The Art of Tunnel Rehabilitation with Shotcrete
The art of rehabilitation of tunnels has flourished and developed significantly over the last couple of decades. Several hundred railroad, highway, and conveyance tunnels have been successfully rehabilitated, converted, and/or enlarged. Much of this development can be attributed to the successful use of steel fiber-reinforced shotcrete. The flexibility and adaptable nature of steel-fiber microsilica shotcrete is ideal for rehabilitation of tunnels. Thanks to shotcrete, enlargement and rehabilitation of tunnels without fully taking the tunnel out of service is not only technically but also economically feasible consid-ering the cost of other alternatives including the œdo nothing alternative. Enlargement was usually accomplished by raising the crown but some have been enlarged by lowering the invert, which is much more difficult and time-consuming.
Tieton Dam Spillway Rehabilitation
Johnson Western Gunite Company rose to the challenge of rehabilitating the Tieton Dam Spillway in Yakima, WA. The spillway, built originally in 1924, was showing significant deter-ioration due to freezing and thawing, weathering, and erosion due to high-velocity water flow. The owner, the United States Department of the Interior Bureau of Reclamation, designed a repair consisting of a 12-in.-thick (300 mm) reinforced, cast-in-place concrete overlay on the floor and left wall if one was looking downstream. The budget in the original contract was not sufficient to overlay the right wall.
Shotcrete Repair in Paper Mill
March 2002, and May 2002. Work was conducted inside process vessels in a pulp mill by the specialized lining contractor, Canadians Stebbins Engineering Ltd., and the shotcrete contractor, Béton Projeté M.A.H. Due to operational constraints and significant costs involved with downtime, the contractors™ primary goal was to perform a repair that would provide long-term reliability within the shortest construction period possible.
