The earthworks are completed by 95%
“Completion of the Novatorskaya station at the central section of the Troitskaya metro line is estimated at more than half”, said Andrey Bochkarev, Deputy Mayor of Moscow on Urban Planning and Construction.
Mosinzhproekt Engineering Holding is a general designer and general contractor to construct the new lines and stations of the Moscow metro.
“Cast-in-situ activities are completed by nearly two-thirds, and the earthworks by 95%. Backfill is done by more than a third. Besides, the work related to construction of the railheads, which are being built employing a trenchless method, is in progress”, said Andrey Bochkarev.
The Deputy Mayor reminded that driving of the right running tunnel between the Vavilovskaya and Novatorskaya stations on the Troitskaya line has begun this month. The tunnel boring machine (TBM) “Svetlana” will need to drive more than 1000 metres of the rail road track.
Previously, the TBM “Lyudmila” began driving of the left running tunnel from Vavilovskaya to Novatorskaya, being more than 1400 metres long.
Yuri Kravtsov, General Director of Mosinzhproekt JSC, added that construction of the principal structures continues in the southern concourse of Novatorskaya.
“Cast-in-situ activities are completed in the lower trough part of the concourse, with the columns, external and internal partitions being currently built. Besides, the inclined tunnel required for installation of the escalators is being reinforced”, said Yuri Kravtsov.
The Head of Engineering Holding specified that concourse No. 1 will not only provide the entrance to the Novatorskaya station of the prospective Troitskaya line, located along Leninsky Avenue, but will also function as a transfer to the operating same-name station on the Big Circle Line (BCL) opened in December 2021 as part of the start-up section comprising 10 stations.
In addition to Novatorskaya and Vavilovskaya, the central section of the Troitskaya line comprises the Akademicheskaya and Krymskaya stations under construction, as well as the ZIL station under design.
The Troitskaya metro line, being 40 km long, will connect the platforms of the Moscow Central Circle (MCC) with the city district of Troitsk, going through the Southern, South-Western, Troitsky and Novomoskovsky districts of the capital city. The expected daily passenger traffic flow is somewhat 100 thousand people. About one million people live near the new stations, and several hundred thousand more work or study nearby.
