METHOD TO CREATE ANTI-FILTRATION COVER OF CANALS AND WATER RESERVOIRS WITH STEEP SLOPES Russian patent published in 2013 - IPC E02B3/16 

FIELD: construction.

SUBSTANCE: method includes laying of a protective cover from mattress gabions and a water-impermeable anti-filtration element from geomembrane. Besides, on top of the geomembrane a protective pad is arranged from geotextile, preventing damage of the geomembrane during laying and filling of gabions and also during operation. Mattress gabions are laid onto the protective pad from geotextile with their fixation on steep slopes with the horizontal equivalent of 1:2-1:1.5 with the help of synthetic ropes fixed to metal stands arranged on the slope edge. Possibility is provided to use mattress gabions as a protective cover of anti-filtration liners in canals and water reservoirs with steep slopes with the horizontal equivalent of 1:2-1:1.5 without damage to water impermeability of the anti-filtration element and elimination of water losses via the anti-filtration lining.

EFFECT: increased operational reliability, safety and efficiency of a cover.
