Lock Design, Bottom Longitudinal Filling and Emptying System

摘要

This report presents and summarizes directions for design of bottom longitudinal filling and emptying systems for navigation locks. Even though additional refinements to the system are desirable, the bottom longitudinal filling and emptying system unquestionably is the best system for intermediate- and high-lift locks used to date by the Corps of Engineers. It not only is superior when operated as planned but also is inherently safer than other systems in that it is not sensitive to faulty operation of the valves.
