Precautions for Polyester Filament Geotextiles
Geotextile storage to meet the following requirements: the Treasury clean no debris, no chemical corrosion; not sun, tarnished; not weight, not scratch, to prevent violent collision; away from the hot source; dry and cool warehouse; There is a need for fire tools, fire hydrants, fire extinguishers and so on. Geotextile transport, loading and unloading requirements: can not be mixed with sharp items; hoisting with flexible rope; can not use steel wire rope directly hoisting; not with sticks, iron bars and other hardware auxiliary top loading; Stress dispersion measures, to avoid tightly tightened with a rope.
1. Geotextiles can only be cut with a geotextile (hook knife), such as in the field of cutting, other materials to take special protective measures to prevent the cutting of geotextiles and its unnecessary damage; Laying geotextile at the same time, must take all necessary measures to prevent damage to the following layer of material; 3. In the laying of geotextiles, we must pay attention not to let the stone, a lot of dust or moisture may damage the geotextile, Drains or filters, or materials that may cause difficulties for subsequent connections to enter beneath geotextiles or geotextiles; 4. After installation, visualize all geotextile surfaces to identify all damaged landlords Marking and repairing, to determine the laying of the surface can not cause damage to foreign substances, such as broken needle and other foreign body; 5. Geotextile connection must follow the following provisions: Under normal circumstances, the slope can not have a horizontal connection (connection along the slope The contours do not intersect with them), except where the patch is located. 6. If the use of suture, suture should be used with geotextile material the same or more than the material, suture should be anti-chemical UV material holding. Suture and geotextile should have a significant color difference in order to facilitate inspection. 7. Special attention to suturing during installation to ensure that no gravel in the soil or gravel cover is in the middle of the geotextile.
