PURPOSE:To enable to perform a rapid dredging work, by a metod wherein lumps in deposited sludge are removed by a selector, the deposited sludge is crushed by a crusher to form fluid, and the fluid is fed to a forced feed tank unit to feed the fluid by a compressed air. CONSTITUTION:A sludge selecting and crushing unit is provided with a sludge selector 5 which selects dredged mud by the use of a lattice-shaped screen 23. A sludge crusher 6, having a horizontally-mounted rotary drum 31, and a screen conveyor 24, which conveys discharge sludge from the lower part of the selector 5 to the crusher 6, are provided in the rear of the selector 5. Sludge, crushed to form fluid, is charged in a sludge forced feed tank unit 8, and fluid sludge is conveyed from a unit, not shown, to a land through a feed sludge pipe by means of a compressed air. This causes dredged sludge to be fed as fluid in a ready mixed concrete manner into the sludge feed pipe, resulting in the possibility to smoothly convey quantities of dredged sludge to a land by means of the compressed air. |
