METHOD FOR GABION FASTENING DEVICE BUILDING Russian patent published in 2005 - IPC

FIELD: hydraulic building, particularly for river and channel banks consolidation.

SUBSTANCE: method involves laying gabions filled with stones on prepared base located on slope along river bed. Gabions are made as gabion mats consist of connected elliptical tubular members. Tubular member bases are described by the following equation: (4·X²/B2g

)+(4·Y²/h2g)=1, where X, Y are abscissa and ordinate of parabola defining tubular member base; B_g and h_g are gabion width and height correspondingly, B_g = (1 - 2)h_g. Gabion mats are preliminarily made with the use of matrixes filled with stones and made as two nets, namely upper and lower ones. Neighboring tubular members are sewed up in straight line by connection wire. Gabion mats are connected one to another to form single unit having apron. Apron is anchored to slope. Connection wire is twisted by wire twisting means. Gabion mats may be laid on slope with longitudinal or transversal tubular members orientation relative stream direction. In particular cases gabion mats are laid on slopes so that tubular member orientations alternate in staggered order. Gabion mats also may be laid on slope on gravel base having thickness of h_b > h_g/2, where h_b is gravel base height, h_g is gabion height.

EFFECT: increased efficiency and reliability of slope protection against erosion, increased service life.
