| Abstract: | The gates for the Xiaolangdi sand sluice tunnels and orifice-plate tunnels adopt eccentric-hinged tainter gates, projected drop-sill slots and pressed type seal supported with double pre-pressed and hinged seal. Consequently, the problems of vibration, cavitation and erosion for the Xiaolangdi flood outlet gates due to high head, large flow rate and high silt content are properly solved. The smooth operation of the sand sluice and orifice-plate tunnels demonstrates that the eccentric-hinged tainter gates are safe and reliable. The installation procedure and method will provide reference for other similar projects |
