Geotextile types and role of geotextiles which types, respectively, what role, filament geotextile, short geotextile, composite geotextile, respectively, what role? More
1, acupuncture non-woven geotextile, specifications 100g / m2-1000g / m2 between any choice, the main raw material is the use of polyester staple fiber or polypropylene staple fiber, made by acupuncture, the main purposes are: river, sea, lake Embankment slope protection, reclamation, wharf, ship lock flood control and other projects, is through the filter to play a soil and water conservation and effective way to prevent piping. Second, acupuncture non-woven fabrics and PE film composite geotextile, specifications have a cloth a film, two cloth a film, the largest width of 4.2 meters The main raw material is to use polyester staple fiber acupuncture non-woven, PE film through the composite , The main purpose is anti-seepage, apply to railways, highways, tunnels, subways, airports and other projects. Third, non-woven and woven composite geotextile, a variety of non-woven and polypropylene filament woven composite, non-woven and plastic woven composite, for the basis of reinforcement, adjust the permeability coefficient of the basic engineering facilities. Features: light weight, low cost, corrosion resistance, with a filter, drainage, isolation, enhance the excellent performance. Use: widely used in water conservancy, electricity, mines, roads and railways and other geotechnical projects: l, soil separation of the filter material; 2, reservoirs, mine mineral processing of drainage materials, high-rise building drainage materials; Of the anti-erosion material; geotextile features 1, high strength, due to the use of plastic fibers, in dry and wet state can maintain sufficient strength and elongation. 2, corrosion-resistant, in different pH of the soil and water can be long-term corrosion resistance. 3, good water permeability between the fiber gap, it has a good water permeability. 4, good microbial resistance to micro-organisms, insects are not damaged. 5, construction convenience
