The excavation of the left stage tunnel from the new Teatralnaya station to the dead ends of the existing Alabinskaya station of the Samara metro has started.
The Alabinskaya - Teatralnaya stage will become one of the longest in the Samara metro 1600 meters.
“The unique experience and professional competencies of Moscow metro builders are in demand outside the capital. The excavation will be carried out in a closed manner using a Herrenknecht S-755 mechanized tunnel boring complex (TBMC), which was named “Samara”. Previously, this TBM built tunnels on the Sokolnicheskaya, Solntsevskaya and Big Circle lines of the Moscow Metro", – said the General Director of Mosmetrostroy JSCSergey Zhukov.
A tunnel-boring complex was installed in the starting pit on Galaktionovskaya Street, from where it began moving towards Alabinskaya. The TBM will pass at a depth of up to 25 meters. The penetration rate in the first two months will be 50-100 meters, in the future - 250 meters per month. According to the schedule, it is planned to complete the excavation of the left distillation tunnel at the end of this year. The exit of the shield is planned at the intersection of Samarskaya and Polevaya streets, where a dismantling chamber has been built.
Let us remind you that the metro will come to the historical center of Samara - Teatralnaya will become the 11th and final station and will complete the first line of the Samara subway.
General Director of Volgatransstroy JSCVyacheslav Sonin noted: “On the first day after Easter Sunday, we, together with specialists from Mosmetrostroy, launched the Samara tunnel boring shield. I am confident that, taking into account our joint experience in constructing similar facilities and with God’s help, we will succeed.”
