INNOVATIVE SEAMLESS GEOGRID MESH STRUCTURE FOR SOIL REINFORCEMENT, METHOD AND STORAGE FOR ITS RECEPTION Russian patent published in 2016 - IPC E02D17/20 

FIELD: construction.

SUBSTANCE: invention relates to field of construction, namely to structure of geogrids, and can be used to strengthen shorelines and river beds of water bodies, slopes, retaining walls cones bridges in oil and gas, transportation, waterworks construction and other industries. Preform for producing a seamless sheet of geogrid made of polymeric material in which incisions are made in form of segments of straight parallel lines of equal length L, as shown in Figure 1, arranged in rows (R₁, R₂, …R_N) offset line sections of adjacent rows along cuts. Adjacent slits in one row (R₁, R₂, …R_N) are at a distance S between ends thereof, ratio S/L = K1, where K1 is between 0.1 and 0.5. Sections of adjacent rows (R₁, R₂, …R_N) are at distance D from each other, ratio D/L = K2, where K2 is 0.1 to 0.7. At ends of sections provided with holes of oval or round shape.

EFFECT: technical result is to increase strength of lattice to break, reducing complexity of its manufacture.
