STRUCTURE PROTECTING WATER INLET AGAINST DRIFTS Russian patent published in 1998 - IPC

FIELD: water- development works. SUBSTANCE: proposed structure includes water intakes of water inlet, baffle with vertical top face, trestle and drift warding away contrivance connecting head water and tail water. Given contrivance is manufactured in the form of number of tubes with suckling fixtures. Tubes are placed horizontally above level of annual depletion of water reservoir. Suckling fixtures are mounted for movement along trestle, dug below level of drifts and are away from water inlet by distance sufficient for transfer of large suspended drifts to bottom form of movement. Trestle bridges over approach to water intake. Baffle is arranged downstream of location of suckling fixtures. Washing holes are made under water intakes. EFFECT: simplified design, improved operational parameters. 2 dwg
