- Description
- The spillway gates at McNary Dam are vertical lift, roller type gates. Each gate is 50 wide by 52 tall. Each gate consists of two leaves, a 27 tall upper leaf and a 25 tall lower leaf. The leaves are connected with a horizontal joint. Each ga te is equipped with 18 wheel assemblies, 9 wheels per side. A wheel assembly consists of a 27 diameter steel wheel rim, 8.5 wide, steel wheel flanges, bearing, steel axle shaft 4 long by 11 diameter, seals, retainers and bolts. All steel parts of the wheel assemblies are machined to size and finish. Work will be performed in the spillway gate storage and repair pits. When a gate is split in two, one leaf goes into the repair pit and the other leaf goes into the storage pit. Up to four gates are to be rehabilitated. Work will consist of removing all horizontal and vertical rubber seals (flat and J-seals) and installing new seals. The wheel assemblies are to be removed, disassembled, inspected and rebuilt, or replaced. Some wheel parts such as seals, retainers, and b olts are to be replaced with new parts. Some parts such as wheel rims may need to be rebuilt, may need to be replaced with new, or may be reusable without repair depending on inspection results. Portions of the upstream face of the gate and other specifi ed areas are to be painted with vinyl paint. Existing paint contains lead and must be removed where new paint will be applied. Fabricate and install some miscellaneous metalwork items on the gates. Machine the embedded gate guide slots in the spill bays where the rehabilitated gates are located.
