Shanghai： Self-developed super-large diameter shield machine completes the ＂first show＂

On March 2nd, Shanghai Tunnel Youth Commando workers waved flags on the "Qiyue" to celebrate the successful reception of the shield project.

On the same day, the connecting line of Shanghai regional railway airport "Meifu Road Working Well-Huajing Station" was the first to run through, marking the successful completion of the "Qiyue" and "First Show" of the super-large diameter shield machine independently developed and manufactured by Shanghai Tunnel.

According to reports, the total length of the "Qiyue" is about 99 meters, of which the length of the main engine is about 16 meters, and the cutting diameter of the cutter head is 14.05 meters. In October 2020, the commissioning was completed. During the construction period, "Qiyue" successively passed through the high-voltage iron tower, the viaduct of Hongmei South Road and the subway line 15, ensuring the safety of various complicated water, gas, electricity and communication pipelines, and finally successfully completed the underwater reception in the receiving well of Huajing Station.
