[0002] Geomembrane is a geotechnical anti-seepage material made of plastic film as the anti-seepage base material and non-woven fabric. Its anti-seepage performance mainly depends on the anti-seepage performance of the plastic film. They are a kind of polymer chemical flexible material with the advantages of small specific gravity, strong elongation, high adaptability to deformation, corrosion resistance, low temperature resistance and good anti-freezing performance. Its main mechanism is to use the impermeability of plastic film to cut off the leakage channel of earth dam, and to withstand water pressure and adapt to the deformation of dam body with its large tensile strength and elongation. Non-woven fabric is also a kind of polymer short fiber chemical material, which is formed by needle punching or hot bonding, and has high tensile strength and elongation.

[0003] When geomembranes are used over a large area, they need to be welded. When actually welding geomembranes, there is usually a lot of debris on the surface of the geomembrane, which affects the normal operation of the geomembrane welding machine. To ensure the normal welding work, the surface of the geomembrane needs to be cleaned by manpower alone.
