[0002] The geomembrane impermeable layer protection structure of constructed wetlands is a geosynthetic material structure used to prevent water seepage. It is commonly used in the construction of constructed wetlands to ensure that water in the wetland does not seep into the foundation layer or the external environment.

[0003] During use, geomembranes may become loose due to strong winds or other weather conditions, which can reduce their impermeability and prevent water or liquid from seeping in. Therefore, we propose a geomembrane impermeability layer protection structure for artificial wetlands. Utility Model Content

[0004] The purpose of this invention is to provide a geomembrane anti-seepage layer protection structure for artificial wetlands, aiming to solve or at least partially solve the shortcomings of the aforementioned background technology. It can not only stabilize the position of the geomembrane and ensure that the geomembrane is tightly attached to the foundation layer to prevent water seepage, but also prevent the formation of air bubbles between the geomembrane and the foundation layer, ensuring that the geomembrane effectively isolates the seepage of groundwater or other liquids and improves the overall anti-seepage effect.

[0005] This utility model provides a geomembrane impermeable layer protection structure for constructed wetlands, including a fixing mechanism and a venting mechanism. Several fixing mechanisms are set on the foundation layer and are used to clamp and stabilize the geomembrane. The venting mechanism is set on the geomembrane and is used to discharge air bubbles in the geomembrane below. The fixing mechanism includes a fixed frame and a movable frame. The fixed frame is set on the foundation layer, and the movable frame is movably set on the fixed frame and can move vertically. A T-shaped block protrudes from the side of the movable frame facing the fixed frame. The fixed frame has an adjustment groove that cooperates with the T-shaped block. The T-shaped block can move vertically along the adjustment groove. A locking member is screwed onto the T-shaped block. The locking member can pass through the T-shaped block and abut against the fixed frame to lock the vertical position of the movable frame. The movable frame is also provided with a clamping unit for clamping the geomembrane. The clamping unit can move vertically with the movable frame. In use, the lower surface of the movable frame abuts against the foundation layer.

[0006] Furthermore, the clamping unit includes an adjusting rod, a clamping plate screwed to the adjusting rod, and a base plate fixed to the bottom wall of the movable frame. The two ends of the adjusting rod are rotatably connected to the top wall and the base plate of the movable frame, respectively. The clamping plate can move vertically along the adjusting rod to clamp the geomembrane between the clamping plate and the base plate.

[0007] Furthermore, a toothed plate is fixed to the lower surface of the movable frame; when in use, the teeth of the toothed plate are inserted into the base layer.

[0008] Furthermore, a limiting block protrudes from the side of the movable frame facing the fixed frame, and the fixed frame has a limiting groove that cooperates with the limiting block.

[0009] Furthermore, a handle is fixed to the upper surface of the movable frame.

[0010] Furthermore, the lower end of the fixing frame extends horizontally with at least one extension plate, which is fixedly connected to the base layer by at least one fastener.

[0011] Furthermore, the locking element is a bolt.

[0012] Furthermore, the venting mechanism includes an venting cylinder disposed on the upper surface of the geomembrane and a limiting member elastically disposed on the venting cylinder. The venting cylinder penetrates the geomembrane and has a venting hole through its side wall. The venting hole can be connected to the foundation layer below the geomembrane. The limiting member is used to connect or cut off the passage between the venting hole and the foundation layer below the geomembrane.

[0013] Furthermore, the limiting component includes an abutment block located on the upper surface of the exhaust pipe, a limiting block disposed inside the exhaust pipe, and a connecting rod connecting the abutment block and the limiting block. The connecting rod passes through the upper surface of the exhaust pipe, and an elastic element is sleeved on the connecting rod. The two ends of the elastic element abut against the inner top wall of the exhaust pipe and the upper surface of the limiting block, respectively.

[0014] Furthermore, the side wall of the limiting block is provided with a guide block protruding, and the exhaust pipe is provided with a guide groove that matches the guide block.

[0015] This utility model provides a geomembrane impermeable layer protection structure for constructed wetlands. Through the cooperation of a fixed frame, a movable frame, and a clamping unit, the geomembrane can be clamped in the clamping unit. At the same time, the vertical position of the movable frame can be adjusted to ensure that the geomembrane is tightly attached to the foundation layer, reducing gaps or wrinkles between the geomembrane and the foundation layer and preventing water seepage. By setting an air venting mechanism on the geomembrane, air bubbles can be prevented from forming between the geomembrane and the foundation layer, thereby preventing air bubbles from damaging the integrity of the impermeable layer and ensuring that the geomembrane effectively isolates the infiltration of groundwater or other liquids, thus improving the overall impermeability.

It should be understood that the use of directional terms should not limit the scope of protection claimed in this application.

[0028] Please see Figures 1-4This utility model is a geomembrane seepage prevention layer protection structure for artificial wetlands, including a fixing mechanism 20 and an air venting mechanism 30. Several fixing mechanisms 20 are set on the foundation layer and are used to clamp and stabilize the geomembrane 10. The air venting mechanism 30 is set on the geomembrane 10 and is used to discharge air bubbles under the geomembrane 10.

[0029] The fixing mechanism 20 includes a fixed frame 21 and a movable frame 22. The fixed frame 21 is set on the foundation layer, and the movable frame 22 is movably set on the fixed frame 21 and can move vertically. A T-shaped block 221 protrudes from the side of the movable frame 22 facing the fixed frame 21. The fixed frame 21 has an adjustment groove 212 that cooperates with the T-shaped block 221. The T-shaped block 221 can move vertically along the adjustment groove 212. A locking member 222 is screwed onto the T-shaped block 221. The locking member 222 can pass through the T-shaped block 221 and abut against the fixed frame 21 to lock the vertical position of the movable frame 22. The movable frame 22 is also provided with a clamping unit 23 for clamping the geomembrane 10. The clamping unit 23 can move vertically with the movable frame 22.

[0030] When in use, the lower surface of the movable frame 22 abuts against the base layer.

[0031] More specifically, in this embodiment, the locking element 222 is a bolt.

[0032] As described above, the geomembrane impermeable layer protection structure for artificial wetlands provided by this utility model, through the cooperation of the fixed frame 21, the movable frame 22, and the clamping unit 23, can clamp the geomembrane 10 in the clamping unit 23. At the same time, the vertical position of the movable frame 22 can be adjusted to make the geomembrane 10 fit tightly with the foundation layer, reducing the gaps or wrinkles between the geomembrane 10 and the foundation layer, and preventing water seepage. By setting an air venting mechanism 30 on the geomembrane 10, air bubbles can be prevented from forming between the geomembrane 10 and the foundation layer, thereby preventing air bubbles from damaging the integrity of the impermeable layer, ensuring that the geomembrane 10 effectively isolates the seepage of groundwater or other liquids, thereby improving the overall impermeability.

[0033] Furthermore, the clamping unit 23 includes an adjusting rod 231, a clamping plate 232 screwed to the adjusting rod 231, and a base plate 233 fixed to the inner bottom wall of the movable frame 22. The two ends of the adjusting rod 231 are rotatably connected to the top wall of the movable frame 22 and the base plate 233, respectively. The clamping plate 232 can move vertically along the adjusting rod 231 to clamp the geomembrane 10 between the clamping plate 232 and the base plate 233. In use, rotating the adjusting rod 231 causes the clamping plate 232 to move downwards, and the clamping plate 232 and the base plate 233 clamp and fix the geomembrane 10.

[0034] Furthermore, a toothed plate 224 is fixed to the lower surface of the movable frame 22. When in use, the teeth of the toothed plate 224 are inserted into the foundation layer to stabilize the movable frame 22, thereby stabilizing the position of the geomembrane 10.

[0035] Furthermore, a limiting block 223 protrudes from the side of the movable frame 22 facing the fixed frame 21, and the fixed frame 21 has a limiting groove 213 that cooperates with the limiting block 223. When the movable frame 22 moves vertically on the fixed frame 21, the sliding of the limiting block 223 in the limiting groove 213 can improve the stability and smoothness of the vertical movement of the movable frame 22.

[0036] Furthermore, a handle 225 is fixed to the upper surface of the movable frame 22. Workers can move the movable frame 22 directly using the handle 225, increasing ease of use.

[0037] Furthermore, the lower end of the fixing frame 21 extends horizontally with at least one extension plate 211, and the extension plate 211 is fixedly connected to the base layer by at least one fastener 214. In this embodiment, the fixing frame 21 is symmetrically provided with two extension plates 211, and one extension plate 211 is fixedly connected to the base layer by two fasteners 214.

[0038] Please see Figure 5 and Figure 6 The venting mechanism 30 includes an venting cylinder 31 disposed on the upper surface of the geomembrane 10 and a limiting member 32 elastically disposed on the venting cylinder 31. The venting cylinder 31 penetrates the geomembrane 10, and a venting hole 311 is formed through the side wall of the venting cylinder 31. The venting hole 311 can communicate with the foundation layer below the geomembrane 10. The limiting member 32 is used to connect or disconnect the passage between the venting hole 311 and the foundation layer below the geomembrane 10. When there is a large amount of gas below the geomembrane 10, the gas will push the limiting member 32 upward. At this time, the lower surface of the limiting member 32 is higher than the lowest point of the venting hole 311, so that the venting hole 311 communicates with the foundation layer below the geomembrane 10, and the gas is discharged through the venting hole 311. When the gas is gradually discharged, the pressure of the gas is insufficient to push the limiting member 32 upward, so the limiting member 32 gradually returns to its original position, thereby disconnecting the passage between the venting hole 311 and the foundation layer below the geomembrane 10.

[0039] Furthermore, the limiting member 32 includes an abutment block 322 located on the upper surface of the exhaust pipe 31, a limiting block 321 disposed inside the exhaust pipe 31, and a connecting rod 323 connecting the abutment block 322 and the limiting block 321. The connecting rod 323 penetrates the upper surface of the exhaust pipe 31, and an elastic member 33 is sleeved on the connecting rod 323. The two ends of the elastic member 33 abut against the inner top wall of the exhaust pipe 31 and the upper surface of the limiting block 321, respectively. In this embodiment, the elastic member 33 is a spring.

[0040] Furthermore, the side wall of the limiting block 321 is provided with a guide block 3211, and the exhaust pipe 31 is provided with a guide groove 312 that cooperates with the guide block 3211. The cooperation between the guide block 3211 and the guide groove 312 can limit the movement trajectory of the limiting block 321 in the exhaust pipe 31, and make the movement process smoother.

[0041] The usage process of the fixing mechanism 20 for the geomembrane seepage prevention layer protection structure of the artificial wetland provided by this utility model is as follows:

[0042] (1) Place the fixing frame 21 at the four corners of the geomembrane 10 where it needs to be installed, and then nail the fastener 214 into the mud to complete the initial positioning.

[0043] (2) Place the geomembrane 10 between the base plate 233 and the clamping plate 232, rotate the adjusting rod 231 to make the clamping plate 232 move downward along the adjusting rod 231, and the clamping plate 232 and the base plate 233 clamp the geomembrane 10 to complete the clamping and fixing of the geomembrane 10.

[0044] (3) Push the handle 225 of the movable frame 22 downward so that the movable frame 22 moves downward until the teeth of the toothed plate 224 are inserted into the soil. Then lock the movable frame 22 by the locking piece 222 to stabilize the installation position of the geomembrane 10.

[0045] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
