UNDER-CHANNEL FILTER WATER INTAKE OF BUCKET STRUCTURE Russian patent published in 2020 - IPC E02B9/04 E03B3/32 

FIELD: construction.

SUBSTANCE: invention relates to hydraulic engineering, namely to water intake structures used for water intake on mountain and foothill areas of rivers with complex geological conditions. Under-water filtering water intake comprises water-collecting element and filtering water intake in river bed. Water collection element is made in the form of a rectangular cross-section ladle and is installed across the river bed in the place of no washout, in which there is a filtering water receiver made of perforated pipes of equal length. Initial section of pipes is fixed with reinforced concrete. Gravel is laid around the pipes, rock-by-layer is placed above the level of bed bottom. Inside the pipes there installed are flushing tubes of smaller diameter with cylindrical nozzles, which are laid in the centre of perforated pipes, the wellhead part of which enters the chamber of the water-collecting well.

EFFECT: technical result is higher reliability of bucket under-water inlet filter water intake.
