Hydraulic jets sink Carquinez caissons
Building of substructure of Carquinez bridge across San Francisco Bay; sinking big, open caissons through 90 ft of tidal currents and 45 ft of mud, sand, and gravel to bedrock; hydraulic monitors and air lift pumps remove soft bottom material; precast concrete panels serve as exterior wall forms: concrete distributors reach out 30 ft and rotate through 360° to feed concrete for "egg crate" caisson walls; shaped charges blast out hard bedrock.
