The Delhi Metro Rail Corporation on Sunday reopened Aurobindo Marg for traffic after successfully repairing the 60-year-old storm water barrel below. The road, between IIT and AIIMS, was closed on June 2 following leakages at some points in the storm water barrel.
According to officials the leakage occurred due to backflow of the rainwater, which let to settlement near the Metro construction site.
In the absence of layout plans for the barrel, the DMRC engineers began the repair after excavating the area for proper investigation to avoid surface settlement. The road had to be excavated 5 meters below the surface to reach the brick barrel, which had seven leakages. The DMRC also had to consider the different gas pipelines, waterline, CNG line and MTNL cables passing through the area. The repair work was inspected by DMRC managing director E. Sreedharan, who also gave technical input to the engineers working there.
