[0046] When the trowel plate 5 moves to the other side, the cylinder 6 is used to adjust the inclination of the trowel plate 5 again, and it is adjusted to the opposite inclination direction. At the same time, the hydraulic cylinder is used to confirm the height of the trowel plate 5 again. After it is suitable, the driving motor is started to rotate in the reverse direction, and the trowel plate 5 can be driven to move to the edge of the road surface on the initial side again;

[0047] The above process is repeated until the cement slurry in the working area is smoothed to the required height, and then the counterweight support 11 is moved to the next working area until the smoothing operation of the cement slurry in the entire area is completed.
