On the afternoon of May 27, the Hanoi Urban Railway Management Board (MRB) informed about the phenomenon of mud and soil mixture spraying onto the ground during the tunnel drilling process with TBM No. 1 at the underground section of the Hanoi Urban Railway Pilot Project, Nhon - Hanoi Station section.

Accordingly, in the afternoon of the same day, during the digging process with TBM No. 1, a mud mixture was sprayed onto the ground in front of houses 25C and 25E Cat Linh, Cat Linh ward.

Mud and tunneling additives erupt on Cat Linh street

As soon as the discovery was made, the contractor immediately activated the project's emergency procedure, and relevant units stopped drilling by TBM No. 1 to reduce the amount of mud sprayed up while still ensuring the stability of the excavation face.

Authorities used sandbags to cordon off the area of ​​mud and soil that erupted on Cat Linh Street.

The contractor has taken remedial measures, mobilized maximum manpower, sludge suction trucks, collected and treated sludge at the site, and re-examined geological conditions in the area where the phenomenon occurred to stabilize the situation soon. Currently, MRB is closely coordinating with relevant units to accurately assess the cause and deploy technical measures to prevent similar incidents in the next phase.
