Inside Unloading Conveyor Tunnel
The tunnel is constructed using a method similar to the dome construction. A 215-foot long Airform is inflated in a trench then workers go inside, apply 1.5 inches of polyurethane foam, attach steel, and spray layers of shotcrete. The finished wall is 14 inches thick with dual-layers of reinforcing steel rebar.
