Delhi Metro casts first pier under Phase-4 work

Monday, 27 July 2020 | Staff Reporter | NEW DELHI

The Delhi Metro Rail Corporation (DMRC) took another important step forward in its Phase-4 construction work as the first pier of this phase of metro expansion was casted on the Janakpuri West-RK Ashram Marg Metro corridor on Saturday night.

The pier was cast at Keshopur on the elevated stretch between Keshopur and Mukarba Chowk last night. A senior Delhi Metro official said this major construction milestone has been achieved despite severe shortage of manpower and other logistical challenges because of the ongoing pandemic.

“The average height of the piers on this corridor is 10 metres. However, the height of the piers will be 20 metres at Madhuban Chowk (crossing with Line 1) and 25 metres at Haiderpur Badli Mor where this line will cross line 2,” he said.

At Haiderpur Badli Mor, the rail level is going to be the highest i.e. 28 metres in the history of Delhi Metro, he said, adding that presently, the highest point is at Dhaula Kuan, where the line 7 viaduct passes at a height of 23.6 metres. The approximate distance between each pier will be about 28 metres.

Piers, in terms of civil engineering are vertical load bearing structures which act as intermediate support for adjacent ends of two spans. It forms the vertical support structures on which the elevated metro viaducts stand.

“Metro piers today dot innumerable road medians in Delhi through which elevated metro corridors run. Pier numbers are now important landmarks for addresses across the NCR,” the official said.

The 28.92 km long Janakpuri West-RK Ahsram Marg corridor is an extension of Magenta Line and will come up with 22 stations. While 21.18 kilometres of this corridor will be elevated, 7.74 kilometres will be underground. Construction work on this particular section had started in December last year.

On July 17, the work on the underground section of this corridor commenced with the beginning of D wall construction work at the Krishna Park Extension Metro station. On June 24, DMRC had started the casting work of u-girders which would be installed on the elevated section of this corridor.

Under phase four, 61.679 kilometres of new metro lines shall be constructed across three different corridors comprising 45 Metro stations. “These new sections shall provide interconnectivity among the already operational sections of the metro. Out of this, 22.35 kilometres will be underground while rest will be elevated,” he said.
