The introduction and application of 3D drainage geonet:
1.The 3D drainage net also called 3D geotechnique drainage board, it is a new type of drainage geotextile materials.
2.The material of 3D drainage net is HDPE,and it has three layers of special structure.
3.Intermediate longitudinal bars, the longitudinal arrangement, rigid formation drainage channels, the muscles of the upper cross arrangement formed support prevent geotextile embedded drainage channels, even in high load, also can maintain high drainage performance.
4.Drainage nets double-sided adhesive water seepage geotextile compound use attached, it is the most ideal drainage material.
5.Property:inverted filter, drain away water, ventilation, protection.
The spec and property indexes of 3D drainage geonet:
Mass per unit (g/m2) | Thickness (mm) | Mesh size (mm) | Width deviation (m) | Length deviation (m) | Tensile yield strength (KN/m) | |
1 | 750±35 | ≥6.0 | 10+1*10+1 | +0.060 | +1.0 | ≥6.0 |
2 | 1240±60 | ≥5.0 | 10+1*6+1 | +0.060 | +1.0 | ≥18 |
