16 Hydroelectric Dam Conversion With Diaphragm Walls,
The construction of the Red Rock Hydroelectric Project in Iowa required extensive
water and earth-retention systems to maintain integrity of an existing dam that was
converted. Key geotechnical features of the winner of DFI's Outstanding Project
Award included extensive excavations upstream and downstream of the dam,
cement and chemical grouting to treat solution features in the rock, and a 69 ft (21 m)
high cantilevered diaphragm wall upstream to retain the embankment dam
alongside a new water intake channel.
