METHOD FOR CONSTRUCTION OF ANTI-EROSION LINING USING FLEXIBLE MATTRESSES Russian patent published in 2023 - IPC E02B3/00 

FIELD: hydraulic engineering.

SUBSTANCE: in the method of erection of anti-erosion lining including laying of flexible mattresses 1 and protective mesh 6, flexible cylindrical mattresses 1 are made of perforated drainage pipes 3, wrapped in biomats and geogrid and laid in rows across the slope in trenches located at a distance of 10-15 m from each other buried to the depth of 2/3 of their diameter and backfilled on the sides with soil along the entire length of the eroded area. Between the rows of flexible cylindrical mattresses 1, flat mattresses from 2-3 layers of geomats 5 are laid over the entire area. On top of the rows of flexible cylindrical 1 and flat mattresses 5, over the entire area of the eroded section of the slope and partially covering the turfed ground surface as well, a protective mesh 6 is stretched along the entire perimeter of the lining and attached in some places to the foundation surface with fiberglass or metal stakes 7.

EFFECT: high degree of flexibility and water permeability, germination of green plants and accelerated recovery of small eroded areas of sloping land; protection and restoration of eroded areas of sloping lands; particularly effective in hard-to-reach mountain and foothill recreational and protected areas.
