Geotextile international brands Hebei Huayi Engineering Materials Co., Ltd. Feicheng geotextile is a new building materials, raw material is polyester, polypropylene, acrylic, nylon and other synthetic polymers. According to the manufacturing methods are divided into: woven geotextiles and non-woven geotextile types. General engineering mainly use non-woven geotextile. Geotextile with seepage, filtration, drainage, separation, reinforcement, protection, sealing and other functions, it is compared with conventional masonry and concrete material impervious effect, with Low investment and construction process is simple, short construction period, the effect of anti-seepage, effective channel utilization factor advantages. American Society of Agricultural Engineers will geotextile is defined as: exists between soil and pipe, gabion, or retaining walls, strengthen the soil water movement and impede the movement of the geotextile or geosynthetic materials. ASTM 4439 standard definition geotextile is: a purely permeable geosynthetic material textiles. Be used in soil, rock, earth or other materials related to geotechnical engineering and structural role to play as part of the project consisting of a human-made. Geotextile materials used not only to consider the use of the environment required for the physical and chemical properties, but also pay attention to product cost. Geotextile? Features 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 the soil and water can be permanently resistant to corrosion. 3, there is a gap between the fibers and good permeability, it has good water permeability. 4, anti-microbial resistance is good for microbes, insects are not compromised. 5, the construction convenient, because of light weight, soft, so transporting, laying, to facilitate construction. 6, complete specifications: width up to 9 m. Is currently the widest product, mass per unit area: 100-1000g / m. Geotextile role? 1: isolation of polyester staple fiber geotextile use of materials with different physical properties (particle size, distribution, consistency and density, etc.) (eg, soil and sand, soil and concrete, etc.) isolation. Make between two or more materials is not lost, not mixed, maintaining the overall structure and function of the material, so that load bearing capacity strengthening structures. 2: filter (filtration) when water flows into the soil coarse material from fine soil material, the use of polyester staple fiber geotextile good air permeability and water permeability, water flow through, and effective carrier soil particles, fine sand, small stones, etc., in order to maintain a stable soil and water engineering. 3: Polyester staple fiber geotextile drainage has good water conductivity properties, it can be formed inside the soil drainage channels within the structure of the soil efflux of excess liquids and gases. 4: The use of reinforced polyester staple fiber geotextile reinforced soil tensile strength and resistance to deformation, enhance the stability of the building structure in order to improve soil quality. 5: Protection against water when soil erosion, effective stress will focus on proliferation, transfer, or decomposition, to prevent soil and damage by external force, which protect the soil. 6: anti-puncture and water seepage geomembrane combined into a composite material, played the role of anti-puncture. High tensile strength, good permeability, air permeability, high temperature, anti-freeze, anti-aging, corrosion, moth-eaten. Polyester staple fiber geotextile is a widely used geosynthetics. Reinforced widely used in railway embankment, road surface conservation, sports hall, protective dams, hydraulic construction of isolation, tunnel in a coastal beach, land reclamation and environmental protection projects. What is failure? Nothing, just more successful move closer; what is success? Is gone all the way leading to failure, only the next road, it is a successful way. Geotextile? Applications (1) for the reinforced retaining wall backfill, or for anchoring retaining wall panels. Construction of retaining wall or abutment parcel. (2) reinforced flexible pavement, repairing cracks in the road, the road to prevent reflective cracking. (3) increase the gravel and reinforced soil slope stability, and prevent frost damage when soil erosion and low temperatures. (4) road barrier layer between the ballast and subgrade, or isolating layer between the embankment and soft ground. (5) manual filling, isolation or rockfill material field and ground isolation layer between different permafrost. Filtration and reinforcement effect. (6) ash storage dam or tailings dam upstream dam face initial filter layer, retaining wall backfill drainage system filter layer. (7) Drainage Ditch drainage underground pipe or gravel around the perimeter of the filter layer. (8) Water Project wells, vacuum filter layer baroclinic wells or tube. (9) highway, airport, railway track and artificial rockfill such as twitter and geotextile ground isolation between the layers. (10) Dam internal vertical or horizontal drainage, buried in the soil pore water pressure dissipation. (11) dam or embankment behind the Geomembrane or concrete surface cover the lower part of the drainage. (12) exclude neighboring tunnel seepage, reduce seepage lining around the various buildings to withstand the external water pressure. (13) artificial sports ground drainage fill foundation. (14) roads (including temporary road) railway embankment, dam, airports, stadiums and other projects in order to strengthen the weak foundation. What is failure? Nothing, just more successful move closer; what is success? Is gone all the way leading to failure, only the next road, it is a successful way. Feicheng Huayi geotextile quality is extremely heavy responsibility for the quality, heavy as Mount Tai. Ensure quality, accountability must be established quality layers responsible. This is Feicheng Huayi project quality assurance organization.
