Book Innovative Lock Design Report 1 Case Study New McAlpine Look Filling and Emptying System Ohio River Kentucky Hydraulic Model Investigation

Download or read book Innovative Lock Design Report 1 Case Study New McAlpine Look Filling and Emptying System Ohio River Kentucky Hydraulic Model Investigation written by and published by . This book was released on 1998 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Navigation improvements planned for the McAlpine Lock and Dam project on the Ohio River provided the proto-type for the laboratory model used in this study. The model was used to evaluate the in-chamber longitudinal culvert filling-and- emptying system (ILCS). In the ILCS, lock filling and emptying culverts are placed inside the lock chamber rather than in the lock walls, resulting in significant savings in lock wall construction. The ILCS also features a through-the-sill intake and discharge outlet with a longitudinal in-chamber filling-and-emptying system. Various discharge systems for the ILCS were evaluated. Construction of the filling and emptying culverts on the lock floor between the lock walls was found to be a viable design.

Book New McAlpine Lock Flling and Emptying System Ohio River Kentucky Hydraulic Model Investigation

Download or read book New McAlpine Lock Flling and Emptying System Ohio River Kentucky Hydraulic Model Investigation written by and published by . This book was released on 2000 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: Navigation improvements at McAlpine Locks and Dam on the Ohio River include construction of another 365.76-m-(1,200-fl-) long lock chamber adjacent to the existing lock chamber. A previous model investigation of an in-chamber longitudinal culvert filling and emptying system (ILCS) with through-the-sill intakes and outlets revealed the ILCS design was feasible. The intake and outlet designs were changed and another model study, reported herein, was conducted to evaluate the hydraulic performance of the new design. The ILCS design was modified slightly from the previous study. Port extensions were added to some of the ports in the lower half of the chamber and the width of the wall baffle was increased. The filling time for acceptable chamber performance with these changes and the design lift, 11.28 m (37 ft), was 11.3 min. This filling time was achieved with a variable speed valve operation. A roof extension placed over the right intake was found to be beneficial in helping to reduce the strength of vortices that formed in the upper approach during filling operations.

Book Modernization of Filling and Emptying System Existing McAlpine Lock Old No 41 Ohio River Louisville Kentucky Hydraulic Model Investigation

Download or read book Modernization of Filling and Emptying System Existing McAlpine Lock Old No 41 Ohio River Louisville Kentucky Hydraulic Model Investigation written by Jackson H Ables (Jr) and published by . This book was released on 1967 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tests were conducted on a 1:25-scale model of the filling and emptying systems of the existing 600- by 110-ft lock of the McAlpine project. These tests were concerned with whether structurally feasible modifications of the systems would result in decreased turbulence and hawser stresses and thus permit faster filling and emptying of the lock.

Book Gallipolis Lock Intake Vortex Study Ohio River

Download or read book Gallipolis Lock Intake Vortex Study Ohio River written by Robert A. Davidson and published by . This book was released on 1987 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: The existing Gallipolis Locks are located on the Ohio River at mile 279.2. Because of their location on an inside bend, the orientation for approach channels, velocity currents in the river, and the design of the approach walls, entry of downbound tows into the lock is hazardous and time consuming during periods of high flow. As a result of increasing traffic and tow sizes, these locks have become a serious problem to vessel movement along the Ohio River. Replacement locks will be constructed in the near future to alleviate these problems. Tests were conducted on a 1:25-scale model that reproduced 2,500 ft of the Ohio River beginning 188 ft upstream of the existing lock guide wall. Approximately 250 ft of the width of the river was reproduced. This model was used to evaluate the performance of the intake structures for the new locks. Two different alternate plans for the filling of the locks were tested. One plan consisted of filling the lock through long culverts extending from the river to the lock chamber. The other plan consisted of an intake canal extending from the river to the guide wall. Two intakes were located on the riverward side of the new lock approach wall, and one intake was located in the filling canal. Air-entraining vortices developed at the intake structure in both plans. The air-entraining vortices observed in both plans were eliminated by modification to the intake structure.

Book Navigation Conditions at Mcalpine Locks and Dam Ohio River

Download or read book Navigation Conditions at Mcalpine Locks and Dam Ohio River written by Louis J. Shows and published by . This book was released on 1981 with total page 112 pages. 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.

Book Upper Mississippi River Lock Filling and Emptying System Hydraulic Model Investigation

Download or read book Upper Mississippi River Lock Filling and Emptying System Hydraulic Model Investigation written by and published by . This book was released on 2002 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Navigation improvements including lock extensions are being investigated for several existing projects on the Upper Mississippi River (UMR). A hydraulic model study was conducted to evaluate filling and emptying system design alternatives for the extension of lock No. 22 and lock No. 25. A 1:25 scale model was constructed to determine the range of lock performance for both locks. The filling system flow capacity was not significantly changed from the original non-extended lock design. The filling time for acceptable chamber performance with the 4.57-m (15-ft) lift was 23.1 min. This filling time was achieved with a 23-min valve. The focus of the study was to determine emptying performance for multiple options of emptying gates built in the extended portion of the lock chamber river wall. Several emptying system designs were studied. The type 2 and 3 design provided the best chamber performance during the emptying operation.
