What is the date for the first stop?
“The first stop will be Üsküdar. According to the normal business plan, the construction from Üsküdar to Sancaktepe is planned to be completed in 38 months. However, on the business plan, the relevant units of the Municipality are working, alternatives for opening the metro step by step are evaluated.
Is the location of the stops clear?
"Detected. Detailed studies are being carried out at the moment. Şu
How many meters deep?
Or If the diameter of the tunnel made with TBM, the Tunnel Boring Machine machine, is 6 meter, it is one and a half times the thickness of the 9 meter depth. The surface can be passed under the 9 meter. Buildings can be adversely affected and cracking may occur if you go up too much. If it goes down too much, the stations have to be made deep and the cost is rising. In general, the line goes linear, if there is no problem in the infrastructure. The Üsküdar-Sancaktepe subway will have a maximum of 32 meters below the current geology. Ü
Will there be links with the Kadıkoy-Kartal metro?
"Kadıköy-Kartal Metro merges with Marmaray at İbrahimağa Station. Üsküdar will be the first station of both Marmaray and Sancaktepe metro lines, thus the Üsküdar transfer line. In the future, Ümraniye's new financial center will be Kadıköy- There is a connection to the Kartal subway and Sancaktepe to Sabiha Gökçen Airport via Sultanbeyli, our Metropolitan Mayor announced plans for these at our groundbreaking ceremony. ”
Are there any dates for these projects?
“There is a program made by the Municipality. Kartal subway opens in August. Line; It will be extended to Pendik and merged with Sabiha Gökçen Airport. Also, Istanbul Metropolitan Municipality wants to realize projects with the build-operate-transfer model. KabataşThere is a big line called Beşiktaş-Mahmutbey. We follow from the press that studies and feasibility studies have been carried out in this project and will be put out to tender this year. ”
Will there be a subway connection between the third airport and Çekmeköy?
“The third bridge will have two floors and the train will pass through the lower floor of the bridge. This rail system can be connected to Çekmeköy. There will be a rail system that reaches the airport from there. ”
The center will be Üsküdar. Will the infrastructure remove this density?
Acak There will be a transfer station. Üsküdar develops through studies and can be a more active place. Traffic may increase slightly, but the goal is to promote public transport. The value of buildings increases; this will actually be the case for every place on the metro line. bu
Will you use a special technique on your fourth metro?
“We use the latest technology in all the subways we make. We use the TBM machine, which we call 'mole'. The device is like a computer center. There is a head that performs drilling at the front and the back is like a factory. Sometimes it goes up to 100 meters. As he advances, he pulls back. It takes the concrete segment parts that were previously prepared and that will form the walls of the tunnel, and as it progresses, it also forms the tunnel by placing them in rings, that is, circular. It then fills the gaps between this wall and the excavated ground by injection. When the machine is finished, the tunnel is physically finished. In the systems we call electromechanical, ventilation, signalization, rails and other equipment are placed later and tests are made with the arrival of wagons. We currently have 7 TBM machines that we use in various projects. ”
There was a long-term power outage in the Taksim subway and many people were stranded. Could this be a new application to avoid duplication?
Or Metros have a back-up energy system. No one should be scared, not even the power outage on the subway. Maybe there was another problem in the case you were talking about. The same is true for Marmaray. Aynı
How many people will be employed for this project?
“Since the machine is dense in tunneling works, there are fewer personnel, but there are 16 stations, each station means 8-10 floors. 2000 people will work when all stations come into play.
