Launching TBM robot to drill the Nhon-Hanoi Metro tunnel

On the morning of July 30, at the S9-Kim Ma underground station, a giant 850-ton TBM robot started drilling the first meters of the Nhon-Hanoi Railway Station Metro project.

According to Mr. Nguyen Ba Son, Deputy Head of the Hanoi Urban Railway Management Board (MRB), the launch of the TBM robot at the bottom floor of the S9-Kim Ma station is an important milestone for the underground section of the project, demonstrating the determination and efforts of the parties involved in creating the capital's public transport system.

The tunnel boring machines will drill about 10 m/day.

The total time from the start of drilling of the first TBM to the completion of TBM No. 2 was 16 months.

After drilling is completed, the TBMs will be dismantled at station S12.

Mr. Nguyen Quoc Bao, Deputy General Director of FECON Joint Stock Company, shared that TBM technology at Metro Line 3 Hanoi is the world's leading advanced technology, suitable for the mixed soil geology in Hanoi.

The tunnel drilling process is closely monitored by international experts.

As the tunnel lining panels are drilled, the TBM will immediately assemble them.

The underground section is expected to be completed in 2027.
