DEVICE FOR STORAGE OF BOTTOM ALLUVIUMS Russian patent published in 2016 - IPC E02B7/06 E02B3/02 

FIELD: hydraulic engineering.

SUBSTANCE: invention relates to hydrotechnical construction, in particular, to installations for storage of bottom alluviums, generated as of the soil dumps along shore areas during cleaning of small rivers, ponds, channels and other water bodies from bottom of alluvial deposits. Installation for storage of bottom alluviums includes sections of alluvial dumps 4, placed in the meander zone, diversion dyke 5 made in the form of a guard along the whole perimeter of sections of alluvial dumps 4, and water discharge channel 14. Installation is additionally equipped with water-discharge diversion dyke 6, water-collecting channel 12, open tank 13, horizontal transverse drain elements 9, horizontal longitudinal drain elements 10 and vertical drain elements 11. Water discharge diversion dyke 6 is arranged in perimeter of diversion dykes 5 between the most remote from water body sections of diversion dykes 5 and constructed with low relative to other diversion dykes 5 height with possibility of overflow of water excess through it from sections of alluvial dumps 4 in water intake channel 12. Vertical drain elements 11 are located in a body of stored bottom alluviums and linked with horizontal transverse drain elements 9 or horizontal longitudinal drain elements 10 and are arranged in the base of sections of alluvium dumps 4. Horizontal longitudinal drain elements 10 are made linked with water channel 12 with the possibility of ingress of water from them from water saturated body of stored bottom alluviums into water intake channel 12.

EFFECT: technical result is reduction of time for creation of installation for storage of bottom alluviums, reduced costs for its erection, increased efficiency of used construction equipment during its construction and prevention of silting of riverbed downstream from the point of creation of installation for storage of bottom alluviums.
