The “Victoria” TBM, which is erecting it, is getting ready to pass under the bed of the Moskva River
“The tunneling between the Pechatniki and Nagatinsky Zaton stations of the Big Circle Line (BCL) of the Moscow Metro is more than halfway done”, said Andrey Bochkarev, Deputy Mayor of Moscow on Urban Planning and Construction. Mosinzhproekt Engineering Holding is the construction manager to construct new lines and stations of Moscow Metro.
“The “Victoria” ten-meter tunnel boring machine has passed 904 meters of the double-track tunnel between the Pechatniki and Nagatinsky Zaton stations which is more than half of the total length of the tunnel,” said Andrey Bochkarev.
At the same time, according to him, a double-track tunnel between Nagatinsky Zaton and Klenovy Bulvar is currently under construction in the east of the Big Circle Line of the metro, while the “Lilia” TBM which erects it, has passed over 70% of the route.
“In addition, tunneling of the single-track tunnel from the Kashirskaya station towards Klenovy Bulvar is underway,” added the Deputy Mayor.
In his turn, Yuri Kravtsov, General Director of Mosinzhproekt JSC, specified that currently the cutting tools of the “Victoria” TBM are being replaced at a specially equipped site, after which it will pass under the 500 meters wide bed of the Moskva River.
“The “Victoria” machine also passed the zone of dense urban development in the Pechatniki area. Part of the tunneling was passed directly under the Pechatniki station under the Lyublinsko-Dmitrovskaya Line and then under the collector of the Nishchenka river. Along the route, there are mixed soils (from sand to limestone), and heavily watered,” specified the head of the holding and assessed the general readiness of the Eastern section of the Big Circle Line in almost half.
“The Tekstilshchiki and Klenovy Bulvar stations are 50% complete on average, architectural and finishing work, and the utility systems installation is in progress. The Pechatniki and Nagatinsky Zaton stations are one-third done: the construction of the main structures of the stations continues,” said Yuri Kravtsov.
Today, four stations are underway in the east of the BCL: Klenovy Bulvar, Nagatinsky Zaton, Pechatniki, and Tekstilshchiki. Their commissioning will improve transport accessibility to the surrounding areas.
The Big Circle Line is the key Moscow Metro construction project, its length will be 70 km with 31 stations, 12 of which are already open to passengers. It will be the longest underground loop line in the world.
