Also known as geotextile, it is a geosynthetic material made of polyester fibers by needle punching or weaving into cloth. The width is generally 4-6 meters, and the length is 50-100 meters. Geotextile is divided into woven geotextile and non-woven filament nonwoven geotextile factory price. Geotextile has the functions of filtering, drainage, isolation, reinforcement, anti-seepage and protection. Filament geotextile is one of non-woven and industrial non-woven fabrics, mainly used as geomaterials in civil engineering.
Isolation, that is, the use of geotextiles to isolate construction materials (such as soil and sand, sand and gravel, soil and concrete) with different physical properties (particle size, distribution, consistency and density). Two or more materials will not be lost or mixed, and maintain the overall structure and function of the material to enhance the load-bearing capacity of the structure. filter. When water flows from the fine-grained soil layer to the coarse-grained soil layer, the water flow passes through the good permeability and water permeability of the needle-punched filament nonwoven geotextile for sale. And effectively intercept soil particles, fine sand, small stones, etc., to maintain the stability of soil and water engineering. Drainage, filament geotextile is a good water-conducting material, it can form a drainage channel in the soil structure to exclude excess liquid and gas in the soil structure. It has the characteristics of isolation, good filtering performance, good corrosion resistance, reliable drainage performance and good protection performance.
Before installation and deployment, damage to the filament polypropylene nonwoven geotextile factory price should be avoided. Geotextiles should be stacked where there is no accumulated water. The height of the pile should not exceed four rolls. Geotextiles should be covered with opaque materials to prevent UV aging at the construction site. During storage, the integrity of labels and materials must be guaranteed. The main construction methods are as follows:
The laying of filament geotextile adopts manual rolling method, the surface of the fabric should be flat, and the deformation allowance should be properly retained; the polyester nonwoven geotextile factory price stitching is stitched by manual stitching machine. When stitching, the stitch length is controlled at about 6 mm. The stitching method of the upper geotextile and the lower geotextile should not be less than 70% of the strength of the geotextile itself. The stitching of geotextile stitching, the stitching width is not less than 0.10m; all stitching must be continuous, no point stitching is allowed, the smaller stitch is 2.50 cm from the edge; the thread used for sewing should be a resin material with a tension less than 60N Chemical resistance and UV resistance are equivalent to or exceed geotextiles; if the suture has phenomena such as skipping rope, the suture needs to be re-stitched at the suture and ensure that the end of the skipped part is re-stitched.
