Abstract:

To provide a method for arranging a corrosion proof sheet for a tunnel, which dispenses with a large-scale apparatus.

There is provided a method for arranging a corrosion proof sheet on the internal peripheral surface of a tunnel. First, the cylindrical corrosion proofing sheet 20 is attached to a cage 24 such that the corrosion proofing sheet maintains a predetermined interval from the internal peripheral surface 23 of the tunnel 22. Thereafter, the corrosion proofing sheet 20 and the cage 24 are conveyed into the tunnel 22 at a portion to be protected from corrosion, and the corrosion proofing sheet 20 is temporarily supported by a spacer 28 such that the corrosion proofing sheet 20 maintains the predetermined interval.
