New or existing harbour wall reinforcement - has submerged pile wall built from elements and intervening drilled tubes

摘要

The structural support for harbour installations or bank consolidation is esp. applicable to drilling for base reinforcements for supporting or repairing e.g. jetty walls and similar. Tubes, open on both sides, are inserted at regular intervals, by drilling along, at a short distance in front of the existing jetty base under water, into the harbour bottom substructure. By use of wall elements fitting the spaces between the tubes, these are completed to form an underwater pile wall overlapping the existing jetty wall.
