3D Drainage Geocomposites Geonet With Nonwoven Geotextile

3D Drainage Geocomposites Geonet With Nonwoven Geotextile

HDPE Drainage geonet Description
Three-dimensional composite Geonet is a new type of drainage Geosynthetics Materials. With high density polyethylene (HDPE) as raw material, after special extrusion process forming special structure with three layers. The middle rod with a good rigidity, end-to-end setup, formating drainage channels; The top and bottom cross rod form support to prevent Nonwoven geotextile embedded drainage channel, even under high load can keep high drainage performance.

Double-sided adhesive geotextile compound using, with "filter - drainage - air - protection" comprehensive performance. It`s the most ideal material of drainage now. Geonets can replace the traditional sand and gravel layer, Mainly used in drainage of landfills, roadbed and tunnel lining.

Three-dimensional drainage network (also known as three-dimensional geotechnical drainage board, tunnel drainage board, drainage water board) is composed of three-dimensional plastic mesh with one side bonded to filter geotextile and one side bonded with anti-seepage geomembrane. It can replace the traditional sand and gravel layer. It is mainly used for drainage of landfills, roadbeds and inner walls of tunnels.

The characteristics of three-dimensional composite drainage geonets network:
1. When the load is 720kPa and the gradient is 2%, the permeability is 2500m/d and the flow rate is 13pm/m.
2. After the creep test bears a load of 1200kPa for 10,000 hours, more than 60% of the thickness is retained.
3. The carbon black content of the three-rib drainage mesh core is not less than 2%, the density is 0.94g/cm3, the tensile strength is not less than 36.5kN/m, the melt index is 1.0 g/10min, and the thickness is 7.6mm.
4. The apparent pore size of the non-woven geotextile is 0.18mm, the water permeability is 0.26 Sec-1, the permeability is 0.2cm/sec, the puncture strength is 580N, the trapezoidal tear strength is 356 N, the holding tensile strength is 900 N, the holding elongation strength is 50%, and the burst strength is 2750kPa.
