Project: Indira Sagar Dam – Roller Bucket – NHDC, Khandwa

 

Details: The dam has a height of 91 mter and a capacity of 12 billion cum. It has 20 gates, with 12 radial gates and 8 auxiliary gates.

 

Challenge: The roller buckets of the radial gates were damaged due to excessive force of the discharged water through spillways.

 

Solution: Stagnant water in the buckets was dewatered by heavy duty water pumps and loose concrete was removed by chipping. Additional reinforcement was laid by anchoring bars into the existing concrete.
