Picture Stories

Installation of four tunnel-boring machines that are to be used for driving the tunnels of the Kozhukhovskaya Moscow subway line in the Nekrasovka – Kossino-Ukhtomskaya – Saltykovskaya Street section is close to completion.

The Herrenknecht EPB-6150 Tunnel-Boring Machine, which has been already assembled, will be used to drive the tunnel between the Kossino-Ukhtomskaya and Nekrasovka stations (moving in the direction away from Moscow center). Assembly of the Lovat RME-242SE Tunnel-Boring Machine, which will be used to drive the right interstation tunnel, is close to completion.

The Robbins EPB-2015-371 Tunnel-Boring Machine will be used to drive the right interstation tunnel and the Herrenknecht EPB-6340 Tunnel-Boring Machine will drive the left tunnel between the Kossino-Ukhtomskaya and Saltykovskaya Street stations, moving toward the center of Moscow. These tunnel-boring machines will be completely assembled shortly.

Assembly of the first one of the four tunnel-boring machines started in February 2014.

All the tunnel-boring machines were used previously for driving six interstation tunnels, extending the Tagansko-Krasnopresnenskaya line from the Vykhino station to the Kotelniki station. The tunnels of a total length of more than nine kilometers were driven in less than eighteen months.
