Tunnel machine punches 10 meters in Lightning White days

Tunneling machine Yildirim Beyazid drills 10 meters per day: Excavation works under the sea floor are carried out by a machine designed to be designed for this project, which is called Yıldırım Bayezid and opened by Prime Minister Recep Tayyip Erdoğan. Yildirim Bayezid, which was produced in Germany, was installed in the 40 meter depth area, which was opened specially in Haydarpaşa site. The 110 bar was designed to withstand the pressure of the bee, as the Bosporus would be exposed to approximately 11 meters of water pressure as it passed through the ground beneath the seabed. Again, while designing the machine, it is equipped with pressure cells that allow both pressure-balanced cells and divers to operate for possible interventions and change of cutting teeth at various periods.
Second in the world
Yıldırım Bayezid 11 in the world with the operating pressure of 2 bar between the tunneling machines. In the world, 13.7 6 in the world with meter digging diameter. ranks. While the length of the machine is the 120 meter, the total weight is about 3 thousand 400 tons and the heaviest part that is connected at one time is the cutting head with 450 tone. Tunnel Boring Machine, which started excavations in Haydarpasa on the Anatolian side, will proceed by digging the soil under the 25 meter of the sea floor and forming the inner walls. Yildirim Bayezid excavates between 8-10 meters per day.
