Machine ordered for Moscow metro

摘要

A 6.6m diameter EPBM has been ordered for the construction of one of the principle sections of the second circular line for the Moscow metro system. French designer and manufacturer NFM Technologies was awarded the contract. The TBM, built on behalf of SMU Engeocom, will excavate a twin tube tunnel through geology that is mainly limestone, clay and sand. The tunnel will link the 'Khodynskoe Pole' and 'Delovoy tsentr' stations to the north west of the city, over 6.2km in total, with two intermediate stations at 2km intervals.
