- the GEOWEB type geogrid is widely known from the prior art for reinforcing slopes, made in the form of ribbons made of polymeric material connected to each other in a checkerboard pattern with a predetermined pitch, fixed on the slope in an extended position to form diamond-shaped cells (see RF patent RU2152479 , E02D17 / 20, 2000 g).
- slotted holes are made mainly of a segmented shape (a linear shape is also allowed) in the form of rows with the displacement of adjacent rows relative to each other (see RF patent RU 2090702, 09.20.1997).
- reinforcing elements in the form of thickening zones can be made.
- a geogrid is obtained by stretching a preform to form a volumetric cellular structure. The disadvantage of this workpiece is that when it is stretched, plastic deformation of the sheet material occurs, which can lead to uneven geogrid.

- the geogrid is made of several blanks forming sections of the grating and interconnected by ultrasonic welding or metal clips,
- the geogrid is configured to fill the cells with fillers in the form of sand and / or crushed stone, and / or peat and sand mixture and / or concrete.
- the geogrid additionally has a substrate of geotextile material.
- FIG. 1 shows a workpiece for producing a seamless geogrid
- FIG. 2 shows a general view of the section of the workpiece
- FIG. 3-5 show embodiments of the cut zone of the workpiece
- FIG. Figure 6 shows the design of a seamless geogrid (blanks in a stretched state).
- the claimed workpiece for obtaining a seamless geogrid is made in the form of a flexible sheet material (1), in particular, a polymeric material, a fabric based on chemical fibers (carbon fiber, fiberglass) or another type of material.
- a flexible sheet material (1) in particular, a polymeric material, a fabric based on chemical fibers (carbon fiber, fiberglass) or another type of material.
- cuts 2 were made (see Fig. 1), forming cells.
- These sections (2) are formed by the central part (3) in the form of a straight line segment and two end parts (4) in the form of lines having the shape of an arc and providing a rounding (rotation) of the ends of the sections (2) (see Fig. 2-5) .
- This configuration allows the most optimal redistribution of loads in the geogrid in the region of the end sections of the sections, and, as a result, increases the tensile strength of the structure.
- the end parts (4) are configured to rotate the cuts through an angle of 90 °, i.e. the end part has at the end a section perpendicular to the central part (3).
- the end parts (4) are configured to rotate the cuts through an angle of 90 °, i.e. the end part has at the end a section perpendicular to the central part (3).
- the central parts (3) of sections (2) are arranged in rows (R R2, ... R N ) with the displacement of the cut lines of adjacent rows along the direction of the cuts (see Fig. 1).
- the end parts of the cuts are preferably directed in one direction.
- thickening zones (5) are made (see Fig. 3). These thickening zones (5) can have a circle or oval in plan (in longitudinal section). Other shape variations are also possible.
- additional thickenings (6) can be made in the blank in the region of the central part (3) of the cut (2).

- Sheet (1) can be made of colored material, which will allow the use of a stretched geogrid for advertising or informational purposes.
- the cuts (2) of the sheet material (1) are preferably performed using laser cutting technology, which gives the structure additional hardening due to the flashing of the edge of the cut and, thereby, the elimination of microdamage on the edge. It is also possible to perform cuts (2) by cutting with a stamp.
- the transported sheet of the workpiece can be wound into a two-layer roll together with geotextile material forming the substrate (1 1) for the geogrid (see Fig. 6), and the geotextile has small folds, which allows it to stretch when the strip is stretched so that it was completely flattened when installing a geogrid on a slope.
- a geogrid is obtained from one or more of the aforementioned workpieces by stretching (preferably without plastic deformation) in the direction perpendicular to the lines of the central part (3) of the sections (2) to obtain a volumetric cellular structure in which geogrid cells formed upon opening the workpiece are connected by necks (10) ( see Fig. 6) In this case, the ends of the grating are fixed on the ground using anchors.
- the extreme openings of adjacent sections are aligned with each other and cables are pulled through them that connect adjacent sections and simultaneously fix the geogrid. It is also possible to connect the section using ultrasonic welding, metal clips or other connecting elements.
