Three dimensional composite drainage network
The three-dimensional geo composite drainage network is made of high-density polyethylene (HDPE). The ribs are extruded through a special die. The three ribs are arranged according to a certain distance and angle to form a three-dimensional spatial structure with drainage guide channel. The middle rib has greater rigidity, forming a rectangular drainage channel. The results show that the three-layer ribs of the drainage network have high longitudinal and transverse tensile strength and compressive strength; the drainage guide channel formed between the three-layer ribs is not easy to deform under high load, which can prevent the geotextile from embedding into the core of the geonet and ensure smooth drainage. The three-dimensional geotechnical drainage network has high strength and high drainage type according to the use.
