Chennai: The Chennai Metro Rail Limited (CMRL) will be carrying out inspection the of 21km elevated corridor. The test will be conducted to understand the structural strength of the work. This is to check the stability of elevated metro corridors that constructed across two arterial roads.
CMRL will soon carry on ut inspection drive of the constructed structures. To carry out the inspection work, Chennai Metro officials are trying to identify firms with expertise. The selected firm will investigate, inspect and prepare a report and offer suggestions if any.
CMRL operates a 21km elevated corridor beginning from Thirumangalam ramp to St Thomas Mount and the other from Saidapet ramp to Airport.
An official from CMRL shares that it is imperative to carry inspection of elevated corridors. This becomes necessary when the elevated segment completes two years of function.
The selected contractor will only carry out an inspection of the corridor and give in a report to CMRL in six months time. Based on the report necessary steps will be taken.
The inspection of the structures will be carried on set parameters. These include stability, strength and development of cracks among the few others.
During the inspection, more than 500 columns and the viaducts above them will be investigated throughout the assessment.
As per CMRL official, the most significant aspect of the structure is the rubber bush. This is found between the columns as well as the decks on where tracks are laid. There is a need to periodically check the position and conditions. Disturbances also have to be spotted, which occur due to movement of trains above.
These inspections are very critical to ensure the safety of metro commuters as well as those using the road below the structure.
Just recently a piece of concrete from a pillar fell on an auto rickshaw in Kochi. The pillar was located on the elevated corridor. Thankfully, passengers escaped unhurt.
As per Chennai metro officials, this time the entire corridor is getting inspected.
