KANPUR (Metro Rail News): Under the Kanpur Metro Rail Project, the construction work of underground section-I (Chunniganj-Nayaganj) of the first corridor (IIT-Naubasta) is progressing at a brisk pace. Today on 26th March the work of preparing the diaphragm wall (D-wall) for the construction of Chunniganj Underground Metro Station of this section has been commenced. At the other three stations of the said section namely Naveen Market, Bada Chauraha and Phoolbagh-Nayaganj, D-wall construction is ongoing and at Naveen Market and Bada Chauraha, this work is expected to be completed by the end of April month.
The work of D-Wall was first started at Naveen Market Metro Station. 102 D-wall panels have to be lowered in this station, out of which 87 have already been placed. At the same time, 84 out of 100 D-wall panels have been placed at Bada Chauraha Metro Station and 68 out of 107 at Nayaganj Metro Station.
What is D-Wall?
A D-wall can be understood as the boundary of an underground metro station. Before starting the construction of an underground metro station, this wall is constructed as a security enclosure around it. The D-Wall is formed with rectangular RCC panels. The length of the panels for D-wall in Kanpur’s Underground Section-I, will be around 5 meters and the width will be around 800 mm and approx 100 such panels will be used to form the D-Wall around each station. This wall will exist up to a depth of about 21 meters.
