Totally around 3 500 000 m3 of sand material is needed for the project. In order to find the suitable quarry, it became evident that within the radius of 40 km around the dam location, no river quarry exists. Therefore three areas were considered for this purpose.
A- Excavation materials within the area of dam body
and power house:
The volume of excavation materials of dam foundation, spillways, power house will reach 2 700 000 m3, from which only 60 percent (equal to 1 600 000 m3) will be used for sand material.
B- QU1 and QU2 quarries:
These quarries are located within 2 km range of downstream of dam axis and the volume of their material reaches 3.5 million m3.
C- Upstream quarries:
This quarry is located in the area of fourth unit of Saruk Sazand (upstream of batching plant location). It has a good volume of 4 million m3 suitable material.
The results of short term chemical and physical tests is generally satisfactory and the reactions of available material are alkaline-solicit and alkaline-carbonate. Therefore long term tests are being carried out in this regard. |
