| Abstract: | The reverse tainter valves at Pickwick Lock on the Tennessee River are being replaced. The original valves have experienced excessive repairs during their service life, so a new valve design is sought. A hydraulic physical model study has been conducted to collect flow and load information on the existing lock culvert valve and a proposed valve design. The proposed valve geometry is based on experience gained from other model and prototype studies of lock culvert valves. The loads on the trunnion, the axial load on the strut connecting the valve lift mechanism to the valve, and pressures along the culvert have been measured for both the existing and proposed valve designs. Using the information gleaned from all test results, a final valve design recommendation is provided. |
