The Pflaurenz Tunnel, which is roughly 1 km long, is being built to provide a bypass which relieves pressure on the St. Lorenzen municipality in South Tirol. Half of the tunnel (approx. 417 m) passes through loose rock and was driven by excavators. To provide advance support, the innovative AT – Pipe Umbrella System with 139 [mm] squeezed connection developed by DSI Underground was successfully used in the loose rock sections of the Pflaurenz Tunnel to quickly and safely connect the tubes when driving the tunnel.
