This book was released on 1961 with total page 49 pages. Available in PDF, EPUB and Kindle. Book excerpt: Greenup Dam spillway (now being constructed on the Ohio River) will consist of nine 100-ft-wide gate bays, flow through which will be regulated by five submergible and four nonsubmergible tainter gates. A horizontal apron surmounted by baffle piers and an end sill will dissipate energy created by flow passing over or under the tainter gates. Bulkheads will be provided for emergency closure of the spillway bays. Investigations conducted in a 1:25-scale section model reproducing one gate bay and adjacent half bays were concerned with: (a) hoist loads and vibration tendencies of the submergible tainter gate; (b) the performance of the stilling basin below both the submergible and nonsubmergible gates; and (c) hydraulic forces acting in a vertical direction on the emergency bulkheads when they were operated in one-, two-, three-, and four-bulkhead units.

This book was released on 1961 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: Model investigations of the spillway for Markland Dam were concerned initially with a design using a split-leaf vertical-lift gate, and finally with a design using five submergible and seven nonsubmergible tainter gates. Section models reproducing one gate bay and adjacent half gate bays at scales of 1:36 (vertical-lift gate) and 1:25 (tainter gates) were used for study of gate hoist loads and vibration tendencies due to hydraulic forces, and stilling basin performance. Also, a 1:4-scale model of a section of the face of the submergible tainter gate and the downstream face of the gate sill was used for detailed study of pressure conditions and observation of the behavior of an inflatable-type bottom seal for the gate. A satisfactory design for the more economical plan using tainter gates was developed. Loads on the submergible tainter gate due to hydraulic forces were not excessive, and with the top of the gate shaped so as to ensure positive pressures, oscillation of the gate is considered unlikely. Tests in the 1:4-scale model revealed that the gap between the face of the gate and the gate sill must not flare more than about 1 in. in order to maintain relatively stable pressures on the gate and sill. Tests of the bottom seal disclosed undesirable flutter when the seal was deflated and the gate submerged; this seal was abandoned for Markland Dam.

Available in PDF, EPUB and Kindle. Book excerpt: Model tests were conducted on a 1:36-scale section model which reproduced one central gate bay and approximately half of each adjacent gate bay. Tests were conducted on spillways utilizing both submergible and nonsubmergible tainter gates. Tests were concerned with weir crest shape, discharge characteristics, gate radius and trunnion position, stilling basin performance, and riprap requirements downstream from the stilling basin.

Available in PDF, EPUB and Kindle. Book excerpt: McAlpine Locks and Dam are located on the Ohio River near Louisville, Kentucky, 606.8 miles below Pittsburgh, Pennsylvania. The locks are located in a bypass canal on the left overbank landward of Shippingport Island. A powerhouse is located along the left bank adjacent to the downstream end of Shippingport Island, and a four-gated spillway section is located adjacent to the powerhouse. A fixed-crest weir extends for the four-gated spillway section upstream 6,600 ft generally parallel to the right band to an upper five-gated spillway section which is connected to the right bank with a 1,200-ft-long fixed-crest weir just upstream of the Pennsylvania Railroad bridge. The structures, designed to maintain a minimum upper pool during low flows extending about 75 miles upstream to Markland Locks and Dam near Warsaw, Kentucky, include a navigation lock with clear chambers dimensions of 110 ft wide by 1,200 ft long located at the lower end of a 1.75-mile-long canal along the left bank and two auxiliary locks between the main lock and left bank that are out of service. A fixed-bed model reproduced about 8.5 miles of the Ohio River channel, the lock approach canal, and adjacent overbank areas to an undistorted scale of 1:120.
