TUNNELLING BETWEEN THE FUTURE MAMYRI AND BACHURINSKAYA STATIONS OF THE TROITSKAYA LINE IS ALMOST HALFWAY DONE

The tunneling is planned to be completed by the end of the year

“The tunnels that will connect the Mamyri and Bachurinskaya stations of the Troitskaya Line built on the territory of New Moscow are almost halfway through”, 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 running tunnel with two single-track tunnels between the Mamyri and Bachurinskaya station complexes of the future Troitskaya Line is 47% complete. The tunneling is planned to be completed by the end of the year,” said Andrey Bochkarev.

He specified that the right running tunnel is erected by the “Evgeniya” tunnel boring machine which has passed 1254 meters, and the left tunnel – by the “Daria” TBM which has left behind 1114 meters out of more than 2.5 km between the station complexes.

“Currently, active work is going on at the stations of the first 13-kilometer stage of the Troitskaya line from Novatorskaya to Bachurinskaya; the general construction readiness of which is estimated at 41%,” explained the Deputy Mayor.

In his turn, Yuri Kravtsov, General Director of Mosinzhproekt JSC, said that the Ulitsa Generala Tyuleneva and Mamyri stations are ready for more than a quarter; in-situ concreting are conducted including the construction of concourses. The readiness of the future Novatorskaya and Tyutchevskaya stations is above 40%. The architectural and finishing work are continuing in the service rooms.

“Universitet Druzhby Narodov is at the highest degree of readiness out of five station complexes where the excavation backfill and installation of utility systems is already underway. Its readiness is about 57%,” said the holding head.

Troitskaya metro line which is about 40 km long will connect the urban district of Troitsk, Troitsky and Novomoskovsky Administrative District with stations of the Moscow Central Circle. It is assumed that its daily passenger traffic will be about 100,000 people per day, with about 1 million people living near the new stations, and a few hundred thousand more people work or study in this area.
