摘要

The apparatus has a towed part (1) in a cylindrical form and a smoother part (2), where the two parts are articulated with respect to each other. The smoother part has an underside adapted to a profile of anticipated reparation, and two cameras to visualize and record the works. The height of the smother part is adjusted with respect to the towed part for adjusting the thickness of a material to be installed.
