As shown in, a plurality of pairs of mooring fittings 4 are installed on the abutments 1 on both sides. Next, a plurality of main wires 3 are laid horizontally in parallel between the mooring fittings 4 of the abutments 1 on both sides. The main wire-3 is installed by, for example, equipping the temporary wire-2 installed above with the movable pulley 6 in which the tow line 5 is connected,
One end side of the main wire-3 is attached to the movable pulley 6, and the other end side of the main wire-3 is connected to one mooring fitting 4. Then, one of the tow lines 5 is pulled to move the movable pulley 6, and the main wire-3 is installed between the abutments 1. Main wire-3
After the completion of the erection, the temporary wire-2, the tow cable 5, and the movable pulley 6 are removed.

Further, a clamp 73 with a roller is attached to the pipe 71, and this roller is attached on the main wire-3 so that the scaffold 7 can be slid. Furthermore, a safety net 74 for preventing a fall is stretched on the scaffold 7. It should be noted that a drop-out preventing means is provided so that the scaffold 7 does not drop off the main wire-3.
