Geonet for a geocomposite
View Patent ↗A geocomposite for use in a landfill, including a geonet and a geotextile bonded to at least one side of the geonet. The geonet includes a first plurality of substantially parallel strands, and a second plurality of substantially parallel strands disposed on top of the first plurality of strands, the second plurality of strands being at an angle relative to the first plurality of strands. The first and second plurality of strands are substantially incompressible and secured to one another at crossover locations, and are substantially round in cross-section.
1. A geonet for use in a geotechnical construction site, consisting of:
a first plurality of substantially parallel strands substantially uniformly spaced from one another;
a second plurality of substantially parallel strands substantially uniformly spaced from one another and disposed on top of said first plurality of strands, said second plurality of strands being at an angle relative to said first plurality of strands;
whereby said first and second plurality of strands are substantially incompressible and secured to one another by connected areas at crossover locations, and at least one of said first and second plurality of strands is substantially round in cross-section.
2. The geonet of claim 1 , wherein said strands are high density polyethylene (HDPE).
3. The geonet of claim 1 , wherein both of said first and second plurality of strands are substantially round in cross-section.
4. A geocomposite for use in a geotechnical construction site, comprising:
a geonet consisting of
a first plurality of substantially parallel strands, and
a second plurality of substantially parallel strands disposed on top of said first plurality of strands, said second plurality of strands being at an angle relative to said first plurality of strands,
whereby said first and second plurality of strands are substantially incompressible and secured to one another by connected areas at crossover locations, and at least one of said first and second plurality of strands is substantially round in cross-section; and
a geotextile bonded to at least one side of said of said geonet.
5. The geocomposite of claim 4 , wherein said strands are high density polyethylene (HDPE).
6. The geocomposite of claim 4 , wherein both of said first and second plurality of strands are substantially round in cross-section.
7. The geocomposite of claim 4 , wherein said geotextile is non-woven textile heat laminated to said geonet strands.
8. The geocomposite of claim 7 , wherein said strands are high density polyethylene (HDPE).
9. The geocomposite of claim 7 , wherein said geotextile is non-woven needlepunched textile heat laminated to strands on both sides of said geonet.
10. The geocomposite of claim 9 , wherein said strands are high density polyethylene (HDPE).
11. The geocomposite of claim 4 , wherein said geotextile is spun-bonded or heat laminated textile heat laminated to strands on both sides of said geonet.
12. The geocomposite of claim 11 , wherein said strands are high density polyethylene (HDPE).
13. A landfill comprising alternating layers of fill and geocomposites, said geocomposites each disposed beneath a layer of fill to facilitate draining of liquid from the landfill and comprising:
a geonet consisting of
a first plurality of substantially parallel strands, and
a second plurality of substantially parallel strands disposed on top of said first plurality of strands, said second plurality of strands being at an angle relative to said first plurality of strands,
whereby said first and second plurality of strands are secured to one another by connected areas at crossover locations, and at least one of said first and second plurality of strands is substantially round in cross-section; and
a geotextile bonded to both sides of said of said geonet.
14. The landfill of claim 13 , wherein said strands are high density polyethylene (HDPE).
15. The landfill of claim 13 , wherein both of said first and second plurality of strands are substantially round in cross-section.
16. The landfill of claim 13 , wherein said geotextile is non-woven needlepunched textile heat laminated to strands on both sides of said geonet.
17. The landfill of claim 16 , wherein said strands are high density polyethylene (HDPE).
18. A geonet for use in a geotechnical construction site, consisting of:
a first plurality of substantially parallel strands substantially uniformly spaced from one another;
a second plurality of substantially parallel strands substantially uniformly spaced from one another and disposed on top of said first plurality of strands, said second plurality of strands being at an angle relative to said first plurality of strands;
whereby said first and second plurality of strands are substantially incompressible and secured to one another by connected areas at crossover locations, and at least one of said first and second plurality of strands is substantially round in cross-section.
