The 14m-class super-large diameter mud-water balanced shield, independently developed by Shanghai Tunnel Engineering Co., LTD, is used for the construction of Shanghai Municipal Airport's liaison line. With a total length of about 92m, the shield can meet the tunneling requirements of the minimum horizontal curve radius of 450m. The rear part is equipped with a 3-section integrated frame, which adopts the design of landing wheel, which can deal with many complicated working conditions such as deep burial depth and small turning radius.

As is known to all, Shanghai, known as the magic city, is the most prosperous international metropolis in China. Therefore, the development of Shanghai has always been closely watched by its partners in China.
