Production line and technology of three-layer drainage network

The drainage network is made of high-density polyethylene, and the ribs are extruded through a special machine head. The three ribs are arranged at a certain distance and angle to form a spatial structure with drainage guide grooves. The drainage channel formed between the three-layer ribs is not easy to deform under high load, which can prevent the geotextile from embedding into the geonet core and ensure smooth drainage.
