Horizontal mechanically stabilizing geogrid with improved geotechnical interaction
Aspects of a geogrid system and method for improving substrate interactions within a geotechnical environment is disclosed. 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, wherein the geogrid comprises a heightened aspect ratio with a patterned structure of engineered discontinuities and a plurality of strong axes. The combination of elements provides for a system and method of stabilizing soils and aggregate, by resisting lateral movement from the strong axes, and trapping particles in the patterned structure of engineered discontinuities.
1. A geogrid for increasing confinement of soils and aggregate, comprising:
an outer hexagon made of continuous ribs and primary nodes;
an inner hexagon made of secondary nodes and non-continuous ribs, wherein the non-continuous ribs form patterned discontinuity by terminating at an opposing inner hexagon;
a polymeric layer forming a part of the outer hexagon and the inner hexagon;
a compressible cellular layer forming a part of the outer hexagon and the inner hexagon; and
a heightened aspect ratio at the primary nodes and the secondary nodes in relation to the continuous ribs and the non-continuous ribs.
2. The geogrid of claim 1 , wherein the primary nodes are larger than the secondary nodes.
3. The geogrid of claim 1 , wherein the secondary nodes are more pliable than the primary nodes.
4. The geogrid of claim 1 , wherein the inner hexagon forms a void region to nest aggregate.
5. The geogrid of claim 1 , wherein the compressible cellular layer forms a top layer and a bottom layer of the outer hexagon and the inner hexagon.
