Added On December 8, 2019

Two large shield tunneling machines have rolled off the production line in Zhengzhou, capital of central China's Henan Province. They are to be exported to France for the construction of Paris Metro Line 16.
Let's have a look.
With 9.86 meters in diameter and an overall 115 meters in length, the two shield tunnel boring machines were produced by the China Railway Engineering Equipment Group Co., Ltd headquartered in Zhengzhou.
The two machines will tunnel through layers of plaster, clay, marl and limestone along the Paris Metro Line 16.
The metro line is a major part of the Grand Paris Express rapid-transit metro network and expected to be put into operation in 2023.
Chairman of CREG says the project makes the company the first-ever and only Chinese shield tunneling machine manufacturer to help build the Paris Metro.
CREG has been an industry leader in China since 2012, and topped the world in 2017 and 2018 in terms of shield tunneling machine production and sales volume.
The company has exported its products to 20 countries and regions including Italy, Denmark, Singapore, Australia and Algeria.
