International Classification:

E02D 17/20
E02D 3/00

Abstract:

Aspects of a geogrid system for improving substrate interactions within a geotechnical environment is disclosed. In one aspect features of a geogrid system aid in trapping and restraining aggregate and soil. In one aspect a geotechnical environment is configured with a horizontal multilayer mechanically stabilizing geogrid. In said aspect the geogrid is extruded with a polymeric material and a compressible cellular layer. In said aspect, the horizontal multilayer mechanically stabilizing geogrid is comprised of either a cap or a core of polymeric material or is further comprised of at least one compressible cellular layer configured to the polymeric material. Further, the horizontal multilayer mechanically stabilizing geogrid is configured with a triangle or triaxial geometry with patterned discontinuities and a plurality of strong axes. Said configuration increases soil and aggregate trapping while reducing polymeric use.

Abstract:

A monolayer multi-axial integral geogrid suitable for stabilizing aggregate includes a plurality of interconnected oriented strands and partially oriented junctions forming a repeating pattern of outer hexagons having an array of openings therein. Oriented ribs extending inwardly from each of said outer hexagons support and surround a smaller inner hexagon having oriented strands thus forming a plurality of trapezoidal openings and a single hexagonal opening. The oriented strands and partially oriented junctions of the outer hexagons form a plurality of linear strong axis strands that extend continuously throughout the entirety of the geogrid and form additional triangular openings. The geogrid thus includes three different repeating geometric shapes. The inner hexagons preferably also can move up and down, out of the plane of the geogrid. The multi-axial integral geogrid thus provides a geometry that can better engage with, confine and stabilize a greater variety and quality of aggregates.
