Repair, Evaluation, Maintenance, and Rehabilitation Research Program. Design of a Precast Concrete Stay-in-Place Forming System for Lock Wall Rehabilitation
The general approach to lock wall rehabilitation has been to remove 1 to 3 ft of concrete from the face of the lock wall and replace it with new air-entrained concrete. One of the most persistent problems using this approach is cracking in the replacement concrete. It has been postulated that by using precast concrete as a stay-in-place form for the replacement concrete, cracking problems can be eliminated. This report describes the design of such a forming system. A range of design alternatives was evaluated through a process of value engineering and horizontal precast panels constructed of conventional precast quality concrete were selected for detailed quantitative investigation. The panels are tied to the lock monolith along the top and bottom edges using form ties designed to support the loads of the infill concrete placement.
