The in-situ concreting at the site is almost 80% complete
“The underground interchange from the Elektrozavodskaya station of the Big Circle Line (BCL) to the same name metro station of the Arbatsko-Pokrovskaya line is nearly two-thirds complete”, 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 interchange is 61% complete,” said Andrey Bochkarev.
According to him, the in-situ concreting at the site is almost 80% complete.
“Also, the waterproofing is over 85% complete, three-quarters of backfilling works have been completed, tunnel mining is nearly 50% complete,” noted the head of Moscow Complex of Urban Planning Policy and Construction.
Yuri Kravtsov, General Director of Mosinzhproekt JSC, explained that tunnelling is carried out in difficult hydrogeological conditions.
“Cementing practice is used to reduce water inflow during construction. The interchange is being built under the existing Big Circle tunnel and over the current Arbatsko-Pokrovskaya line tunnel without suspending train service. There is a round-the-clock monitoring of operating and new structures under construction of the Moscow Metro”, specified Yuri Kravtsov.
The Elektrozavodskaya BCL station is part of the northeastern section of the Big Circle. It temporarily operates as part of the Nekrasovskaya line together with the Aviamotornaya and Lefortovo stations.
Based on the Elektrozavodskaya station, a major transport interchange hub (TIH) is being created, which, in addition to the Big Circle Line and the Arbatsko-Pokrovskaya line stations and the Elektrozavodskaya platform of the Moscow Railway, to become part of MCD-3 in future, will include a pedestrian overpass that will connect Semyonovskaya and Rubtsovskaya Embankments. Now all three superstructures of the bridge are already assembled.
