(Italian State Railways) Our first experience with the shotcrete method dates back to 1958. We constructed a pressure water pipe tunnel which was part of the Monastero Hydroelectric Tunnel; the client was the Italian State Railways. The section of the tunnel constructed by us was 7000 m long, plus three access-adits (1000 m long). The main tunnel (7000 m long) had a circular shape, and an internal diameter of 7 m; the cross section was 54 m2. The area where the work was carried out is named "Linea del Tonale" (Tonale line) and it is characterized by very bad geological conditions.
