Patel constructs two dams at Ghatghar
A Business Correspondent
Patel Engineering Ltd, Mumbai, has constructed two of three dams at Ghatghar near Nashik using roller compacted concrete (RCC) technology. Work on the third dam is in progress. The dams are a part of the Ghatghar Pumped Storage Scheme of the state Irrigation Department. Located on Pravara river, near Nashik, the project involves the installation of a 2x125 mw reversible pump turbine and generator motor units in an underground powerhouse. The upper portion of this scheme is located near Ghatghar village, Ahmednagar district, and its lower portion is near Chonde village, Thane district.
The RCC technology, being implemented for the first time in India, enables speedy construction of dams. RCC also allows 60-70 per cent of cement to be replaced by fly ash, resulting in significant savings. The use of fly ash is being regarded as an innovative approach to the RCC method of construction. Fly ash not only reduces the heat of hydration, consequently decreasing the expenses on cooling infrastructure, but also helps utilise hazardous waste.
