Tunnel boring machine

The TBM shaft at Veikou for the new Line 4 of the Athens Metro was visited today by the Minister of Infrastructure and Transport, Christos Staikouras, along with the Deputy Minister of Infrastructure and Transport

Infrastructure and Transport Minister Christos Staikouras and his deputy, Nikos Tachiaos, visited the Katechaki and Veikou tunnel boring sites on the under-construction Line 4 of the Athens Metro on Monday and confirmed that the first section of the extension is expected to be completed by 2030.

Engineers of the AVAX-led consortium building Athens' new 13-kilometer metro line stand next to a tunnel boring machine (TBM) cutter head at the Katehaki site. Following consultations with local engineers, German tunneling company Herrenknecht supplied two approximately 100-meter long and 1,500-ton TBMs with a diameter of 9.5 meters.

The tunnel boring machine (TBM) used for the construction of metro at Piraeus caused damages to the yard of a house, about 130 meters away from Nikaia station to Maniatika.

The aim of getting Thessaloniki’s much-delayed metro up and running by 2016 is not attainable, representatives of workers who are constructing its tunnels and stations said on Tuesday.
