BEIJING, Feb. 12(Xinhua) -- The Moscow Metro Southwest Line project, undertaken by China Railway Construction(CRCC), has started shield construction with the first shield machine going into operation at the Slavic World Station in the southwestern Moscow recently.
This project is second metro project undertaken by CRCC in Russia. With a total length of about 6.5 kilometers, the metro line will consist of three stations and auxiliary structures. It will adopt a 6.28-meter diameter shield tunneling machine.
According to the construction plan, another three shield machines will be put into use before the end of March, which will greatly speed up the project building.
The project will cost 27 billion rubles (some 419 million U.S. dollars). It will connect downtown Moscow with a suburb, and is expected to significantly ease traffic congestion in the metropolis.
CRCC designed and produced five tunneling shields capable of withstanding the city's harsh winter and complicated geological conditions.
