New Cofferdam sealing technique saves excavation and concrete
In construction of vehicular tunnel under New River, Ft.Lauderdale, Fla, 4 ft thick tremie concrete slab was used to seal floor of cofferdam; 28 ft thickness would have been required of conventional gravity type slab; anchorage of thin slab to underlying bedrock with grouted bars; movable templet was used to hold sheet piles during driving.
