PE Three-dimensional Drainage Network Production Line
The three-dimensional drainage network (also known as three-dimensional geotechnical drainage plate, tunnel drainage plate, and drainage plate) is composed of a three-dimensional plastic network with one side bonded to an inverted filter geotextile, and one side bonded to an impermeable geomembrane. It can replace traditional sand and gravel layers, and is mainly used for the drainage of landfills, roadbases, and inner walls of tunnels.
