[0004] However, in the implementation of relevant technologies, it was found that the above technical solution has the following problems: during use, the above device lacks the function of high-strength tightening the connection between the PE pipe and the PE geomembrane, which makes the connection between the PE pipe and the PE geomembrane prone to leakage under long-term use, resulting in sealing problems in the PE pipeline, affecting its normal use effect. Therefore, further improvement is needed. Utility Model Content

[0008] Preferably, a clamp is provided on the outer surface of the first polyethylene geomembrane body for clamping the membrane sleeve and the polyethylene pipe body to prevent the welding point between the membrane sleeve and the polyethylene pipe body from cracking or desoldering due to external force.

[0009] Preferably, a second polyethylene geomembrane body is provided on the outer surface of the clamp to protect the first polyethylene geomembrane body and the pipe clamp from erosion by external media, thereby achieving the safety and sealing of the connection structure where the polyethylene pipe body passes through the PE geomembrane, and ensuring that there is no leakage at the connection between the polyethylene pipe body and the PE geomembrane.

[0010] Preferably, a fixing component for bolting and fixing the clamp to the outer surface of the first polyethylene geomembrane body is provided on the outer side of the clamp.

[0015] The working principle and beneficial effects of the utility model are as follows:

[0016] The utility model fully utilizes the characteristics that the polyethylene pipe body and the first polyethylene geomembrane body and the second polyethylene geomembrane body are made of the same material and can be welded, and uses the membrane sleeve as a connecting transition structure to ensure the safety and sealing of the structure at the connection between the polyethylene pipe body and the first polyethylene geomembrane body and the second polyethylene geomembrane body, and prevents liquid from penetrating the polyethylene pipe body through the connection between the first polyethylene geomembrane body and the second polyethylene geomembrane body.
