Staple acupuncture geotextile definition refers to a synthetic material by needling process equipment from the processing of products, a cloth-like, finished width is generally 4,6,8 meters, volume is generally 50 meters long, 100 meters, or According to the project design requirements, staple acupuncture geotextile nickname is the earth's clothes, color is usually white. Staple acupuncture non-woven geotextile and an Industrial Fabrics. Functions and applications: a filtration function staple acupuncture geotextile has good water permeability, but also appropriately small gap, which is necessary to meet the requirements of the flow through, but also to prevent excessive loss of fundamental particles caused by piping and flow soil destruction, the use of geotextile this function in the actual project can be used instead of traditional anti-anxiety gravel layer, such as: 提坎 slope protection filter layer, filter layer after Hom drainage. 2. drainage geotextile has good vertical and horizontal drainage have appropriate small gap, so it is necessary to an effective drainage of the soil as the water pooled exclude, for example: Pull walls drainage, vertical ridge in vivo and horizontal drainage. 3. isolation isolation geotextile is to be separated in two different materials, to prevent cross mix, keeping the material state structure and function, so that the load bearing capacity of structures strengthened. 4. geotextile reinforced feature buried in the soil borrow geotextile and soil friction between soil lateral displacement limit, so that a loss of soil strength, increased carrying capacity, reinforced stress diffusion helps make adjustments such as soft soil base or insufficient strength of weir structures under various land
