The geotextile is a new building materials, raw materials are synthetic fiber polyester, polypropylene, acrylic, nylon and other polymer. According to the manufacturing methods are divided into: there are two types of nonwoven geotextiles and geotextile. General engineering is the use of nonwoven geotextile. Geotextile has multiple functions of anti-seepage, anti filtration, drainage, isolation, reinforcement, protection, sealing, compared with the masonry and concrete anti-seepage effect with normal, has the advantages of low investment, simple construction process, short construction period , good anti-seepage effect, channel advantages of effective utilization coefficient. 2 characteristics 1, high strength, due to the use of plastic fiber, can maintain adequate strength and elongation under dry and wet conditions. 2, corrosion resistance, can be a long time corrosion in soil and water in different pH. 3, good water permeability, there are gaps in the fiber, it has good performance of water seepage. 4, anti microbial and good for microorganisms, moth eaten are not damaged. 5, the construction is convenient, the material is light, soft, so transporting, laying, convenient construction. 6, the specification is complete: up to 9 meters width. Is currently the most wide products, mass per unit area: 100-1000g/ square meters The 3 role 1: isolation To have different physical properties using polyester staple fiber needle punched geotextile (particle size, distribution, thickness and density of building materials) Material (such as soil and sand soil and concrete, etc.) isolation. The loss of two or more materials, not mixed, keep material The structure and function of the whole material, strengthen the building load bearing capacity. 2: filter (filter) When the water flows into the coarse material by fine soil layer, the use of polyester staple fiber needle punched geotextile has good air permeability and water permeability, make water flow Through, and effectively carrying current soil particles, sand, small stones and so on, in order to maintain the stability of soil and water engineering. 3: Drainage The water guide with good properties of polyester staple fiber needle punched geotextile soil, it can be formed within the drainage channel, the soil structure in The residual liquid and gas efflux. 4: reinforcement The tensile strength of the reinforced soil and anti deformation capacity utilization of polyester staple fiber needle punched geotextile, enhanced the stability of structures, in order to improve the Good soil quality. 5: Protection Water on soil erosion, effective will be concentrated stress diffusion, transfer or decomposition, prevent soil by external force damage, the protection of soil. 6: the puncture Combined with the geomembrane as impervious material composite waterproof, anti puncture plays the role of. High tensile strength, good permeability, air permeability, high temperature resistant, anti freeze, aging resistance, corrosion resistance, no moth. Polyester staple fiber needle punched geotextile geotechnical synthetic material is a kind of widely used. Reinforcement of highway pavement, widely used in Railway Subgrade Maintenance, sports hall, dyke protection, hydraulic construction of isolation, tunnel, coastal beach, reclamation, environmental protection engineering. 4 applications (1) as the retaining wall backfill reinforcement, or for anchored retaining wall panel. The construction of package type retaining wall or abutment. ?? The application of Geotextile in construction (2) reinforced flexible pavements, crack repair on the road, to prevent reflection crack of bituminous pavement. (3) to increase the stability of crushed stone slope and reinforced soil, prevent freezing soil erosion and the low temperature. (4) the isolation layer between the road ballast and subgrade, isolation layer or between the embankment and soft foundation. (5) the artificial filled soil and rockfill materials or field isolation layer and foundation, isolation between different frozen soil. The filter and the reinforcement effect. (6) the ash storage dam or tailings dam upstream dam surface at the early stage of the filter layer, filtering layer retaining wall back fill in drainage system. (7) or gravel filter layer surrounding the underground drain pipe drainage of the surrounding. (8) in water conservancy project wells, relief wells or inclined pipe filter layer. (9) the isolation layer soil between highway, airport, railway ballast and artificial rockfill and soil fabric. (10) in ternal vertical or horizontal drainage, the dissipation of pore water pressure in soil buried. (11) the drainage of Geomembrane in earth dam or embankment behind or concrete cover the lower part of the. (12) the exclusion of tunnel surrounding water seepage, reduce the lining is exposed to external water pressure and the seepage around buildings. (13) the artificial filling foundation motion field foundation drainage. (14) highway (including temporary road) railway, bank, embankment dams, airports, sports grounds and other engineering for strengthening soft foundation. 5 specifications and parameters Project \ \ number index specification 150200100250300350 400450500600800 note 1 mass per unit area deviation,% 88887777 666 The thickness of 2, mm = 0.9 1.3 1.7 2.1 2.4 2.7 3 3.3 3.6 4.1 5 3 amplitude deviation,% -0.5 4 breaking strength, KN/m = 2.5 4.5 6.5 8 9.5 11 12.5 14 16 19 25 vertical 5 elongation,% 25 ~ 100 6 CBR bursting strength, KN = 0.3 0.6 0.9 1.2 1.5 1.8 2.1 2.4 2.7 3.2 4 7 equivalent aperture of 0 (0), mm 0.07 ~ 0.2 8 vertical permeability coefficient, cm/s Kx (10 ~ 10) K=1.0 ~ 9.9 9 the tearing strength, KN = 0.08 0.12 0.16 0.20 0.24 0.28 0.33 0.38 0.42 0.46 0.60 vertical 1) specifications by the mass per unit area.
