Marmaray is safer than skyscrapers

Marmaray is safer than skyscrapers: Marmaray's official opening will be held tomorrow, connecting the two continents with rails. Introducing the system to journalists, Transport Minister Binali Yildirim said, “Vertical structures and skyscrapers in Kozyatagi and Bostanci are at greater risk”.
Bringing together the two sides of Istanbul under the sea, Marmaray will open tomorrow, on October 29, Republic Day.
Minister of Transport, Maritime Affairs and Communications, Binali Yıldırım, told the journalists who were touring Yenikapı - Üsküdar and those who were curious about security.
Yıldırım said that the 1 will be available as of November in the meeting of journalists yesterday. Yildirim said they had originally planned to finish the project before, but experienced a delay due to archaeological excavations.
'WE WON'T FINISH TO THE ARCHEOLOGIES IN 2023'
According to the news in the Milliyet newspaper, Yıldırım said, “We extended the job. In 2013, we could only finish. If we left it to archaeologists, we would not have finished this project even in 2023. I'm sorry. Now they're digging, sir, this is the 18th century. They dig a little more 17th, 16th, 15th century… Hold on a little bit, brother. There's no stopping point. Anyway, thanks to them, they allowed me after getting a certain idea. ”
Yıldırım also said that they are planning to complete Marmaray's integrated transportation systems at the same time, but they couldn't realize this because of the inconvenience about the contractor firm. . With the integration of other integrations, 2020 will have found the 450 mileage network including Marmaray until XNUMX gir.
'SKYSHERS ARE IN GREATER RISK'
Noting that Marmaray did not pass through the sea, Yıldırım shared the following information about the project:
. We are talking about a structure with an 2-2,5 meter covering on the bottom of the sea floor. When you land at the bottom of the sea there is no indication of Marmaray. The plaque is moving right and left when an earthquake occurs.
Marmaray will move horizontally with the moving plate. What is the risk? There may be deterioration in the joints, there may be a problem with the sealing gaskets between the segments ... There is no collapse other than this, because there is no cross movement. But vertical structures in Kozyatağı and Bostancı are at higher risk than skyscrapers. Naturally, it's safer. The main thing is that there is no problem between land and sea tunnels. ”
WHAT WILL HAPPEN IN THE EARTHQUAKE?
Marmaray Project Control Chief Zeynep Sindel Buket talked about the precautions against Marmaray related to earthquake, fire and flood risks.
Buket, who noted that all kinds of safety should be provided in the project as the 75 thousand passengers are planned to pass per hour, said:
Deprem Very serious studies have been carried out on seismic issues. The ground is important in the earthquake is solid. There is too much assertion. In all geological soundings, a region with a risk of liquefaction on the seabed was identified. This was done to improve the floor that could create a liquefaction. Special cement injection columns were made. This ground was solidified.
EARTHQUAKE RADARS WILL STOP THE TRAIN
With the cement injection pressure columns, a ground formation that was transformed into a rock hardened under these tubes was provided. As soon as we detected the earthquake movement, radars were placed to send signals to the Earthquake Institute and the main command center in Kandilli. Even if there is a train, it is aimed to return that train to the nearest station. ”
WHAT TO DO IN AN EMERGENCY CASE?
Sindel also noted that in case of emergency, walking bands were created in the tubes, da Let's say there was an emergency in a tunnel. Any emergency scenario such as fire. In this case, there are 1,5 meter wide walking bands for evacuation of the tunnel. Passengers will be able to move to other tunnels from these walkways. It is already a safe area. Or
IS THE OTTOMAN DREAM
The foundations of Marmaray were laid in 2004, completed in 9 years. So what stages did the project go through in this 9-year period?
Feasibility studies started in 1987 and its project was completed in 1998. In 1999 the financing agreement was signed between Turkey and the Japanese international cooperation agency. Important historical ruins were found in the excavations that started under the Bosphorus.
OVER THE TIME OF ARCHEOLOGICAL STUDIES
Archaeologists participated in the works, the works were taken to protect.
It was planned to end in 2009, but the period of time was increased due to the archaeological studies between Yenikapı and Sirkeci.
Landscaping has been made for Marmaray in many places both on the European and Anatolian sides.
Stations were installed, new sidewalks were installed. Thousands of people worked in the construction of the project, test drives began in August.
4 will be passed in MINUTE, 75 THOUSAND PASSENGER WILL BE TAKEN
The transit time from Marmaray to the Bosphorus will go down to 4 minutes.
7 stops between the two sides, namely Zeytinburnu - Kadıköy Between 19 minutes can be passed. 75 thousand passengers will be transported per hour.
Railway tunnel that will pass under the Bosphorus, with Gebze-Sogutlucesme Halkalı-Kazlıçeşme to connect with the suburban lines.
Marmaray will be connected to the Istanbul-Ankara High Speed ​​Train Line as well as the Istanbul subway.
TRANSFER FEE 1,95 TL
Passengers will be able to benefit from Marmaray for 1 lira and 95 cents. The project is planned to significantly reduce Istanbul traffic.
Especially the traffic load of the Bosphorus bridges will be reduced. The project that will allow the passage of motor vehicles in Marmaray will be put into service until the end of 2015.
