Release time:
2020-04-12
The role of geotextile is a permeable geosynthetic material made of synthetic fibers through needle punching or weaving. The finished product is cloth-like, generally 4-6 meters in width and 50-100 meters in length. Geotextiles are divided into woven geotextiles and non-woven geotextiles. Geotextile has excellent filtering, isolation, reinforcement and protection, high tensile strength, good permeability, high temperature resistance, freezing resistance, aging resistance, and corrosion resistance. Non-woven geotextile: Non-woven geotextile is made of filaments or short fibers that are laid out into a net through different equipment and processes. After needle punching and other processes, different fibers are intertwined with each other, entangled and fixed to standardize the fabric , Make the fabric soft, plump, thick and stiff to achieve different thicknesses to meet the requirements of use. Non-woven geotextiles have good fabric gaps and good adhesion and separation. Due to the soft fibers, they have a certain resistance to tearing. Good deformation adaptability and good flat drainage ability. The surface is soft and has a good coefficient of friction. It can increase the adhesion of soil particles and prevent the loss of fine particles while eliminating excess water. , The surface is soft and has good protection ability. According to the length of the filament, it is divided into filament non-woven geotextile or short filament non-woven geotextile. They can play a very good filtering, isolation, reinforcement, protection and other effects, is a widely used geosynthetic material. The tensile strength of filament is higher than that of short filament, so it can be selected according to specific requirements. Woven geotextile (reinforced geotextile): Woven geotextile is composed of at least two sets of parallel yarns (or flat yarns), one set is called warp along the longitudinal direction of the loom (the direction in which the fabric travels), and the other The horizontal arrangement is called the weft. The warp and weft are woven into a cloth shape with different weaving equipment and processes, which can be woven into different thicknesses and densities according to different ranges of use. Generally, spinning geotextiles have relatively thin vertical and horizontal directions. Tensile strength (longitude is greater than latitude), with good stability. Spun geotextiles are divided into two categories: reinforced geotextiles and unreinforced geotextiles according to the weaving process and the use of warp and weft. The warp tensile strength of reinforced geotextiles is much greater than that of ordinary geotextiles. The general practical application of woven geotextiles and the reinforcement of geotechnical engineering projects. The main function is reinforcement and reinforcement. It has the function of plane isolation and protection. It does not have the function of plane drainage and can be selected according to the specific purpose of use. The application characteristics of geotextiles: 1. Since the synthetic fibers currently used in the production of geotextiles are mainly nylon, polyester, polypropylene, and polyethylene, they all have strong anti-burial and corrosion resistance properties. 2. The geotextile is a permeable material, so it has a good filter and isolation function. 3. The non-woven geotextile has a fluffy structure and has good drainage performance. 4. The geotextile has good puncture resistance, so it has good protection Performance 5. Geotextile has a good coefficient of friction and tensile strength, and has geo-reinforced properties.
