The American Society of agricultural engineers refers to geotextiles as the data of geotextiles or geotechnical components between soil and pipes, gabions or retaining walls. These data can enhance the movement of water and hinder the movement of soil. Geotextile, also known as geotextile, is a kind of permeable fabric made of geotechnical materials. It is used for soil, rock, soil or other geotechnical engineering materials, and as a part of artificial engineering to achieve structural effects. Geotextile materials should not only consider the physical and chemical properties required by the application environment, but also pay attention to the product cost.
Geotextile is an outstanding hydraulic conductivity material
When the water in the soil layer washes the coarse material in the soil layer, the needle punched geotextile with excellent permeability and permeability is used to make the water flow through and effectively prevent the flow of soil particles, yarn, small stones, etc., so as to ensure the stability of water and soil engineering. Drainage effect of geotextile geotextile is a kind of excellent water conducting material. It can form a drainage channel in the soil and discharge the residual liquid structure gas out of the body. Reinforcement effect of geotextile needle shaped geotextile is used to enhance the tensile strength and resistance to soil changes, increase the stability of building structure, and improve soil quality.
The construction method of filament geotextile is as follows:
1. the filament geotextile shall be laid by manual rolling method, and the cloth surface shall be flat with appropriate deformation allowance;
2. the hand-held sewing machine shall be used for sewing the filament geotextile, and the hour interval shall be controlled at about 6mm. The stitching strength of the upper geotextile and the foundation geotextile shall not be less than 70% of the strength of the geotextile itself.
3. select the splicing method of filament geotextile, and the splicing width shall not be less than 0.1 M;
4. all stitches shall be carried out continuously, and no point stitch is allowed. The minimum needle distance is 2.50cm;
5. the thread used for sewing shall be a resin material with a minimum tension of more than 60N, and have appropriate or ultra-high chemical corrosion resistance and ultraviolet radiation resistance of the geotextile;
6. in case of needle skipping and other unqualified phenomena, repair from scratch at the suture
