THREE-DIMENSIONAL GEOGRID FOR REINFORCING SLOPES

摘要

The invention relates to the field of construction, and more particularly to designs of three-dimensional geogrids, and can be used for reinforcing slopes in the oil and gas industry, the transport industry and the hydraulic engineering industry, and in other sectors of construction. The present geogrid comprises at least one element formed by a sheet of a polymer material with slits formed therein which are substantially in the form of portions of straight lines of equal length arranged in rows such that the slits of adjacent rows are offset from one another in the longitudinal direction. When the edges of the slits are moved in mutually opposite directions, a cell is formed having a front wall and a rear wall. Said at least one element is formed under the condition: (I), where d is the distance between the outer surface of the rear wall of the cell and the outer surface of the front wall of the cell; and h is the distance between rows in which the slits are not offset from one another. The invention increases the tensile strength of the geogrid while at the same time providing for ease of manufacture and efficiency of use.
