Production line and technology of 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 layers of reinforcing bars is not easy to deform under high load, which can prevent the geotextile from embedding into the geonet core and ensure smooth drainage.
