Specializing in the production of polyester filament geotextile price concessions quality assurance

Polyester filament geotextile purposes: 1. WATER filtration dams and slope, channel isolation, impervious; basic isolation 2 highways, railways, airport runways, filtration, drainage, slope, retaining walls and pavement reinforcement, drainage; soft foundation treatment 3. port engineering, beach causeway, harbor piers and breakwater reinforcement, drainage; 4. polyester filament geotextile is widely used in infrastructure construction, and gradually be applied to more a wide range of fields. Laying process polyester filament geotextile: 1, storage, transport and disposal of geotextile geotextile roll before installing Expand to avoid damage. Geotextile volume should not water stacked in place by the formation of high stack height does not exceed four volumes, and can see the identification sheet volume. Geotextile roll must be covered with an opaque material to prevent UV aging. During storage, to maintain the integrity and complete labeling information. During transport (including on-site storage of materials from land transport to the workplace), geotextiles volume must avoid damage. Physical damage of the geotextile volumes must be repaired. Severely worn geotextile not be used. Any contact with the leaking chemicals geotextile, are not allowed on this project. 2, the laying of geotextile method: 2.1 laying artificial roll; cloth for a smooth and appropriate deformed left margin. 2.2 filament or staple fiber geotextile installation usually overlap, stitching and welding in several ways. Stapling and welding width is generally 0.1m or more, typically 0.2M lap width or more. Possible long-term exposure of geotextile should be welded or stitched. 2.3 geotextile sewn stitching all must be continuous (for example, point sewing is not allowed). Prior to overlap the geotextile must overlap a minimum of 150mm. The minimum distance between the needle selvage (material exposed edges) is at least 25mm. Geotextile sewn seams and most include a row line-shaped locking chain stitch. Line for suturing should be minimum tension over 60N resin material, and a resistance to chemical corrosion and UV resistance and geotextile comparable or exceeded. On any sewn geotextiles "dropped stitch" must be re-stitched in the affected areas. We must take appropriate measures to avoid the installation, soil, particulate matter or foreign substances into the geotextile layer. Lap cloth according to the terrain and the use of natural features can be divided into lap, stitched or welded polyester filament geotextile polyester filament geotextile is also called non-woven geotextile filament / polyester non-woven geotextile / long silk spinning sticky geotextile / filament permeable geotextile / according to use can also be called permeable geotextile / polyethylene composite waterproof and can also be called with - waterproof geotextile waterproof geotextile Technical indicators generally calculated intensity distribution of the film !
