250g Geotextile Fabric Function:
1.Inverted Filtration
Inverted flitration refers to that tp prevent soil particles from running off under the osmotic pressure while allow liquid to penetrate.Polyester spunbonded needle punched geotextile is available to replace the traditional grit inverted layer and possesss the advantages of reducing engineering work load,convenient for construction and speedy.
a.inverted filtration of abamurus and drain
fliament spunbond geotextile is availbale for the inverted layer of roadbed revetment,counterfort,abamurus back side and covered drain.
b.inverted filatration of dam and revetment
fliament spunbond geotextile is available for the inverted lays at the backsides of water-retaining structures such as surfaces at the upper and lower branches of core wall or miter wall of earth-rock dam,earth-rock cofferdam and revetment,etc
2.water-draining
water-draining refers to enable water to drain out of earth mass or geotechnical structures through the permeable channel by use of material penetrability.filament spunbond needle punched geotextile is available to replace the traditional water-draining structure such as gravels and concrete pipe and is convenient for construction with bargain price and reliable quality.
a.roadbed & road surface water-draining
complex engineering measures of filament spunbond needle punched geotextile in roadbed and road surface constructions of highroads and railways are available to drain off surface water and lower the groundwater table,so as to maintain the stability of roadbeds.
3.segregation
segregation refers to that to prevent adjacent mediums of different natrure from mixing.the degregation of filament spunbond needle punched geotextile is available for being laid onto the auger ground before enrockment for the improvement of foundation intensity.
a.segregation & anti-seepage of waster landfill site
The composite spunbond needle punched geotextile is available for segregation ans anti-seepage of waste landfill site to prevent noxious liquid from permeating soil and noxious gas from diffusing,so as to reduce environmental pollution and increase land use ratio.
4.reinforcement
reinforcement refers to add materials of certian tensile strength into earth mass for performance improvement.it will achieve better effects for improving the intensity and stability of earth mass and convenient for construction.
a.earth slope reinforcement
The geotextile in slope reinforcement of highrodas and railways will improce the slope stability,enlarge the slope and reduce the lans use.
b.roadbed reinforcement
it use as reinforcement material in roadbed earthfilling will increase the sustainability and stability of roadbed .
5.anti-seepage
anti-seepage refers to that to prevent liquid from draining off in infiltration.the geotextile as anti-seepage layer will be economical,durable and pollition-free.
a.dam anti-seepage
it is available as anti-seepage layer for dam miter wall or core wall,dam horizontal anti-seepage overspread and vertical anti-seepage wall on the percious foundation,as well as concrete and rolled concrete dams.
b.channel anti-seepage
the geotextile is available for acequia and headrace as anti-seepage layer with convenienve for construction.
