Milestone for hard Rock Tunnelling: Final double Breakthrough Follo Line in Norway

 

The construction of Norway's longest railway tunnel marked a breakthrough for the use of tunnel boring machines in hard rock tunnelling. In Scandinavia long rail tunnels have hitherto been drilled and blasted rather than bored. In the Follo Line Project, the tunnel boring machines made a convincing case for themselves all the way through the extremely hard Norwegian rock. Four tunnel boring machines (TBMs) by Herrenknecht worked simultaneously to excavate the main part of two 20-kilometer railway tunnels between Oslo and Ski. On February 26, 2019, the final double breakthrough of the Double Shield TBMs "Anna" and "Magda" successfully completed the challenging mission and drew a spectacular close.

Neue Wege in den Sinai – finaler Durchbruch bei gigantischen Straßentunneln am Suez-Kanal

Am Weihnachtswochenende läutete der ägyptische Präsident S.E. Abdel Fattah al-Sisi eine neue Epoche für die Sinai-Halbinsel ein: Der dritte von vier Herrenknecht-Mixschilden S-960 (Ø 13.020 mm) beendete am Samstag, dem 23. Dezember 2017 die Vortriebsarbeiten für den ersten von zwei neuen, doppelröhrigen Straßentunneln unter dem Suez-Kanal. Die Tunnelbauwerke bei Port Said und Ismailia sollen die Sinai-Halbinsel künftig stärker an das ägyptische Kernland anbinden und eröffnen neue wirtschaftliche Chancen. Anstatt bis zu 5 Tage vor der Fähre in langen Auto-Schlangen zu verbringen, wird die Passage des Suez-Kanals über die leistungsfähigen Tunnel künftig lediglich 10 Minuten dauern.

New Routes to the Sinai – final Breakthrough in gigantic Road Tunnels at the Suez Canal

On the Christmas weekend, Egyptian President H.E. Abdel Fattah al-Sisi rang in a new era for the Sinai Peninsula: on Saturday, December 23, 2017, S-960 (Ø 13,020 mm), the third of four Herrenknecht Mixshields, completed tunnelling for the first of two new twin-tube road tunnels under the Suez Canal at Ismailia.
