PROTECTIVE HYDRAULIC STRUCTURE Russian patent published in 2015 - IPC E02B7/00 E02B3/10 

FIELD: construction.

SUBSTANCE: protective hydraulic structure includes two closed flexible covers filled through nozzles with water or air, each of which is provided with two elastic side ribs located along generatrixes of the covers. The covers are connected to each other with neighbouring internal ribs of the covers. Closed flexible covers have different diameters and are connected at some distance from each other of at least three diameter of the cover of smaller diameter. Ratio of diameters of closed flexible covers is 1:2. To both external ribs and end walls of closed flexible covers there tightly attached is a flexible cover with a float in the form of a single flexible cylindrical closed cover provided with air supply nozzles and nozzles for filling its inside volume with water.

EFFECT: improving efficiency of the proposed quick-erected hydraulic structure of low specific weight; providing the possibility of its repeated installation and re-installation in different places with minimum labour costs.
