Description

Technical Field

[0001] The utility model belongs to the technical field of solid waste disposal and pollution prevention and control, and specifically relates to a device for flexibly unfolding an anti-seepage membrane in a vertical anti-seepage wall with a simple structure, capable of avoiding tearing of the anti-seepage membrane and flexible adjustment. Background Art

[0002] A cutoff wall is a continuous wall constructed within loose, permeable layers or earth-rock dams (weirs) to prevent seepage. Due to its reliable structure, effective anti-seepage performance, adaptability to various ground conditions, ease of construction, and low cost, it has been widely used both domestically and internationally, particularly for addressing potential seepage and deformation hazards such as mine backfill, dam foundation leakage, soil flow, and piping behind dams.

[0003] An impermeable membrane is a synthetic geotechnical material used to prevent the penetration of water and other liquids. This membrane is primarily installed on the exterior of a building or underground project, leveraging its barrier properties to prevent vertical water penetration into the interior or outside a designated area. Currently, vertical impermeable water-stopping technology is being applied across a variety of fields due to engineering needs. Impermeable membranes are gaining increasing favor in the engineering community due to their significant economic and environmental benefits.

[0004] Flexible vertical waterproofing is often used for pollution prevention and control at solid waste disposal sites. The current technical solution is to cut grooves around the site and then vertically insert the waterproof membrane to the designed pollution prevention and control depth. Each piece of waterproof membrane is then connected in the vertical direction through a special lock. However, if the overlap area and overlap joints are large, the risk of leakage will increase.

[0005] In the prior art, patent document CN219098248U discloses an anti-seepage geomembrane deployment device. Although the deployment device in its technical solution can be used to deploy the anti-seepage membrane, since the anti-seepage membrane material is usually relatively thin and light, and has weak puncture resistance, it is easy for the anti-seepage membrane to be torn and cracked due to the large deployment force or contact with foreign objects during deployment, thereby affecting the final anti-seepage performance of the anti-seepage layer. In other words, the prior art has the following technical problems: when an ordinary deployment device is used to deploy the anti-seepage membrane, it is difficult to effectively control the deployment force, and it is easy for the anti-seepage membrane to be torn and cracked due to excessive force acting on the membrane during deployment. Therefore, how to control the force acting on the membrane during deployment to avoid the membrane from being torn and cracked is one of the problems that need to be solved urgently in the current flexible vertical anti-seepage technology.

[0046] The working principle and working process of this utility model:

[0047] like Figures 1 to 4 As shown, before laying the anti-seepage membrane 6, the present invention is first moved to the side of the vertical anti-seepage wall. The servo motor 12 is then activated, driving the threaded rod 14 to rotate and drive the two movable sliders 15 along the linear track beam 1, thereby adjusting the distance between the two fixing clamps 5 to the appropriate distance. The end of the anti-seepage membrane 6 is then clamped between the clamping plate 52 on one side and the bolts (i.e., adjustment units 53) on the clamping plate 52 are tightened to clamp the end of the anti-seepage membrane 6. The anti-seepage membrane 6 roll is then installed together with the core shaft on the clamping plate 52 on the other side to form a rotatable connection, finally forming a "scroll-like" unfolding connection of the anti-seepage membrane 6. Alternatively, the anti-seepage membrane 6 can be cut to a suitable length, and the ends of the cut anti-seepage membrane 6 are then clamped to the two fixing clamps 5 below the linear track beam 1. At the same time, according to the different materials and strengths of the anti-seepage membrane 6, the knob 46 can be manually adjusted to drive the threaded column 45 to rotate, and the threaded column 45 drives the rotating table 47 to move to squeeze the spring 48. The compressed spring 48 pushes the limit slider 49 to drive the push rod 4A to press against the T-shaped slide rail 42, so that by controlling the contraction amplitude of the spring 48, the pressure of the push rod 4A against the T-shaped slide rail 42 can be controlled, so that the damping value (i.e., friction resistance) of the sliding seat 43 moving along the T-shaped slide rail 42 is controlled by the pressure size to be no greater than the tearing threshold of the anti-seepage membrane 6.

[0048] During laying, the two ends of the anti-seepage membrane 6 are fixed to two fixing clamps 5 respectively, and then the cylinder (i.e., the linear drive unit 33) is activated to extend and retract, driving the anti-tear mechanism 4 to move vertically through the fixing seat 41, thereby moving the clamped anti-seepage membrane 6 into the pre-laid trench of the anti-seepage wall for laying. Subsequently, the servo motor 12 is activated to drive one or two fixing clamps 5 to move along the anti-seepage wall in the trench, so that the anti-seepage membrane 6 is unfolded and laid flat on the anti-seepage wall in a "scroll-like" manner to reduce overlap. During the laying process, when the fixing clamps 5 are driven by the servo motor 12 to unfold and lay the anti-seepage membrane 6, if the force (i.e., the pulling force) applied to the unfolding of the anti-seepage membrane 6 is greater than the damping value of the sliding seat 43 sliding along the T-shaped slide rail 42, the pulling force of the anti-seepage membrane 6 will cause the sliding seat 43 to slide on the T-shaped slide rail 42, thereby preventing the pulling force from continuing to increase on the anti-seepage membrane 6 through sliding, thereby preventing the anti-seepage membrane 6 from being torn or cracked due to excessive unfolding force.

[0049] 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.
