Paris Metro Line, the automatic super metro network in the suburb of Paris planned by the French government, has long been known for its high standard and high-end positioning. The 9.8m-diameter TBMs from CREG will be used on Paris Metro Line 16.2 to drive a 11.2km tunnel with the maximum overburden of 8 to 52m and the maximum water pressure of 5bar. The tunnel features geology comprised of limestone, marl, gravel, etc. and will pass through densely populated areas, buildings and stations. Confronted with complex geological conditions and strict construction requirements, CREG elevates the stability and adaptability of the machines via meticulous design and responds our Italian contractor with customized solution and superior service, becoming the first Chinese TBM supplier for Paris Metro Line.
