New Delhi: Delhi Metro Sunday successfully repaired a 60-year-old storm water barrel below the Aurobindo Marg in south Delhi, enabling the stretch to be reopened for traffic within a month.
“DMRC engineers had to excavate the area for proper investigation to avoid surface settlement. The road had to be excavated five meters below the surface to reach the brick barrel which was leaking as plans of the barrel were not available with any civic agency,” a Metro spokesperson said.
The inspection at the whole site around the tunnel area revealed that there were seven leakages which lead to flooding at the site and these leakages were then carefully plugged through concrete lining, he said.
With this, the corridor of the Aurobindo Marg from IIT towards AIIMS has been fully opened for traffic from today. This corridor had been earlier closed for commuters from June two following leakages at some points in the storm water barrel.
The damaged drain started leaking out rainwater and the soil above the tunnel and below it led to the settlement.
Around 250 workers and 12 engineers worked on a war footing for the restoration work which were carried in a location where there are gas lines, water lines, CNG line and MTNL cables passing through.
DMRC Managing Director E Sreedharan personally inspected the site at least six times to give technical directions to the metro engineers working there.
Five Mild-Steel (MS) pipes of 1.4 m diameter were laid at Hauz Khas Apartment compound by constructing a Chamber there to divert the direction of the brick barrel, which was crossing the tunnel.
These steel pipes were then joined with the already existing pipes to carry the water towards Gautam Nagar.
Furthermore, a triangular shaped man-hole chamber was created at the point of intersection of the south tunnel and the brick barrel to provide an interface area for proper water diversion.
