Geo Bout point 1, high strength, due to the use of plastic fibers in wet state can maintain sufficient strength and elongation. 2, corrosion resistance, at different pH of soil and water can be permanently resistant to corrosion. 3, permeable fortunately there are gaps between the fibers, so it is good water permeability. 4, anti-microbial resistance to micro-organisms, insects are not compromised. 5, the construction is convenient, since the light weight, soft, and therefore transportation, laying and easy construction. 6, complete specifications: width up to 9 m. It is currently the most wide product mass per unit area: 100-1000g / m geotextile action 1: isolate the use of polyester staple fiber needle geotextile for building materials have different physical properties (particle size distribution, consistency and density, etc.) (such as soil and sand, soil and other concrete) isolation. So between two or more materials is not lost, not mixed, maintaining the overall structure and function of materials, so that load bearing capacity of structures strengthened. 2: Filtration (filtration) When the water flows into the soil of coarse material from fine soil materials, the use of polyester staple fiber geotextile good air permeability and water permeability, water flow through, while effectively carrying soil particles, fine sand, small stones, so as to maintain a stable water and soil engineering. 3: Drainage polyester staple fiber geotextile has good water conductivity properties, it can formed inside the soil drainage channels within the structure of the soil efflux of excess liquids and gases. 4: use of reinforced polyester staple fiber needle geotextile reinforced soil tensile strength and resistance to deformation, enhance the stability of the building structure in order to improve soil quality. 5: protection of water when the soil to erosion, effective stress will focus on proliferation, transfer, or decomposition, to prevent soil damage by external force and which protect the soil. 6: puncture and combined into composite waterproof geomembrane impermeable material, play a role in anti-puncture. High tensile strength, good permeability, air permeability, high temperature, anti-freeze, anti-aging, corrosion, moth-eaten. Polyester staple fiber needle geotextile is a widely used geosynthetics. Reinforced widely used in railway embankment, road surface conservation, sports hall, dams protection, hydraulic construction of isolation, tunnel in a coastal beach, land reclamation and environmental protection projects. Geotextile applications (1) for reinforced retaining wall backfill, or for anchoring retaining wall panels. The wrap-built retaining wall or abutment. (2) reinforced flexible pavement, repair cracks on the road surface to prevent reflection crack. (3) Increase gravel reinforced soil slope stability and prevent frost damage when soil erosion and low temperatures. (4) road barrier layer between the ballast and subgrade, or barrier layer between the roadbed and the soft base. (5) artificial fill, isolation or rockfill material field and ground isolation layer between different permafrost. Filtration and reinforcement role. (6) The ash storage dam or tailings dam upstream dam surface of the initial filter layer, retaining wall backfill in the drainage system filter layer. (7) Drainage Ditch drainage underground pipe or gravel surrounding the periphery of the filter layer. (8) hydraulic engineering in wells, wells or vacuum filter layer baroclinic tube. (9) highways, airports, railways and other road twitter and artificial rockfill and geotextile ground between barrier. (10) Dam internal vertical or horizontal drainage, buried in the soil pore water pressure dissipated. (11) earth dam or embankment in the Geomembrane surface cover the lower part of the back or concrete drainage. (12) to exclude the surrounding tunnel seepage, reduce water seepage around the lining is exposed to the external water pressure and various buildings. (13) artificial fill and drainage Ground Stadium Foundation. (14) road (including temporary roads) railway, embankment, dam, airports, stadiums and other projects to strengthen the soft ground.
