Piezometer Test Apparatus (Scale models, testing, and oddities) Item Info

North Coulee Dam, Piezometer Terminal Well, A view of the piezometer test apparatus at the corner of the upstream and right walls of the well. The pore pressure in the dam embankment and foundation are transmitted through the water-filled tubes and recorded on the Bourdon tube pressure gages at the right. The solenoid operated valve at the top transmits pulsating waves through the system to assist in the removal of air in the tubes. Two TK Westinghouse relays at the bottom are electrically connected in series with the solenoid valve. Any cycle desired for the operation of solenoid valve can be obtained by adjustments of the timing devices in the relays. The air trap at the upper left supplies water and removes air from the system. Specifications 2586, Contract I2r-18481, J.A. Terteling and Sons, Inc., Contractor.
