The tunnelling between the ZIL and Krymskaya stations under construction of the future Troitskaya line of the Moscow Metro is more than 30% complete, according to Mr. Andrey Bochkarev, Deputy Mayor of Moscow for Urban Planning and Construction.
The Mosinzhproekt Group of Companies is a general designer and general contractor for the construction of new lines and stations of the Moscow Metro.
“The ‘Alexandra’ and ‘Sofia’ tunnel boring machines (TBMs), which connect the future ZIL and Krymskaya stations, have covered about 600 metres of the planned route each,” said Mr. Andrey Bochkarev.
According to Deputy Mayor, this is more than 30% of the total length of the about 1.8 km long underground route.
“Currently, both TBMs have passed under the Marka Shagala Embankment section which is currently under construction and are working under the bed of the Moscow River”, specified Mr. Andrey Bochkarev.
Mr. Yuri Kravtsov, CEO, Mosinzhproekt JSC, added that at the neighbouring Krymskaya station, where ‘Sofia’ and ‘Alexandra’ were due to arrive, the planning of the construction site and the installation of secant piles were ongoing.
“The enclosing structures of the Krymskaya station complex pit are almost a quarter complete”, commented Mr. Yuri Kravtsov on the work progress.
The head of the engineering holding informed that the construction of the running tunnel between the Krymskaya and the Akademicheskaya stations, which was about 2.2 km long, continued on the Troitskaya line’s central section, where the ‘Natalia’ and ‘Svetlana’ TBMs were in operation.
“All other stations of the line under construction from the Akademicheskaya to the Bachurinskaya stations, located in Kommunarka, are already connected by tunnels, with the rigid base and track superstructure being installed”, explained Mr. Yuri Kravtsov.
Recall that there are nine stations of the two sections under construction being in the area of responsibility of the Mosinzhproekt GC, located on the Troitskaya line, being constructed stage by stage: ZIL, Krymskaya, Akademicheskaya, Vavilovskaya, Novatorskaya, Universitet Druzhby Narodov, Generala Tyuleneva, Tyutchevskaya and Mamyri.
The 40 km long Troitskaya metro line will connect the platforms of the Moscow Central Circle (MCC) with the urban district of Troitsk, passing through Southern, South-Western, Troitsky and Novomoskovsky districts of the capital. The expected daily passenger traffic flow is about 100 thousand people per day. About 1 million people live near the new stations, and several hundred thousand more work or study nearby.
