ELEMENTS AND METHODS FOR REINFORCING SOIL-LIKE MATERIALS

摘要

Small discrete structural reinforcing elements (12) are disposed within soil (14) or other aggregate material for stabilizing the same. Each reinforcing element is a unitary plastic member having a common hub (16) from which radiate a plurality of arms (18). The ends of the arms have enlarged gripping members (20) which are each larger than the cross section of its arm. These gripping members are shaped as cubes, spheres or are irregular shapes. The surface of the gripping members, in one embodiment, is roughened and in another is scored or provided with dimples.
