Shandong Tianhai 3 d compound drainage nets by special 3 d geotechnical nets double bond geotextile is made. A combination of geotextile (filtrate) and long nets (drainage and protection), provide complete "inverted filter-drainage--to protect" effect. Drainage nets core adopt new high density polyethylene raw materials, to add 2-3% of the carbon black and ultraviolet and antioxidant stabilizer, through the special extrusion processing from way. Materials in before they leave the factory, all the quality indexes have been strictly test. 3 d geotechnical nets from three layer crisscross the muscles of composition, and a layer of the reinforced rigid great article, a vertical distribution, formation drainage channels, 3 d soil drainage network has very high vertical drainage capacity. Up and down the crisscross rib can effectively prevent geotextile embedded drainage channels, make 3 d geotechnical compound drainage nets in very high load will still be able to keep the higher under the row of performance. 3 d composite soil drainage nets can be used for high performance requirements of drainage situations, such as rainfall more areas sealing field guide line of surface water system.
Application:
Landfill drainage; Highway roadbed and pavement drainage; Railway soft soil foundation reinforcement drainage; Railway roadbed drainage, railway and the way of ballastless ballastless row water, drainage tunnel; Underground structure drainage; Retaining wall wall back drainage; The garden and playgrounds of drainage.
Product features:
The drainage, and a strong ability to money under high pressure load for a long time Money extremely high tensile strength and shear strength To reduce net geotextiles othermeasuring embedded core chance, can protect the long-term stability of hydraulic conductivity Money 3 d composite drainage nets can withstand more than 2000 kpa compression load Money far outweigh the ordinary drainage nets compressive capacity
