Shandong Tianhai three-dimensional composite drainage network is made of a unique three-dimensional geonet bonded with geotextile on both sides. It combines geotextile (filtering function) and geonet (drainage and protection function), providing a complete “filtering - drainage - protection” effect. The drainage core is made of new high-density polyethylene material, adding 2-3% carbon black and UV and oxidation stabilizers, processed through a special extrusion method. Before leaving the factory, all quality control indicators are strictly tested. The three-dimensional geonet consists of three layers of interleaved ribs, with the middle layer having high rigidity and a vertical distribution, forming drainage channels. The three-dimensional geocomposite drainage network has a very high vertical drainage capacity. The interleaved ribs above and below can effectively prevent the geotextile from embedding into the drainage channels, ensuring that the three-dimensional geocomposite drainage network can maintain high drainage performance under heavy loads. The three-dimensional geocomposite drainage network can be used in situations requiring high drainage performance, such as surface water drainage systems for landfills in areas with high rainfall.
Application Range:
Landfill drainage; drainage for highway subgrades and pavements; drainage reinforcement for railway soft soil foundations; drainage for railway subgrades, track ballast, and tunnel drainage; underground structure drainage; drainage behind retaining walls; drainage for gardens and sports fields.
Product Features:
◎ Strong drainage capacity, able to withstand long-term high pressure loads;
◎ Extremely high tensile strength and shear strength;
◎ Reduces the chance of geotextile embedding into the core, protecting long-term stable water conductivity;
◎ The three-dimensional composite drainage network can withstand compression loads greater than 2000kPa;
◎ Much greater compressive strength than ordinary drainage networks;
