ANTI-EROSION ATTACHMENT FOR PROTECTION AND RESTORATION OF DISTURBED LANDS OF THE ARCTIC ZONE Russian patent published in 2025 - IPC E02B3/12 A01B13/16 

FIELD: construction.

SUBSTANCE: invention relates to hydraulic engineering and environmental construction and can be used as protective fastening for restoration of eroded and disturbed areas of lands of the Arctic zone in the regions of the North and Far North. In the anti-erosion fixture, comprising a protective mesh and flexible mattresses of a cylindrical shape, made of perforated drainage pipes wrapped around with biomats and a geogrid, and laid in trenches, with a depth of up to 2/3 of their diameter, along the entire length of the eroded section, in gaps between rows of cylindrical mattresses on top of frozen soil throughout the area there are flat mattresses from two or three layers of geomat, on top of which bags are laid in dense rows filled with vegetal soil with addition of seeds of frost-resistant plants and shrubs. Bags are made of geotextile with diameter of 0.2-0.3 m and length of 0.8-1.0 m, and are connected to each other by means of rope knots, and on top of rows of cylindrical mattresses and bags with vegetable soil throughout the area and perimeter of attachment is covered with protective net and in some places is attached to base by means of stakes. To ensure germination and development of the root system of frost-resistant plants and shrubs and accelerated recovery of the turfed surface of the eroded area of the earth, fastening gaps from bags with vegetal soil between cylindrical mattresses are poured with water.

EFFECT: anti-erosion fastening can be most effectively used for protection and restoration of eroded and disturbed areas of reclaimed lands of the Arctic zone in the regions of the North and Far North.
