Their main function is to effectively drain excess water in the soil, improve the stability of the foundation, and prevent problems such as soil softening and settlement caused by water accumulation.
[0003] The structural design of traditional drainage boards is relatively simple. A geotextile layer is laid above the drainage board for filtration, but the geotextile layer lacks sufficient compressive capacity and stability, making it difficult to adapt to complex and changeable engineering environments.
[0004] This application provides a long - term composite drainage board. Utility Model Content

A geotextile layer is laid above the drainage board for filtration, but the geotextile layer lacks sufficient compressive capacity and stability, making it difficult to adapt to complex and changeable engineering environments.
[0006] To achieve the above object, this application provides the following technical solution: A long - term composite drainage board includes a drainage board body. The top surface of the drainage board body is covered with geotextile, and the top surface of the geotextile is covered with a composite layer. The composite layer includes polyester fiber and nylon. Both the polyester fiber and nylon are located on the top surface of the geotextile, and the polyester fibers are woven with each other. A number of groups of drainage holes are opened at the top of the drainage board body, and a reinforcement layer is fixedly installed inside the geotextile.
[0007] By adopting the above technical solution, impurities in the water are filtered by the composite layer and the geotextile to prevent soil particles or impurities from entering the drainage board body. Water enters the drainage holes through the geotextile and is discharged through the drainage holes. At the same time, since the composite layer is woven by polyester fiber and nylon, this layer has good tensile resistance, which complements the geotextile and is beneficial to enhancing the wear resistance and tear resistance of the geotextile. The reinforcement layer is fixed inside the geotextile, thereby improving the durability of the geotextile and being beneficial to adapting to different environments and engineering requirements.
[0008] As a preferred technical solution of this application, the material of the reinforcement layer is composite fiber, and the reinforcement layer is a grid structure.
[0009] By adopting the above technical solution, since the strengthening layer is a grid-shaped composite fiber structure, an overall strengthening effect is formed, which is beneficial to improving the compressive capacity of the geotextile.
[0010] As a preferred technical solution of the present application, an anti-corrosion coating is applied to the outer surface of the composite layer.
[0011] By adopting the above technical solution, the influence of the humid environment on the composite layer is reduced through the anti-corrosion coating, which is beneficial to improving the weather resistance and service life of the composite layer.
[0012] As a preferred technical solution of the present application, both the drainage plate body and the composite layer are thermally fused to the geotextile.
[0013] By adopting the above technical solution, since both the drainage plate body and the composite layer are thermally fused to the geotextile, it is beneficial to improve the connection strength between the drainage plate body and the composite layer and the geotextile.
[0014] As a preferred technical solution of the present application, a plurality of groups of anti-slip strips are fixedly installed at the bottom of the drainage plate body, and the plurality of groups of anti-slip strips are evenly distributed along the bottom surface of the drainage plate body.
[0015] By adopting the above technical solution, the friction between the drainage plate body and the soil is increased through the anti-slip strips, preventing the drainage plate body from sliding during use, improving the overall stability, and further enhancing the stability of the slope.
[0016] As a preferred technical solution of the present application, the cross-section of the drainage hole is trapezoidal, the small-mouth end of the drainage hole is located on the upper surface of the drainage plate body, and the large-mouth end of the drainage hole is located on the lower surface of the drainage plate body.
[0017] By adopting the above technical solution, since the cross-section of the drainage hole is trapezoidal, it is beneficial to adapt to the smooth flow of water under different pressure conditions, and the geotextile can still maintain good drainage performance even when it is under pressure, thus ensuring the long-term stability of the slope.
[0018] The beneficial effects of the present application:
[0019] 1. The impurities in the moisture are filtered by the composite layer and the geotextile, preventing soil particles or impurities from entering the drainage plate body. The moisture enters the drainage hole through the geotextile and is discharged through the drainage hole. At the same time, since the composite layer is woven from polyester fiber and nylon, this layer has good tensile resistance, complements the geotextile, is beneficial to enhancing the wear resistance and tear resistance of the geotextile, and is fixed inside the geotextile through the strengthening layer, thereby improving the durability of the geotextile and being beneficial to adapting to different environments and engineering requirements.

[0027] Referring to Figures 1-3 , a long-acting composite drainage plate includes a drainage plate body 1. The top surface of the drainage plate body 1 is covered with a geotextile 2. The top surface of the geotextile 2 is covered with a composite layer 3. The composite layer 3 includes a polyester fiber 301 and a nylon 302. Both the polyester fiber 301 and the nylon 302 are located on the top surface of the geotextile 2, and the polyester fiber 301 is woven with the polyester fiber 301. A plurality of groups of drainage holes 4 are opened at the top of the drainage plate body 1. A reinforcing layer 5 is fixedly installed inside the geotextile 2; an anti-corrosion coating is applied on the outer surface of the composite layer 3.
[0028] The impurities in the water are filtered through the composite layer 3 and the geotextile 2 to prevent soil particles or impurities from entering the drainage plate body 1. The water enters the drainage holes 4 through the geotextile 2 and is discharged through the drainage holes 4. At the same time, since the composite layer 3 is woven by the polyester fiber 301 and the nylon 302, the layer has good tensile resistance in use, which complements the geotextile 2 and is beneficial to enhancing the wear resistance and tear resistance of the geotextile 2. The reinforcing layer 5 is fixed inside the geotextile 2, thereby improving the durability of the geotextile 2 and being beneficial to adapting to different environments and engineering requirements; the anti-corrosion coating reduces the influence of the humid environment on the composite layer 3, which is beneficial to improving the weather resistance and service life of the composite layer 3.
[0029] Referring to Figures 2-4 , the material of the reinforcement layer 5 is composite fiber, and the reinforcement layer 5 is a grid structure; both the drainage plate body 1 and the composite layer 3 are thermally melted and connected to the geotextile 2; the cross-section of the drainage hole 4 is trapezoidal, and the small-mouth end of the drainage hole 4 is located on the upper surface of the drainage plate body 1, and the large-mouth end of the drainage hole 4 is located on the lower surface of the drainage plate body 1;
[0030] Since the reinforcement layer 5 is a grid-shaped composite fiber structure, an overall strengthening effect is formed, which is beneficial to improving the compressive capacity of the geotextile 2; since both the drainage plate body 1 and the composite layer 3 are thermally melted and connected to the geotextile 2, it is beneficial to improve the connection strength between the drainage plate body 1 and the composite layer 3 and the geotextile 2; since the cross-section of the drainage hole 4 is trapezoidal, it is beneficial to adapt to the smooth flow of water under different pressure conditions, and even when the geotextile 2 is under pressure, it can still maintain good drainage performance, thus ensuring the long-term stability of the slope.
[0031] Referring to Figure 1 , a plurality of groups of anti-slip strips 6 are fixedly installed at the bottom of the drainage plate body 1, and the plurality of groups of anti-slip strips 6 are evenly distributed along the bottom surface of the drainage plate body 1; the anti-slip strips 6 are used to increase the friction between the drainage plate body 1 and the soil, prevent the drainage plate body 1 from sliding during use, improve the overall stability, and thus further enhance the stability of the slope.
[0032] Working principle: The impurities in the water are filtered by the composite layer 3 and the geotextile 2 to prevent soil particles or impurities from entering the drainage plate body 1. The water enters the drainage hole 4 through the geotextile 2 and is discharged through the drainage hole 4. At the same time, since the composite layer 3 is woven by polyester fiber 301 and nylon 302, the layer has good tensile resistance and complements the geotextile 2, which is beneficial to enhancing the wear resistance and tear resistance of the geotextile 2. The reinforcement layer 5 is fixed inside the geotextile 2, thereby improving the durability of the geotextile 2, which is beneficial to adapting to different environments and engineering requirements. Since the reinforcement layer 5 is a grid-shaped composite fiber structure, an overall strengthening effect is formed, which is beneficial to improving the compressive capacity of the geotextile 2;
[0033] Among them, the anti-corrosion coating reduces the influence of the humid environment on the composite layer 3, which is beneficial to improving the weather resistance and service life of the composite layer 3. Since both the drainage plate body 1 and the composite layer 3 are thermally melted and connected to the geotextile 2, it is beneficial to improve the connection strength between the drainage plate body 1 and the composite layer 3 and the geotextile 2;
[0034] At the same time, the anti-slip strips 6 are used to increase the friction between the drainage plate body 1 and the soil, prevent the drainage plate body 1 from sliding during use, improve the overall stability, and thus further enhance the stability of the slope;
[0035] In addition, the cross-section of the drain hole 4 is trapezoidal, which is beneficial to adapt to the smooth flow of water under different pressure conditions. Even when the geotextile 2 is under pressure, it can still maintain good drainage performance, thus ensuring the long-term stability of the slope.
