[0028] During construction, the drive motor 34 is started, and the drive motor 34 drives the stirring shaft 35 to rotate. When the concrete construction raw materials pass through the stirring tube 31 during transportation, the stirring shaft 35 drives the spiral blades 36 to rotate, while promoting the concrete construction raw materials to be transported to the right, the concrete being transported is stirred to avoid separation of the concrete. The stirring shaft 35 also drives the continuous spiral blades 38 to rotate.
