Description

Technical Field

[0001] This application relates to the field of exterior wall technology, specifically to a basement exterior wall structure. Background Technology

[0002] A basement is a space in a building that is below the outdoor ground level. Buildings can improve the utilization of land by including basements.

[0003] An existing patent (publication number: CN218479207U) discloses a basement exterior wall structure, which includes an exterior wall body. A drainage ditch is installed on the side of the exterior wall body closest to the external soil layer. A drainage pipe is connected to the bottom of the drainage ditch. A cover plate is installed at the opening of the drainage ditch, positioned above the opening of the drainage pipe. A filter plate is installed at the end of the cover plate closest to the drainage pipe. The filter plate spans and is installed between the two walls of the drainage ditch along the direction of rainwater flow. A sliding groove seat is installed on the wall of the drainage ditch, on the side of the filter plate away from the drainage pipe. A baffle plate for covering or opening the filter plate is slidably connected within the sliding groove seat. This application has the effect of reducing the impact of debris blockage in the drainage pipe on drainage flow, thus preventing rainwater leakage from the basement exterior wall.

[0004] In heavy rain, the above structure requires users to go outdoors to pull the baffle. If the user forgets, water can easily accumulate on the outside of the wall, making it less practical. In addition, the filter plate needs to be cleaned regularly, which increases the user's labor intensity and makes the operation more cumbersome. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a basement exterior wall structure that has advantages such as good seepage prevention and drainage, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this application provides the following technical solution: a basement exterior wall structure, including a foundation soil layer and a wall, wherein the bottom end of the wall is set as a right-angled trapezoid, the bottom slope of the wall is located outdoors, a drainage box is fixedly connected to the bottom slope of the wall, the right side of the drainage box is parallel to the bottom slope of the wall, and a set of distributed permeable holes are opened on the right side of the drainage box;

[0007] The drainage tank is internally fixedly connected with a set of reinforcing ribs. The wall includes a main body, the exterior of which is provided with a waterproof layer and an exterior decorative layer in sequence, and the interior of which is provided with an insulation layer and an interior decorative layer in sequence.

[0008] The above-described design, with its drainage box and distributed permeable holes on the sloping bottom of the wall, effectively collects and discharges water that seeps into the soil, avoiding direct contact between water and the wall and reducing damage caused by water erosion. Simultaneously, the internal reinforcing ribs of the drainage box enhance its mechanical strength, prevent deformation, and ensure long-term stability. Furthermore, the gravel filter layer between the foundation soil and the drainage box effectively blocks impurities and particles in the soil, preventing blockage of the permeable holes and ensuring smooth operation of the drainage system. The sloping bottom wall of the drainage box, fixedly connected to a drainage pipe, ensures that accumulated water in the drainage box can be quickly and smoothly discharged into the municipal drainage system. A check valve installed in the drainage pipe effectively prevents backflow of water from the municipal drainage system. The right-angled trapezoidal shape of the wall's bottom, located outdoors, not only improves the wall's mechanical strength but also enhances its stability.

[0009] Furthermore, the seepage-proof layer is a polymer waterproof membrane.

[0010] The above scheme and setup can effectively prevent groundwater from seeping into the walls, ensuring the dryness and safety of the basement interior.

[0011] Furthermore, the outer coating is a stone-like paint or ceramic tile.

[0012] The above solutions and settings can enhance the aesthetics and durability of the wall, while also resisting the effects of harsh outdoor weather.

[0013] Furthermore, the insulation layer is a polystyrene foam board.

[0014] The above solutions and settings can effectively improve the thermal insulation performance of the walls and reduce energy consumption inside the basement.

[0015] Furthermore, a filter layer, which is gravel, is provided between the foundation soil layer and the drainage tank.

[0016] The above solution effectively prevents impurities and particles in the soil from entering the drainage tank through the filtering effect of gravel, thus avoiding blockage of the permeable holes and ensuring the smooth operation of the drainage system.

[0017] Furthermore, the inner bottom wall of the drainage tank is designed as an inclined surface, and a drainage pipe is fixedly connected to the inner bottom wall of the drainage tank, which is connected to the external municipal drainage pipeline.

[0018] The above scheme and setup ensure that the water in the drainage tank can be quickly and smoothly drained into the municipal drainage system through the drainage pipe, thus preventing the water from posing a potential threat to the basement.

[0019] Furthermore, a check valve is installed inside the drain pipe.

[0020] The above solution can prevent water from municipal drainage pipes from flowing back into the basement drainage system under certain circumstances, thereby protecting the safety and hygiene of the basement.

[0021] Furthermore, the interior layer is made of environmentally friendly latex paint.

[0022] The above solutions, through the application of environmentally friendly latex paint or wallpaper, can provide a beautiful, comfortable, and healthy indoor environment that is easy to clean and maintain, meeting the decoration and usage needs of the basement interior space.

[0023] Furthermore, the main body is a reinforced concrete structure.

[0024] The above solution possesses high strength, high stability, and good durability, capable of withstanding the pressure of external soil and groundwater in the basement, while ensuring the overall stability and safety of the wall.

[0025] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0026] This basement exterior wall structure effectively collects and discharges water seeping into the soil through a drainage box and distributed permeable holes located on the sloping bottom of the wall. This avoids direct contact between water and the wall, reducing damage caused by water erosion. Simultaneously, the internal reinforcing ribs of the drainage box enhance its mechanical strength, prevent deformation, and ensure long-term stability. Furthermore, the gravel filter layer between the foundation soil and the drainage box effectively blocks impurities and particles in the soil, preventing blockage of the permeable holes and ensuring smooth operation of the drainage system. The inner bottom wall of the drainage box is sloping and fixedly connected to a drainage pipe, ensuring that accumulated water in the drainage box can be quickly and smoothly discharged into the municipal drainage system. A check valve installed in the drainage pipe effectively prevents backflow of water from the municipal drainage system. The bottom of the wall is designed as a right-angled trapezoid and located outdoors; this design not only improves the mechanical strength of the wall but also enhances its stability.

A drainage box 3 is fixedly connected to the sloped bottom end of the wall 2. The right side of the drainage box 3 is parallel to the sloped bottom end of the wall 2. A set of distributed permeable holes 4 are provided on the right side of the drainage box 3. Through the permeable holes 4, the infiltrated water can be discharged, preventing water in the soil from directly contacting the wall 2.

[0035] Please see Figure 1 , Figure 2 and Figure 3 The drainage tank 3 is internally fixed with a set of reinforcing ribs 5 to improve its mechanical strength and prevent deformation. The wall 2 includes a main body 201. The exterior surface of the main body 201 is sequentially provided with a waterproof layer 202 and an exterior decorative layer 203. The interior surface of the main body 201 is sequentially provided with an insulation layer 204 and an interior decorative layer 205. The waterproof layer 202 is a high-polymer waterproof membrane. Through the above-mentioned arrangement, groundwater can be effectively isolated from the penetration of the wall 2, ensuring the dryness and safety of the basement. The exterior decorative layer 203 is a stone-like paint or ceramic tile. Through the above-mentioned arrangement, the aesthetics and durability of the wall 2 can be enhanced, while resisting outdoor... Due to the influence of harsh climate, the insulation layer 204 is made of polystyrene foam board. This design effectively improves the thermal insulation performance of wall 2 and reduces energy consumption inside the basement. The interior layer 205 is made of environmentally friendly latex paint. The application of environmentally friendly latex paint or wallpaper can provide a beautiful, comfortable and healthy indoor environment, while being easy to clean and maintain, meeting the decoration and usage needs of the basement interior space. The main body 201 is a reinforced concrete structure with high strength, high stability and good durability. It can withstand the pressure of the soil and groundwater outside the basement, while ensuring the overall stability and safety of wall 2.

[0036] Please see Figure 1 , Figure 2 and Figure 4 A filter layer 6, composed of gravel, is installed between the foundation soil layer 1 and the drainage tank 3. Through the filtering effect of the gravel, impurities and particles in the soil can be effectively blocked from entering the drainage tank 3, thereby preventing the permeable holes 4 from being blocked and ensuring the smooth operation of the drainage system. The inner bottom wall of the drainage tank 3 is designed as an inclined surface, and a drainage pipe 7 is fixedly connected to the inner bottom wall of the drainage tank 3. The drainage pipe 7 is connected to the external municipal drainage pipe 7. Through the above settings, it can be ensured that the water in the drainage tank 3 can be quickly and smoothly discharged into the municipal drainage pipe 7 through the drainage pipe 7, avoiding potential threats to the basement from the water accumulation. A check valve 8 is installed inside the drainage pipe 7 to prevent water in the municipal drainage pipe 7 from backflowing into the basement drainage system under certain circumstances, thereby protecting the safety and hygiene of the basement.

[0037] In this embodiment, a basement exterior wall structure utilizes a drainage box 3 and distributed permeable holes 4 located on the sloping bottom surface of the wall 2. This effectively collects and discharges water that has seeped into the soil, preventing direct contact between water and the wall 2 and reducing damage caused by water erosion. Simultaneously, the internal reinforcing ribs 5 of the drainage box 3 enhance its mechanical strength, prevent deformation, and ensure long-term stability. Furthermore, the gravel filter layer 6 between the foundation soil layer 1 and the drainage box 3 effectively blocks impurities and particles in the soil, preventing blockage of the permeable holes 4 and ensuring smooth operation of the drainage system. The inner bottom wall of the drainage box 3 is sloping and is fixedly connected to a drainage pipe 7, ensuring that accumulated water in the drainage box 3 can be quickly and smoothly discharged into the municipal drainage pipe 7. A check valve 8 installed in the drainage pipe 7 effectively prevents backflow of water from the municipal drainage pipe 7. The bottom of the wall 2 is designed as a right-angled trapezoid and located outdoors. This design not only improves the mechanical strength of the wall 2 but also enhances its stability.

[0038] The working principle of the above embodiment is as follows: The bottom end of the wall 2 is designed as a right-angled trapezoid and located outdoors, which not only enhances the stability of the wall 2 but also improves its mechanical strength, enabling it to better withstand the pressure of external soil and groundwater. A drainage box 3 is fixedly connected to the bottom slope of the wall 2. The right side of the drainage box 3 is parallel to the bottom slope of the wall 2. A set of distributed permeable holes 4 are opened on the right side of the drainage box 3. These permeable holes 4 can collect and drain water that seeps into the soil, avoiding direct contact between water and the wall 2, thereby reducing the damage to the wall 2 caused by water erosion. A set of reinforcing ribs 5 are fixedly connected inside the drainage box 3. The reinforcing bar 5 improves the mechanical strength of the drainage tank 3, preventing deformation during use. Meanwhile, a gravel filter layer 6 is provided between the base soil layer 1 and the drainage tank 3. This filter layer 6 can effectively block impurities and particles in the soil from entering the drainage tank 3, preventing the permeable holes 4 from being blocked and ensuring the smooth operation of the drainage system. The inner bottom wall of the drainage tank 3 is set as an inclined surface and is fixedly connected to the drainage pipe 7. The accumulated water will flow quickly into the drainage pipe 7 along the inclined surface and be discharged into the municipal drainage pipe 7 through the drainage pipe 7. In addition, a check valve 8 is installed in the drainage pipe 7. This check valve 8 can prevent water in the municipal drainage pipe 7 from flowing back in under certain circumstances, such as pipe repair or backflow.
