PROBLEM TO BE SOLVED: To provide a device capable of automatically placing, leveling, and compacting concrete. SOLUTION: A hopper 21 for holding concrete is provided at the rear of a vehicle 1. A screw conveyor device 3 is disposed at the lower part of the discharge port of the hopper 21. A screed base 22 having a vibrator or a tamper device 23 is provided at the rear of the screw conveyor device 3. The vehicle 1 is moved forward, and the screw conveyor device 3 and the vibrator or tamper device 23 are driven to continuously input concrete into the hopper 21. The screw conveyor device 3 places and uniforms concrete by spreading in the direction orthogonal to the advancing direction, and the concrete is compacted by the vibrating screed base. As a result, the concrete is deposited in band shape. By continuously inputting concrete in the hopper 21, a concrete depositing placed, spread, and compacted automatically can be performed.
