Description

At the dam Keban and its hydroelectric power plant, Ekinciler constructed 4 ventilation ducts, each sized to 2.0 x 2.0 m, and steel ventilation flues on the walls to prevent the cavitation damage caused by water sluiced from the splash end and the cavitation damage arising on the sluice discharge canal after having crushed the existing radial foundation and walls on the filled sluice, using liquefied carbon dioxide, for the first time in Turkey, with remote controlled hydraulic cutters. Again to prevent the cavitation damage caused by water sluiced from the splash end of the filled sluice, it made a sill structure of massive, reinforced concrete built on driven piles with a diameter of 2,000 mm with a total length of 3,081 meters in a passive anchorage system where small piles with a diameter of 200 mm with a total length of 7,400 meters were affixed on the limestone. During these operations, concrete was cast using a method called tremie, with imperviousness ensured though the construction of a 10,900 m² injection curtain.
