VERY HIGH RISE NAVIGATION LOCKS, PART 1

This article discusses the use of very high-rise locking systems to deal with water level differentials of 50 to 80 meters under circumstances involving heavy vessel traffic. The navigational rise can occur for such reasons as the construction of a hydropower plant or the linking of canals that lie in different hydrographic basins. Shiplifts and inclined planes are solutions in current use, but their dimensions prevent the navigation of large push-tow convoys without dismantling. The idea of high-rise locks as an alternate solution has therefore evolved. The lock, whose design is explained and is illustrated with drawings, resembles a large well, closed upstream by a retaining wall and downstream by a shield wall. The use of lateral basins built inside the walls successfully addresses the troublesome questions of water conservation, cavitation and surges.
