COMPACTION SEGMENT DEVICE FOR REPAIRING METALLIC AND CONCRETE BASES OF HYDRAULIC STRUCTURES IN THE UNDERWATER ZONE AND AT THE VARIABLE WATER LEVEL Russian patent published in 2018 - IPC E02B1/00 E02B17/00 

FIELD: construction.

SUBSTANCE: invention is intended for use by organizations (legal entities) and/or individuals performing, in the underwater zone and at a variable water level, repair of constructions of hydraulic structures, namely a metal or concrete pile foundation of hydraulic structures of different cross-section. Compacting segment device consists of prefabricated metal segments, allowing to assemble the necessary device in terms of composition for work in underwater zones or in a variable water belt on vertical or inclined piles of hydraulic structures having different sections and consisting of metal or concrete. Each of the prefabricated metal segments is formed by a metal shell, removable vertical ballast chambers 1, connected to the compressor and providing positive buoyancy and the ability to repeatedly move the device vertically in the water, joint sealed joints 2, removable-mobile sealed assemblies that provide sealing at the interface of sections, central sections, allowing to ensure sealing at the interface of the device with a pile of the hydraulic structure. On the prefabricated metal segments, eyes for securing braces 7 are mounted. Water pump 8 for pumping water is placed at the top of the device. Control of ballast chambers 1 of segments is carried out from the auxiliary boat through the air-water hoses.

EFFECT: possibility of performing work in the underwater zone and at variable water level by means of a device without putting the hydraulic structure out of operation.
