PROTECTIVE FLEXIBLE SECTIONAL DAM Russian patent published in 2013 - IPC E02B3/10 E02B7/02 

FIELD: construction.

SUBSTANCE: dam comprises contacting flexible cylindrical closed shells, every of which is equipped with two elastic ribs arranged along forming shells. With adjacent internal ribs the shells are combined into "eights". To one of external ribs of the "eight" there is a non-closed flexible shell fixed with its longitudinal edge, and flexible links are connected to another external rib. At the same time "eights" are formed into rows, which are arranged above each other to form a truncated pyramid, on the comb of which there are at least two shells, and in each subsequent lower row there is one shell more than the number of the upper row shells. All rows of "eights" are combined to each other by reinforcement belts in the form of flexible links fixed on all external ribs of closed shells making the pyramid. The non-closed flexible shell serves as an antiglare screen and is made of a fabric cloth arranged on a part of a pyramid protruding above the water surface level. The non-closed flexible shell is rigidly fixed with the second longitudinal edge to the external rib of one of underwater rows of "eights" at the side surface of the pyramid opposite to location of fixation of the first longitudinal edge. All closed shells and shell-to-shell space between them are filled with a hydraulic sand mixture.

EFFECT: higher reliability and improved operational characteristics of a structure.
