description	PROBLEM TO BE SOLVED: To promote work efficiency without damaging natural environment in the case a dam body is executed. SOLUTION: A concrete conveyor is so constituted that a tower-like rising and falling shaft 1 of a plurality of masts 2 is approached to the side wall surface Da of a dam body D and is installed in a river bed section R. The masts can be extended upward to install a crane 3 to one top of them in a liftable manner. A stage 6 capable of rising and falling and fixing is installed in the rising and falling shaft. A vertical conveyor 15 for rising and falling between the river bed section and stage is provided. A hopper 20 having concrete from the vertical conveyor and a horizontal conveyor 21 for horizontally conveying the concrete to the dam body side are provided to the stage. The crane is a self-climbing type tower crane 4. A rising and falling mechanism for raising and lowering the stage is provided. The vertical conveyor is used for a bucket raised and lowered with a winding machine 16, the winding machine is installed at the river bed section, and a sieve for winding a wire 17 is provided to the stage. The horizontal conveyor is used for a belt feeder capable of being turned to incline, and a tilt shoot is provided to the lower part of the front end of the belt feeder.
