PROTECTIVE HYDRAULIC STRUCTURE Russian patent published in 2007 - IPC E02B3/04 E02B7/02 

FIELD: hydraulic structures adapted to protect shore object against natural disasters and to erect temporary barriers on water pool bottom.

SUBSTANCE: hydraulic structure comprises flexible cylindrical sealed shell to be filled with water. The shell is composed of two vessels touching each other. Each vessel is provided with two elastic side ribs extending along vessel generators. The vessels are connected with each other by adjacent inner ribs so that figure-of-eight structure is created. Opened flexible shell is fastened to one outer rib of figure-of-eight structure by lower edge thereof. Floats are arranged on upper edge of opened flexible shell. The floats are connected to outer rib by flexible tie members so that tie member length may be changed.

EFFECT: decreased time of structure installation and demounting due to reduced volume of water to be supplied in closed shell, reduced weight of structure components and increased hydraulic structure stability.
