COMPOSITE RETAINING WALL Russian patent published in 2005 - IPC

FIELD: hydraulic structures, particularly for river or channel banks and slopes consolidation.

SUBSTANCE: wall includes gabions formed of net and stones and laid in layers. Gabions are made as parabolic cylinders oriented transversely or along flow direction and connected one to another so that gabion ridges of upper layers are offset relative that of lower ones to which they are connected. Wall is covered with concrete from one side. Parabola in the base of parabolic cylinder is described by the following equation: Y = (4·h_g·X²)/B_g , where X and Y are parabola abscissa and ordinate, h_g and B_g are correspondingly gabion width and height, here B_g = (2 - 4) h_g. Wall may be reinforced with reinforcing cage from another side. In particular cases net may have cross-section of stepped shape with decreasing steps width in upward direction or L-shaped cross-section.

EFFECT: increased reliability, reduced cost for foundation building, increased service life.
