Abstract
Description
Technical Field
[0001] This application relates to the field of building construction, specifically to a waterproof construction structure for a side wall sleeve. Background Technology
[0002] For residential projects, leak prevention is a crucial aspect that residents are particularly concerned about. However, leaks in underground garages are common, and this problem persists even after the houses are handed over. When residential buildings are equipped with multiple functions, such as a five-constant system (fixed temperature, humidity, and electrical system), a large number of through-wall pipes accumulate on the basement exterior walls, making the external waterproofing a weak point and significantly increasing the risk of leaks. Using traditional methods, the inherent hardness and thickness of the waterproofing membrane makes it difficult to tightly wrap the dense cluster of pipes, thus creating a potential leakage hazard. Therefore, solving the quality problems of waterproofing construction for structures with dense clusters of pipes protruding from the walls is crucial to ensuring the quality of high-quality residential projects and achieving truly "good houses."
[0003] A common practice for waterproofing through-wall sleeves in basement exterior walls is to use SBS modified bitumen waterproof membrane for encapsulation. During implementation, the waterproof membrane is first cut to an appropriate size and evenly sliced on one side so that it can be wrapped around the outside of the sleeve, serving as an additional waterproof layer. When the exterior wall waterproofing layer reaches the sleeve, another layer of waterproof membrane is placed on top of this additional layer, making the pipe waterproofing system an integral part of the exterior wall waterproofing.
[0004] When using traditional waterproof membranes to waterproof the casing, the membrane wrapping the pipe needs to be cut. This means that each cut adds an overlap. The membrane itself has a certain rigidity and thickness, making it difficult to achieve a tight seal at the overlaps, thus creating a risk of leakage. Furthermore, the compaction of the backfill soil can deform the casing, tearing the waterproof membrane and easily damaging the waterproofing system. Additionally, the slow settlement of the backfill soil can also cause similar problems. Utility Model Content
[0005] The purpose of this utility model is to provide a waterproof construction structure for the side wall sleeve of the structure, in order to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: A waterproof construction method for a wall sleeve in a structural structure is characterized by: a waterproof reinforced concrete structural side wall and a pipe group disposed on the waterproof reinforced concrete structural side wall. The pipe group includes several through-wall sleeves and pipes passing through and partially supported within the through-wall sleeves. A waterproof layer is provided on the end of the through-wall sleeve extending out of the water-facing side of the waterproof reinforced concrete structural side wall. The waterproof layer includes a two-step, four-coat waterproof layer between the through-wall sleeves and a two-step, four-coat waterproof layer at the pipe root. The two-step, four-coat waterproof layer at the pipe root is simultaneously applied to the outer wall of the through-wall sleeve and the outer wall of the wall on the water-facing side. Furthermore, a paint waterproof layer and a roll waterproof layer are sequentially disposed on the outer side of the two-step, four-coat waterproof layer at the pipe root located on the outer wall.
[0007] More preferably, the through-wall sleeve extends at least 100mm out of the wall on both sides.
[0008] Furthermore, a water-stop ring is welded and fixed to the outer wall of the middle part of the through-wall sleeve, and the water-stop ring is welded and fixed to the steel mesh frame inside the side wall of the waterproof reinforced concrete structure.
[0009] Furthermore, the two-step four-coat waterproof layer between pipes and the two-step four-coat waterproof layer at the pipe root have the same structure, with a thickness of ≥3mm, and both include two layers of non-woven fabric and four layers of waterproof coating.
[0010] Furthermore, the space inside the wall sleeve and outside the pipe is provided with an internal sealing layer, the total width of which is the same as the total length of the wall sleeve.
[0011] Furthermore, the two-step, four-coat waterproof layer at the pipe root extends from the outermost through-wall sleeve and extends at least 250mm towards the outer wall of the water-facing side.
[0012] In addition, a non-curing rubber asphalt waterproof coating sealant is provided between the roll waterproof layer and the root of the outermost through-wall sleeve.
[0013] More preferably, the two-step four-coat waterproof layer between pipes and the two-step four-coat waterproof layer at the pipe root are laid in the order of paint layer, non-woven fabric layer, paint layer, paint layer, non-woven fabric layer, and paint layer. The non-woven fabric used in the non-woven fabric layer has a specification of 40g / ㎡ and a total width of ≥250mm. Compared with the prior art, this utility model has the following features and beneficial effects: This application, while strictly ensuring the quality of waterproofing construction, reduces the difficulty of on-site operations by scientifically optimizing the construction process, creating more favorable implementation conditions for construction organization, and can effectively promote the application of coating waterproofing systems in densely sleeved areas, thus having a positive social benefit for the technological upgrading of the industry.
[0014] The technology employed in this application simplifies the construction process, effectively saving labor costs. Simultaneously, by using waterproof coatings as the core waterproofing method at key points, it combines material compatibility with ease of operation, significantly improving construction efficiency and generating economic benefits. This technology also reduces the frequency of using roll-on spray guns, lowering operational safety risks from the outset.
[0015] This application addresses the construction challenge of densely packed pipes penetrating walls by innovatively employing a "two-layer, four-coat method," successfully resolving issues such as poor adhesion of the waterproof layer and limitations in roll material application in traditional processes. This not only improves the reliability of waterproofing projects but also expands the application scenarios of coating-based waterproofing systems, providing a referable technical solution for similar projects.

[0018] The embodiments described herein are specific implementations of this utility model, used to illustrate the concept of this utility model. They are all illustrative and exemplary, and should not be construed as limiting the implementation methods or scope of this utility model. In addition to the embodiments described herein, those skilled in the art can employ other obvious technical solutions based on the content disclosed in the claims and specification of this application. These technical solutions include those that make any obvious substitutions and modifications to the embodiments described herein.
[0019] Example 1 A waterproof construction method for a side wall sleeve, such as Figure 1As shown, the structure includes a waterproof reinforced concrete side wall 1 and a pipe group 2 installed on the waterproof reinforced concrete side wall 1. The pipe group 2 includes several through-wall sleeves 21 and pipes 22 passing through and partially supported within the through-wall sleeves 21. A waterproof layer 3 is provided on the end of the through-wall sleeve 21 extending outward from the water-facing side of the waterproof reinforced concrete side wall 1. The waterproof layer 3 includes a two-step four-coat waterproof layer 31 between the through-wall sleeves 21 and a two-step four-coat waterproof layer 32 at the pipe root of the through-wall sleeve 21. The two-step four-coat waterproof layer 32 at the pipe root is applied to both the outer wall of the through-wall sleeve 21 and the outer wall of the water-facing side of the wall. Furthermore, a paint waterproof layer 4 and a roll waterproof layer 5 are sequentially provided on the outer side of the two-step four-coat waterproof layer 32 at the pipe root on the outer wall of the wall. The through-wall sleeve 21 extends outward from the wall on both sides by at least 100mm. A water-stop ring 23 is welded and fixed to the outer wall of the middle part of the through-wall sleeve 21. The water-stop ring 23 is connected to the waterproof reinforced concrete side wall 1. The steel mesh reinforcement within the side wall 1 is welded and fixed. The two-step, four-coat waterproof layer 31 between pipes and the two-step, four-coat waterproof layer 32 at the pipe roots have the same structure and a thickness ≥3mm. Both include two layers of non-woven fabric and four layers of waterproof coating. An internal sealing layer 6 is also provided in the space inside the wall sleeve 21 and outside the pipe 22. The total width of the internal sealing layer 6 is the same as the total length of the wall sleeve 21. The two-step, four-coat waterproof layer 32 at the pipe roots is applied to the outermost side (the outermost side is the outermost side relative to the pipe group). The outer wall of the through-wall sleeve 21 extends at least 250mm beyond the outer wall of the water-facing side. A non-curing rubber asphalt waterproof coating sealing layer 7 is provided between the roll waterproof layer 5 and the root of the outermost through-wall sleeve 21. The two-step four-coat waterproof layer 31 between pipes and the two-step four-coat waterproof layer 32 at the root of the pipe are laid in the order of coating layer, non-woven fabric layer, coating layer, coating layer, non-woven fabric layer, and coating layer. The non-woven fabric used in the non-woven fabric layer has a specification of 40g / ㎡ and a total width ≥250mm.
[0020] Example 2 In this embodiment, when the sleeve extends beyond the outer surface of the wall, the sleeve is first treated with the "two-layer cloth and four-coat method". Then, the waterproof membrane is applied to the base of the sleeve, and finally, the non-curing rubber asphalt waterproof coating is used to seal it tightly. After the internal pipe is installed, the gap inside the sleeve needs to be sealed. This is done by sealing the outside of the anti-seepage mortar and the inside of the anti-seepage mortar with hemp rope. A reliable waterproof system can be formed through the above methods. Both the two-step four-coat waterproof layer between pipes and the two-step four-coat waterproof layer at the pipe root adopt the two-layer fabric and four-coat method. The "two-layer fabric and four-coat method" means that first, a high-viscosity anti-slip rubber asphalt waterproof coating is applied around the pipe (total thickness of waterproof coating ≥3mm, coating radius ≥250mm, extending to the pipe body ≥100mm), the first layer of non-woven fabric (specification 40g / ㎡, total width ≥250mm, laying width around the opening ≥150mm, overlap width ≥100mm) is pressed in, then the second layer of waterproof coating is applied, and after the coating is completely dry, the third layer of waterproof coating is applied, the second layer of non-woven fabric is pressed in, and finally the fourth layer of waterproof coating is applied.
