Reference

The BCL will connect existing and prospective radial lines at a distance of up to 10 km from the existing circle line (Koltsevaya). Thus, Moscow metro passengers will no longer have to go to the city center to transfer from one radial line to another, change to a neighboring line, and then return back.

Effect

Radial metro lines will be unloaded by up to 30%

Saving up to 30 minutes on each trip

The metro will come to Nizhegorodsky, Mozhaysky, Khoroshyovo-Mnyovniki, and Ochakovo-Matveyevskoye districts

Technologies

How metro tunnels are constructed?

Back in the 1930s, the first Moscow metro stations were built with a pickaxe and a shovel. Today the arsenal of metro builders includes tunnel-boring machines. They come in two types: ‘tens’ (10-meter diameter) and ‘sixes’ (6-meter diameter).

The machine with a 6-meter diameter constructs single-track tunnels; there are two of them. The 10-meter machine is for double-track tunnels where trains of different directions go towards each other on parallel tracks.

BCLs are laid in conditions of dense urban development. To eliminate the negative impact of noise on houses near the stations, vibration protection technologies are used.

  • The rotor is a rock-cutting mechanism
  • The jacks are pushing off the mounted ring and move the machine forward
  • Tubing is an element of ferroconcrete ring that strengthens the tunnel
  • The block-layer assembles the tunnel ring from tubes
  • The ventilation duct supplies air from the ground surface
  • Conveyor is used for waste soil removal

Concrete deep and low-depth stations

Most of the Moscow metro stations operating since 1935 are concrete deep. It took from 3 to 5 years to build them. Since 2011, there have appeared more low-depth stations, the depth of which does not exceed 30 meters. It takes about 2.5 years to construct one.

Concrete deep stations appear in places with a large number of engineering communications, the removal of which requires large financial expenses and time. There are three such stations on the BСL: Savyolovskaya, Rizhskaya, and Maryina Roscha.

What are double-track tunnels for?

The Moscow metro mainly has single-track tunnels. There are double-track tunnels only on some metro lines. Such tunnels were constructed at the dawn of the Russian capital's metro development and mainly with the use of manual labor.

Today double-track tunnels are constructed with one giant 10-meter machine. The main advantages of such tunnels are safety, low noise level, speed, and reduced construction costs.

The tunneling of all circle was completed in in 2021.

MAN OF LABOR

20,000 people do not stop the construction of the BCL even for a minute. While you are reading this, the metro has already become a little longer.

CONSTRUCTION PROCESS

FUN FACTS

TRUE OR FALSE

1 9

Is it true that ...

The longest escalators of Moscow metro will be at the Maryina Roscha station of the BCL?

CORRECT:

Maryina Roscha station will have the longest escalators in the Moscow metro. The length of each is 130 meters –724 steps. Passengers will descend to the depth of 64,5 meters. The escalator at the Park Pobedy station with a length of almost 127 meters is now considered to be the leader in the capital.

Is it true that ...

A giant tunnel boring machine with a diameter of 10 meters was delivered to Moscow from China?

CORRECT:

Pobeda was manufactured in China in accordance to the technical task of engineers of Mosinzhproekt JSC. The journey to Moscow City took 50 days. The ship's path to St. Petersburg was by the Northern Sea Route: The Pacific Ocean – The Bering Strait – The Arctic Ocean – The Barents Sea – The North Sea – The Baltic Sea. Then the oversized cargo was delivered by river to the Southern Port of the capital, while the large one – by road transport. Firstly, machine constructed a tunnel from the Klenoviy Bulvar station in the direction to Kashirskaya.

Is it true that ...

A fish museum will appear at one of the BCL metro stations?

CORRECT:

Nagatinskiy Zaton station is being constructed on the "island" of the district of the same name. There is water and tunnels "diving" under the river nearby. The most complex construction, which required careful research of the river bottom. 12 species of fish inhabit the place. That is why water design of the station won. Images of fish will decorate the walls, while the ticket hall will become a kind of museum.

Is it true that ...

One of the BCL stations will be five-leveled?

CORRECT:

Due to the tight urban development, the BCL station Michurinskiy Prospekt is being built in cramped conditions. It will become a five-leveled one.

Is it true that ...

Kuntsevskaya station of the BCL is being built by an open method at a depth of 50 meters?

CORRECT:

The depth of the foundation pit is 33,6 meters. When it was excavated, the enclosing structure diaphragm wall became the deepest in Moscow – 45 meters. Usually its maximum is 30-35 meters.

Is it true that ...

Usually it takes several days between the ending of the construction and opening of the station?

CORRECT:

It normally takes several months between the completion of the construction and opening of the station – this is the stage of adjustment works. It is essential for running in the tracks, checking the equipment and including a new section in the metro system. Before launching passenger trains, the new section is tested by technical ones.

Is it true that ...

The design of the tunnel boring machine was inspired by worms?

CORRECT:

According to a legend, the Englishman Marc Brunel came up with the design of the first machine after he took a closer look at the "work" of the ship worm. He noticed that the head of the mollusk was covered with a hard shell with jagged edges. With its help the worm drilled into the tree, leaving a smooth protective layer of lime on the walls of the passage. The idea turned into design in 1817, and in 1825 due to the first model of the machine, construction of tunnel under The River Thames in England began.

Is it true that ...

Moscow construction workers were the first ones in the world to lay inclined tunnels for escalator zones with the help of tunnel boring machines?

CORRECT:

A special complex was developed in Canada by order of Mosmetrostroy JSC. With its help, for the first time, a shield tunnel for escalators was made – at Maryina Roscha station of Lyublinsko-Dmitrovskaya metro line.

Is it true that ...

The BCL will become the "second ring" of the subway?

CORRECT:

The first one is Koltsevaya line, the second one – Moscow Central Circle (considered a surface metro) and the third one is BCL.
