Abstract
1312032 Cleaning tanks KONINKLIJKE MAATSCHAPPIJ TOT HET UITVOEREN VAN OPENBARE WERKEN "ADRIAAN VOLKER" NV 18 Jan 1971 [19 Jan 1970] 2438/71 Heading A4F [Also in Division E1] A hopper suction dredge has a suction pipe mouth which has a scraper secured to it and which contains one or more nozzles for directing one or more water jets transverse to the plane in which the scraper lies and on to ground lifted by the blade. Mouth 2 pivotally supports at 10 a visor-shaped flap 3 supporting scraper 4 and water jet nozzles 8 directing water jets in the direction of suction on to lifted ground 6. Visor 3 is pivoted about pivot 10 by adjustable locking member 11. In alternative embodiments, the jets are directed away from the direction of suction, and the scraper is situated near the front side of the flap, in the direction of dredge movement, and under the centre of gravity of the mouth.
