PORTABLE FLOOD CONTROL BARRIER SECTION AND FLOOD CONTROL BARRIER Russian patent published in 2006 - IPC E02B7/00 

FIELD: hydraulic structures, particularly barrages or weirs.

SUBSTANCE: barrier section is adapted to be installed on ground and creates barrier, which restrains flood water. Barrier section comprises wall hingedly connected to base by the first end and flexible or rigid clamp. Hinge connection provides wall rotation from substantially horizontal position into elevated position. Flexible or rigid clamp extends from the base to wall from section side contacting with water and prevents wall displacement from elevated position. Barrier section comprises sealing member, which is located between ground surface and section installed in elevated position. Before bringing barrier section in contact with water the barrier section is adapted to apply sealing pressure to sealing means, wherein the sealing pressure exceeds that exerted by section weight. Flood control barrier includes a number of above portable sections connected with each other by means of additional watertight sealing means in longitudinal barrier direction.

EFFECT: elimination or minimization of water leakage between barrier sections or between barrier and ground, reduced barrier storage size.
