COASTAL FIXTURE FROM FASCINES AND GABION METS OF BIOPOSITIVE DESIGN Russian patent published in 2015 - IPC E02B3/12 

FIELD: construction.

SUBSTANCE: on a slope 2 heavy fascines 1 are laid in longitudinal and transverse strips to form square or rectangular cages of different size from 1 to 2.5 m. Heavy fascines 1 are joined to each other with the help of metal stainless steel nets and wires. Inside cages there is a polymer net 4 laid and fixed to heavy fascines 1, on top of the net there is a layer of light fascines 3 in tight rows wrapped on top with a gabion net 5. In the base of the slope at a certain distance from each other there are gabion mats 6 of prismatic shape, which are fixed to heavy fascines 1 of the slope fixture. On top of gabion mats 6 there is a reinforcement meshed frame 8 of segment shape, which is attached to rectangular rings 9, wrapped around gabion mats 6 at the distance from each other. The reinforcement frame 8 at the side of the slope with the help of ropes or reinforcement wires 10 is fixed in some areas to anchors 11, arranged in the slope 2 above the fixture. Such fixture may be used most efficiently at plain and hard-to-access sections of small rivers.

EFFECT: partial suppression of excessive energy of river course, even distribution of hydrodynamic loads of the course along the fixture, the fascine fixture works both as protective fixture and as drainage.
