Polypropylene Needle Punched Nonwoven Geotextile
Polypropylene geotextile can be widely used in hydropower, highways, railways, ports, airports, sports venues, tunnels, coastal mudflats, reclamation, environmental protection and other fields to play an isolationGeotextiles are almost used in high-grade highway construction in foreign countries, and they are also being used in China.
Impermeable geotextile refers to a geotechnical impermeable material composed of plastic film as an impermeable substrate and non-woven fabric. It can effectively intercept sand erosion, discharge excess liquid and gas in the soil structure, and enhance the stability of the building structure to improve the quality of the soil.
The raw materials of the ecological bag do not absorb water, and the bag will not be damaged when moisture appears, and the bag will not be deformed and insoluble in polluting liquids (EPA Method 9090 United States Environment Agency).
Eco-bag is made of double-sided ironing needle-punched non-woven fabric made of polypropylene (PP) or polyester fiber (PET). The thickness, unit mass, physical and mechanical properties, shape, fiber type, force mode, direction, geometric size and water permeability of the anti-ultraviolet ecological bag have been strictly screened
Eco-bag has excellent physical and chemical properties, this specially formulated material can resist the erosion of ultraviolet rays, is not affected by chemicals in the soil, will not undergo qualitative change or decay
It can be used as a cushion to deal with weak foundations to increase the bearing capacity of the foundation, and can also be laid on the slope to form a slope protection structure, and can also be used to build a retaining structure.
It has free telescopic and retractable transportation, and can be stretched into a network during construction, filled with loose materials such as soil, gravel, concrete, etc., to form a structure with strong lateral restriction and large stiffness.
Geocells are mainly made of HDPE (high-density polyethylene) or PP (polypropylene) sheets, which are strongly welded or riveted to form a mesh cell structure. It is flexible and can be retracted and stacked when transported
The common cell height is 5 cm, 7.5 cm, 10 cm, 15 cm, 20 cm, 30 cm, etc., and the commonly used welding torch is 330mm, 400mm, 500mm, 600mm, 660mm, 712mm, 800mm, 900mm, 1000mm, etc.,
