[0051] The pressure can be detected by the embedded pressure sensor 43, so as to detect the compactness of the building mortar on the ground, and thus the construction quality of the building mortar is controlled. When the pressure detected by the embedded pressure sensor 43 reaches the design pressure, the wheels 5 are driven to rotate by the driving mechanism 3, so as to ensure the consistency of the mortar compactness at each position on the ground.

[0052] Meanwhile, the foldable closing panel 41 is rotated to open, and is located in the same horizontal plane with the thickness control panel 422 and is synchronously moved with the moving vehicle body, so as to close the surface of the building mortar synchronously after the building mortar is smoothed and compacted by the thickness control panel 422, and the smoothing, compacting and closing of the building mortar are completed at one time.
