Can be done. As a heavy machine tool, for example, a hole drilling machine is used, so that drilling to an appropriate height of a slope and driving of an anchor bolt can be easily performed.

  In the inventions of claim 2 and claim 3, a work table for construction of the side wall that is continuous with the side of the slope is provided on the end of the work deck, so that the slope side Construction of the high position of the side wall which continues to the position is performed.

  In the second and third aspects of the invention, the work deck is provided with an auxiliary work deck that can project to the slope side, and the safety fence of the auxiliary work deck can be disposed close to a position along the slope. Therefore, the construction work close to the slope is safely performed.

  According to the present invention, it becomes possible to easily carry out reinforcement work or the like at an appropriate height position on the slope without fixing the work deck, thereby shortening the construction period and reducing the number of workers. A significant cost reduction is possible.
