Dam Design and Construction, Reservoirs and Balancing Lakes

After 1970, the improved quality of rockfill has favored the development of a very cost effective type of medium and high dam, the Concrete Faced Rockfill Dam (C.F.R.D.), which also applies to dams well over 100 m (fig. 3). The whole dam body is in rockfill; construction is thus easier than with the traditional Earth Core Rockfill Dam.

without moving the drill bit. Improving Efficiency and Reducing Costs Induction heating generates the heat within the drill bit so it heats from the inside. Both torches and ovens heat from the outside, are not as efficient and take much longer to preheat the drill bit. Heating a drill bit to 600°C (1100°F) often will take 2 hours
