Final Breakthrough in Suez Canal Road Tunnels

0

Egypt’s President H.E. Abdel Fattah al-Sisi and Dr.-Ing. E.h. Martin Herrenknecht, Chairman of the Board of Management of Herrenknecht AG, were personally present at the final TBM breakthrough of the Mixshield S-960 at Ismailia.

Egyptian President Abdel Fattah al-Sisi recently inaugurated very significant development projects at the Suez Canal. These included two gigantic twin-tube road tunnels under the international trading artery. A total of four tunnel tubes were driven in about 1.5 years for the new, efficient transport links under the artificial waterway. The shells are now almost completed: two road tunnels were built north of Ismailia and run under the old and new Suez Canal. Two more cross beneath the canal south of Port Said. With this key large-scale project, Egypt is expanding infrastructure immensely important for world trade. The efficient connection of the canal cities to the waterway’s eastern shore will simplify trade activities, facilitate traffic and support economic development of the region.

On Dec. 23, 2017, the third Herrenknecht Mixshield S-960, with a diameter of 13.02 m, completed the final drive for the road tunnel project at Ismailia on the Suez Canal. For the new Suez crossings, President Abdel Fattah al-Sisi ordered a total of four identical state-of-the-art tunnel boring machines (TBMs, S-958 – S-961) from Herrenknecht. Under the direction of the construction companies joint ventures Arab Contractors/Orascom and Petrojet/Concord/CMC, in the past 19 months these giant tunneling machines safely produced the tunnels near the Egyptian cities of Ismailia and Port Said at depths of up to 60 m and at a water pressure of up to 6 bar. All in all, the high-tech machines from Schwanau bored and built 15.3 km of new tunnel during this time.

A total of four tunnel boring machines were supplied by Herrenknecht for construction of the two new road tunnels under the Suez Canal. The Mixshields with a diameter of 13.02 m created over 15 km of new tunnel for the large-scale project.

To allow for a smooth project progress during the very complex tunnel operations, Herrenknecht AG trained 40 Egyptian engineers in Schwanau and on the jobsites. For optimal support of the tunneling processes, Herrenknecht also provided the tunneling teams with comprehensive services and supplied key peripheral equipment through the Herrenknecht subsidiaries VMT, MSD, Formwork, H+E and TMS.

Egypt’s President Abdel Fattah al-Sisi and Dr.-Ing. E.h. Martin Herrenknecht, Chairman of the Board of Management of Herrenknecht AG, were personally present at the final TBM breakthrough of the Mixshield S-960 at Ismailia. President al- Sisi emphasized that the project was crucial to Egypt’s future. The previously neglected economy of Sinai Peninsula can grow as a result. The tunnels will shorten the time for crossing the Suez Canal immensely: currently this can take up to five days, as queues of traffic to the ferry back up for miles. With the new tunnel connections, soon it will take only 10 minutes.
