A What happened
The Delhi Metro Rail Corporation (DMRC) has successfully completed a complex tunneling project beneath the operational Red Line at Pulbangash as part of its Phase IV expansion. This new tunnel connects the Janakpuri West to RK Ashram Marg and was constructed without disrupting train services. The operation was particularly sensitive due to the Red Line's structure, which sits on open foundations. To ensure safety, DMRC implemented a detailed ground-strengthening plan, including the TAM grouting technique and the creation of 180 boreholes filled with high-strength cement grout. Real-time monitoring instruments were deployed to track ground movement and the condition of nearby buildings. The completion of the downline tunnel is a significant achievement, as the Red Line serves nearly seven lakh passengers daily, making any disruption potentially inconvenient.
