a pre-buried sleeve embedded in the wall body, wherein the pre-buried sleeve is the pre-buried sleeve described in Example 1, and each of the external pipe interfaces 31 is connected to an external pipe.

[0041] Preferably, the length of the outer pipe is set according to the thickness of the wall, and the length of the outer pipe 1 is equal to the thickness of the wall. The construction process of the basement exterior wall is to fix the embedded sleeve prefabricated in the factory on the basement steel bar, and the prefabricated sleeve is located between the inner and outer formwork. Concrete is poured to form the wall. After the concrete solidifies, the inner and outer formwork are removed, and the external pipe is installed on the external pipe interface 31 of the embedded sleeve. The construction of the basement exterior wall is completed, and the basement exterior wall is free of blocking in the later stage, which can greatly shorten the on-site construction period, avoid the influence of rainwater during the construction process, and improve construction efficiency.

[0042] To optimize the implementation, a protective layer can be installed at the connection between the external pipe and the water-stop 3 to ensure reliable and airtight connection. Specifically, the connection between the external pipe and the water-stop 3 is located inside the external pipe 1. A filling layer can be installed within the filling cavity outside the water-stop 3 to provide a seal and protection for the connection between the external pipe and the water-stop 3. The filling layer can be made of a rubber layer or a high-strength, high-sealing mortar concrete mixed with asbestos cement.

[0043] To prevent the concrete pouring process from affecting the interior of the external pipes, pipe caps can be used to temporarily seal the water stop joints. Once the basement exterior wall construction is complete, the pipe caps can be removed. The installation and removal of pipe caps are simple and convenient, significantly saving labor and construction time costs associated with temporary sealing and removal of formal sealing.
