Description

Technical Field

[0001] The utility model relates to the field of basement waterproof structures, in particular to a basement water seepage prevention structure. Background Art

[0002] Basements, spaces hidden deep beneath the ground, host a variety of functions and uses, making them an integral part of urban life. They cleverly expand a building's usable area, particularly in urban environments where land resources are scarce. Basements are a valuable tool for improving space utilization. From common underground parking lots, offering convenient parking solutions to home basement renovations like conversions into home theaters, gyms, or wine cellars, basements are becoming increasingly important spaces for enhancing quality of life.

[0003] Because basements are located underground, they often face groundwater leakage, which can easily lead to dampness, mold, and even compromise structural safety. Traditional waterproofing measures typically involve laying waterproof membranes or applying waterproof coatings under the baseboard. While these can prevent groundwater infiltration to a certain extent, they struggle to completely drain the accumulated water beneath the baseboard, making it prone to loosening and floating. Utility Model Content

[0004] The purpose of the utility model is to provide a basement water seepage prevention structure, aiming to improve the problem that traditional waterproof measures are difficult to completely drain the accumulated water under the bottom plate and are prone to the phenomenon of the bottom plate loosening and floating.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A basement water seepage prevention structure, characterized in that it comprises a hydrophobic layer, the hydrophobic layer is laid on a foundation, a plurality of water collecting troughs are provided on the hydrophobic layer, a mesh filter layer is provided on the side wall of the water collecting trough, a sealing plate is provided on the upper cover of the water collecting trough, and a concrete cushion layer is laid on the hydrophobic layer;

[0007] The hydrophobic layer is provided with an inlet pipe and a pumping pipe, wherein the pumping pipe includes a main pumping pipe and a plurality of water pumping pipes connected to the main pumping pipe, the main pumping pipe is connected to an external drainage pump room, the plurality of water pumping pipes correspond one-to-one to the water collecting tank, and pass through one side wall of the water collecting tank to communicate with the inside of the water collecting tank; the water inlet pipe includes a main inlet pipe and a plurality of water inlet pipes connected to the main inlet pipe, the main water inlet pipe is connected to an external water pump, the plurality of water inlet pipes correspond one-to-one to the water collecting tank, and pass through the other side wall of the water collecting tank to communicate with the inside of the water collecting tank.

[0008] Furthermore, the water inlet pipe is located at the upper part of the hydrophobic layer, and the water extraction pipe is located at the lower part of the hydrophobic layer.

[0009] Furthermore, a first filter layer and a second filter layer are laid in the hydrophobic layer. The first filter layer is laid on the water inlet pipe, and the second filter layer is laid on the water extraction pipe.

[0010] Furthermore, the pipe opening of the water inlet pipe passes through the other side wall of the water collecting tank and extends into the water collecting tank. An arc-shaped bending portion is provided at the pipe opening of the water inlet pipe.

[0011] Furthermore, the hydrophobic layer is a gravel hydrophobic layer or a crushed stone hydrophobic layer, and the thickness of the hydrophobic layer is 20-30 cm.

[0012] Furthermore, the water pumping main pipe, water pumping diversion pipe, water inlet main pipe and water inlet diversion pipe are all PVC pipes or HDPE pipes.

[0013] Furthermore, the first filter layer and the second filter layer are both non-woven filter layers or water filter plate filter layers.

[0014] Furthermore, the thickness of the concrete cushion layer is 10-15 cm.

[0015] After adopting the above technical solution, the utility model has the following advantages compared with the background technology:

[0016] 1. A mesh filter layer separates the sump and the hydrophobic layer to prevent the hydrophobic layer from sinking and causing deformation of the sump. A concrete cushion layer covers the hydrophobic layer, protecting it, the inlet and pumping pipes, and providing a smooth construction surface for subsequent construction. The pumping pipe is located within the hydrophobic layer and connected to the sump. It is used to extract seepage water from the sump and the hydrophobic layer, ensuring dryness within the hydrophobic layer and preventing the bottom plate from loosening and floating.

[0017] 2. The water inlet pipe is located in the hydrophobic layer and is connected to the water collection tank. The water inlet pipe flushes the mesh filter layer to avoid clogging of the mesh filter layer and affecting the pumping effect of the pumping pipe on the hydrophobic layer.

[0030] Example

[0031] Please refer to Figure 1-3As shown, this embodiment provides a basement anti-seepage structure, including a hydrophobic layer 1, which is laid on a foundation 7, and a plurality of water collecting troughs 11 are arranged on the hydrophobic layer 1, and a mesh filter layer 12 is arranged on the side wall of the water collecting trough 11, and a sealing plate 13 is provided on the top cover of the water collecting trough 11, and a concrete cushion layer 6 is laid on the hydrophobic layer 1. An inlet pipe 3 and a pumping pipe 2 are laid in the hydrophobic layer 1. The pumping pipe 2 includes a main pumping pipe 21 and multiple water pumping branches 22 connected to the main pumping pipe 21. The main pumping pipe 21 is connected to the external drainage pump room. The multiple water pumping branches 22 correspond one-to-one to the water collecting tank 11 and pass through one side wall of the water collecting tank 11 to communicate with the interior of the water collecting tank 11; the inlet pipe 3 includes a main inlet pipe 31 and multiple water inlet branches 32 connected to the main inlet pipe 31. The inlet pipe 31 is connected to the external water pump. The multiple water inlet branches 32 correspond one-to-one to the water collecting tank 11 and pass through the other side wall of the water collecting tank 11 to communicate with the interior of the water collecting tank 11.

[0032] In this embodiment, the main water pumping pipe 21, the water pumping pipe 22, the main water inlet pipe 31, and the water inlet pipe 32 are all PVC pipes. Similarly, the main water pumping pipe 21, the water pumping pipe 22, the main water inlet pipe 31, and the water inlet pipe 32 can also be HDPE pipes. This ensures that the main water pumping pipe 21, the water pumping pipe 22, the main water inlet pipe 31, and the water inlet pipe 32 have good pressure resistance and corrosion resistance, and prevents the main water pumping pipe 21, the water pumping pipe 22, the main water inlet pipe 31, and the water inlet pipe 32 from rupturing in the hydrophobic layer 1, which would affect the pumping and flushing effects.

[0033] The thickness of the concrete cushion layer 6 is 10-15 cm. In this embodiment, the thickness of the concrete cushion layer 6 is 12 cm. Similarly, the thickness of the concrete cushion layer 6 can also be 10 cm or 15 cm. The concrete cushion layer 6 covers the hydrophobic layer 1, protects the hydrophobic layer 1, the water inlet pipe 3, and the water pumping pipe 2, and provides a flat construction surface for subsequent construction.

[0034] Please refer to Figure 1 As shown, the mesh filter layer 12 separates the water collection tank 11 and the hydrophobic layer 1 to prevent the hydrophobic layer 1 from sinking and causing deformation of the water collection tank 11. The pumping pipe 2 is located in the hydrophobic layer 1 and is connected to the water collection tank 11. The pumping pipe 2 is used to extract the seepage water in the water collection tank 11 and the hydrophobic layer 1 to ensure the dryness of the hydrophobic layer 1 and prevent the bottom plate from loosening and floating. At the same time, the water inlet pipe 3 is located in the hydrophobic layer 1 and is connected to the water collection tank 11. The water inlet pipe 3 flushes the mesh filter layer 12 to prevent the mesh filter layer 12 from being blocked and affecting the pumping effect of the pumping pipe 2 on the hydrophobic layer 1.

[0035] In this embodiment, the water inlet pipe 3 is located above the hydrophobic layer 1, and the water pumping pipe 2 is located below the hydrophobic layer 1. The water pumping pipe 2 located below the hydrophobic layer 1 facilitates extraction of all accumulated water within the sump 11, improving the water pumping efficiency. The water inlet pipe 3 located above the hydrophobic layer 1 provides a high acceleration of the water flow entering the sump 11 through the water inlet pipe 3, thereby enhancing the flushing efficiency of the mesh filter layer 12.

[0036] In this embodiment, a first filter layer 4 and a second filter layer 5 are also laid within the hydrophobic layer 1. The first filter layer 4 is laid on the water inlet pipe 3, and the second filter layer 5 is laid on the water pumping pipe 2. The first filter layer 4 protects the water inlet pipe 3 to prevent gravel or small particles above the water inlet pipe 3 from falling during water seepage, squeezing the water inlet pipe 3 or moving it below the water inlet pipe 3, lifting the water inlet pipe 3, and easily causing the water inlet pipe 3 to rupture within the hydrophobic layer 1. The second filter layer protects the water pumping pipe 2 to prevent gravel or small particles above the water pumping pipe from falling during water seepage, squeezing the water pumping pipe 2 or moving it below the water pumping pipe 2, lifting the water pumping pipe 2, and easily causing the water pumping pipe 2 to rupture within the hydrophobic layer 1.

[0037] In this embodiment, the first filter layer 4 and the second filter layer 5 are both non-woven filter layers. Similarly, the first filter layer 4 and the second filter layer 5 can also be water filter plate filter layers.

[0038] Please refer to Figure 2 As shown, in this embodiment, the water extraction pipe 22 and the water inlet pipe 32 are respectively on the two sides corresponding to the water collection tank 11, and the mesh filter layer 12 on one side of the water extraction pipe 2 is fully flushed. Similarly, the water extraction pipe 22 and the water inlet pipe 32 can also be located on the same side of the water collection tank 11, and the mesh filter layer 12 opposite the water extraction pipe 22 is fully flushed. The positions of the water extraction pipe 22 and the water inlet pipe 32 are set according to the use requirements. Please refer to Figure 3 As shown, the outlet of the water inlet manifold 32 passes through the other sidewall of the sump 11 and extends into the sump 11. An arcuate bend 321 is provided at the outlet of the water inlet manifold 32. This arcuate bend 321 provides a spiral acceleration to the water flow entering the sump 11, causing the water flow entering the sump 11 to flush various locations of the mesh filter layer 12 in a spiral pattern, further enhancing the flushing effect of the mesh filter layer 12. After flushing is complete, the water flow in the sump 11 is extracted using the pumping pipe 2.

[0039] The hydrophobic layer 1 is a gravel hydrophobic layer 1 or a crushed stone hydrophobic layer 1, and has a thickness of 20-30 cm. In this embodiment, the thickness of the hydrophobic layer 1 is 10 cm. Similarly, the thickness of the hydrophobic layer 1 can also be 20 cm or 30 cm. The height of the hydrophobic layer 1 determines the height of the sump 11 and the diameters of the water inlet pipe 3 and the water pumping pipe 2. Setting an appropriate height of the hydrophobic layer 1 avoids excessive occupation of the basement area and provides sufficient space for the water inlet pipe 3 and the water pumping pipe 2 to ensure effective pumping and flushing.

[0040] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
