HYDRAULIC STRUCTURE NAVIGABLE PASS GATE Russian patent published in 1995 - IPC

FIELD: hydraulic engineering. SUBSTANCE: improved gate differs from known floating gate by design of body. Improved gate body has box-like pontoon with parallel longitudinal faces and box-like columns mounted on deck face in perpendicular relation with respect to pontoon longitudinal faces. Ballast sections of pontoon and columns, gate ballast system for receiving and pimping ballast from one group of sections into another group of sections allow vertical immersion and turning of gate relative to its longitudinal axis through 90 deg. to be effectuated. When gate is in turned position, it is disposed on bottom of navigable pass in operating state. In this case pontoon acts as closure member and columns oriented towards downstream wall act as pontoon strengthening members and pontoon supporting devices. When in inoperative floating position, with columns oriented upward, gate may be used as mooring construction. When in docking mode, gate may be used for docking ships and other vessels on pontoon deck between columns for preventive inspection and repairing of underwater part of ship and vessels. EFFECT: increased efficiency and wider operational capabilities. 24 cl, 4 dwg
