Tunnel shafts are vertical passages that connect the ground surface to the tunnel roof. When the position and course of the tunnel are correctly aligned and accordingly set out on the surface, shafts are sunk at defined points on the tunnel line to aid tunneling operations. Shafts have many advantages and are used in constructing […]
