Measurement of Hydrostatic Uplift Pressure on Spillway Weir with Air Piezometers


Air-operated piezometers have been found suitable for measuring water pressure on the base of a concrete spillway weir. Hydrostatic pressure cells were embedded in native chalk; thin plastic tubing leads were extended through freshly poured, large-aggregate concrete. Sheet-brass barriers attached to leads with Flex fittings prevented piping. Operation for 2 1/2 years has been satisfactory.
