ANTIEROSION STRUCTURE OF BIOPOSITIVE DESIGN FOR RECOVERY OF RAVINES Russian patent published in 2015 - IPC E02B3/00 

FIELD: construction.

SUBSTANCE: antierosion structure of biopositive design contains ground sills from rows of heavy fascines and flexible mattresses from light fascines. The ground sills from heavy fascines are made in the form of reinforced steps. The fascines are laid layer-by-layer in rows alternating lengthways and crossways. Rows of fascines are located inside the reinforcing lattice framework. In each step the first layer of fascines is laid in dense rows across the bed width. The second layer of fascines is laid in the flow direction and normally to rows of the first layer. The uppermost row of heavy fascines of the first step is reliably connected with the first layer of the second step. The second and subsequent steps are erected similar to the first step. The upper row of fascines of the first step is connected with the first layer of the second step. All steps are joined among themselves using the reinforcing lattice frameworks. Heavy fascines consist of soil filler and mesh shell. The fascines are connected among themselves by gabion mesh and wire.

EFFECT: improvement of structure efficiency at recovery of deep ravines and gullies.
