Background

In the fields of domestic garbage landfill sites, hazardous waste landfill sites, general industrial solid waste landfill sites and the like, the situation that a PE pipe (polyethylene pipe) can penetrate through an impermeable film basically exists, so that the sealing performance of the impermeable film at the position is weakened, and the main reason of leakage at the position is proved by many leakage examples of the landfill sites that the impermeable film is torn at the position where the pipe penetrates through the film or the PE pipe and the impermeable film are welded. The damage of the tube through the membrane is caused by the following reasons:

1. the PE tube does not angle properly through the impermeable membrane. The acute angle formed between the PE pipe and the surface of the anti-seepage film ensures that the welding working surface is not enough, so that the phenomenon of insufficient welding occurs in the welding between the PE pipe and the anti-seepage film, and the PE pipe is detached to cause the seepage under the action of external force.

2. The pipe sleeve and the PE pipeline are suspended in the air, and the anti-seepage film is torn or the welding seam is torn to leak under the action of external force.
