These photo’s are made at Sassevaart near Terneuzen, where we are emptying tubular piles for the construction of the Nieuwe Sluis (North Sea Port).
The Bell 100 equipped with a double cutter head has a diameter of 1,1 meter and is lowered into the piles to pump the sand, clay and debris out. Because the pump is equipped with a water jet ring around the center the pile wall gets cleaned simultaneously. 15 Meters of soil is dredged at a rate of 0,5 hour per pile. The work will finish soon with already 120 piles having been emptied and cleaned at this moment.
