METHOD FOR ERECTING ANTI-EROSION FASTENING OF BIOPOSITIVE STRUCTURE Russian patent published in 2021 - IPC E02B3/00 

FIELD: hydraulic engineering, nature protection.

SUBSTANCE: invention relates to hydraulic engineering and environmental protection construction and can be used to protect and restore small and shallow eroded areas of sloping lands in the foothill and mountain zones of protected natural territories. The method for erecting an anti-erosion fastening of a biopositive structure includes laying flexible mattresses 1, light fascines 2 and a protective mesh. Flexible cylindrical mattresses 1 are arranged in rows at a distance of 10-15 m from each other along the eroded section of the slope and normally to the direction of the surface water flow. Cylindrical mattresses 1 are made with a diameter of 30-35 cm from light fascines 2 and drainage pipes 3 wrapped in a geogrid. Light fascines 2 are made with a diameter of 10-15 cm in the form of bundles of ripe reeds, and drainage pipes 3 with a diameter of 3-5 cm are made of polymer or fiberglass materials. In the intervals between the rows of flexible mattresses 1, light fascines 2 are laid in dense rows parallel to them. On top of the rows of flexible mattresses 1 and light fascines 2, a protective mesh 5 is covered over the entire area and attached in places to the surface of the fastening area with metal spiles 6. The mount assembled in this way has a high degree of flexibility and water permeability, ensures the germination of green plants and accelerated restoration of small eroded areas of sloping lands.

EFFECT: flexible attachment of the biopositive structure is designed to protect and restore eroded areas of sloping lands, it is especially effective in conditions of inaccessible mountain and foothill recreational and protected areas.
