Technical Specifications

Iranshahr powerplant also known as Bampour powerplant with a total capacity of 740megawatts is one of the significant powerplants in Iran. It has two separate complexes;The gas plant and combined cycle plant. The Gas plant with a total capacity of 256 Megawatts and the combined cycle plant with a total capacity of 484 megawatts on a land of 48 hectares. The plant main fuel is gas and the secondary (standby) fuel is Mazut. Bolandpayeh service in this project is to design and build a standby buried Mazut tank with a capacity of sixty thousand cubic meters for the emergency situation of the plant. The tank has a cubic shape which divided into 4 equal parts. The foundation has a square shape with the side length of 93 meters. The thickness of the foundation beneath the columns is 70 centimeters and in the other area is 40 centimeters. he height of the walls and columns are 9.2 meters.


General works’ Quantity

Earth works 60,000 m³

Concreting 22,000 m³

Reinforcement 3,000 tons

Formworking 40,000 m²

The thickness of the walls at the base is 70 centimeters and changes to the top by 40 centimeters. The tank has 144 columns with a diameter of 1 meter. Full operative height of mazut in the tank would be 6 meters. The roof was executed using precast members. There are some corbels elements act as support of the precast members. After execution of the beams in

cast, the precast members were installed and the final concrete cover was poured onsequently.

A group of shear key elements was considered in the precast members to merge performance

of the precast members and the final concrete cover. The final level of the roof is about one meter higher than the natural
