On September 18, 2018, a Robbins slurry machine, measuring 13.7 m in diameter, made its first cut into hard rock
On September 18, 2018, a Robbins slurry machine, measuring 13.7 m in diameter, made its first cut into hard rock for the Hiroshima Expressway Line 5 project in Japan. The launch at an urban jobsite was made possible by Onsite First Time Assembly (OFTA) of the TBM. The contractor, a joint venture of Obayashi-Taisei-Kosei, had a strict timeline of eight months to adhere to when it came to machine assembly. “This deadline was very important. After assembling the TBM, I think OFTA was appropriate for this project,” said Mr. Ryota Akai, Deputy Project Manager for the Obayashi JV.
All over the world, private and freight traffic will continue to increase. According to the German Federal Statistical Office, even now more than half of all people live in cities and the surrounding areas. Globalisation and urbanisation are causing these infrastructure developments. As a result, people, raw materials and goods are being moved around more than ever before. Civil engineering is confronted with increasing demands; this includes structures for transport and utility networks. Tunnels and bridges are key elements. Such projects are normally tendered internationally. For business reasons, the bidding companies must be able to use reliable and exactly definable construction machines or formwork and scaffolding systems.
After about 9 km each through tough gneiss, on September 11, 2018 the tunnel boring machines “Queen Eufemia” and “Queen Ellisiv” achieved a double breakthrough near the city center of Oslo. The Follo Line Project is currently Norway‘s largest infrastructure project and involves the construction of the country‘s longest railway tunnel. The two 20 km long tunnels connect Oslo with Ski further to the south. From 2021 they will shorten travel time for commuters by half.
