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

FIELD: construction.

SUBSTANCE: for implementation of the method of erection of antierosion structure of biopositive design the ground sills are laid. The ground sills are made in the form of reinforced steps from heavy fascines. 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. All steps are joined among themselves using the reinforcing lattice frameworks. Along coastal slopes above the steps the light fascines are laid. Light fascines are laid by parallel rows in one layer up to the level of high waters. From above rows of light fascines are wrapped by gabion mesh. The mesh is fixed to the slope and the reinforcing framework. In the end part of the first step across the direction of water flow at least three rows of heavy fascines are laid.

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