3-D drainage network (also alternate name 3-D geotextile drainage board, drainage network, drainage waterproof board) is mainly used for subgrade, tunnel wall and drainage of new products. Is by the three-dimensional structure of the plastic net double-sided adhesive ooze water of geotextile.
New type 3-D drainage network with HDPE as raw material, through the special extrusion is made. Drainage network has three layer bar structure, including a layer of rigid big bar vertical arrangement, the other two layer bar cross array, forming longitudinal arrangement drainage channel. Drainage network has the very high tensile strength and compression performance, staggered the bar can prevent geotextile embedded led to drainage channel jam, reduce the drainage capacity. 3-D drainage network general double or single compound geotextile, form a composite geotextile drainage network. New type 3 d drainage network drainage ability same as 1 m thick gravel. Used for landfill drainage and road drainage.
