Abstract

PURPOSE: To enable a continuous dredging of sludge, earth and sand and the like without dredging up them togetherwith water, by feeding desired pressured air after embedding a sealed rudder into a dirt bed, and by revolving it radially togetherwith a boat.
CONSTITUTION: A rudder 5 of a dredging device 4 is extended forward and a casinf 6 is sunk keeping a proper slope. A boat 1 is revolved radially centering around alternately either of two driven-in piles located at a stern, and the boat 1 is moved forward as it dredges a certain area where the casing 6 passes. Dredging is performed by driving a cutter situated on a side facing in the radially-advancing direction of the casing 6. The inside of the rudder 5 and the inside of a draining hopper 7 on board are constructed in a sealing system, and compressed air is fed. And thus,a dredged place on a side facing in the advancing direction of the dredger is kept in a caison condition, and no water enter in. As a result dredge sludge is fed to the draining hopper 7 in such a condition as includes no water.
