A fleet of four Dynapac single drum vibratory rollers is currently working on the massive Alkumru Dam in south east Turkey as part of a major hydrolectric power plant project.
A total of 18M.m3 of clay and rockfill is being compacted to form a finished structure with a height of 134m from foundation level and a crest length of 909m.
The $500M (£314M) project, which employs a workforce of 1,250 people, is being undertaken by Limak HES Yatirimlari.
The Alkumru Dam is one of seven dams to be constructed on Botan Brook, a tributary of the River Dicle. Once completed, at the end of 2010, the dams will create a series of large lakes for the hydroelectric scheme.
Three of the rollers on the project are Dynapac’s CA512D smooth drum machines, used for compacting layers of rockfill, while the other is a CA512PD padfoot version, which is working on the cohesive clay areas. All fourmachines have a drum width of 2.13m. Each machine makes three or four passes of up to 200m in length to achieve the required 99% compaction.
