Miscellaneous; Closing End of Cofferdam
Description:
Original notes on slide: Turning the northeast corner to close cast end of cofferdam. This photograph shows the pockets being filled with material dredged from the harbor bottom. The water at this point is 15 feet deep. The corner pocket holds 300 cubic yards of saturated material. The great strength and watertight qualities of the interlocked joints of the Lackawanna Steel Sheet Piling are very apparent. The bowing of the piles under the existing pressures is limited by the clearance left in the interlock to overcome friction in driving.
