On August 2, the shield tunneling machine successfully completed its second tunneling, and the second tunnel of jiangpu Road tunnel new construction project was successfully completed.

Recently, a grand opening ceremony for the Yangtze River shield crossing project was held at the construction site of the East China-Russia Natural gas pipeline project (Yonker - Shanghai).

On July 15, with the successful completion of the last rail welding joint of The National Library Station, the project of the middle section of Beijing Metro Line 16 (Xiyuan Station - Ganjiakou Station) achieved the goal of connecting the long rail as scheduled, laying a solid foundation for the early operation by the end of 2020.

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.

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.
