Description

Technical Field

[0001] The utility model relates to the technical field of landfill anti-seepage, in particular to a composite anti-seepage structure for a solid waste landfill. Background Art

[0002] In existing landfill projects, the types of anti-seepage structures at the bottom of landfills are mainly divided into three types: single-layer lining anti-seepage structure, double-layer lining anti-seepage structure, and composite lining anti-seepage structure. In the current landfill with a composite lining anti-seepage structure, there are problems that the compacted clay layer is only laid on the bottom foundation layer of the reservoir, has no anti-seepage effect on the toe of the slope and the reservoir slope, and the reliability of the lap joint with the bentonite carpet is average.

[0003] In the prior art CN208604642U, the clay layer extension section formed by extending the compacted clay layer along the surface of the reservoir slope foundation layer can not only form an anti-seepage barrier on the reservoir slope foundation layer, effectively enhance the "reservoir basin" effect of the compacted clay layer, but also increase the reliability of the connection between the bentonite carpet and the compacted clay layer, thereby improving the anti-seepage safety of the anti-seepage structure at the bottom of the landfill.

[0004] This structure isolates sewage from the soil, but the sewage still remains on the anti-seepage structure, and there is still a risk that the sewage accumulated on this structure for a long time will penetrate into the soil. Content of the Utility Model

[0005] The purpose of the utility model is to provide a composite anti-seepage structure for a solid waste landfill, which solves the problem that this structure isolates sewage from the soil, but the sewage still remains on the anti-seepage structure, and there is still a risk that the sewage accumulated on this structure for a long time will penetrate into the soil.

[0006] To achieve the above purpose, the utility model provides a composite anti-seepage structure for a solid waste landfill, including a foundation layer, a protective layer, and a drainage mechanism. The drainage mechanism includes two fixing blocks, a first filter plate, two clamping blocks, and a baffle. The protective layer has grooves and a plurality of water diversion grooves. The fixing blocks have clamping grooves. The protective layer is fixedly connected to the foundation layer and is located above the foundation layer. The two fixing blocks are fixedly connected to the protective layer and are located on both sides of the groove. The two clamping blocks are respectively fixedly connected to both ends of the first filter plate and are located below the first filter plate. The two clamping blocks are respectively slidably connected to the two fixing blocks and are respectively located in the two clamping grooves, and the first filter plate is located in the groove. The baffle is fixedly connected to the protective layer and is located on one side in the groove.

[0007] Wherein, the drainage mechanism further includes a plurality of support rods. Both ends of the plurality of support rods are respectively fixedly connected to the two fixing blocks and are located below the first filter plate.

[0008] Among them, the drainage mechanism further includes a diversion pipe, which is fixedly connected to the protective layer and is located in the groove.

[0009] Among them, the composite anti-seepage structure of the solid waste landfill further includes a filtering mechanism, which is arranged on the protective layer and the diversion pipe and is located in the groove.

[0010] Among them, the filtering mechanism includes a second filter plate, two mounting blocks and two mounting clamping blocks. The two mounting blocks are respectively fixedly connected to both ends of the second filter plate. The two mounting clamping blocks are fixedly connected to the protective layer and are located at both ends of the groove. The two mounting blocks are respectively slidably connected to the two mounting clamping blocks.

[0011] In a composite anti-seepage structure of a solid waste landfill of the present utility model, the protective layer is fixedly connected to the base layer and is located above the base layer. The two fixing blocks are fixedly connected to the protective layer and are located on both sides of the groove. The two clamping blocks are respectively fixedly connected to both ends of the first filter plate and are located below the first filter plate. The two clamping blocks are respectively slidably connected to the two fixing blocks and are respectively located in the two card slots, and the first filter plate is located in the groove. The baffle is fixedly connected to the protective layer and is located on one side in the groove. When using this device during the anti-seepage of the landfill, the garbage is piled on the protective layer and the first filter plate. The sewage generated by the garbage will slowly flow downward. The sewage flows onto the protective layer. Due to the slight angle between the protective layer and the horizontal plane, the sewage flows through the plurality of water diversion grooves on the protective layer to the first filter plate and the groove. The sewage passes through the first filter plate and is filtered into the groove. The garbage is isolated above the groove by the first filter plate. Due to the certain inclination angle of the groove, after the sewage enters the groove, the sewage flows to the lower side of the groove and flows out of the groove. The sewage will not accumulate on the protective layer for a long time, thereby reducing the risk of sewage entering the soil. Description of the Drawings

[0020] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present utility model, and should not be construed as limiting the present utility model.

[0021] The first embodiment of the present application is as follows:

[0022] Please refer to Figures 1 - 4 , Figure 1 It is a schematic structural diagram of the overall composite anti-seepage structure of the solid waste landfill of the first embodiment of the present utility model, Figure 2 It is Figure 1 An enlarged view of part A in Figure 3 It is a schematic structural diagram of the overall composite anti-seepage structure of the solid waste landfill of the first embodiment of the present utility model in another direction, Figure 4 It is a cross-sectional view of the overall composite anti-seepage structure of the solid waste landfill of the first embodiment of the present utility model.

[0023] The present utility model provides a composite anti-seepage structure for a solid waste landfill, including a base layer 101, a protective layer 102 and a drainage mechanism. The drainage mechanism includes two fixed blocks 111, a first filter plate 103, a plurality of support rods 104, a drainage pipe 105, two clamping blocks 106 and a baffle plate 109. The protective layer 102 has a groove 110 and a plurality of water diversion troughs 108. The fixed block 111 has a card slot 107. Through the foregoing solution, the problem that the structure separates sewage from soil, but the sewage still stays on the anti-seepage structure, and there is still a risk of the sewage seeping into the soil after long-term accumulation on the structure is solved.

[0024] In this specific embodiment, the protective layer 102 is fixedly connected to the base layer 101 and is located above the base layer 101. The two fixing blocks 111 are fixedly connected to the protective layer 102 and are located on both sides of the groove 110. The two clamping blocks 106 are respectively fixedly connected to both ends of the first filter plate 103 and are located below the first filter plate 103. The two clamping blocks 106 are respectively slidably connected to the two fixing blocks 111 and are respectively located in the two clamping grooves 107, and the first filter plate 103 is located in the groove 110. The baffle 109 is fixedly connected to the protective layer 102 and is located on one side in the groove 110. When using this device during landfill anti-seepage, garbage is piled on the protective layer 102 and the first filter plate 103, and the sewage generated by the garbage will slowly flow downward. The sewage flows onto the protective layer 102. Since the protective layer 102 has a slight angle with the horizontal plane, the sewage flows through the plurality of water guiding grooves 108 on the protective layer 102 to the first filter plate 103 and the groove 110. The sewage passes through the first filter plate 103 and filters into the groove 110. The garbage is isolated above the groove 110 by the first filter plate 103. Since the groove 110 has a certain inclination angle, after the sewage enters the groove 110, the sewage flows to the lower side of the groove 110 and flows out of the groove 110. The sewage will not accumulate on the protective layer 102 for a long time, thereby reducing the risk of sewage entering the soil.

[0025] Among them, both ends of the multiple support rods 104 are fixedly connected to the two fixed blocks 111 respectively and are located below the first filter plate 103. The diversion pipe 105 is fixedly connected to the protective layer 102 and is located within the groove 110. When using this device during landfill anti-seepage, the two clamping blocks 106 are respectively clamped into the two clamping slots 107 to complete the installation of the first filter plate 103. Meanwhile, when cleaning the first filter plate 103, only the two clamping blocks 106 need to be respectively pulled out from the two clamping slots 107. The installation and disassembly of the first filter plate 103 are relatively convenient, increasing the convenience of this device. Garbage is piled on the protective layer 102 and the first filter plate 103. The first filter plate 103 bears part of the gravity of the garbage. The multiple support rods 104 support the first filter plate 103 to ensure that when the garbage presses on the first filter plate 103, the first filter plate 103 maintains a stable state, increasing the stability of this device. The sewage generated by the garbage will slowly flow downward. The sewage flows onto the protective layer 102. Due to the slight angle between the protective layer 102 and the horizontal plane, the sewage flows through the multiple water diversion grooves 108 on the protective layer 102 to the first filter plate 103 and the groove 110. The sewage passes through the first filter plate 103 and filters into the diversion pipe 105 within the groove 110. The garbage is isolated above the groove 110 by the first filter plate 103. Due to the certain inclination angle of the groove 110 and the diversion pipe 105, after the sewage enters the groove 110, the sewage flows to the lower side of the groove 110 and flows out of the groove 110. The diversion pipe 105 is made of HDPE material, playing an anti-seepage role for the sewage. The sewage will not accumulate on the protective layer 102 for a long time, thereby reducing the risk of sewage entering the soil.

[0026] When using the present utility model for anti-seepage of solid waste landfills, the two clamping blocks 106 are respectively clamped into the two clamping grooves 107 to complete the installation of the first filter plate 103. At the same time, when cleaning the first filter plate 103, only need to pull out the two clamping blocks 106 from the two clamping grooves 107 respectively. The installation and disassembly of the first filter plate 103 are relatively convenient, increasing the convenience of the device. The garbage is piled on the protective layer 102 and the first filter plate 103. The first filter plate 103 bears part of the gravity of the garbage. The multiple support rods 104 support the first filter plate 103 to ensure that when the garbage presses on the first filter plate 103, the first filter plate 103 maintains a stable state, increasing the stability of the device. The sewage generated by the garbage will slowly flow downward. The sewage flows onto the protective layer 102. Since the protective layer 102 has a slight angle with the horizontal plane, the sewage flows through the multiple water diversion grooves 108 on the protective layer 102 to the first filter plate 103 and the groove 110. The sewage passes through the first filter plate 103 and filters into the diversion pipe 105 in the groove 110. The garbage is isolated above the groove 110 by the first filter plate 103. Since the groove 110 and the diversion pipe 105 have a certain inclination angle, after the sewage enters the groove 110, the sewage flows to the lower side of the groove 110 and flows out of the groove 110. The sewage will not accumulate on the protective layer 102 for a long time, thereby reducing the risk of sewage entering the soil.

[0027] The second embodiment of this application is as follows:

[0028] Please refer to Figures 5 - 6 , Figure 5 which is the overall structural schematic diagram of the second embodiment of the composite anti-seepage structure of the solid waste landfill of the present utility model. Figure 6 It is Figure 5 The enlarged view at position B in. On the basis of the first embodiment, the composite anti-seepage structure of the solid waste landfill in this embodiment further includes a filtering mechanism. The filtering mechanism is arranged on the protective layer 102 and the diversion pipe 105 and is located in the groove 110. The filtering mechanism includes a second filter plate 201, two mounting blocks 202 and two mounting clamping blocks 203.

[0029] The two mounting blocks 202 are respectively fixedly connected to both ends of the second filter plate 201. The two mounting clamp blocks 203 are fixedly connected to the protective layer 102 and are located at both ends of the groove 110. The two mounting blocks 202 are respectively slidably connected to the two mounting clamp blocks 203. After the sewage enters the diversion pipe 105, the second filter plate 201 is located on the lower side of the diversion pipe 105, and the sewage flows out from the second filter plate 201. The second filter plate 201 filters the fine garbage in the sewage again, making the process of discharging the sewage more refined. When replacing the second filter plate 201, only need to pull up the second filter plate 201, and the two mounting blocks 202 are respectively pulled out from the two mounting clamp blocks 203. The processes of installing and disassembling the second filter plate 201 are both relatively convenient.

[0030] The above disclosure is only one or more preferred embodiments of the present application, and cannot be used to limit the scope of rights of the present application. Those of ordinary skill in the art can understand all or part of the processes of implementing the above embodiments, and the equivalent changes made according to the claims of the present application still fall within the scope covered by the present application.
