About-turn for „SUSE“ in the Filder Tunnel

 

In late July the moment has come: tunnel boring machine "SUSE" (Ø 10,820 mm) has completely excavated the western tube of the Filder Tunnel. Now, in a specially built cavern, the approximately 120 meter long Multi-mode TBM from Herrenknecht is disassembled into individual parts and turned around underground. From the fall of 2018 it is due to commence excavation work in the remaining 3.4 kilometer section of the eastern tube.

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. The tunnels at Port Said and Ismailia, designed to link the Sinai Peninsula more closely to the Egyptian heartland in future, will open up new economic opportunities. Instead of spending up to 5 days in long car queues for the ferry, crossing the Suez Canal via the efficient tunnels will only take 10 minutes in future.
