In-Chamber Longitudinal Culvert Design for Lock Filling and Emptying System
Abstract
The U.S. Army Corps of Engineers is planning navigation improvements for many projects to meet predicted increases in tow traffic. Some of these improvements include the addition or replacement of the navigation lock. Innovative design and construction techniques are being investigated for reducing construction costs, as well as operation and maintenance costs. The Corps identified that a savings in lock construction could be achieved if the conventional concrete gravity lock walls with culverts inside them could be replaced with thin walls and longitudinal culverts located inside the chamber. This culvert design was designated the In-chamber Longitudinal Culvert System (ILCS). This report provides the results of research conducted under Work Unit 33140, "In-Chamber Longitudinal Culvert Design for Lock Filling and Emptying Systems," of the Innovations for Navigation Projects Research Program. Design guidance for the ILCS is provided for low- to medium-lift locks. The guidance includes culvert location; port size, location, and spacing; port extensions; roof overhang; and wall baffles. Guidance is also provided for modified ILCS designs and single-culvert designs. Lock chamber performance guidance, based on acceptable filling and emptying operations, is also included. The results show that the ILCS is a feasible design based on the hydraulic performance determined from the investigation.
