Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a pipeline installation anti-leakage structure. Background Art

[0002] In building spaces, kitchens and bathrooms are key water-using areas, which usually involve the installation of various types of pipes. In order to avoid leakage of pipes during use and thus affect the anti-leakage structure of the pipe installation, waterproofing measures are usually taken around the pipe openings and at the inner corners of the pipe installation anti-leakage structure. A common waterproofing measure is to apply waterproof paint around the pipe openings and at the inner corners of the wall.

[0003] However, the areas around the pipe openings and the inner corners of the walls are mostly right-angled. Applying waterproof coating at these locations is prone to uneven application, and leakage is likely to occur even after application. Related technologies have proposed a construction process for arc-smoothing at the inner corners of waterproof floors. Before applying waterproof coating at the inner corners, cement mortar is first used to perform arc-smoothing treatment at the locations, and then waterproof coating is applied, thus avoiding the problem of uneven application.

[0004] However, when cement mortar is applied artificially, pores or cracks will appear on its surface. When waterproof coating is applied directly to cement mortar, these pores or cracks are not effectively sealed. When the pipeline leaks, water may penetrate into the waterproof coating through these pores, gradually eroding the waterproof structure, and thus causing leakage hazards. In addition, this construction process does not involve protective measures for the waterproof coating. The waterproof coating is exposed to the external environment for a long time. As the use time increases, the surface of the waterproof coating is prone to cracking, and the waterproof effect is therefore reduced. Utility Model Content

[0028] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0029] In indoor buildings, areas like kitchens and bathrooms are key water-using areas and often involve the installation of pipes. In order to provide a certain degree of protection for the pipes to prevent serious leakage in the later stages of their use, waterproof coatings are usually applied to the roots of the pipes after installation. However, it is difficult to achieve complete sealing of the pipe roots when applying waterproof coatings, resulting in poor indoor waterproofing effects.

[0030] To improve the leakage of pipes and enhance the waterproofing effect of water-using areas, such as Figure 1-Figure 2 As shown, the utility model provides a pipeline installation anti-leakage structure, including a pipeline protection structure 1 and a bearing wall 2 arranged at an angle and connected to each other, wherein the pipeline is arranged in the pipeline protection structure 1. In order to improve the leakage at the root of the pipeline, the pipeline installation anti-leakage structure provided by the utility model also includes a waterproof structure 3. The waterproof structure 3 is arranged at the connection between the pipeline protection structure 1 and the bearing wall 2. In order to improve the connection strength between the waterproof structure 3 and the two, before setting the waterproof structure 3, it is necessary to first clean and polish the surfaces of the pipeline protection structure 1 and the bearing wall 2, and then sprinkle water to wet the surfaces of the two, to ensure that the subsequent waterproof structure 3 can be laid evenly and firmly connected to the pipeline protection structure 1 and the bearing wall 2.

[0031] The pipe protection structure 1 may include a pipe wrapper 11 and an installation wall 12, both of which can wrap the indoor pipe structure, such as a drain pipe or an exhaust pipe, and both can seal the internal pipes. On the basis of not occupying too much indoor space, it also improves the overall aesthetic effect of the interior after installation. However, the material used to make the pipe wrapper 11 is mostly not concrete. When it is clamped between the installation wall 12 and the load-bearing wall 2, the integrity of the connection between the pipe wrapper 11 and the two is poor. In order to improve the leakage at the root of the pipe, a waterproof structure 3 can be provided at the inner corner between the pipe wrapper 11 and the load-bearing wall 2 to improve the waterproof level of the root of the pipe.

[0032] Specifically, if Figure 1 and Figure 2 As shown, the waterproof structure 3 includes a rigid transition block 31, an anti-seepage adhesive layer 32, a flexible waterproof layer 33 and a waterproof protective layer 34, wherein the rigid transition block 31 is arranged at the bottom layer, and then the anti-seepage adhesive layer 32, the flexible waterproof layer 33 and the waterproof protective layer 34 are arranged in sequence from bottom to top. During the construction process, there is a gap between the pipeline protection structure 1 and the bearing wall 2. The rigid transition block 31 can fill the gap between the two and enhance the sealing effect of the pipeline root. The rigid transition block 31 can use anti-cracking mortar or waterproof mortar as a filling material. The rigid transition block 31 is provided with a transition curved surface 311. Compared with setting a right-angle shape, setting the transition curved surface 311 can facilitate the uniform application of the anti-seepage adhesive layer 32 and improve the connection effect between the rigid transition block 31 and the upper anti-seepage adhesive layer 32. The transition surface 311 can be an arc surface to ensure that when the rigid transition block 31 is subjected to force, the transition surface 311 can evenly disperse the stress to the arc surface, thereby avoiding cracking of the anti-seepage adhesive layer 32 or the flexible waterproof layer 33 due to stress concentration at a certain sharp corner. The radius of the arc surface is not less than 50 mm to improve the stress dispersion effect of the transition surface 311 and reduce the operation difficulty of construction personnel.

[0033] Due to the uniformity of the coating and the porosity of the coating material, gaps or cracks may exist within the rigid transition block 31. To fill these gaps or cracks, an impermeable adhesive layer 32 is provided above the rigid transition block 31. The layer comprises a first connecting portion 321, a second connecting portion 322, and a third connecting portion 323, which are respectively connected to the pipe protection structure 1, the load-bearing wall 2, and the transition curved surface 311. This improves the integrity of the connection between the impermeable adhesive layer 32 and the pipe protection structure 1, the load-bearing wall 2, and the rigid transition block 31. To meet the waterproofing standards of water-using areas, the connection length between the first connecting portion 321 and the pipe protection structure 1 is at least 300 mm, and the connection length between the second connecting portion 322 and the load-bearing wall 2 is at least 300 mm. This ensures that indoor water use does not affect the pipe protection structure 1 and the load-bearing wall 2, preventing water from seeping into surrounding rooms. The impermeable adhesive layer 32 can be made of a water-tight filling material with high impermeability and excellent bonding ability, achieving both waterproofing and bonding effects.

[0034] The flexible waterproof layer 33 is bonded to the top of the anti-seepage adhesive layer 32, and the top of the flexible waterproof layer 33 is covered with a waterproof protective layer 34. The flexible waterproof layer 33 will not crack easily and is firmly connected to the surrounding pipeline protection structure 1 and the supporting wall 2. Compared with the prior art in which the flexible waterproof layer 33 is directly set above the rigid transition block 31, the pipeline installation anti-leakage structure proposed by the utility model is provided with an anti-seepage adhesive layer 32 between the flexible waterproof layer 33 and the rigid transition block 31, which can effectively improve the integrity and connection stability of the three, extend the service life of the waterproof structure 3, and effectively improve the waterproof level of the root position of the pipeline. The upper provision of the waterproof protective layer 34 can also prevent the flexible waterproof layer 33 from cracking due to long-term exposure to the external environment.

[0035] In one embodiment, the flexible waterproof layer 33 includes a flexible fiber layer 331 and a waterproof coating layer 332 covering the flexible fiber layer 331. The flexible fiber layer 331 is filled with a matrix reinforcement material such as a chemical fiber non-woven fabric or a glass fiber mesh, and has excellent flexibility and tensile strength. When the rigid transition block 31 is impacted by external forces and cracks or deforms, the flexible fiber layer 331, relying on its own toughness, prevents the cracks from expanding, thereby ensuring the structural integrity and waterproofing effectiveness of the waterproof structure 3. The waterproof coating layer 332 can be filled with a waterproof coating such as a polyurethane waterproof coating or a polymer cement waterproof coating. For example, polymer cement waterproof coating is a two-component waterproof coating composed of a synthetic polymer emulsion and various inorganic materials composed of cement, quartz powder, and additives. It combines the high elasticity of synthetic polymer materials with the durability of inorganic materials. The waterproof coating layer 332, together with the flexible fiber layer 331, the anti-seepage adhesive layer 32, and the rigid transition block 31, forms a waterproof barrier, effectively sealing the root of the pipe.

[0036] During the construction process, in order to improve the waterproof effect of the waterproof coating layer 332, at least three layers of waterproof coating layers 332 can be set to ensure that the waterproof coating is evenly covered on the flexible fiber layer 331, thereby improving the structural density of the waterproof coating layer 332. In order to ensure the waterproof effect of the waterproof coating layer 332, the total thickness of at least three layers of waterproof coating layers 332 should be no less than 1.5 mm to effectively prevent moisture penetration and improve its own structural strength.

[0037] The waterproof protective layer 34 covers the flexible waterproof layer 33. To improve the overall sealing performance of the waterproof structure 3, the waterproof protective layer 34 can include a first sealing portion 341, a second sealing portion 342, and a covering portion 343. The first sealing portion 341 is connected to the pipe protection structure 1, the second sealing portion 342 is connected to the load-bearing wall 2, and the covering portion 343 is connected to the flexible waterproof layer 33. The first sealing portion 341 and the second sealing portion 342 are both used to seal the anti-seepage adhesive layer 32 and the flexible waterproof layer 33 to prevent the indoor humid environment from affecting the waterproof effect of the anti-seepage adhesive layer 32 and the flexible waterproof layer 33. To simplify the operation difficulty for construction personnel, rounded corners can be provided at the positions of the first sealing portion 341 and the second sealing portion 342 to optimize the stress dispersion effect when the waterproof structure 3 is subjected to external force impact. The overall thickness of the waterproof protective layer 34 should be no less than 15 mm to enhance the overall structural stability of the waterproof structure 3 and reduce the risk of leakage due to deformation of the various structural parts. The pipeline installation anti-leakage structure proposed by the utility model has high structural integrity, is equipped with multiple waterproof measures, has a high waterproof grade, and can effectively improve the leakage situation at the root of the pipeline.

Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation methods here.
