Innovative Repairs to Steel Sheet Pile Structuresby David L. Porter, Childs Engineering Corp, Medfield, MA, USA,
Abstract: Several unique and many unusual repair techniques have been used to structurally rebuild steel sheet pile walls. An example of a unique repair to a cellular cofferdam utilizing a suspended annular ring of steel piles where the annular space is filled with concrete is presented. This repair solution provided a significant cost savings when compared to conventional repair methods. Several unusual solutions for rehabilitation of tied-back steel sheet pile walls are examined. One repair illustrates replacement of an existing tied-back bulkhead by installing a new steel sheet pile wall behind the existing tied-back bulkhead. Another solution extends the life of an existing deteriorated steel sheet pile wall by installing lightweight fill to reduce lateral earth pressure.
