 | Construction of the Merowe Dam in Northern SudanStabilization of Radial Gates at Merowe Dam Using DYWIDAG Post-Tensioning Systems, Hamdab, Northern SudanConstruction of the Merowe Dam on the River Nile in Northern Sudan, 350km north of the capital of Khartoum, began in 2003. With its total length of approximately 9.2km and its hydropower capa city of 1,250MW, the Merowe Dam will be the second largest dam on the Nile after the Assuan Dam.
The dam is to provide electricity, provide irri - gation for the creation of new farmland, protect against flooding and reduce problematical sedimentation in the Assuan Dam located about 350km downstream.
The 154m long and 67m high spillway with its radial gates and the 370m long power station are at the core of the rockfill dams on each side. Construction cost is estimated to be around 555 Million Euros, with another 575 Million Euros to be added for the power station.
For anchoring the trunnion girders to the radial gates, DSI delivered a total of 4 x 27 = 108 pieces of 32mm St930/1080 DYWIDAG Post- Tensioning Bars in lengths between 6.0m and 11.20m with bilateral plate anchorages. All in all, the spillway dam contains 12 lower and 2 upper flood spillways where the water level can be regulated by means of the radial gates in times of critical flooding.
In addition to the supply of material, DSI assisted the client by supervising the installation, tensioning and grouting of the DYWIDAG bar tendons. |
