Conical Manhole

K K Manhole and Gratings Company Pvt Ltd offers Conical Manhole. Traditionally in India, manholes for providing access to telecommunication and sewer lines have been made from bricks. However, brick manholes are time consuming to build and are not structurally strong. Recognizing these problems, KK developed and introduced the conical manhole assembly system. The conical manhole assembly system has now being overwhelmingly accepted by the telecom majors and is the predominant system used to provide access to underground telecom cables. The conical manhole assembly system consists of conical rings (each of height 225 mm) made from precast reinforced concrete that can be stacked one on top of the other to construct a conical shaped manhole. In addition, a precast concrete frame and cover are also provided at the top. This system allows the flexibility to customize the height of the manhole to suit the application. Based on the number of rings used, the height of the manhole can vary from 0.5 meters (3 rings) to 1.9 meters (15 rings). In telecom applications, conical manholes of height of 0.5 meter, 1 meter, 1.225 meter, and 1.45 meters are primarily used.
