Pressure Water Tunnel for pumped-storage Power Plant in Kärnten/A

With a deafening noise and enormous force the giant tunnel boring machine thrusts its cutterhead through the rock of the Austrian Alps. Water is due to flow through the new pressure tunnel in a short time where now there is solid rock. Vibrations and dirt are still omnipresent.
