MOVABLE BARRAGE SECTION, SYSTEM FOR PROTECTION AGAINST FLOODING AND METHOD OF MOVABLE BARRAGE CREATION Russian patent published in 2004 - IPC

FIELD: hydraulic structures, particularly movable barrages.

SUBSTANCE: method of barrage forming involves creating barrage sections having two parallel spaced elongated inflatable tubes connected one to another by water-impermeable bridge; arranging elongated inflatable tubes on ground so that side wall of the first tube faces flooding area and the second tube oriented in opposite direction; inflating both tubes; poring ballast water on water-impermeable bridge so that with rising of flood water the first tube floats on flood water surface and rises to form barrier against flooding. Movable barrage system includes two spaced parallel elongated inflatable tubes connected one to another by water-impermeable bridge and arranged on ground so that side wall of the first tube faces flooding area and the second tube oriented opposite direction. Diameter of the first tube is less than diameter of the second tube. Outermost barrier sections may be provided with sealing means so that sealing means of one section is overlapped and connected with sealing means of adjoining section to form uninterrupted barrage.

EFFECT: possibility of easy and assemblage.
