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

FIELD: construction.

SUBSTANCE: invention relates to hydrotechnical and environmental construction for protection of coastal zones from erosion and can be effectively used on lowland hard-to-reach sections of small rivers for protection of coastal zones from erosion by flood flows. Method involves laying along the banks of the riverbed on a base of coarse-mesh metal mesh 1, geotextile 2, bags 3, filled with fertile vegetal soil, and local soil 5 in the space between bags 3 to their top on the base, on top of which a continuous layer of flexible mattresses 6 is laid. Flexible mattresses 6 are made of cylindrical shape from perforated drain pipes 7, which are wrapped around with geomats and geogrid. Flexible mattresses 6 are laid in dense rows, starting from the foot of the slope, and connected to each other with the help of metal wire. Above flexible mattresses 6, gabion galvanized net 10 is covered over the entire area, attaching to the metal rods of coarse-meshed mesh 1 of the base. At the foot of the slope attachment along the riverbed part, flexible plates in the form of apron 11 are arranged, made of geogrids 12, which are filled with gravel and pebbles, and wrapped around in gabion net 13.

EFFECT: method of erection of slope attachment of combined structure provides reduction of labour intensity of slope attachment manufacturing at increase of attachment efficiency.
