The "lightning-fast" robot digging the Hanoi metro tunnel makes the world admire

The TBM robot, worth more than 262 billion VND, has drilled nearly 2km of the Nhon - Hanoi Railway Station metro tunnel, possessing leading technology, designed specifically for the geology of the capital.

TBM robot No. 1, nicknamed “lightning speed”, has just completed a nearly 2,100m drilling section from S9 Kim Ma station to S11 Van Mieu station. (Photo: Doanh nghiep va Tiep thi)

This device is over 100m long, weighs 850 tons, is made in Germany and costs from 10-15 million USD (over 262 billion VND). (Photo: Fecon)

TBM No. 1 uses Earth Pressure Balancing (EPB) technology, helping to drill through Hanoi 's complex geology while maintaining the excavation face's stability. (Photo: Fecon)

Each time it digs, the robot simultaneously installs the tunnel lining rings, with 6 pieces completed in just 30-35 minutes. (Photo: Fecon)

Engineers call it a “modern giant”, possessing the world’s most advanced sensor system, robotic arms and sealed pressure chamber. (Photo: Fecon)

Along with TBM No. 2 - nicknamed "bold", the two robots are specially designed to handle weak ground, underground water and high population density in Hanoi. (Photo: Fecon)

Putting TBM into construction is a big step forward for Vietnam's urban infrastructure construction industry, taking the initiative from assembly to operation for the first time. (Photo: Fecon)

The Nhon - Hanoi Railway Station metro line is 12.5km long, of which the 4km underground section will be completed in 16 months with the help of these two robots. (Photo: Fecon)
