FIELD: hydraulic structures, particularly sediment base gates, sand sluices and structures for arresting waterborne material, namely water cleaning devices used in water intake for economical needs. ^ SUBSTANCE: sump comprises inlet regulator sluice, working chamber, outlet regulator sluice with flushing gallery and pressure slice spillway installed in outlet regulating sluice in front of working gate. Impact baffle is installed behind working gate in slot provided with emergency gate installation. Pressure sluice spillway may extend in vertical direction or may be inclined and made as chute. ^ EFFECT: increased efficiency of water cleaning due to pressure sluice spillway usage, which provides water taking from upper clean water layers inside sump. ^ 3 cl, 5 dwg |
