DIAMOND TYPE MULTI-AXIAL PLASTIC STRETCHABLE GEOGRID AND MANUFACTURING METHOD THEREOF

摘要

A diamond type multi-axial plastic stretchable geogrid comprises transverse bars and longitudinal bars; the transverse bars and the longitudinal bars form rectangular units with the joints thereof intersected; the rectangular units are provided with short bars therein; the short bars divide the rectangular units into the following shapes: two trapezoids, the upper base lines of the two trapezoids being coincident, the lower base lines being respectively coincident with two pairs of side lines of the rectangular unit, the top ends of the lower base lines of the trapezoids being coincident with the apexes of the rectangular unit, and the other two pairs of side lines of the rectangular unit form a triangle together with the slopes of the two trapezoids. Also provided is a manufacturing method of the diamond type multi-axial plastic stretchable geogrid.
