METHOD FOR FORMING THREE-DIMENSIONAL LATTICE STRUCTURE MADE OF PLASTIC STRIPS Russian patent published in 2021 - IPC E02D17/20 

FIELD: construction industry.

SUBSTANCE: invention relates to the field of construction and can be used to strengthen slopes, bridge cones, inclined bases of highways, industrial and construction sites, as well as coastlines and water channels. The method for forming a three-dimensional lattice structure made of plastic strips is characterized by the fact that strips are cut out of sheet material, on which periodically repeating slots are formed. When cutting sheet material into strips, the cutting line is performed in the form of a periodically repeating trapezoidal cutout. Next, the longitudinal and transverse walls are formed by superimposing strips on each other. The trapezoidal cutouts of the lower strip form holes for beams and pipes with the trapezoidal cutouts of the upper strip. The longitudinal walls are displaced relative to the transverse walls by an amount equal to half the height of the strip, and fixed with slots.

EFFECT: improved quality of filling individual cells of the geogrid with fluid compositions and reduction of production waste when forming holes in the geogrid body.
