A second scraper 35 is also provided between the vibrating plate 53 and the stirring screw 33. The second scraper 35 is used to make the stirred concrete in a preliminary horizontal state. After the concrete is leveled by the vibrating plate 53, the air bubbles inside are emptied, but there will still be uneven small air bubbles remaining on its surface. The rupture of the air bubbles will damage the flatness and fineness of its surface. Therefore, a horizontal scraper 54 is provided after the vibrating plate 53 levels the concrete. The horizontal scraper 54 is used to remove the air bubbles remaining on the surface of the concrete and make the concrete floor in a state where the surface is smooth and horizontal.
