Business consultingDetailed introduction
150/2-1600/2 three-dimensional composite drainage network
The three-dimensional composite drainage net is made of a unique three-dimensional geotextile bonded on both sides. The combination of geotextile (anti-filtration) and geotextile net (drainage and protection) provides a complete "anti-filtration --- ---- protection" effect.
The unique three-dimensional structure of the three-dimensional composite drainage network core can withstand high compression loads during the entire use process, and can maintain a considerable thickness, providing good hydraulic conductivity.
Typical applications: landfill drainage; highway subgrade and pavement drainage; railway drainage; tunnel drainage; underground structure drainage, retaining wall back drainage; garden and playground drainage.
Characteristics of three-dimensional composite drainage network
●Strong drainage capacity, can withstand long-term high pressure load
● Extremely high pit tensile strength and shear strength
● reduce the probability of geotextile embedded mesh core, can protect the long-term stability of hydraulic conductivity
● Three-dimensional composite drainage network can withstand more than 2000kpa compression load
● Far greater than the compressive capacity of ordinary drainage network
