Abstract: A process is used for the renovation or new construction of corrugated sheet metal tunnels. The corrugated sheets are sandblasted for cleaning and room cleaning. Then anchoring elements are welded to the rough side of the sheets. A layer of shotcrete is applied to this roughened side of the sheets to obtain a smooth coating over the crests and valleys of the sheets. A reinforcement net is placed on this layer and a second layer of shotcrete or mortar is applied to cover the reinforcement net. The top layer can be smoothed. The subsequent corrugated sheet metal tunnel includes corrugated sheets covering the tunnel walls and ceilings with the course direction of their wave crests and valleys parallel to the circumferential direction of the tunnel profile. The corrugated sheets on the inside and/or outside of the tunnel are reinforced with an applied reinforced concrete layer.
