SLOPE ATTACHMENT OF COMBINED STRUCTURE FOR PROTECTION OF COASTAL ZONES FROM WASHOUT Russian patent published in 2024 - IPC E02B3/12 

FIELD: construction.

SUBSTANCE: slope attachment of combined structure for protection of coastal zones from washout relates to hydraulic engineering and environmental construction. In the device, comprising in the base metal coarse-mesh 1, on top of which there is geotextile 2 attached to the metal rods of mesh 1, on which bags 3 filled with fertile vegetal soil are laid in staggered order, in the space between bags 3 up to the top local soil 5 is laid, and on top there is a continuous layer of flexible mattresses 6, flexible mattresses 6 are made of perforated drainage tubes 7 of cylindrical shape, wound around geomats and geogrid, wherein flexible mattresses 6 are laid in dense rows, starting from the foot of the slope, and are interconnected by means of a metal wire, on top of flexible mattresses 6, a gabion galvanized net 10 is stretched over the entire area, attached to coarse-mesh 1 of the base, at that, at the foot of the slope attachment along the channel part, flexible plates are arranged in the form of apron 11, which are made of volumetric geogrids 12, cells of which are filled with gravel and pebbles and are wrapped around gabion net 13 attached to metal rods of coarse-mesh 1 of the base.

EFFECT: reduction of labor intensity of slope fasteners manufacturing at increase of fastening operation efficiency.
