Mizuiku Global Summit 2024 convenes in Việt Nam for first time
1.
HÀ NỘI — After two months of transportation and installation, the last component of a tunnel boring machine (TBM) was scheduled to be placed at the S9 underground station of Metro Line No 3, Nhổn - Hanoi Train Station, yesterday.
This TBM, the first of its kind to be used in Hà Nội, was designed specifically for the construction of the Nhổn - Hanoi Train Station metro line. Made by German manufacturer Herrenknecht, it is more than 100m long and weighs about 850 tonnes.
It is able to bore about 10m of tunnel each day in ideal conditions, according to the Hanoi Metropolitan Railway Management Board (MRD). Another TBM is being transported to Việt Nam.
After installation is finished, the machines will begin boring from the S9 station on Kim Mã Street to the S12 station at the Hanoi Train Station, located at the end of Trần Hưng Đạo street, with the total length of 4km.

Tunnel segments will be installed upon the boring progress.
MRB deputy head Lê Trung Hiếu said that local houses will not be affected during the boring process as the TBMs include earth pressure balance shields that minimise impact on geological features.
The MRB is working to make sure the progress is on schedule as requested by the Prime Minister so that the remaining 4.5km-long underground section will become operational in late 2022, he added.
It reported that a little over 67 per cent of the pilot metro line has been completed, with 82 percent of the elevated section done.
In October, the first train, designed and produced in France, arrived at the Nhổn depot. Its four carriages have been installed and being examined to prepare for trial operation.
Metro Line No 3 is scheduled to have its 8.5km-long elevated section, from Nhổn to the S8 station at the University of Transport and Communications, put into commercial operation in late 2021. The remaining 4km-long underground section will run in late 2022.
The project costs 1.176 million EUR (more than US$1.4 million) in total, including official development assistance loans from the French Government, the French Development Agency (AFD), the Asian Development Bank (ADB), and the European Investment Bank (EIB). — VNS
