When a bulge appears on the construction surface, the liquid level in the water tank 11 located thereon is lower than the liquid level or liquid level difference set by the control system. When a pit appears on the construction surface, the liquid level in the water tank 11 located thereon is higher than the liquid level value set by the control system. The inspection personnel can sit on the driving vehicle body and observe the flatness of the horizontal plane. The vehicle body is driven by the driving body to drive two telescopic support frames, which move forward through rollers.
