The specific embodiment
The utility model provides a kind of gentle malleability single, double preferably to the plastics compound geogrid, similar with traditional product, geo-grid is that the band by longitudinal and transverse two directions is cross-linked and forms, and different is, in the utility model, be provided with reinforcing rib in the band and form the reinforcement band.
Referring to shown in Figure 1, be the cross-section cutaway view of used reinforcement band in the utility model.This band 1 center is a reinforcing rib 11, and reinforcing rib 11 peripheries are enclosed with one deck crust 12; The thickness of reinforcement band 1 is 1mm-5mm, and the cross section is wide can be in the 8mm-15mm scope, and cross sectional shape can be rectangle (as shown in Figure 1) or flat ellipse, is as the criterion so that process and be welded to each other.In the utility model, crust 12 adopts the vinyon material, and reinforcing rib 11 adopts glass fiber or basalt fibre material, and this reinforcement band 1 adopts ripe plasticizing extruding-out process to make, and then again by heating, be welded into mesh grille.
Use the above reinforcement band of introducing, it is single, double preferably to the plastics compound geogrid to adopt advanced supersonic welding connection technology that interconnection node firm welding is made the gentle malleability of the utility model.
Referring to Fig. 2 A and Fig. 2 B, two-way plastics compound geogrid is that the composite reinforced band 1 longitudinal and transverse cross arrangement of several high strength plastics is become 90 °, constitute square net structure, shown in Fig. 2 B, laterally band 1A is all following, longitudinal band 1B is all last, and laterally whole interconnection nodes of band 1A and longitudinal band 1B are firm with ultrasonic bonding.So, can obtain square mesh, the mesh length of side is 50-80mm, and fabric width is the two-way plastics compound geogrid of 6m, and certainly, the length of grid can be determined according to actual needs.Two-way plastics compound geogrid can bear hot strength more than the 260KN/m in longitudinal and transverse two directions.
