SEAMLESS GEOGRID WITH CELLULAR STRUCTURE TO REINFORCE SOIL AND BLANK FOR ITS PRODUCTION Russian patent published in 2016 - IPC E02D17/20 

FIELD: construction.

SUBSTANCE: invention relates to construction, namely, to geogrid structures, and can be used for reinforcement of coastal lines and beds of water bodies, slopes, bridge cones, retaining walls in oil and gas, transport, hydraulic engineering and other industries of construction. Blank for producing seamless geogrid is made of flexible sheet material, in which there are incisions, having a central part in the form of a section of straight line and two end parts in the form of arc. At that, the central parts of the incisions are arranged in rows (R₁, R₂, … R_N) with an incision lines offset of adjacent rows along the direction of incisions.

EFFECT: technical result consists in improvement of the geogrid tear strength, reduction of its factory labor hours.
