The geotechnical fabric, also known as the earth fabric, is made of synthetic fibers that are made of permeable synthetic material through a needle or needle. The earthwork cloth is one of the new materials, the finished product is the cloth shape, the general width is 4-6 meters, the length is 50-100 meters. The earthwork cloth is divided into a nonwoven fabric and a nonwoven filament cloth.
The geotechnical fabric has the characteristics of excellent filtration, drainage, isolation, reinforcement and protection, with light weight, high tensile strength, good permeability, high temperature resistance, freezing resistance, aging resistance and corrosion resistance. The application of geosynthetic materials originated in 1950s, domestic geotextiles is one of the national 85 program, China promulgated the "geosynthetics fiber needle punched geotextile in 1998" (GB/T17638-1998) standard, the geotextile has been in many fields has been widely used.
