Operating Forces on Sector Gates under Reverse Heads: Hydraulic Model Investigation.
Abstract
Several sector gate locks in southern Louisiana (Bayou Boeuf, Freshwater, and Calcasieu) have experienced operational difficulties during reverse heads of 1.0 ft or greater. A 1:20-scale model with one set of gate leaves was constructed to measure forces acting on sector gate during reverse heads, develop feasible modifications for elimination of stall at existing structures, and test a gate of new design for use in future structures. Observation of free gate movement (original Bayou Boeuf gate) revealed forces tending to resist opening of the gate under reverse head conditions and to open the gate under normal head conditions. Model force measurements were made using a plus or minus 20-lb load cell rigidly connected to the center of a free gate leaf on a tangent and 42.5 ft from the pintle. (Author)
