THE TUNNELLING BETWEEN THE VAVILOVSKAYA AND NOVATORSKAYA STATIONS IS 70% COMPLETE

“The tunneling of the line between the Vavilovskaya and Novatorskaya stations of the Troitskaya metro line is underway. Over two-thirds of the tunnelling has been completed”, said Andrey Bochkarev, Deputy Mayor of Moscow on Urban Planning and Construction.

Mosinzhproekt Engineering Holding is a general designer and general contractor to construct new lines and stations of the Moscow metro.

“The ‘Lyudmila’ and ‘Svetlana’ tunnel boring machines have tunnelled about a kilometer of the left running tunnel and over 715 metres of the right one, respectively”, said the Deputy Mayor.

According to him, it is 70% of the planned amount of tunneling of the underground track which is over one kilometre long.

“The ‘Marina’ and ‘Olga’ TBMs are tunneling in the opposite direction from the Vavilovskaya station, towards the Akademicheskaya station that is under construction. They have covered about half of the running line which is about 2.5 km long”, added the head of the Moscow Complex of Urban Planning Policy and Construction.

Yuri Kravtsov, General Director of Mosinzhproekt JSC, said that the ‘Marina’ shield, which is excavating the left running tunnel to Akademicheskaya, has covered over 1200 metres, and the ‘Olga’ machine, which is working in the neighboring tunnel, has progressed more than 1.1 km.

“Work is underway in the preparatory phase of construction on the prospective platforms ZIL and Krymskaya: utilities network relocation, construction of temporary bypass roads and construction sites”, specified Yuri Kravtsov.

The head of engineering holding added that excavation and excavation pit bracing are being implemented on Akademicheskaya, cast in-situ structures of the platform are being erected on Vavilovskaya – general construction readiness of both stations exceeds 10%.

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