[0042] Embodiment

[0043] As Figures 1-6 shown, the soil membrane joint fastening device provided by the present application is used to solve the technical problem that the soil membrane joint needs to be welded in the prior art, and the welding operation needs to clean the soil membrane, and the welding operation also needs a suitable environment, which will affect the construction efficiency.

[0044] The technical scheme of the present application includes the following specific structures:

[0045] Slot strip 1, wherein a slot 11 is provided on one side;

[0046] A connector 2 is provided on one side of the connector 2, and the connector 21 is inserted into the slot 11;

[0047] The top and bottom surfaces of the connector 21 are each provided with at least one elastic hook 211, and the slot 11 is provided with an elastic groove 111 that is adapted to the elastic hook 211.

[0048] like Figure 4 As shown, this utility model only requires wrapping the edges of adjacent geomembranes 4 onto the slot strip 1 and the plug strip 2 respectively, and then inserting and tightening the slot strip 1 and the plug strip 2 to complete the sealing connection of the geomembrane 4 joints. Welding is no longer required, and the geomembrane 4 joint connection operation can be completed quickly and efficiently.

[0049] When the geomembrane 4 needs to be removed, simply cut the geomembrane 4 at the adjacent position of the slot strip 1 and the plug strip 2, and then pull the plug strip 2 out from the end of the slot strip 1, so that it can be reused.

[0050] In one embodiment, the top surface of the slot strip 1 is arc-shaped, and when the slot strip 1 and the plug strip 2 are combined, the edge of the slot strip 1 extends out of the plug strip 2 towards one side of the plug strip 2.

[0051] The arc-shaped top surface of the slot strip 1 has two functions. One function is to reduce the resistance to the wheels of the tool cart and not to hinder the movement of the tool cart. The other function is to prevent water and debris from accumulating on the top surface. In particular, since the edge of the slot strip 1 extends beyond the range of the connector strip 2, water will not enter through the gap between the two.

[0052] Based on the above technical solution, the slot strip 1 and the plug strip 2 are made of rubber, plastic or metal.

[0053] When the slot strip 1 and the plug strip 2 are made of plastic or metal, the inner surface of the slot 11 is provided with a rubber layer, and the outer surface of the plug 21 is provided with a rubber layer.

[0054] In this embodiment, the materials of the slot strip 1 and the plug strip 2 can be divided into two main categories. One is to use rubber material, which has a certain degree of elasticity. When the size of the slot strip 1 and the plug strip 2 is appropriate (interference fit), both have a certain degree of elasticity, which can ensure the sealing degree of both. The other is to use plastic or metal material. These materials are rigid and have poor deformation ability. The advantage is that they will not deform, but the disadvantage is that they are difficult to seal (extremely high precision and surface roughness are required to complete the seal). Therefore, a rubber layer needs to be laid on the surface of the rigid material, and the elasticity of the rubber is used to achieve the seal.

[0055] In one embodiment, such as Figure 1 , Figure 2 and Figure 3 As shown, both the outer bottom edges of the slot strip 1 and the plug strip 2 are provided with limiting strips 3, and the limiting strips 3 are fixedly connected or magnetically connected to the slot strip 1 and the plug strip 2.

[0056] When the limiting strip 3 is fixedly connected to the slot strip 1 and the plug strip 2, a limiting groove 31 is formed on the limiting strip 3.

[0057] In this embodiment, the limiting strip 3 has two fixing methods. One is that the limiting strip 3 and the slot strip 1 or the plug strip 2 are manufactured as a whole, and then the limiting groove 31 is opened on the limiting strip 3. In this structure, when using it, the geomembrane 4 needs to be passed from the bottom of the limiting groove 31 to the top of the limiting groove 31, and then wrapped around the surface of the slot strip 1 or the plug strip 2. The other is that the limiting strip 3 and the slot strip 1 or the plug strip 2 are movably connected. For example, a magnetic block is embedded in the limiting strip 3, and a magnetic block is also embedded in the corresponding position on the surface of the slot strip 1 or the plug strip 2. The limiting strip 3 and the slot strip 1 or the plug strip 2 are connected by the magnetic block. When using it, the geomembrane 4 can be clamped by the limiting strip 3 and the slot strip 1 or the plug strip 2.

[0058] Regardless of the structure described above, the aim is to hold the geomembrane 4 in place by the limiting strip 3, allowing the geomembrane 4 to adhere to the surface of the ground, the slot strip 1, and the interlocking strip 2, preventing it from being suspended in the air and thus punctured.

[0059] In one embodiment, the cross-section of the elastic hook 211 is a right-angled triangle or an obtuse-angled triangle.

[0060] The right-angled triangle has the contact surface of the elastic hook 211 and the elastic slot 111 as the vertical surface, while the obtuse-angled triangle has the contact surface of the elastic hook 211 and the elastic slot 111 tilted towards the side of the plug strip 2, forming a barb shape; both structures ensure the fastening effect of the plug strip 2 and the slot strip 1.

[0061] like Figure 5 In one embodiment, fastening grooves are provided on the surface of the slot 11 and the surface of the connector 21, and fastening strips 12 are provided in the fastening grooves.

[0062] When the joint of the geomembrane 4 is overlapped and welded, the adjacent edges of the two geomembranes 4 need to be connected. Since the geomembrane 4 is relatively large, it is difficult for a single person to stably wrap different geomembranes 4 onto the slot strip or plug strip 2 at the same time. Therefore, it is necessary to use fastening strip 12 to fix the edge of the geomembrane 4 onto the plug strip 2 or slot strip 1. The fastening groove is set at the surface where the slot strip 1 and the plug strip 2 will fit together when they are combined, which can further improve the friction and compression force of fastening the geomembrane 4.

[0063] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
