Needle punched non-woven bag is a new type of material in slope engineering, which is made from polypropylene (PP) or polyester fiber (PET) as raw material, and is made of two sided pressing and needle punched non-woven fabric. Eco bag thickness, unit quality, physical and mechanical properties, shape, fiber type, force, direction, size, anti-aging and permeability and meet plant growth equivalent aperture were strictly screened, with anti UV, anti itch, non-toxic, non combustion, the characteristics of high strength, tear the breach does not extend the true zero pollution. Mainly used in the construction of flexible ecological slope.
application area
Ecological restoration
1 the two sides of the river: the natural environment of the coexistence of human and wildlife.
2 green mine: ore comprehensive utilization of gangue, scientific renovation subsidence area, green hills, clean water, a mine ecological restoration, a of green hills.
3 sea shore lake, surface landslide, culvert hole, drainage ditch, soil erosion, irrigation system.
4 constructed wetlands: ecological restoration
5, roof greening
Infrastructure construction
1 Road: railway, highway slope, slope protection for excavation slope and fill slope.
2 rivers and lakes protection: for rivers, lakes and reservoirs in the slope.
3 special applications: military facilities and emergency flood control levees, bunkers, etc..
Landscaping and residential
1 vertical greening, garden art;
2 commercial residential quarters;
3 Roof garden green.
3 specification parameter 45*85cm
Plane size range: (can be customized according to the design and engineering requirements)
Fabric weight range: a wide range, common with 150g, 200g, 300g, etc.
The fabric tensile strength: more than 4.5kN/m
Fabric elongation: 40%
Calculation formula of the volume of the ecological bag forming:
Length = length of the ecological bag - (12~15) cm,
Width = width *0.7
Height = the height of the ecological bag *0.4
For example: outside diameter specifications for the 810mm*430mm bag, the soil after the specification is about the length of 65cm, width 30cm, height 15cm (ecological bag specifications and soil forming specifications, can be designed according to the actual requirements. Allowable maximum deviation is 2%)
Technical index reference
At present our country for Eco bags is national and industry standards, according to the technical parameters of the people's Republic of geosynthetics filament spunbond needle punched geotextile national standard GB/T 17639-2008.
