In a major relief to the residents of Kidderpore, the tunnelling work of Purple Line from Kidderpore to Victoria started today.
In a breakthrough, the body of one of the eight trapped workers was brought out in the tunnel boring machine (TBM) at the accident site of the Srisailam Left Bank Canal (SLBC) tunnel in Nagarkurnool district of Telangana, 16 days after the roof collapsed, leaving it waterlogged and filled with slush.
In an unprecedented move, a part of the TBMs is to remain buried, below the site of the August 2019 mishap, for times immortal. Generally, when a TBM makes a breakthrough, its cutter head is brought out by cutting the wall and placing a cradle.
The manoeuvre will not result in soil subsidence and will as such not affect life or property above the ground over the distance over which the machine is proposed to be shifted or otherwise, according to the report placed before the Division Bench of Chief Justice T B N Radhakrishnan and Justice Arijit Banerjee of the court.
