BATTER DRAINAGE OF BIOPOSITIVE DESIGN Russian patent published in 2010 - IPC E02B11/00 

FIELD: construction.

SUBSTANCE: batter drainage of biopositive design comprises multi-layer filter made of flexible biopositive mats connected to each other. Mats are made of meshy shells and draining filler, which is arranged from layers of light fascines inside shells. Lower layers of fascines are laid normally towards direction of filtration flow, and upper layers - along with its direction. The mats themselves are in some areas pierced with metal wire. Flexible biopositive mats in areas of their connection on top are fixed with the help of reinforcement wire to concrete anchors arranged in lower slope above level of filtration flow and at the distance to each other. At the bottom near foot of lower slope flexible mats are on top loaded with heavier mats, meshy shells of which contain several layers of bags with local and vegetable soil below, and on top they contain tight layers of light fascines made of cane.

EFFECT: invention makes it possible to improve operational reliability of structure and helps to recover green zones near water edge in lower reaches of soil structures.
