NFM Technologies has just been awarded the supply contract for a 6.6m diameter EPBM, that will be used in the construction of one of the principal sections of the second circular line for the Moscow metro system.
The line is part of an ambitious programme drawn up by the Moscow authorities to increase their Metro coverage by more than 70km. It will link in with several radial lines, considerably reducing pressure on the first circular line build in the 1930s.
The TBM, built on behalf of SMU ENGEOCOM, will bore a twin-tube tunnel through geology mainly comprising limestone, clay and sand.
The tunnel will link the ‘Khodynskoe Pole’ and ‘Delovoy tsentr’ stations, to the north west of the city, some 6,200m in total, with two intermediate stations at 2km intervals.
The machine is to be manufactured by NFM’s workshops in Le Creusot, with delivery scheduled for the end of 2012.
NFM Technologies, a French designer and manufacturer of TBMs, has already provided two machines for the Russian market, specifically for the Kazan Metro.
