(Pics) D-Wall Construction Underway for Kolkata Metro’s Esplanade Stn

Here’s a picture-post on the ongoing diaphragm wall (D-wall) construction work taking place for the new underground Esplanade Station on Kolkata Metro’s 16.34 km Line-2.

Designed by RITES, the new station is being built underneath the Esplanade Tram Depot’s land, and in its first stage connect up with the existing Line-1’s Esplanade Station to allow easy transfers. In the future, an additional underground station box will be constructed here to serve as the northern terminal of the 15.75 km Joka – Esplanade line (Line-3), making it the city’s first 3-line interchange, and depending on its completion timeframe, perhaps India’s second after Delhi’s Kashmere Gate Station which just got connected with a 3rd line in May.

Ground work for its construction by ITD-ITD Cem JV was inaugurated in June 2017 by the then Railway Minister Suresh Prabhu. First a guide-wall was built around the site, which is now being followed by excavation, slurry cleaning, desanding, reinforcement cage lowering and finally the pouring of concrete – one panel at a time.

Here’s my go-to video to demonstrate how D-walls are built –

Once the diaphragm walls are ready and soil excavation is carried out in Q1 2018, the station shaft will become structurally ready to receive Afcons Infrastructure’s TBMs S-639 (Rachna) and S-640 (Prerna) on the west-side from Mahakaran Station, as well as allow ITD Cem’s TBMs S-615 and S-616 to be lowered and commissioned on the east-side for building the roughly 2.20 km Esplanade – Sealdah twin tunnels.

      Construction is underway on the Joka – Mominpore section only. As Rupraj highlighted above, RVNL has not yet invited tenders for the Mominpore – Esplanade section’s construction.

      Without that, Line-3 will function independently whenever it gets launched in the next 2-3 years.
