Vibration-free and Safe cutting of Pier Head on VIP Road and Airport Entry Road Crossing
Works of new projects like Noapara- Bimanbander Metro Extension Project have been going on even during the lockdown. one of the most tough works on this alignment has been dismantling of four most critical redundant piers situated in the middle of the crowded VIP Road and Airport Entry Road under which Metro Railway tunnel is being constructed. It has been decided to dismantle these piers by vibration-free diamond wire sawing . one of the piers (No: P-81 having diameter of 1.5 metre) has been dismantled recently with diamond studded cutter belt in only 7 hours without making any dust or noise pollution. Dismantled portions of this pier have been unloaded quickly by two 70 T and 35 T cranes with all safety precautions at the intersection of the two very busy roads of Kolkata.
It is to be noted that there are 104 spans along the old abandoned Circular Railway which are to be dismantled along the proposed new Metro Railway underground alignment between the Jessore Road and Biman Bander Station in order to make it infringement free.
