Abstract:

The performance of three proposed types of extruded rubber seals was evaluated for operating heads up to 80 ft of water in a 5-ft-wide, 11-scale test chamber. The head required to move an unrestrained seal into seating position against the upper seal plate and downstream miter gate sill varied from 0.2 to 0.5 ft. All the seals were satisfactory when straight and free of irregularities along the sealing surfaces. For a differential head of 5 ft, leakage varied from 0.003 cfs per lineal ft of straight seal to 0.030 cfs per ft when the center of an unstressed seal was warped 38 in. from a taut line between opposite ends of the test specimen.
