Abstract

The one-to-one ratio of height to width of cellular cofferdams makes their use effective in the construction of dams and other projects on rivers. Freestanding cellular cofferdams, without stabilizing inside berms, have been built to a height of 115 ft (35 meters). Figure 7–1 shows the cofferdam for the Markland Powerhouse. This layout was accomplished with a double row of 62-ft (18.9-meter)-diameter cells upstream. Sheetpiles 115 ft (35 meters) long were used for the outside sheets of the cells on the water side. These sheetpiles reached rock and provided an effective water cutoff.
