摘要:PROBLEM TO BE SOLVED: To provide a scaffold for an open-cut method allowing a worker to easily conduct the work at the middle position of both retaining panels and to move over a ditch. SOLUTION: This scaffold is suspended over a ditch 2 excavated between two retaining panels 1 driven on the ground surface. The scaffold is provided with a first gangway board 20 which has a first tread board 21 arranged above the ditch 2 from one retaining panel 1, a hook board 22 fixed to one end section in the longitudinal direction of the first tread board 21 astride the upper end of one retaining panel 1, and tubular sections 25 opened inward at both side face sections, and a second gangway board 30 which has a second tread board 31 arranged above the ditch 2 from the other retaining panel 1 and overlapped on the first tread board 21 at the tip, a hook board 32 fixed to one end section in the longitudinal direction of the second tread board 21 astride the upper end of the other retaining panel 1, and slide sections 34 slid in the tubular sections 25 of the first tread board 21 at both side face sections and is moved along the upper face or the lower face of the first gangway board 21.
