Abstract

1365023 Suction dredging BALLAST-NEDAM GROEP NV 28 Sept 1972 [28 Sept 1971] 44911/72 Heading E1F A suction dredger comprises a pump 4 connected to a conduit 3, 4 discharging into a hopper 2 and having a suction head 6 which is trailed over a submerged surface 8 and is provided with a flap 12 adjusted in dependence on directions from a desired value of the flow rate in the conduit 4 as measured by means 15 to vary the gap 14 between the head 6 and the surface 8. Material 10 ahead of the head is fluidised by water ejected from a nozzle 27.
