Innovative Lock Design. Report 1. Case Study, New McAlpine Look Filling and Emptying System, Ohio River, Kentucky, Hydraulic Model Investigation

摘要

Navigation improvements planned for the McAlpine Lock and Dam project on the Ohio River provided the proto-type for the laboratory model used in this study. The model was used to evaluate the in-chamber longitudinal culvert filling-and- emptying system (ILCS). In the ILCS, lock filling and emptying culverts are placed inside the lock chamber rather than in the lock walls, resulting in significant savings in lock wall construction. The ILCS also features a through-the-sill intake and discharge outlet with a longitudinal in- chamber filling-and-emptying system. Various discharge systems for the ILCS were evaluated. Construction of the filling and emptying culverts on the lock floor between the lock walls was found to be a viable design.
