CHUTE Russian patent published in 2004 - IPC

FIELD: hydraulic structures, particularly solidifying erosive or sagging ground.

SUBSTANCE: chute comprises inlet, water-pass and outlet parts having trapezoidal cross-sections, formed of gabions filled with stones and laid on prepared base made as inverse filter. Outlet part is made as water apron. Inlet, water-pass and apron parts are connected one to another and are not separated one from another by structural joints. Above parts are created of semi-cylindrical gabions so that gabion ridges face upwards and extend transversely to longitudinal axis of water flow. Gabions are formed by connecting upper and lower nets placed in water flow direction with the use of wires and by filling gap between nets with stones. Cavities defined between semi-cylindrical gabions and having curvilinear triangular cross-section with apex facing downwards are filled with concrete so that functional joints are created along gabion ridges. Inlet part adjoining water inlet channel and outlet part end are embedded in ground.

EFFECT: increased efficiency and operational reliability, extended service life.
