Moscow starts tunneling for Rublyovo-Arkhangelskaya Metro line
The tunnel-boring complex (TBC) 'Lilya', which is excavating the section of the Rublevo-Arkhangelskaya Line between the 'Serebryany Bor' and 'Strogino' stations, began moving under the Big Strogino embankment.
Consensus
- A tunnel is being constructed between 'Serebryany Bor' and 'Strogino' stations on the Rublyovo-Arkhangelskaya Line of Moscow Metro.
- The tunneling is being carried out by a large shield machine named 'Lily'.
- The work is taking place under the Big Stroginsky Reservoir.
- The tunneling is occurring at a depth of at least 23 meters from the bottom of the water body.
- The geological conditions are complex, with alternating layers of sand, clay, gravel, and limestone.
- The project is being conducted under strict quality control by Moscow's construction oversight bodies.
- The shield machine began operations in January.
- The tunnel will be part of a broader metro expansion program in Moscow.
