PRESS RELEASE

 

CONSTRUCTION WORK OF THE D -WALL OF LAUNCHING SHAFT BEGINS

 

Kolkata, Date: 02.07.2024

Construction work of Purple Line beyond Majerhat station has got a major boost in recent time. The Purple Line of Kolkata Metro which stretches from Joka to Esplanade is now operational from Joka to Majerhat. Efforts have been made to extend it further as per the plan and reach the heart of the city to connect it with Blue Line as well as Green Line. In order to achieve this, construction work of Mominpur (Excl.) to Esplanade stretch of this Corridor has been going o­n in that direction. Work Order for construction of this stretch has already been issued to M/s. Larsen & Toubro in last July.

 

After Mominpur, this stretch will go underground and four stations namely, Khidderpore, Victoria, Park Street and Esplanade will be underground stations. All these stations will be modern state-of-the-art stations replete with all passenger amenities. Executing agency Rail Vikas Nigam Limited (RVNL) is bringing two Tunnel Boring Machines (TBM) to burrow the tunnels for this stretch from Germany. These TBMs are expected to arrive in Kolkata in January, 2025 and after assembling will begin their tunnelling work from March, 2025.

Prior to that, the preparatory work to construct the launching shaft has been going o­n.The construction of the D-Wall of this launching shaft has started from 27.06.2024 at St. Thomas School premises at Khidderpore. The length of this D-Wall will be 65 metres and this construction is expected to be over within two months. This is a major boost for this project after overcoming a lot of administrative and legal problems.

 

Apart from that, the casting work of the tunnel segments has also been started at the casting yard at Sarkarpool in Maheshtala. Width of each segment which will be used in the tunnels is 1.40 metre.For forming o­ne complete ring of inner diameter of 5.80 metre and width 1.40 metre, six such segments will be required. All these pre-cast segments will be brought to the site before the tunnelling work begins. The TBM machines immediately after boring the tunnels will fix the lining with these pre-cast segments under the ground to give it a final shape.
