Tw Rcc Dams Display

  1. 1. Various applications of international RCC dam construction By: Ted Warren USA
  2. 2. Al Wehdah RCC dam Jordan/Syria • Medium paste RCC 60C/60A
  3. 3. 103 Al Wehdah RCC dam nearing completion of RCC • 6th fastest RCC dam constructed worldwide when completed
  4. 4. Conveyor layout Al Wehdah RCC Dam Jordan/Syria
  5. 5. Al Wehdah under construction 2005-2006
  6. 6. • Simple installation process • Less capital costs = Alliance asset and can be sold for various uses in the mining and quarrying industry
  7. 7. C1 Conveyor Configuration C2 C3 C4 C5
  8. 8. Conveyor sections removed as the dam rises C1 C2 Swinger
  9. 9. RCC delivery system • 350 m overland conveyor with integrated stepped sectional conveyor tranfers with swinger discharge conveyor for loading haul trucks on the fill • Simple system used worldwide successfully for RCC dam construction • This system was used on 8 of the top 10 fasted constructed RCC dams in the world (MDA database) with placement rates ranging from 52,000 m3 per month to 125,000 m3 per month • Al Wehdah Dam was the 6th fastest RCC Dam constructed with an average monthly rate of 75,000 m3/ month of the 360 RCC dams completed world wide. (MDA database) • Access walkways for safety, continuous maintenance ,and inspection purposes without an interruption to the RCC operation while in production • Simply mechanical system = Less down time • Wider conveyor = less speed = less segregation and less maintenance • Less up front Capital = better value for money
  10. 10. Al Wehdah complete
  11. 11. 155 m tal Ralco RCC dam Chile
  12. 12. All conveyor RCC delivery system
  13. 13. 155 m Ralco Dam Chile RCC placement 24 hrs 5 th fastest RCC dam constructed worldwide when completed
  14. 14. • I.6 million m3 RCC • Main conveyor with transfer to feed link conveyor combined with a tripper conveyor and Crawler Placer system on the fill • Trucks were loaded on the fill directly from main conveyor when the complex system used for placement on the dam was being installed and during down time. • This system is very effective for large and extremely complicated RCC dams generally over 1 million m3. •
  15. 15. Ralco nearing completion
  16. 16. GERCC application
  17. 17. Mc Alpine RCC/CVC Navigation lock USA
  18. 18. Yeywa Hydropower project Myanmar/Burma • 134 m tall • 2.34 million m3 RCC • 790 MW hydropower scheme • Non Gated OGEE spillway • Converging spillway chute with “ski jump” and plunge pool discharge
  19. 19. Yeywa RCC Dam Myanmar ?Burma
  20. 20. Yeywa dam nearing completion • Powerhouse under construction • Headrace penstocks for powerhouse intake
  21. 21. Dong Nai 4 Vietnam • 130 m tall • Hydropower project • 1.3 million m3 RCC
  22. 22. Dong Nai 4 RCC startup
  23. 23. Don Nai 3 Vietnam • 103 m tall • 1.01 million m3 RCC
  24. 24. Prepared by: Ted Warren RCC consultant USA partial listing of RCC projects • Contact information: damted2000@yahoo.com • Phone: USA + 001 210 845 7648 • International consulting worldwide • 20 years RCC dam construction experience in 8 countries on 5 continents • International research and feasibility studies • Estimating services
