Uttar Pradesh Metro Rail Corporation Limited (UPMRC) has commenced the ‘Utility Identification and Diversion’ process on the underground Metro Corridor to be built between Chunniganj and Nayaganj as Underground Section-I. The process includes identification of telecom-electric cables and water-sewer pipelines under the ground and their shifting-diversion as needed.
Usually, these utilities are identified through manual excavation but here in Kanpur, UPMRC is using the state-of-the-art technology of Ground Penetrating Radar (GPR) to identify utilities (telecom-electric cables and water-sewer pipelines). Through GPR technique, underground utilities are identified using Radio Waves. Radio Waves are sent below the ground and they identify the obstacles beneath. Through the frequency received at the receiver, it is decoded that, which type of obstacle is there. In Kanpur, UPMRC is using 200-400 MHz frequencies to identify them precisely even at greater depths.
Managing Director, UPMRC, Kumar Keshav said, “Usually, utilities like cables and pipelines are located up to two meters depth below the ground, but Kanpur is an old planned city, so there is a possibility of finding these utilities even at greater depth. UPMRC wants to ensure that the tunnelling work in the future won’t get affected due to these utilities and people won’t have any inconvenience. GPR ensures it can locate and image the utilities, up to 10 meters depth below the ground”.
The start of Utility identification and diversion process is part of second leg of phase one of Kanpur Metro project between Chunniganj and Nayaganj. In between these two ends, there will be four metro stations – all of them would be underground.
Since the stations would be underground, metro authorities is now engaged in identifying utilities (telecom-electric cables and water-sewer pipelines) and shifting/diverting them, if needed.
