Soil testing survey of city land for Metro work started today on Saturday from Zero Mile. Work was inagurated by principal secretary Swadhin Kshatriya in the presence of Brijish Dixit, MD Nagpur Metro rail Corporation (NMRCL).
The Metro Rail in the city will run on elevated tracks 100 meter above the ground surface. Huge pillars, which will bear all the weight, will be erected to support the tracks. This will make the quality of the soil a critical matter. To determine the nature of the soil, NMRCL will undertake a soil survey of the land. The work for the same will begin on Saturday.
The Metro Rail will run 38 kilometers divided into North-South and East-West corridors. The soil survey is being done as a precautionary measure before starting the work of erecting pillars. The work has been outsourced to a Ahmedabad based company Anandjiwala in 1 crore. Nagpur has black soil four meters under the ground and does not have any difficult rock for 15-20 meters. To avoid any risks, the team will dig 150 mm deep holes on the ground on every 100 meters. The land will be tested on over 370 spots. A detailed report of the survey will be submitted in two months.
The reports will determine the design of the pillars and the strength of the foundation. The testing will begin at Khapri first since the NMRCL will start the work of the Khapri-Sitabuldi route.
