Repair, Evaluation, Maintenance, and Rehabilitation Research Program: Concepts for Installation of the Precast Concrete Stay-in-Place Forming System for Lock Wall Rehabilitation in an Operational Lock
Abstract
Previous efforts in the design of a precast concrete panel stay-in- place forming system for repair of navigation lock walls resulted in a limited implementation of this repair procedure in an actual lock. This development work, performed by ABAM Engineers, Inc., under a contract with the US Army Engineer Waterways Experiment Station, is described in two reports, REMR-CS-7 and REMR-CS-14. To extend the application of this repair procedure, additional work was undertaken to develop concepts for installation of stay-in-place forms in an operational lock. In an operational lock, it is not possible to dewater or lower the tailwater level, and thus, some wall rehabilitation work must be performed underwater. In addition, it is necessary for the work to be coordinated around scheduled lock openings, and all ancillary lock equipment must be maintained in an operational condition.
