Drainage board sub roll and sheet two series in which the web is divided into "hot melt" and "lap" and "self" into three types, using a special process modeling plastic sheet extrusion closed convex cylindrical shell body, forming a lenticular film, continuous shell, with three-dimensional space and some support height, hot glue butyl rubber Beihai geotechnical drainage board manufacturers when edge processing, top of the shell covering the North Sea geotextile filter layer soil drainage board manufacturers, for seepage, hydrophobic, drainage and water storage products. Also known as: self-adhesive PE drainage board, row sparse board, drainage protection board, drainage board, plastic bump drainage board, plastic sandwich panels. Major categories commonly used in the construction of drainage board are: self-adhesive PE drainage board, plastic drainage board, build drainage board, coil drainage board, impervious to water drainage board, composite drainage board, three-dimensional drainage board, sheet drainage board. Landfill leachate drainage layer and leak detection layer cushioned system to prevent leakage and ensure the safety of the landfill, leachate drainage system must have a reliable drainage performance exhaust system to collect leachate liner to ensure that the head is less than the saturated pad leachate drainage layer thickness. Traditional sand and gravel and other natural drainage material for landfill leachate collection discharge guide, will take up a lot of landfill space. For leachate drainage slope, using sand and gravel will be difficult to stack. Using geotextile composite drainage network, essentially independent of the slope gradient limit. As gravel leachate collection discharge guide layer, impermeable geomembrane will cause damage. According to statistics, the gravel geomembrane laying geomembrane is the biggest cause of the destruction of more than 70% of the total damage. Three-dimensional geotextile composite drainage network has three-dimensional stereoscopic discharge guide structure, the use of high permeability of geotextile composite, at very high load can maintain long-term performance discharge guide for primary leachate collection discharge guide layer (LCRS) North geotextile drainage board manufacturers, the timely discharge of leachate impermeable membrane so that the head is less than the thickness of the material soil drainage, reduce the head caused by excessive seepage geomembrane.
