[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following will, in conjunction with the accompanying Figures 1-4 drawings of the embodiments of the present utility model, clearly and completely describe the technical solutions of the embodiments of the present utility model. Obviously, the described embodiments are some, rather than all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present utility model fall within the scope of protection of the present utility model.

[0027] As Figures 1-4 shown in the figure: This embodiment provides an anti-warping structure for an anti-seepage membrane, which includes a first anti-seepage membrane 1 and a second anti-seepage membrane 2. An anti-warping component 3 is provided at the top of the first anti-seepage membrane 1 and the second anti-seepage membrane 2, and a fixing component 4 is provided inside the anti-warping component 3.

[0028] The anti-warping component 3 includes a fixing frame 301. A screw rod 304 is threadedly connected to the top side inside the fixing frame 301. The top end of the screw rod 304 extends to the outside of the fixing frame 301 and is fixedly connected to a first turning handle 305. The bottom end of the screw rod 304 is fixedly connected to a tapered needle 306, and the bottom of the tapered needle 306 extends to the bottom of the first anti-seepage membrane 1 and the second anti-seepage membrane 2, and is used to drive the screw rod 304 to rotate through the first turning handle 305, so that the tapered needle 306 moves downward to assist in pressing and anti-warping the overlapping joint of the first anti-seepage membrane 1 and the second anti-seepage membrane 2. One side of the fixing frame 301 is fixedly connected to a dovetail block 302. A dovetail groove is provided on the other side inside the fixing frame 301. The dovetail groove is slidably connected to the dovetail block 302, and a stop block 303 is provided on one side of the dovetail groove. One side inside the stop block 303 is fixedly connected to a pin shaft, and the pin shaft is rotatably connected to the top side inside the fixing frame 301.

[0029] Specific implementation manner: First, the first anti-seepage membrane 1 and the second anti-seepage membrane 2 are overlapped and laid on the oilfield ground. Then, the staff manually operates a plurality of fixing frames 301 to drive the dovetail blocks 302 to sequentially enter the dovetail grooves opened in another dovetail block 302. Finally, the staff manually operates the stop block 303 to rotate by 90 degrees so that it is located at the top of the dovetail block 302 to ensure the installation portability and stability between the plurality of fixing frames 301. At this time, the fixing frame 301 will be linearly pressed on the top of the overlapping part of the first anti-seepage membrane 1 and the second anti-seepage membrane 2. After that, the staff manually operates the first turning handle 305 to drive the screw rod 304 to rotate and screw into the inside of the fixing frame 301. By using the linkage effect between the screw rod 304 and the tapered needle 306, the power is transmitted to the tapered needle 306, causing the tapered needle 306 to move downward. At this time, the tapered needle 306 will pass through the first anti-seepage membrane 1 and the second anti-seepage membrane 2 and extend to their bottoms, and fix it to the oilfield ground at the bottom, so that the fixing frame 301 presses and fixes the overlapping part of the first anti-seepage membrane 1 and the second anti-seepage membrane 2 to prevent it from warping during use and prevent the anti-seepage effect at the connection of the first anti-seepage membrane 1 and the second anti-seepage membrane 2 from being affected, thereby ensuring the overall service performance of the structure.

[0030] The fixing assembly 4 includes a first cavity 401. The first cavity 401 is located at the bottom side inside the tapered needle 306. A lead screw 402 is arranged inside the first cavity 401. The top end of the lead screw 402 is fixedly connected to a rotating shaft 403. The top end of the rotating shaft 403 extends to the outside of the first turning handle 305 and is fixedly connected to a second turning handle 404. The rotating shaft 403 is rotatably connected inside the first turning handle 305 and the tapered needle 306. A threaded sleeve 405 is threadedly connected to the outside of the lead screw 402. The threaded sleeve 405 is tapered. A plurality of rollers 406 are arranged on both sides of the bottom of the threaded sleeve 405. A connecting shaft is fixedly connected inside the roller 406. The outer peripheral side of the connecting shaft is rotatably connected to a fixing frame 407. Two springs 408 are fixedly connected to the side of the fixing frame 407 away from the roller 406. The other side of the spring 408 is fixedly connected to the inner wall of the tapered needle 306. A side needle 409 is arranged between the two springs 408. One side of the side needle 409 is fixedly connected to the fixing frame 407, and the side needle 409 is slidably sealed inside the tapered needle 306. Circular through holes are opened on both sides inside the threaded sleeve 405. A limiting rod 410 is slidably connected inside the circular through hole. The top end of the limiting rod 410 is fixedly connected to the inner wall of the tapered needle 306.

[0031] **Specific implementation method**: The staff manually operates the second rotating handle 404 to drive the rotating shaft 403 and the lead screw 402 to rotate. By utilizing the linkage effect between the lead screw 402 and the threaded sleeve 405, the power is transmitted to the threaded sleeve 405, causing the threaded sleeve 405 to move downward and squeeze the roller 406, the fixed frame 407, and the spring 408. As a result, the roller 406 and the fixed frame 407 drive the side needle 409 to move outward from the conical needle 306, further improving the fixing effect of the fixed frame 301 and the conical needle 306 on the oilfield ground, effectively ensuring the fitting effect of the first anti-seepage membrane 1 and the second anti-seepage membrane 2 with the oilfield ground, and thus assisting in improving the pressing and anti-warping effect of the fixed frame 301 on the overlapping part of the first anti-seepage membrane 1 and the second anti-seepage membrane 2.

[0032] **Working principle**: First, the first anti-seepage membrane 1 and the second anti-seepage membrane 2 are overlapped and laid on the oilfield ground. Then, the staff manually operates multiple fixed frames 301 to drive the dovetail blocks 302 to sequentially enter the dovetail grooves opened in another dovetail block 302. Finally, the staff manually operates the stop block 303 to rotate 90 degrees so that it is located at the top of the dovetail block 302. At this time, the fixed frame 301 will press straight on the top of the overlapping part of the first anti-seepage membrane 1 and the second anti-seepage membrane 2. After that, the staff manually operates the first rotating handle 305 to drive the screw 304 to rotate and screw it into the interior of the fixed frame 301. By utilizing the linkage effect between the screw 304 and the conical needle 306, the power is transmitted to the conical needle 306, causing the conical needle 306 to move downward. At this time, the conical needle 306 will penetrate through the first anti-seepage membrane 1 and the second anti-seepage membrane 2 and extend to their bottoms, and fix it with the oilfield ground at the bottom, so as to press and fix the overlapping part of the first anti-seepage membrane 1 and the second anti-seepage membrane 2 by the fixed frame 301. After that, the staff manually operates the second rotating handle 404 to drive the rotating shaft 403 and the lead screw 402 to rotate. By utilizing the linkage effect between the lead screw 402 and the threaded sleeve 405, the power is transmitted to the threaded sleeve 405, causing the threaded sleeve 405 to move downward and squeeze the roller 406, the fixed frame 407, and the spring 408. As a result, the roller 406 and the fixed frame 407 drive the side needle 409 to move outward from the conical needle 306, further improving the pressing and anti-warping effect of the fixed frame 301 on the first anti-seepage membrane 1 and the second anti-seepage membrane 2.

[0033] In addition, it should be noted that in the description of the present utility model, unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense.

For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0034] The above are the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle described in the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
