Welcome to our live broadcast about İzmir Metro F. Altay Narlıdere Extension. In the Narlıdere Metro, where the Izmir Metropolitan Municipality laid the foundation, the 7.2 km long line will be overcome by digging 2 meters a day with 20 tunnel boring machines called "TBM". City traffic and daily life will be minimally affected by the construction of the subway, thanks to the giant vehicles with a length of 40 meters and the deep tunnel technique to be installed.

The rail system network of İzmir, which has reached 180 km, continues to grow. Izmir Metropolitan Municipality adds another ring to its rail system investments that it has been carrying out for 14 years without interruption. The construction work of the F. Altay-Narlıdere line, the foundation of which was laid in June and the tender price was 1 billion 27 million TL, continues. 7.2 km line will be passed through “deep tunnel” using 2 TBMs (tunneling machine). Thanks to TBMs, traffic, social life and infrastructure problems that will occur during tunnel construction will also be minimized. 20 meters of excavation work will be carried out in Narlıdere Tunnel with machines defined as "underground monster" in the sector. At the end of the construction process planned for 42 months, Narlıdere metro line will consist of 7 stations: Balçova, Çağdaş, Dokuz Eylül University Hospital, Faculty of Fine Arts (GSF), Narlıdere, Siteler and District Governorship.

INSTALLATION 40 CONTINUES DAY

Due to its ability to prevent undesirable underground movements, it is quieter, flicker-free and faster. Due to Narlıdere Metro's preference, TBM (Tunel Boring Machine) is a ve underground monster i 85 meter. The TBM, which is used in the opening of the huge tunnels, excavates the stone and soil that it excavates and separates it with the conveyor belt while placing the concrete slabs of the tunnel.

Each 15 complete 40 with a crew of 600 assemblies every 10 tonnes, each CPC in the tunnel, 100 meters per day. The 6.6 meter-long 360 meter-diameter vehicle runs as a full-surface digger, always moving forward. While doing digging with the disc cutters in front of it, it continues its operation without leaving the direction it should dig with the laser system. In the meantime, the hydraulic system in the body section of the machine supports the excavation with a system known as the ring and creates a temporary tunnel. When the cutting process continues to XNUMX, the cut material is filled into a hopper and transported out of the body by the conveyor belt. Then the tunnel is stabilized by using techniques such as rock screw and shotcrete.

One of the 2 TBMs to be used in the construction of İzmir Metropolitan Municipality Narlıdere Metro was brought to the site and preparation for installation was started. It was reported that the other machine would be brought to the city after a while.
