The eco bag is a new type of material, which is made of polypropylene (PP) or polyester fiber (PET) as raw material, and the bag is made of two sides pressing and non woven fabrics. Against the ecological bag UV unit thickness, quality, physical and mechanical properties, shape, fiber type, force, direction, size and permeability and meet plant growth equivalent aperture were strictly screened, with anti ultraviolet (UV), anti ageing, non-toxic, non combustion, characteristics. No extension of 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 parameters
Design specifications and parameters
Plane size range: (can be customized according to the design and engineering requirements)
Fabric weight range: a wide range, common with 100g, 125g, 150g, 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.
