[0033] In order to more clearly understand the above-mentioned objectives, features and advantages of the present invention, the scheme of the present invention will be further described below. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0034] The following description sets forth many specific details to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; obviously, the implementation methods in the specification are only part of the implementation methods of the present invention, rather than all of the implementation methods.

[0035] Combination Figure 1 and Figure 2 As shown, the novel anti-seepage membrane transverse plug-in device provided in the embodiment of the present invention comprises a plug-in unit 1 and a connector 2.

[0036] The plug-in 1 includes a plug-in body 11 and a first connecting section 12, wherein the first connecting section 12 is an extension of the plug-in body 11, and the first connecting section 12 is used to connect to the anti-seepage membrane 4 on one side. The connector 2 includes a connector body 21 and a second connecting section 22, wherein the second connecting section 22 is an extension of the connector body 21, and the second connecting section 22 is used to connect to the anti-seepage membrane 4 on the other side. The connector body 21 is provided with an inner cavity 211 and a socket 212 connected to the inner cavity 211, wherein the inner cavity 211 extends in a vertical direction, the socket 212 also extends in a vertical direction, and the socket 212 is connected to the inner cavity 211, and the inner cavity 211 has enough space to facilitate the insertion of the plug-in body 11, and the plug-in body 11 can be inserted into the inner cavity 211 through the socket 212 to realize the connection between the plug-in body 11 and the connector body 21, thereby realizing the connection between two adjacent anti-seepage membranes 4. A seal 3 is provided between the plug-in body 11 and the inner cavity 211 to achieve a sealed connection between the plug-in body 11 and the connector body 21 to prevent water leakage. The inner cavity 211 can limit the movement of the plug-in body 11 toward the socket 212, thereby preventing the plug-in body 11 from separating from the connector body 21 and ensuring the connection effect.

[0037] When in use, the novel anti-seepage membrane transverse plug-in device provided by the present invention is connected to the anti-seepage membrane 4 on one side through the first connecting section 12, and is connected to the anti-seepage membrane 4 on the other side through the second connecting section 22, and then the plug-in body 11 is inserted into the inner cavity 211. It is easy to operate and increases construction efficiency. The inner cavity 211 can prevent the plug-in body 11 from falling out, ensuring the connection effect. A sealing member 3 is provided between the plug-in body 11 and the inner cavity 211 to increase the sealing effect of the plug-in device.

[0038] In some embodiments, Figure 2 As shown, the cross-sectional dimension of the plug-in body 11 gradually decreases along the direction toward the insertion end of the plug-in body 11 , so as to form first slope surfaces 112 on both sides of the plug-in body 11 .

[0039] Under this design, the size of the insertion end of the plug-in body 11 is relatively small, which facilitates the insertion end of the plug-in body 11 to pass through the socket 212. During the insertion process of the plug-in body 11, the first slope surface 112 can guide the insertion of the plug-in body 11, so as to facilitate the insertion of the plug-in body 11 into the inner cavity 211, thereby increasing the convenience of connecting the plug-in body 11 with the connector body 21.

[0040] In some embodiments, the cross-sectional dimension of the plug-in body 11 gradually decreases along the direction toward the insertion end of the plug-in body 11 , so that the cross-sectional dimension of the plug-in body 11 is tapered.

[0041] In this design, the tapered design makes it easier for the insertion end of the plug-in body 11 to pass through the socket 212 and extend into the inner cavity 211, which can further increase the convenience of connection.

[0042] In some embodiments, a portion of the plug-in body 11 that is away from the insertion end of the plug-in body 11 extends outward to form two clamping blocks 111 , and the inner cavity 211 is formed with a clamping groove 2111 that matches the clamping block 111 .

[0043] In this design, when the plug-in body 11 is inserted into the inner cavity 211 , the block 111 can be inserted into the slot 2111 to limit the block 111 and the plug-in body 11 through the slot 2111 to prevent the plug-in body 11 from moving toward the socket 212 .

[0044] In some embodiments, Figure 2 As shown, the cross-sectional dimension of the block 111 gradually decreases along the direction away from the plug-in body 11, so that the second slope surface 113 is formed on both sides of the block 111, wherein the slope of the second slope surface 113 connected to the first slope surface 112 is consistent with the slope of the first slope surface 112, so that the first slope surface 112 and the second slope surface 113 form a plane, which is convenient for the plug-in body 11 to be inserted into the inner cavity 211. The ends of the second slope surface 113 on the side corresponding to the two blocks 111 can be connected or not connected, and are designed according to actual needs. Accordingly, the slot 2111 is a groove structure, and the two slots 2111 are located on both sides of the socket 212. A third slope surface is formed at the position corresponding to the slot 2111 and the block 111, and the slope of the third slope surface is consistent with the slope of the second slope surface 113, ensuring the positioning effect between the block 111 and the slot 2111.

[0045] In some embodiments, the plug-in body 11 and the two blocks 111 form an arrow-shaped structure. In this design, the cross-sectional dimension of the plug-in body 11 gradually decreases in the direction toward the insertion end of the plug-in body 11, and the cross-sectional dimension of the plug-in body 11 is tapered. At the same time, the portion of the plug-in body 11 that is away from the insertion end of the plug-in body 11 extends outward to form two blocks 111, and the cross-sectional dimension of the two blocks 111 gradually decreases in the direction away from the plug-in body 11, so that the cross-sectional dimension of the blocks 111 is also tapered. At the same time, the slope of the second slope surface 113 of the block 111 connected to the first slope surface 112 is consistent with the slope of the first slope surface 112, so that the plug-in body 11 and the two blocks 111 form an arrow-shaped structure, ensuring the convenience of inserting the plug-in body 11 into the inner cavity 211, and at the same time, preventing the plug-in body 11 from escaping from the inner cavity 211.

[0046] In some embodiments, the first connecting section 12 is located between the two clamping blocks 111 , so that the plug-in body 11 located on both sides of the first connecting section 12 is symmetrically arranged, thereby increasing the convenience of operation.

[0047] In some embodiments, the second connecting section 22 is disposed on the other side of the joint body 21 where the socket 212 is disposed, and the first connecting section 12 and the second connecting section 22 are disposed in parallel, so that the two connected anti-seepage membranes 4 are disposed in parallel.

[0048] In some embodiments, the shape of the inner cavity 211 matches the shape of the arrow-shaped structure. The matching here means that the shape of the inner cavity 211 is the same as or similar to the shape of the arrow-shaped structure. Under this design, the opening area of ​​the inner cavity 211 can be made smaller, avoiding affecting the structural strength of the joint body 21.

[0049] In some embodiments, Figure 2 As shown, the cross-sectional shape of the connector body 21 matches the cross-sectional shape of the arrow-shaped structure. In this design, the connector body 21 is more compatible with the plug body 11, and the outer area of ​​the connector body 21 can be reduced, so that the plug 1 has better operability during the lateral insertion process.

[0050] In some embodiments, a guide surface 2121 is formed on a side of the socket 212 facing away from the inner cavity 211 to facilitate the insertion of the plug-in body 11 .

[0051] In some embodiments, Figure 1 As shown, the cross-section of the joint body 21 is rectangular. This design makes the structure of the joint body 21 more regular and convenient for operation and construction.

[0052] In some embodiments, the seal 3 is disposed between the block 111 and the slot 2111. Specifically, a seal 3 is disposed between the second slope surface 113 on one side of the two blocks 111 and the third slope surface of the slot 2111 to prevent fluid from entering the gap between the block 111 and the slot 2111 through the socket 212.

[0053] In some embodiments, the outer side of the arrow-shaped structure is formed into a smooth surface. This design reduces the friction between the plug of the arrow-shaped structure and the socket 212 , making it easier for the plug of the arrow-shaped structure to pass through the socket 212 and be inserted into the inner cavity 211 .

[0054] In some embodiments, a rough surface is formed on the inner side of the block 111. This design can increase the friction between the block 111 and the inner wall of the slot 2111, increase the limiting effect of the block 111, and prevent the plug-in body 11 from escaping from the inner cavity 211.

[0055] In some embodiments, the connector body 21 is made of elastic material at least at the position where the socket 212 is provided. In this design, when the plug-in body 11 passes through the socket 212, the position of the socket 212 of the connector body 21 can be deformed to avoid the plug-in body 11 passing through, ensuring that the plug-in body 11 can pass through the socket 212.

[0056] In some embodiments, the plug-in body 11 has a certain strength, has a small deformation during the extrusion process, and prevents the plug-in body 11 from being separated from the inner cavity 211 after being inserted into the inner cavity 211 .

[0057] In some embodiments, the structure of the slot 2111 matches the structure of the block 111, and the two slots 2111 are located on both sides of the socket 212 to form a block structure with a gradually decreasing cross-sectional size on both sides of the socket 212. The block structure is conducive to deformation toward the slot 2111, but is not convenient for deformation in a direction away from the slot 2111, thereby preventing the plug-in body 11 from detaching from the inner cavity 211.

[0058] In some embodiments, the seal 3 includes an expansion strip 31 disposed between the plug-in body 11 and the inner wall of the inner cavity 211. The expansion strip 31 can expand when exposed to water, and seal the gap between the plug-in body 11 and the inner wall of the inner cavity 211 to ensure a sealing effect. The expansion strip 31 is fixed to the block 111 by bonding or other methods, which can be selected according to actual needs.

[0059] In some embodiments, the expansion strip 31 is disposed on the second slope surface 113 on the side corresponding to the two clamping blocks 111. During the insertion process, the plug-in body 11 will not scratch the expansion strip 31, ensuring the use of the expansion strip 31. In addition, after the plug-in body 11 is inserted into the inner cavity 211, the expansion strip 31 is brought into contact with the third slope surface of the clamping groove 2111 by pulling back the plug-in body 11, so that the expansion strip 31 is located between the clamping block 111 and the inner wall of the clamping groove 2111.

[0060] In some embodiments, the plug-in body 11 and the first connecting section 12 are integrally formed to ensure the structural strength and manufacturing convenience of the plug-in 1 .

[0061] In some embodiments, the connector body 21 and the second connecting section 22 are integrally formed to ensure the structural strength and manufacturing convenience of the connector 2 .

[0062] In some embodiments, the anti-seepage membrane 4 is made of high-performance PE material, which has strong welding adhesion and is easy to connect with the first connecting section 12 or the second connecting section 22.

[0063] The present invention also provides a construction method for the above-mentioned new type of anti-seepage membrane transverse plug-in device, comprising the following steps: connecting with the anti-seepage membrane 4 on one side through the first connecting section 12, connecting with the anti-seepage membrane 4 on the other side through the second connecting section 22, and then inserting the plug-in body 11 into the inner cavity 211 of the joint 2.

[0064] It can be seen that the construction method of the novel anti-seepage membrane transverse plug-in device is simple to operate and can increase construction efficiency.

[0065] In some embodiments, the operation mode of the novel anti-seepage membrane transverse plug-in device provided by the present invention is as follows:

[0066] Step S1, prepare a plurality of plug-ins 1 and connectors 2.

[0067] Step S2 , attaching expansion strips 31 to the inner sides of the two clamping blocks 111 of each plug-in 1 .

[0068] Step S3, connecting the first connecting section 12 and the second connecting section 22 to the anti-seepage membrane 4 respectively.

[0069] Step S4 , inserting the arrow-shaped structure into the inner cavity 211 through the insertion port 212 .

[0070] Step S5 , pull the plug-in 1 outwards so that the expansion strip 31 is tightly fixed between the card block 111 and the inner wall of the card slot 2111 .

[0071] Step S6, repeating steps S3 to S5 until a plurality of anti-seepage membranes 4 are connected together through a plurality of plug-ins 1 and connectors 2.

[0072] The new anti-seepage membrane transverse plug-in device under this design mode is easy to operate and increases work efficiency.
