Accelerate the progress! New progress in the construction of airport connecting lines
The shield tunnel of Section 13 has started, and the "Three Centers" project has completed the corridor elevation. The construction of airport connecting lines has made new progress in multiple aspects recently.
On the construction site of the 13th section of the urban railway airport connecting line, which was invested and constructed by Shanghai Shentie and undertaken by Shanghai Construction Engineering, with the successful completion of the 9-meter air cushion mud water balance shield tunneling machine "Jianshun", the section from Pudong Airport Station to the planned T3 terminal of the 13th section has officially entered the shield tunneling construction phase.
The 13th section of the project is located in Zhuqiao Town, Pudong New Area, with a total length of approximately 5.7 kilometers, including the Pudong Airport working shaft, south turn ramp bridge pier replacement, section tunnel and related ancillary works. Among them, the section from Pudong Airport Station to the planned T3 Terminal Station has a left and right double track length of about 3.03 kilometers, with two connecting passages. The construction of the section is carried out using two 9-meter mud water pressure balancing shield tunneling machines. Among them, "Jianshun" is responsible for the double track excavation between Pudong Airport Station and Pudong Airport Working Well, as well as the right track excavation between Pudong Airport Working Well and the planned T3 Terminal Station.
The working shaft of Pudong Airport is an underground three story shield tunneling starting shaft, with a narrow construction site and frequent cross operations. The project team innovated construction ideas, solved the problem of limited lifting of shield tunneling machines, and ensured the safe starting of shield tunneling machines.

The Shanghai Municipal Railway Dispatching, Operation, and Skills Training Base project, which was invested and constructed by Shanghai Shentie, designed by China Railway Shanghai Institute, and constructed by Shanghai Construction Fourth Construction Group, has successfully completed the lifting and hanging work of the "Three Centers" project corridor after five months of upper structure installation and one month of corridor ground assembly. This marks the crucial conclusion stage of the main structure construction of this "super brain" of the municipal railway.
At present, the basement and above ground floors of the "Three Centers" project have passed the municipal high-quality structural evaluation in batches and entered the decoration and installation stage. After the completion of the project, it will play an important role in improving the networked operation, dispatch management, and employee skills training of the Shanghai urban railway.
