　　Anti seepage geotextile (composite geomembrane) refers to a geotextile anti-seepage material composed of plastic film as the anti-seepage substrate and non-woven fabric. Its anti-seepage performance mainly depends on the anti-seepage performance of the plastic film. At present, plastic films for anti-seepage applications in various regions and abroad mainly include polyvinyl chloride (PVC) and polyethylene (PE), which are high molecular weight chemical flexible materials with low specific gravity, strong extensibility, high adaptability to deformation, corrosion resistance, low temperature resistance, and good frost resistance.

　　Crawler welding machine can produce a seamless body with stable adhesion. Crawler welding machine plastic welding is limited to thermoplastic polymers because thermoplastic materials can be softened by heating, while thermosetting polymers cannot be softened by heating after hardening. Crawling welding machine for thermoplastic friction welding, in which one substrate is fixed and the other substrate rotates at a controlled angular velocity. When the components are pressed together, frictional heat causes the polymer to melt, and after cooling, welding is formed. The main welding parameters include: rotation speed, friction pressure, forging pressure, welding time, and melting length. Welding can produce excellent welding quality. The climbing welding machine is capable of welding almost all thermoplastic materials and has a great driving force for tunnel engineering.
