Description

Technical Field

[0001] This application relates to the field of pipeline structures, and in particular to a waterproof structure for pipeline penetrations through walls during the renovation of old residential communities. Background Technology

[0002] Some old residential areas suffer from years of disrepair, with rusted water pipes causing frequent leaks, blockages, and even backflow of dirty water, severely impacting residents' quality of life. Therefore, water pipe renovation is one of the key projects in the renovation of old residential areas.

[0003] Existing waterproofing repair solutions for pipe penetrations through walls on the market are either complex to construct, requiring extensive damage to the wall structure and consuming significant manpower, resources, and time, making them unsuitable for older residential communities where strict requirements on construction noise levels are in place; or they offer poor waterproofing, failing to fundamentally solve long-term leakage problems and leading to repeated repairs. Therefore, developing a waterproofing structure for pipe penetrations through walls that is suitable for the renovation of older residential communities, easy to construct, and provides long-lasting and reliable waterproofing is of great significance. Utility Model Content

[0004] To improve the waterproofing of the connection between pipes and walls, this application provides a waterproofing structure for pipe penetrations through walls in the renovation of old residential areas.

[0005] The waterproofing structure for pipe penetrations through walls in the renovation of old residential communities provided in this application adopts the following technical solution:

[0006] A waterproof structure for pipe penetration points in old residential communities includes pipes, which are installed at the wall penetration points.

[0007] A water-stop ring is attached to the outside of the pipe and is integrally formed with the pipe. The top of the water-stop ring is higher than the wall, and the bottom of the water-stop ring is lower than the wall.

[0008] A sleeve is provided outside the water-stop ring, with the top of the sleeve flush with the top of the water-stop ring and the bottom of the sleeve flush with the bottom of the water-stop ring.

[0009] The base layer, wherein the base layer is disposed between the water-stop ring and the sleeve; and,

[0010] A waterproof layer is provided between the water-stop ring and the sleeve, and the waterproof layer is provided on the outside of the base layer.

[0011] By adopting the above technical solution, the water-stop ring is integrally formed with the pipe and surrounds the outside of the pipe. Since the top of the water-stop ring is higher than the wall and the bottom is lower than the wall, when water flows into contact with the junction of the wall and the pipe, the water-stop ring can increase the path of water penetration. The sleeve is set outside the water-stop ring, with its top and bottom flush with the water-stop ring. The sleeve protects the water-stop ring from direct damage by external factors, ensuring the integrity and waterproof performance of the water-stop ring. On the other hand, the sleeve and the water-stop ring form a relatively closed space, providing a stable structural foundation for the installation of the base layer and the waterproof layer. The base layer is set between the water-stop ring and the sleeve, mainly serving the functions of filling and reinforcement. The waterproof layer is located outside the base layer, directly in contact with the external environment, and can effectively prevent water penetration.

[0012] Preferably, the waterproof structure further includes a sealing layer, which is disposed between the water-stop ring and the sleeve, and between the base layer and the waterproof layer.

[0013] By adopting the above technical solution, the sealing layer is located between the base layer and the waterproof layer. It is made of a material with good sealing performance, which can fill the tiny pores and cracks on the surface of the base layer and form a continuous and dense physical barrier. This can effectively prevent water from penetrating directly in liquid form and prevent water from passing through the gap between the base layer and the waterproof layer.

[0014] Preferably, the waterproof structure further includes a reinforcing layer, which is disposed between the water-stop ring and the sleeve, and between the sealing layer and the waterproof layer.

[0015] By adopting the above technical solution, the base layer fills the gap between the water-stop ring and the sleeve, making the interior of the waterproof structure more compact and reducing the risk of leakage caused by gaps. In addition, the base layer provides a flat and strong adhesion base for the sealing layer, ensuring that the sealing layer can be firmly bonded to it, thereby ensuring the stability of the overall waterproof structure.

[0016] Preferably, the waterproof structure further includes a plurality of first protrusions and a plurality of second protrusions, wherein the plurality of first protrusions are disposed on the surface of the water-stop ring and are in contact with the sealing layer, and the plurality of second protrusions are disposed on the surface of the sleeve and are in contact with the sealing layer.

[0017] By adopting the above technical solution, the first protrusion is set on the surface of the water-stop ring, and the second protrusion is set on the surface of the sleeve, both of which are in contact with the sealing layer. These protrusions increase the contact area between the water-stop ring and the sleeve and the sealing layer. The larger the contact area, the stronger the adhesion between the sealing layer and the water-stop ring and the sleeve, allowing the sealing layer to adhere more firmly between them, making it less prone to displacement or detachment, thereby improving the sealing performance of the entire waterproof structure.

[0018] Preferably, the waterproof structure further includes a plurality of water guiding channels, which are disposed on the surface of the waterproof layer, are arranged around the periphery of the pipe, and extend radially along the pipe.

[0019] By adopting the above technical solution, when rainwater or other moisture falls on the surface of the waterproof layer, the water channel provides a clear direction for the flow of water. The water will flow along the direction of the water channel and be quickly drained away from the surface of the waterproof layer, instead of accumulating on the waterproof layer, thus reducing the waterproofing pressure on the waterproof layer.

[0020] Preferably, the outlet of the water guide channel is connected to the drainage system.

[0021] By adopting the above technical solution, since the outlet of the water guide channel is connected to the drainage system, water can be directly discharged into the drainage system, realizing rapid and efficient drainage from the surface of the waterproof layer to the drainage system, and avoiding the accumulation of water on the surface of the waterproof layer.

[0022] Preferably, the waterproof structure further includes a heating wire, which is disposed inside the water-stop ring and is connected to a power source. The heating wire is used to heat the pipe.

[0023] By adopting the above technical solution, the heating wire is placed inside the water-stop ring and connected to the power supply. When the ambient temperature is low, especially in the cold winter, the heating wire can heat the pipe by turning on the power, which can prevent the water in the pipe from freezing. Because water expands in volume after freezing, it may cause the pipe to crack and thus damage the entire waterproof structure. At the same time, heating can also prevent the water around the water-stop ring from freezing, avoiding gaps between the water-stop ring and the pipe or wall due to ice expansion, thus ensuring the waterproof effect of the water-stop ring.

[0024] Preferably, the heating wire is spiral-shaped.

[0025] By adopting the above technical solution, the spiral heating wire is wrapped around the water-stop ring. Compared with the straight heating wire, its distribution range is wider, and it can heat the pipe and water-stop ring more evenly when energized.

[0026] In summary, this application includes the following beneficial technical effects:

[0027] The water-stop ring is integrally formed with the pipe, reducing the risk of waterproofing failure due to loosening, corrosion and other problems at the connection. The sleeve protects the water-stop ring and internal structure, as well as reinforces the base layer. Through the multi-layer waterproofing design of the water-stop ring, base layer and waterproof layer, the waterproofing capability at the pipe penetration point is improved.

[0032] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0033] This utility model provides a waterproof structure for pipe penetrations through walls during the renovation of old residential communities. The structure is as follows: Figure 1 - Figure 2 As shown, it includes pipe 1, water-stop ring 3, sleeve 4, base layer 5, and waterproof layer 51.

[0034] Pipe 1 is installed at point 2 in the wall.

[0035] The water-stop ring 3 is connected to the outside of the pipe 1. The water-stop ring 3 is integrally formed with the pipe 1. The top of the water-stop ring 3 is higher than the wall 2, and the bottom of the water-stop ring 3 is lower than the wall 2.

[0036] The sleeve 4 is located outside the water-stop ring 3. The top of the sleeve 4 is flush with the top of the water-stop ring 3, and the bottom of the sleeve 4 is flush with the bottom of the water-stop ring 3.

[0037] The base layer 5 is located between the water-stop ring 3 and the sleeve 4. The base layer 5 is made of cement mortar or oil hemp.

[0038] The waterproof layer 51 is located between the water-stop ring 3 and the sleeve 4. The waterproof layer 51 is located on the outside of the base layer 5. The waterproof layer 51 is a waterproof coating.

[0039] In use, the water-stop ring 3 is integrally formed with the pipe 1 and surrounds the outside of the pipe 1. Since the top of the water-stop ring 3 is higher than the wall 2 and the bottom is lower than the wall 2, when water flows into contact with the junction of the wall 2 and the pipe 1, the water-stop ring 3 can increase the path of water penetration. The sleeve 4 is set outside the water-stop ring 3, and its top and bottom are flush with the water-stop ring 3. The sleeve 4 protects the water-stop ring 3 on the one hand, preventing external factors from directly damaging the water-stop ring 3 and ensuring the integrity and waterproof performance of the water-stop ring 3. On the other hand, the sleeve 4 and the water-stop ring 3 form a relatively closed space, providing a stable structural foundation for the setting of the base layer 5 and the waterproof layer 51. The base layer 5 is set between the water-stop ring 3 and the sleeve 4, mainly playing the role of filling and reinforcement. The waterproof layer 51 is located outside the base layer 5 and is in direct contact with the external environment, which can effectively prevent water penetration.

[0040] In this utility model, the water-stop ring 3 is integrally formed with the pipe 1, which reduces the risk of waterproof failure caused by loosening, corrosion and other problems at the connection. The sleeve 4 protects the water-stop ring 3 and the internal structure, and the base layer 5 reinforces it. Through the multi-layer waterproof design of the water-stop ring 3, the base layer 5 and the waterproof layer 51, the waterproof capability of the pipe 1 at the wall penetration point is improved.

[0041] To improve sealing, please refer to Figure 1 In a preferred embodiment, the waterproof structure further includes a sealing layer 52, which is a sealant. The sealing layer 52 is disposed between the water-stop ring 3 and the sleeve 4, and between the base layer 5 and the waterproof layer 51.

[0042] When in use, the sealing layer 52 is located between the base layer 5 and the waterproof layer 51. It is made of a material with good sealing performance, which can fill the tiny pores and cracks on the surface of the base layer 5 to form a continuous and dense physical barrier. This can effectively prevent water from penetrating directly in liquid form and prevent water from passing through the gap between the base layer 5 and the waterproof layer 51.

[0043] To increase strength, please refer to Figure 1 In a preferred embodiment, the waterproof structure further includes a reinforcing layer 53, which is a fiberglass mesh fabric. The reinforcing layer 53 is disposed between the water-stop ring 3 and the sleeve 4, and between the sealing layer 52 and the waterproof layer 51.

[0044] During use, the base layer 5 fills the gap between the water-stop ring 3 and the sleeve 4, making the interior of the waterproof structure more compact and reducing the risk of leakage caused by gaps. In addition, the base layer 5 provides a flat and strong adhesion base for the sealing layer 52, ensuring that the sealing layer 52 can be firmly bonded to it, thereby ensuring the stability of the overall waterproof structure.

[0045] To enhance the connection strength between the water-stop ring 3, the sleeve 4, and the sealing layer 52, please refer to... Figure 1 In a preferred embodiment, the waterproof structure further includes a plurality of first protrusions 31 and a plurality of second protrusions 41. The plurality of first protrusions 31 are disposed on the surface of the water-stop ring 3 and are in contact with the sealing layer 52. The plurality of second protrusions 41 are disposed on the surface of the sleeve 4 and are in contact with the sealing layer 52.

[0046] In use, the first protrusion 31 is disposed on the surface of the water-stop ring 3, and the second protrusion 41 is disposed on the surface of the sleeve 4, both of which are in contact with the sealing layer 52. These protrusions increase the contact area between the water-stop ring 3 and the sleeve 4 and the sealing layer 52. The larger the contact area, the stronger the adhesion between the sealing layer 52 and the water-stop ring 3 and the sleeve 4, allowing the sealing layer 52 to adhere more firmly between them, making it less prone to displacement or detachment, thereby improving the sealing performance of the entire waterproof structure.

[0047] To ensure timely removal of moisture from the surface of the waterproof layer 51, please refer to... Figure 1 In a preferred embodiment, the waterproof structure further includes a plurality of water guide channels 6, which are disposed on the surface of the waterproof layer 51, are arranged around the periphery of the pipe 1, and extend radially along the pipe 1.

[0048] When in use, when rainwater or other moisture falls on the surface of the waterproof layer 51, the water channel 6 provides a clear direction for the flow of moisture. The moisture will flow along the direction of the water channel 6 and be quickly drained away from the surface of the waterproof layer 51, instead of accumulating on the waterproof layer 51, thus reducing the waterproof pressure on the waterproof layer 51.

[0049] To further improve drainage efficiency, please refer to Figure 1 In a preferred embodiment, the outlet of the water guide channel 6 is connected to the drainage system.

[0050] When in use, since the outlet of the water guide channel 6 is connected to the drainage system, water can be directly discharged into the drainage system, realizing rapid and efficient drainage from the surface of the waterproof layer 51 to the drainage system, and preventing water from accumulating on the surface of the waterproof layer 51.

[0051] To reduce the likelihood of icing inside pipe 1, please refer to... Figure 1 In a preferred embodiment, the waterproof structure further includes a heating wire disposed inside the water-stop ring 3. The heating wire is connected to a power source and is used to heat the pipe 1.

[0052] During use, the heating wire is installed inside the water-stop ring 3 and connected to the power supply. When the ambient temperature is low, especially in the cold winter, the heating wire can heat the pipe 1 by turning on the power, which can prevent the water in the pipe 1 from freezing. Because the water expands in volume after freezing, it may cause the pipe 1 to crack, thereby damaging the entire waterproof structure. At the same time, heating can also prevent the water around the water-stop ring 3 from freezing, avoiding the gap between the water-stop ring 3 and the pipe 1 or the wall 2 due to the expansion of ice, thus ensuring the waterproof effect of the water-stop ring 3.

[0053] To improve heating uniformity, please refer to... Figure 1 In a preferred embodiment, the heating wire is spiral-shaped.

[0054] When in use, the spiral heating wire is wrapped around the water-stop ring 3. Compared with the straight heating wire, its distribution range is wider, and it can heat the pipe 1 and the water-stop ring 3 more evenly when energized.

[0055] The implementation principle of the waterproof structure at the pipe penetration point in the old residential area according to the embodiment of this application is as follows: the water-stop ring 3 is integrally formed with the pipe 1 and surrounds the outside of the pipe 1. Since the top of the water-stop ring 3 is higher than the wall 2 and the bottom is lower than the wall 2, when water flows into contact with the junction of the wall 2 and the pipe 1, the water-stop ring 3 can increase the path of water penetration. The sleeve 4 is set outside the water-stop ring 3, and its top and bottom are flush with the water-stop ring 3. The sleeve 4 plays a protective role for the water-stop ring 3, preventing external factors from directly damaging the water-stop ring 3 and ensuring the integrity and waterproof performance of the water-stop ring 3. On the other hand, the sleeve 4 and the water-stop ring 3 form a relatively closed space, which provides a stable structural foundation for the setting of the base layer 5 and the waterproof layer 51. The base layer 5 is set between the water-stop ring 3 and the sleeve 4, and mainly plays a role in filling and reinforcing. The waterproof layer 51 is located outside the base layer 5 and is in direct contact with the external environment, which can effectively prevent water penetration.

[0056] 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.
