摘要:
The invention relates to a geotextile composite for applications in civil engineering. It comprises at least one textile ply (401) and further comprises at least one reinforcing member (402, 403) such as a grid or technical wires extending into one or two directions, wherein said textile ply (401) is obtained by weaving or knitting in order to provide ground draining, filtration, reinforcement and/or separation properties. The textile ply is solidly connected to the reinforcing member using binder yarns (404) which pass alternatively from one face of the composite geotextile to the other.
摘要:
Device for laying geosynthetics consisting of a guiding mechanism 9 that is arranged on the body of a vehicle in a perpendicular position with respect to the subsoil and comprises a carrying part 12 with straight guiding rails 13, curved adjusting rails 14 and press-on sheaves 10. The adjusting rails 14 have a curved upper portion extending from a preceding straight portion, thus forming a funnel 15 having its inlet 17 in the widest section, the width of the inlet 17 being equal to the total width of the strip 2 and the composite tip 3 and the spacing 16 between the straight portions of the rails 13, 14 being uniform. The adjusting rail 14 is formed as a lead-in profile having its lowest point at the upper edge of the carrying part 12 and continuously increasing in height up to the transition into the corresponding straight portion.
