PROBLEM TO BE SOLVED: To provide a system for continuously conveying concrete, which continuously supplies the concrete in large quantities to a desired placing area in a dam from supply equipment for the concrete by making a concrete supply path ascend while following an increase in height of a dam body in the process of dam construction. SOLUTION: This system is equipped with a continuous concrete mixing plant 10 which is installed on a shore in a field of the dam construction, a plurality of conveyor devices 22, 24, 26 and 28 which convey the concrete to the placing area from the plant 10, posts 38, 40 and 42 which are erected in the field of the dam construction and support the conveyor devices 22, 24, 26 and 28 so that height positions of the conveyor devices 22, 24, 26 and 28 can be changed upward while following the height of the dam body 12, tower type cranes 46 and 48 which are formed ascendably/descendably and can support the conveyor devices 22, 24, 26 and 28 so that the height positions of the conveyor devices 22, 24, 26 and 28 can be changed, and a mixing box 44 which allows the concrete to be continuously mixed for conveyance.
