21m above ground, Phase III line goes over Blue Line
The Delhi Metro Rail Corporation (DMRC) for the first time in Delhi Metro’s history has constructed an elevated track segment over another operational elevated segment, at a record height of 21 metres above the ground.
Anuj Dayal, chief spokesperson (DMRC), said this is for the first of its kind crossover at Karkarduma, and he also mentioned that similar constructions will also come up at Netaji Subhash Place, Dhaula Kuan, Mayur Vihar and Anand Vihar.
The new line is division of the Majlis Park-Shiv Vihar corridor of Phase-III, which runs over the Vaishali-Dwarka line at Karkarduma. As per DMRC the overlapping sections cross each other at an angle of 114 degrees and are vertically 10 metres apart.
Dayal added the length of the new section between the piers on either side is 37 metres. He further added constructing it was not a simple task; due we tried not to affect the operations on the Vaishali-Dwarka line even for a day. Construction was done after operations stopped on the Blue Line each night and no trains were authorized to run when work above was in progress.
As per DMRC official , via CCTVs, round-the-clock monitoring of the process was done to avoid eventualities such as electrocution or material falling on the existing line, along with pre-stressing beam, monitoring of earthling provided to the launching girder, erected segments or any other loose items kept on the span.
Dayal alleged a similar elevated viaduct crossing an existing elevated viaduct will be constructed as part of Phase-III At four more locations, which is slated to be completed by 2016. The Majlis Park-Shiv Vihar corridor will pass over the Red Line at Netaji Subhash Place, Blue Line at Mayur Vihar and Anand Vihar, and the Airport Line at Dhaula Kuan.
