INNOVATIVE SPATIALLY POLYMER GRID (VERSIONS) Russian patent published in 2012 - IPC E02D17/20 E01C3/04 

FIELD: construction.

SUBSTANCE: innovative spatially polymer grid (ISPG) is designed to reinforce building structures and to strengthen weak bases of industrial and civil structures, as well as slopes of coastal lines and water reservoir beds. ISPG may find application when erecting aerodromes, road surfaces, strengthening slopes, arranging retaining walls and in other versions of usage in oil and gas, transport, hydraulic engineering sectors of construction, which require high and stable strength and durability indices of erected structures. A spatially polymer grid (SPG) with a cellular structure for stabilisation and reinforcement of soil surface, arranged from flexible strips, preferably from a low pressure polyethylene, arranged in several rows and joined to each other in a staggered order along the length of strips with the possibility to form a cellular structure as strips are stretched in a direction normal to their surface, and such structure will differ by the fact that strips are equipped with drain holes in the form of extended rectangles with semicircumferences on short sides, and besides, the strips are reinforced in a longitudinal direction by aramid or carbon threads at the following ratio of components in wt %: Aramide or carbon thread - 0.2-3, Low pressure polyethylene - balance.

EFFECT: higher bearing capacity and stability of geometric parameters of the structure, no deformation in soil structures reinforced with a ISPG, higher strength and increased service life of erected structures, higher drainage capacity of SPG, reduced cost of a spatially polymer grid, approximately.
