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.
