Recently, as the "departure" 2 whole section tunnel boring machine (TBM) cutter slowly from the receiver to break rock, which means that the central park station to the smooth realization of the left line between rock temple station tunnel breakthrough, achieved after return to work and production stages in the construction of rail transit, at the same time for the second phase of line 9 promote the next phase of track-laying and other follow-up work has laid a solid foundation.

On the morning of June 16th, the shield tunneling machine "Gongfu 2" smashed the ground and set off smoothly at the right line of Jinchu Street Station. This marks the realization of dual tunneling of Suzhou Metro Line 6, which speeds up the tunneling of shield of Line 6 again.

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. However, nowadays, with its continuous development and construction, Shanghai has already had a very good urban traffic track construction.

Recently, the right line of the port and machine section of the 01 section of zhengzhou Airport to Xuchang Municipal Railway of The Railway Construction Company lasted for 15 months and successfully completed the long distance connection of shield tunnel, marking a new breakthrough in the key nodes of the underground section project.

The Shanghai Airport Link line has 9 stations, which adopt the national railway standard, with the design speed target of 160km/h, and adopts the laying method of viaduct, ground and underground, mainly underground. The project is scheduled to be completed and put into operation in 2024, when the transit time between hongqiao and Pudong is expected to be less than 40 minutes.
