STM

The Steel Tunnel Method (STM) is a construction method to install a bit smaller horseshoe-shaped steel tunnel into the old tunnel and build a tunnel welded and unified with the old one. This method achieves the improvement of water distribution functions or strength in obsolete water tunnels with no need in new land purchase or in the demolition of existing facilities.
