PURPOSE: To dispose excavated material with good efficiency so as to accomplish excavating work without discharging dust in the periphery under a good working environment.
CONSTITUTION: A suction pump 3 is disposed on an excavator 1 such as a back hoe or the like, the rear end portion of the suction hose 4 is connected to the suction pump 3, and the leading end portion of the suction hose 4 is disposed in an excavating portion 5 of the excavator 1. The exhaust side of the suction pump 3 is formed in such a manner as to communicate with the suction side so that the clogged up of the hose 4 can be solved. A hopper 7 is connected to the exhaust side of the suction pump 3 through a discharge hose 6, so that the excavated material thrown into the hopper 7 and accumulated therein is loaded on a carrier 22 such as a dump car or the like and delivered. Further, a waste water treatment car 9 such as a vacuum car or the like is connected to the hopper 7 through an exhaust hose 8 to dispose of dust of force-feed air for force-feeding the excavated material.
