Width: The thickness is 4m: 2mm~8mm 1. When the load is 720kPa, the gradient is 2%, the permeability is 2500m / d, and the flow rate is 13 pm/m. 2. In the bear 1200kPa load creep test after 10,000 hours,it retains more than 60% of the thickness. Three-dimensional three-dimensional drainage network drainage network 3, three ribs water network core carbon black content of not less than 2%, the density of 0.94g / cm3, tensile strength of not less than 36.5kN / m, a melt index of 1.0 g / 10min, a thickness of 7.6mm. 4. The apparent?aperture of the non-woven geotextile is about 0.18mm, the water permeability is 0.26 Sec-1, the permeability 0.2cm / sec, the puncture strength 580N, the trapezoidal tear strength of 356 N, holding the tensile strength of 900 N, extended grip strength 50% of the burst strength 2750kPa.
The plastic?drainage?plate, also known as the plastic drain with several shapes of wavy type, Harmonica type, and so on. The middle is an extruded plastic core, skeleton and channel drainage belt, which is parallel cross section was discharged on both sides in a non-woven geotextile fabric wrap for the filter layer, the core band play a supportive role and the filter layer of water seeping up , silt, silt soil quality, and other saturated hydraulic fill filling viscous and miscellaneous drainage consolidation method using soft foundation treatment good vertical channels, greatly reducing the soft soil consolidation time.
