In the Narlıdere Metro, where the Izmir Metropolitan Municipality has laid the foundation, the 7.2 kilometer-long line will be overcome by digging the 2 meter per day with the 20 tunneling machine called ğ TBM ğ. Installation 40 100 day-long vehicles and the deep tunnel technique to be applied, the city traffic and daily life, subway construction will be affected at the minimum level.
Izmir's 180 km rail system network continues to grow. Izmir Metropolitan Municipality, 14 is adding a new ring to rail system investments that have been continuing for years. The construction of the F. Altay-Narlıdere line, whose foundation was laid in June and that the tender price was 1 billion 27 million TL, is still under construction. . Deep tunnel ”will be passed by using 7.2 kilometer line, 2 pieces CPC (tunneling machine). Thanks to TBMs, the possible traffic, social life and infrastructure problems during tunnel construction will be minimized. In the sector, with the machines described as yap underground monster mak, an excavation of 20 meters in Narlıdere Tunnel will be carried out. At the end of the 42 month planned construction process, Narlıdere metro line, Balçova, Çağdaş, Dokuz Eylül University Hospital, Faculty of Fine Arts (GSF), Narlıdere, Siteler and Kaymakamlık including 7 stations.
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 CPCs to be used in the construction of İzmir Metropolitan Municipality Narlıdere Metro has been brought to the field and the installation preparation has been started. The other machine will be brought to the city after a while reported.
