PUNE (Metro Rail News): In January, the officials are planning to start the second Metro tunnel work in January after inspecting the progress of the first one. The parts of the second tunnel boring machine (TBM) have arrived at the Metro site at Agriculture College.
Maharashtra Metro Rail Corporation Limited (MahaMetro) said, the assembling is underway and will take a few days more. After trials, the actual work of digging would begin.
Both TBMs will work from the Agriculture College-end towards the civil court. The first machine, after the initial trials, started the digging work last week. The MahaMetro said the progress of the tunnel boring had so far been satisfactory and no technical challenges were faced in the initial run.
MahaMetro further added that according to the plan, there will be separate tunnels for Up and Down lines. They will run parallel on the entire stretch from the Agriculture College to Swargate. The alignment of tunnels and underground Metro stations have been finalized. Four TBMs would be involved in the tunneling work. A similar shaft is coming up at the Swargate-end to insert two more TBMs.
A senior official from MahaMetro said “We have expedited the shaft work at Swargate. It will be handed over for further stages soon,”.
The MahaMetro officials stressed that the project work was progressing according to the schedule. The manufacturing of casting rings to be inserted in the tunnel has been expedited. Over a thousand rings are ready at the casting plant. The officials stated that the tunneling work was complicated and involved a lot of technical monitoring.
“We are keeping an eye on all necessary parameters,” one among them said. The MahaMetro has also started the underground Metro stations’ work. The first stations in the underground Metro stretch from the Agriculture College-end are Shivajinagar and Civil Court. The initial work of the entry-exit points of both the stations has started.
