World record record will be broken
For the tunnel in Bilecik Karaköy location, which is the longest tunnel of the line, which is 26,6 kilometers, a special device called 'Tunnel Boring Machine' (TBM) was produced from Germany. The giant mole weighing 2 thousand tons is one of the largest tunnel boring machines in the world. TBM Site Chief Sertaç Tokcan stated that 20 meters of excavation will be done daily with the machine. Currently, the world record in the tunnels is 380 meters per month. Sertac Tokcan states that they will break the world record by reaching 540 meters per month. As the excavation is carried out, the interior of the tunnel will be covered with specially prepared concrete blocks. CPC will start digging from tomorrow. 135 people will work in double shifts. The tunnel is planned to be completed in 14 months.
