Abstract
Description
Technical Field
[0001] This application relates to the technical field of anti-seepage structures, and specifically to an anti-seepage structure for the exterior wall of a basement. Background Art
[0002] With the rapid development of modern building technology, the construction and use of basements are becoming increasingly common. Especially in high-rise buildings, large commercial complexes, and urban infrastructure, as an important functional space, the basement undertakes various functions such as parking lots, equipment rooms, and storage rooms. However, due to its special underground environment, the basement is long-term threatened by the erosion and penetration of groundwater, making waterproofing and insulation important links that cannot be ignored in the design and construction of the basement.
[0003] In the existing basement waterproofing technology, waterproof membranes, as a commonly used waterproof material, are widely used in the waterproof treatment of the exterior wall of the basement. Waterproof membranes play an important role in resisting the leakage of external rainwater and groundwater with their excellent water resistance, temperature stability, and certain mechanical strength. However, over time, it is easy for the waterproof membrane to detach from the exterior wall of the basement. The detachment of the waterproof membrane will not only reduce the waterproof performance of the basement, but also may lead to problems such as water seepage and dampness inside the wall, seriously affecting the normal use and safety of the basement.
[0004] On the other hand, the insulation performance of the exterior wall of the basement is also an important factor affecting the use effect of the basement. Since the basement is located underground and its exterior wall is isolated from the external environment, the temperature difference between indoors and outdoors will still cause condensation. When the indoor temperature is higher than the outdoor temperature, condensation water is likely to form on the surface of the wall, which will not only accelerate the aging and damage of the wall, but also may penetrate into the room through the tiny defects of the waterproof layer, resulting in problems such as dampness and mildew. Utility Model Content
[0005] Aiming at the deficiencies of the existing technology, this application provides an anti-seepage structure for the exterior wall of a basement, which has advantages such as good insulation performance, and solves the problems raised in the background art.
[0006] To achieve the above object, this application provides the following technical solution: An anti-seepage structure for the exterior wall of a basement, including an exterior wall, the bottom end of the left side of the exterior wall is set to be inclined outward, a heat preservation groove is provided at the top of the exterior wall, and a heat preservation layer is filled in the heat preservation groove;
[0007] The left side and the right side of the exterior wall are both coated with a first waterproof layer, and a second waterproof layer is bonded to the side of each of the two first waterproof layers away from each other;
[0008] A separation layer is provided on the left side of the second waterproof layer on the left side;
[0009] A drainage groove is provided at the left bottom end of the exterior wall, and the right end of the drainage groove extends below the thermal insulation layer.
[0010] Through the above solution, polyurethane waterproof coatings are applied on both the left and right sides of the exterior wall as the first waterproof layer. Its excellent waterproof effect and the characteristic of being applicable both indoors and outdoors provide a solid waterproof barrier for the basement. At the same time, the APP modified asphalt waterproof coiled material adhered to the outside of the first waterproof layer serves as the second waterproof layer. With its good elasticity and extensibility, it can effectively adapt to the minor deformation of the base surface and prevent the waterproof layer from cracking due to structural changes, further enhancing the waterproof effect. The isolation layer is formed by stacking gravel, and the tight structure formed among the gravel effectively reduces the channels for water penetration, improving the overall water isolation effect. While preventing groundwater seepage, it also reduces problems such as mildew and corrosion caused by wall dampness.
[0011] Furthermore, a drainage box is fixedly connected inside the drainage groove, and the bottom end of the drainage box is inclined.
[0012] Through the above solution, due to the inclined bottom end of the drainage box, it is convenient for water to flow out.
[0013] Furthermore, a set of equally spaced drainage seams are provided on the left side of the exterior wall.
[0014] Through the above solution, through the arrangement of the drainage seams, the downward flow of water can be achieved.
[0015] Furthermore, a set of drainage holes are provided at the left bottom end of the exterior wall and the inner bottom wall of the thermal insulation groove.
[0016] Through the above solution, through the arrangement of the drainage holes, the water in the drainage seams can enter the drainage box and be discharged.
[0017] Furthermore, both of the first waterproof layers are polyurethane waterproof coatings.
[0018] Through the above solution, since both of the first waterproof layers are polyurethane waterproof coatings, they are applicable both indoors and outdoors, with a relatively thick coating and good waterproof effect.
[0019] Furthermore, both of the second waterproof layers are APP modified asphalt waterproof coiled materials.
[0020] Through the above solution, since both of the second waterproof layers are APP modified asphalt waterproof coiled materials, they have good elasticity and extensibility and can adapt to the deformation of the base surface.
[0021] Furthermore, the thermal insulation layer is a rigid polyurethane thermal insulation material.
[0022] With the above solution, since the thermal insulation layer is made of rigid polyurethane thermal insulation material, in addition to its thermal insulation and moisture-proof properties, the rigid polyurethane thermal insulation material also has good weather resistance and durability, while ensuring the support strength of the exterior wall.
[0023] Furthermore, the partition layer is formed by stacking gravel.
[0024] With the above solution, gravel can reduce the channels for water penetration, thereby improving the overall water-proof effect.
[0025] Compared with the prior art, the technical solution of the present application has the following beneficial effects:
[0026] For the anti-seepage structure of the basement exterior wall, polyurethane waterproof coating is applied on both the left and right sides of the exterior wall as the first waterproof layer. Its excellent waterproof effect and the characteristics of being applicable both indoors and outdoors provide a solid waterproof barrier for the basement. At the same time, the APP modified asphalt waterproof coiled material bonded on the outside of the first waterproof layer as the second waterproof layer, with its good elasticity and extensibility, can effectively adapt to the minor deformation of the base surface and prevent the waterproof layer from cracking due to structural changes, further enhancing the waterproof effect. The partition layer is formed by stacking gravel, and the tight structure formed among the gravel effectively reduces the channels for water penetration and improves the overall water-proof effect. This not only prevents groundwater seepage but also reduces problems such as mildew and corrosion caused by the dampness of the wall.
[0027] For the anti-seepage structure of the basement exterior wall, the outwardly inclined shape designed at the bottom end of the left side of the exterior wall and the drainage groove, combined with the inclined setting of the drainage box, enable the water entering the wall and its surface to quickly gather and flow downward under the action of gravity, effectively avoiding the accumulation of water inside and on the surface of the wall. In addition, the setting of the drainage joint and drainage holes provides a smooth drainage channel for the water inside the wall, further improving the drainage efficiency. The rigid polyurethane thermal insulation material filled in the thermal insulation groove not only has excellent thermal insulation performance, can effectively prevent the transfer of indoor and outdoor temperatures and reduce energy consumption, but also has good moisture-proof, weather resistance and durability. At the same time, the high-strength characteristics of the rigid polyurethane also provide the necessary support force for the exterior wall, ensuring the stability and safety of the structure.

Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.
[0035] Please refer to Figure 1 、 Figure 2 and Figure 3 . A waterproof structure for the basement exterior wall in this embodiment includes an exterior wall 1. The bottom end of the left side surface of the exterior wall 1 is set to be inclined outward. A group of equally spaced drainage seams 9 are provided on the left side surface of the exterior wall 1. Through the arrangement of the drainage seams 9, the downward flow of water can be realized. A heat preservation groove 2 is provided at the top end of the exterior wall 1, and a heat preservation layer 3 is filled in the heat preservation groove 2.
[0036] Please refer to Figure 1 、 Figure 2 and Figure 3 . The left side surface and the right side surface of the exterior wall 1 are both coated with a first waterproof layer 4. A second waterproof layer 5 is bonded to the side surfaces of the two first waterproof layers 4 that are away from each other. The two first waterproof layers 4 are both polyurethane waterproof coatings. Since the first waterproof layer 4 is a polyurethane waterproof coating, it can be used indoors and outdoors, has a relatively thick coating, and has a good waterproof effect.
[0037] Please refer to Figure 1 、 Figure 2 and Figure 3 . A partition layer 6 is provided on the left side surface of the second waterproof layer 5 on the left side. The partition layer 6 is formed by stacking gravel. Through the gravel, the channels for water penetration can be reduced, thereby improving the overall water isolation effect. The two second waterproof layers 5 are both APP modified asphalt waterproof coiled materials. Since the second waterproof layer 5 is an APP modified asphalt waterproof coiled material, it has good elasticity and extensibility and can adapt to the deformation of the base surface.
[0038] Please refer to Figure 1 、 Figure 3 and Figure 4, a drainage groove 7 is provided at the left bottom end of the outer wall 1, and the right end of the drainage groove 7 extends below the thermal insulation layer 3. A drainage box 8 is fixedly connected inside the drainage groove 7, and the bottom end of the drainage box 8 is inclined. By the inclined setting of the bottom end of the drainage box 8, it is convenient for water to flow out. The thermal insulation layer 3 is made of rigid polyurethane thermal insulation material. By using rigid polyurethane thermal insulation material for the thermal insulation layer 3, in addition to the thermal insulation and moisture-proof performance, the rigid polyurethane thermal insulation material also has good weather resistance and durability, and at the same time ensures the support strength of the outer wall 1.
[0039] Please refer to Figure 1 , Figure 2 and Figure 3 , a set of drainage holes 10 are provided at the left bottom end of the left side surface of the outer wall 1 and the inner bottom wall of the thermal insulation groove 2. Through the arrangement of the drainage holes 10, the water in the drainage joint 9 can be drained into the drainage box 8 and discharged.
[0040] In an anti-seepage structure of a basement outer wall in this embodiment, by applying polyurethane waterproof coating on both the left and right side surfaces of the outer wall 1 as the first waterproof layer 4, its excellent waterproof effect and the characteristics of being applicable both indoors and outdoors provide a solid waterproof barrier for the basement. At the same time, the APP modified asphalt waterproof coiled material bonded on the outside of the first waterproof layer 4 as the second waterproof layer 5, with its good elasticity and extensibility, can effectively adapt to the minor deformation of the base surface and prevent the waterproof layer from cracking due to structural changes, further enhancing the waterproof effect. The isolation layer 6 is formed by stacking gravel, and the tight structure formed between the gravel effectively reduces the channels for water penetration and improves the overall water isolation effect. While preventing groundwater seepage, it also reduces problems such as mildew and corrosion caused by the dampness of the wall. The outwardly inclined shape designed at the left bottom end of the outer wall 1 and the provided drainage groove 7, combined with the inclined setting of the drainage box 8, enable the water entering the wall and its surface to quickly gather and flow downward under the action of gravity, effectively avoiding the accumulation of water inside and on the surface of the wall. In addition, the arrangement of the drainage joint 9 and the drainage holes 10 provides a smooth drainage channel for the water inside the wall, further improving the drainage efficiency. The rigid polyurethane thermal insulation material filled in the thermal insulation groove 2 not only has excellent thermal insulation performance, can effectively prevent the transfer of indoor and outdoor temperatures and reduce energy consumption, but also has good moisture-proof, weather resistance and durability. At the same time, the high-strength characteristics of rigid polyurethane also provide the necessary support force for the outer wall 1, ensuring the stability and safety of the structure.
[0041] The working principle of the above embodiments is as follows: The isolation layer 6 is located outside the second waterproof layer 5 and is formed by stacking gravel. The tight structure formed between the gravel can effectively reduce the channels for water penetration and improve the overall waterproof effect. The second waterproof layer 5 has good elasticity and extensibility, can adapt to the minor deformation of the wall, and avoid the damage of the waterproof layer caused by structural changes. At the same time, the weather resistance and aging resistance of the APP modified bitumen waterproof coiled material also ensure the stability of the second waterproof layer 5. The first waterproof layer 4 uses polyurethane waterproof coating, which has the characteristics of being applicable both indoors and outdoors and has a relatively thick coating, capable of forming a dense waterproof film to effectively block the penetration of water from the wall surface. The high elasticity and durability of the polyurethane waterproof coating ensure the long-term effectiveness of the waterproof layer. The left bottom end of the outer wall 1 is designed to be inclined outward and a drainage groove 7 is provided, so that the accumulated water on the wall surface can quickly gather into the drainage groove 7, avoiding the retention and penetration of water on the wall surface. A drainage box 8 is fixed inside the drainage groove 7, and the bottom end of the drainage box 8 is inclined. When water enters the drainage groove 7, it will quickly flow out along the inclined surface of the drainage box 8, further improving the drainage efficiency. The rigid polyurethane thermal insulation material filled in the thermal insulation groove 2 has excellent thermal insulation performance. This material can effectively prevent the transfer of indoor and outdoor temperatures and reduce energy consumption. At the same time, the high strength characteristics of the rigid polyurethane also provide the necessary supporting force for the outer wall 1, ensuring the stability of the structure.
