Road cloth, that is, geotextile, also known as geotextile, it is made of synthetic fibers through the needle or woven from the permeability of geosynthetics. Geotextile is a new material geosynthetics which one, the finished product for the cloth, the general width of 4-6 meters, the length of 50-100 meters. Geotextile is divided into a woven geotextile and non-woven geotextile. Geotextile with excellent filtration, drainage, isolation, reinforcement, protection, with a light weight, high tensile strength, good permeability, high temperature, anti-freeze, anti-aging, corrosion resistance characteristics. The application of geosynthetics originated in the 1950s, the domestic geotextile is one of the national eight five plan, China promulgated in 1998, "geosynthetics staple acupuncture non-woven geotextile" (GB / T -1998) standard, the current geotextile has been widely used in many areas. Geotextile mainly in the following three series: 1, acupuncture non-woven geotextile, specifications 100g / m2-600g / m2 between any choice, the main raw material is the use of polyester staple fiber or polypropylene staple fiber, made by acupuncture, Uses 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. 2, acupuncture non-woven 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 non-woven, PE film through the composite , The main purpose is anti-seepage, apply to railways, highways, tunnels, subways, airports and other projects. 3, non-woven and woven composite geotextile, a variety of non-woven and polypropylene filament woven composite, non-woven and plastic woven composite, suitable for foundation reinforcement, adjust the permeability coefficient of the basic engineering facilities.
The geotextile is defined as geotextiles or geosynthetics that exist between soils and pipelines, gages, or retaining walls, that enhance water movement and impede soil movement. ASTM 4439 standard geotextile is defined as: a purely permeable geosynthetics to form textiles. It is used in soil, rock, soil, or other geotechnical engineering materials and acts as a component of a human-made project. It is a permeable geosynthetics made of synthetic fibers by needling or weaving. Finished cloth for the cloth, the general width of 4-6 meters, the length of 50-100 meters. Geotextile is divided into a woven geotextile and non-woven geotextile. Geotextile has excellent filtration, isolation, reinforcement protection, high tensile strength, good permeability, high temperature, anti-freeze, anti-aging, corrosion resistance.
