Multi-axial integral geogrid for stabilizing aggregates
The patent US12036722B2 outlines a method for creating a multi-axial integral geogrid, which involves several key steps. Initially, a polymer sheet is provided, followed by the introduction of a patterned plurality of holes or depressions. The polymer sheet is then biaxially oriented, resulting in interconnected oriented strands and partially oriented junctions that form a repeating pattern of outer hexagons. These hexagons contain an array of openings and are supported by ribs that extend inwardly, creating smaller inner hexagons with open centers. The design incorporates three distinct geometric configurations—hexagonal, trapezoidal, and triangular—repeating throughout the geogrid. The method also specifies that the polymer sheet should have an initial thickness ranging from about 3 mm to 10 mm.
Additionally, the patent describes a method for reinforcing and stabilizing composite soil structures by embedding the multi-axial integral geogrid within particulate material. The geogrid's design allows for the inner hexagons to deflect during compaction, enhancing its adaptability. The oriented strands are characterized by an aspect ratio greater than 1.5, and the geogrid features three continuous linear strands that are evenly spaced at 120° intervals. The openings in the geogrid are designed to provide a distribution of individual aperture areas between approximately 475 mm² and 800 mm². This innovative approach aims to improve the structural integrity and performance of soil structures, making it a significant advancement in geotechnical engineering.
