Installation of the enclosing structures has started at the krymskaya station on the troitskaya line

“Work on the future Krymskaya station of the prospective Troitskaya Line has moved into an active stage”, said Andrey Bochkarev, Deputy Mayor of Moscow on Urban Planning and Construction.

Mosinzhproekt Group of Companies is a general designer and general contractor to build new lines and stations of the Moscow Metro.

“At the Krymskaya station of the Troitskaya Line under construction, the installation of the enclosing structures of the excavation pit has started, the secant piles are being installed, and excavation on the site planning is underway”, said Andrey Bochkarev.

According to the Deputy Mayor, the builders have started setting up disassembling shield chambers to meet the tunnel boring machines (TBMs).

“Currently, there are four TBMs coming to Krymskaya, two of which are tunnelling from the ZIL station side, where in-situ concreting work has recently started, and two more TBMs are tunnelling from the Akademicheskaya side”, specified Andrey Bochkarev.

Yuri Kravtsov, General Director of Mosinzhproekt JSC, recalled that the Krymskaya station under construction was located between the tracks of the Moscow Central Circle and the residential area of the Donskoy District. There will be two above-ground concourses, one of which will be combined with the eastern concourse of the Krymskaya MCC platform to provide an interchange between the two types of transport.

“The relocation of utilities and installation of the enclosing structures of the excavation are almost complete at the neighbouring Akademicheskaya, where the first TBM from the Vavilovskaya side has already arrived, and over a quarter of the planned excavation work has been completed”, added Yuri Kravtsov.

The head of the holding specified that the construction of the main structures of the platform section and the concourse of Akademicheskaya would start after the completion of the adjacent tunnel from Vavilovskaya.

“The whole range of excavation and in-situ concrete work is underway at the Vavilovskaya station, the installation of the enclosing structures and the relocation of the utilities continue, and the excavation backfill is underway”, stressed Yuri Kravtsov.

Recall that there will be four stations on the central section of the Troitskaya Line: ZIL, Krymskaya, Akademicheskaya and Vavilovskaya. Its commissioning will provide additional integration of the new line into the Moscow’s transport framework, linking it with the Kaluzhsko-Rizhskaya Line and the MCC platforms.

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. About 1 million people live near the new stations, and several hundred thousand more work or study nearby.
