Two sheet piles were driven 4 m apart into clayey sand, as shown in Figure 8.9, and a 2 m depth of soil between the two sheet piles was removed. To facilitate some proposed construction work, the region between the sheet piles is being dewatered where the water level is lowered to the excavation level by pumping out water con- tinuously.
