METHOD FOR ERECTING A RETAINING WALL OF A COMBINED STRUCTURE TO PROTECT COASTAL ZONES FROM EROSION Russian patent published in 2023 - IPC E02B3/06 E02B3/12 E02D29/02 

FIELD: engineering structures.

SUBSTANCE: retaining wall of the combined structure for protecting coastal zones from erosion refers to hydraulic engineering and environmental construction. In a method involving the creation of steps of layer-by-layer heavy fascias and gabion mattresses with drainage devices, according to the invention, the steps are arranged in a combined design, and for the construction of the first stage 1 and the second stage 2, heavy fascias 3 are used from bags with soil filler and a flexible shell, for which a geomat laid in 2-3 layers and tied in three places is used, and gabion mattresses 4 are made of layers of biomat 9 and perforated drainage pipes 10, laid in two lines in the middle of the biomat layers, on top of which a gabion mesh 11 is laid, providing gabion mattresses with 4 prismatic shape. On top of second step 2, on the slope, fastening from flexible mattresses 12 is provided, the filler of which is made of dense layers of geomat 6 laid along the slope of the slope. At the sole of first stage 1, along the outer row of heavy fascies 3 and the reservoir bed, flexible slabs are mounted in the form of apron 13, which are made of volumetric geogrids 14, filled with gravel and pebbles and wrapped around with a gabion mesh.

EFFECT: reliable protection of coastal zones in foothill and flat areas.
