Abstract : Prototype tests of the emergency bulkhead gate at Hulah Dam were conducted to determine its effectiveness in stopping flow for various control gate positions. The bulkhead consistently stopped at a position approximately 2 ft above the seat for every opening of the control gate. Measurements of downpull and acceleration revealed that an average peak hoist force of 22,500 lb occurred with the control gate full open and a bulkhead position of 5.8 to 7.0 ft above the seat. A maximum acceleration of 185 in./sec squared (0.5g) was recorded with the control gate full open and the bulkhead 6 ft above the seat. (Author)
