FIELD: building.
SUBSTANCE: bank protection structure includes a bulked soil water stop and flexible dikes consisting of separate blocks divided by structural control joints. The blocks are shaped as triangular prisms with a rib oriented upward and made hollow, with a triangular drilling inside and perforation on walls. To join the blocks and make them capable of rotating about each other, their fundaments are fitted with loops fixed by means of a bonding wire in the process of mounting. To fix a rotation angle of the blocks, upper loops, which are also fixed by means of a wire in the process of mounting, are placed on them. The blocks thickness ranges from 0.5 m to 2.0 m with bank erosion decreasing. The flexible dikes are installed transverse to moving flow, at the angle 15°-30° to its transverse axle. The distance between them depends on the flexible dikes length. To protect root section of the flexible dikes from erosion, a water stop is covered with slope fastening with mesh grid.
EFFECT: improved exploitation reliability of bank protection structure and decreased labour intensity of its construction.
