After that, “Victoria” will continue tunneling to the future station “Stakhanovskaya”. There are 706 meters left before the entrance to its pit, which corresponds to the 392-m rings of concrete lining.
After entering the pit, the technological operation “excavation” of TBM, a complex of repair and restoration works to prepare tpmk for further sinking, relocation and installation of technological equipment, as well as relocation and installation of temporary buildings and structures will be performed.
Then the sinking will continue on the next section – between the future stations “Stakhanovskaya” and”Nizhegorodskaya”. The length of the alembic tunnel will be 1,394 meters.
