Underwater Inspection and Repairing of the Stilling Pools in Gaobazhou Hydropower Station

Processes and techniques adopted in the underwater inspection and repairing project of the stilling pools in Gaobazhou Hydropower Station are introduced.Two different stilling pools, the bucket type stilling pool and the under-flow stilling pool with Rehbock dentated sills, are used respectively for the surface outlets and the deep outlets to protect the downstream river bed, river bank and the dam toe from scouring.Thus, it is important to regularly carry out under-water inspection and underwater repairing if necessary on the stilling pools.
