Metro building crash barriers

The Delhi Metro Rail Corporation (DMRC) is constructing crash barriers around some Metro track pillars that were reinforced after cracks were noticed during an inspection last year.

The inspection drive was initiated after the mishap at Zamroodpur on July 12 last year, where an under-construction metro bridge collapsed due to “design fault” in a pier killed seven people.

DMRC Chief Project Manager (CPM) H.K. Sharma told HT: “As an extra precautionary measure, crash barriers are being constructed at the 10 pillars which were reinforced. All pillars have crash barriers. But the ones on these pillars were demolished during the restrengthening.”

“The crash barrier will take the impact if a vehicle collides with the pillar. The main pillar will not be affected,”added Sharma.

A 9-inch-wide RCC border around the pillar base, 2 feet below the ground and 4 feet above the ground, will be built. “There is gap of 1 inch between the pillar and RCC structure crash barrier,” said a supervisor.

“The 10 pillars included pillar numbers 3, 8, 9, 10, 11, 12, 14 and 16 between New Ashok Nagar and Noida Sector 15 Metro track. One pillar number 89 was at GIP Atta crossing and pillar number 139 at Sector 37 crossing,” said Sharma.
