The Eurasia Tunnel

The Eurasia Tunnel is heading down to the sea today: the Eurasian Tunnel Project, which the Prime Minister called 'Marmaray'a brother', was first seen. 10'in completed the project, the submarine work has been reached.

The Eurasia Tunnel, which is the most important connection of the project that will connect the Asian and European continents to the highway tunnel under the sea floor for the first time, was first displayed under the ground. The Bosphorus Highway Tunnel (Eurasia Tunnel), which will reduce Kazimçeşme and Göztepe between 15 minutes, continues at full speed. 5.4 10 420 XNUMX with tunnels will be found in the XNUMX'un completed, while the Eurasian Tunnel XNUMX meters reached a length.

2017 will finally open
Tunnel boring machine Yildirim Bayezid will take the excavation work to a new level by entering the ground under the sea for the first time. The Tunnel Boring Machine, produced in Germany specifically for the 1.3 billion dollar project, will pass under the 106 meter of the sea level at the deepest point. Bayezid will not approach the sea floor more than 26 meters. The project is expected to be paid in 7 annually.

Refuge rooms are being built
The Eurasia Tunnel was designed with all disaster scenarios in mind. In an earthquake-resistant tunnel built against the earthquake and tsunami, there will be a refuge in every 200 meter in case of an accident and an explosion. These rooms feature leakproof doors. Passengers entering the rooms in case of danger will not be affected by gas and smoke, emergency evacuation ladders will allow transition to upper and lower sections. Both sides of the tunnel will have ventilation chimneys and a central operation building on one side.

Mobile opening for fault
In order to prevent the vehicles failing in the tunnel, there will be a mobile in every 600 meter. With the 7 / 24 closed circuit camera and event detection systems, the tunnel will be monitored quickly and the passengers in the tunnel will be able to intervene quickly. All surfaces in the Eurasia Tunnel, where modern lighting technology is used, will consist of non-fire-resistant materials. As with other tunnels, radio frequencies will be informed by the drivers. The difference of this frequency feature from other tunnels will be to inform the vehicles in the lower and upper sections from different frequencies. For example, a traffic accident in the lower section will be announced from radio frequencies, while passengers in the upper section will not know about this situation and will not be panic.

Kazlıçeşme-Göztepe 15 minutes
With the completion of the Eurasia Tunnel, the travel time between Kazlıçeşme and Göztepe, which normally takes 100 minutes, will go down to 15 minutes. In the project which will connect the continents of Europe and Asia under the Bosphorus by the road, the 5.4 two-storey tunnel under the sea floor will be 3.34 km long. The total distance between Kazlıçeşme and Göztepe is 14.6. For the tunnel, road expansion and operations, vehicle underpasses and pedestrian overpasses will be built on the total 9.2 kilometer in Europe and Asia.
Light vehicles only
The Eurasia Tunnel, which aims to reduce the traffic density in Istanbul, is being constructed as two floors, one of which is arrival. From the tunnel designed for the passage of only light vehicles, cars and vans can pass through heavy vehicles, motorcycles and pedestrians. Tunnel tolls will be 4 USD + VAT for cars, 6 USD + VAT for vans. In both directions, the transition is indicated as a toll, while automatic toll systems such as motorways are planned for wages. The tunnel will only be for the vehicles and there will be no additional payment for the passengers.

26 will run the year
Make Buildings from Turkey and Eurasia Tunnel Center as a joint venture of SK E & C companies from South Korea-Operate-Transfer will be implemented in the project. Eurasia Tunnel was established by the partnership of two companies, Avrasya Tunnel Management Construction and Investment Inc. (ATAŞ) for 25 years, 11 months and 9 days. During this period, ATAŞ will be responsible for the operation and maintenance of the tunnel. At the end of approximately 26 years, the tunnel will be transferred to the Ministry of Transport, Maritime Affairs and Communications, General Directorate of Infrastructure Investments (AYGM).

Punching 10 meters per day
Excavations under the sea floor are carried out by the machine, which is specially designed for this project, which is called Yıldırım Bayezid, which was 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.
