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

FIELD: construction, road engineering.

SUBSTANCE: invention relates to hydraulic engineering and nature conservation construction, and may be used as erosion-preventive structures used in piedmont and mountain areas of protected natural reserves. The method includes erection of a multi-stage drop. Structure stages are arranged in the form of bottom thresholds from rows of heavy fascines of biopositive design. Thresholds are laid across a channel and normally to direction of 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 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. A gabion net is tightened on top of the light fascines and is attached to slopes and to a metal net of heavy fascines.

EFFECT: higher efficiency of structure operation and recovery of ravines and other washed sections of eroded lands.
