PURPOSE:To improve the efficiency of rubble-mound levelling, by a method wherein a conveyor, which can run on a barge, travels together with a truck with a hopper, and feeds rubble-mound, fed from a rubble-mound feeder, to a hopper supported to the truck, is located below the rubble-mound feeder. CONSTITUTION:After rubble-mound is dropped through a rubble-mound feed hopper 11, the rubble-mound conveyed by means of a feed conveyor 12 and is dropped onto a running conveyor 13. The rubble-mound is then conveyed by means of the running conveyor 13, and is conveyed in a hopper 3 of a trunk 2 connected to the conveyor 13 by means of a bin 18. This eliminates the need to change the position of the rubble-mound feed hopper 11 for the supply of the rubble-mound or move the truck 3 with the hopper to the hopper 11, resulting in the possibility to pefrom an efficient rubble-mound work. |
