Custom-engineered for the existing intake slots, the Red Rock Falls slide gates are fixed gates that close entirely by gravity when pressure is equal upstream and downstream. Each gate is built from an upstream skin plate, horizontal structural members, side plates and intermediate stiffeners, assembled with continuous welds. The horizontal members are positioned to balance the hydrostatic load.Â
UHMW sliding pads keep the gate from jamming in its guides. A single-stem J-seal on the sides and bottom, with the bottom seal resting on the existing sill sealing surface, and upstream leaf springs provide the sealing. Black epoxy paint suitable for water immersion protects the gates against corrosion. They are handled with the existing follower beam and, within the guides, with the on-site jib crane.
