METHOD FOR ERECTION OF SLOPE FIXATION OF BIOPOSITIVE STRUCTURE Russian patent published in 2009 - IPC E02B3/12 

FIELD: construction.

SUBSTANCE: invention is related to hydrotechnical construction of coast-protecting structures in eroded beds of rivers and channels. Method for erection of flexible slope fixture of biopositive structure includes installation of flexible mats along bed coasts on base. In the beginning metal wires are tightened in base to create wide-meshed grid. Geogrid is fixed on top of wide-meshed grid, and it has pockets located in parallel rows at a distance from each other. Pockets are filled with fertile soil with addition of seeds of perennial herbs and bushes with developed root system. In gaps between rows of pockets local or stone soil is laid to the level of pockets bulges top. Light fascines are laid in tight rows on top of soil layers and pockets. Gabion grid is stretched on top of fascines layer and is fixed to metal wires in base. Wide-meshed grid in base is made of galvanised wire with diameter of 4-6 mm and fixed to anchors, which are arranged in slope above the fixture and at a distance from each other. Light fascines with diameter of 10-15 cm are made of dry cane with length of 1.7-2.2 m.

EFFECT: increased efficiency and biopositivity of structure, reduced material expenses for construction.
