EROSION-PREVENTIVE STRUCTURE OF BIOPOSITIVE DESIGN Russian patent published in 2012 - IPC E02B3/00 

FIELD: construction.

SUBSTANCE: erosion-preventive structure is arranged in the form of a multi-staged fall. Near fall stages there are several bottom sills arranged from rows of heavy fascines of biopositive design laid across a channel and normally to the direction of a surface water flow. Thresholds from heavy fascines are arranged at a certain distance from each other along the entire washed section of the ravine, and are made of three or more rows laid tightly into a horizontal layer of heavy fascines. Along coastal slopes of the ravine above the top of fascine thresholds, light fascines are laid in parallel rows as one layer to the level of the matted ground surface and in direction of the water flow, and on top of those there is a gabion net attached to slopes and to a metal net of heavy fascines.

EFFECT: invention provides for recovery of ravines and other washed sections of eroded lands.
