Reinforcing bars 9 are pre-assembled on the road, and the form 8 of the mechanical driving device 5 is provided so as to cover the reinforcing bars 9. The ready-mixed concrete is conveyed to the hopper 6 by the belt conveyor 4, and is dropped from the hopper 6 to the introduction form 8B of the mechanical driving device 5. The ready-mixed concrete that has fallen into the introduction form part 8B partially spills on the leading form part 8A, but is compacted to a predetermined hardness by being vibrated in the introduction form part 8B. When the vehicle advances, the ready-mixed concrete compacted in advance by the introduction form 8B is transferred to the forming form 8C, where it is formed into a predetermined shape. Then, the surface of the molded product molded by the molding frame portion 8C is finished by the iron finishing mold frame 8D to form the concrete structure 10 having a predetermined shape.
