High dam reservoir ultra-deep water retaining and emptying system and operation method thereof
The invention discloses a high dam reservoir ultra-deep water retaining and emptying system and an operation method thereof. The water retaining and emptying system comprises first to last stage gate systems and a last stage radial gate system, and the first to last stage gate systems are sequentially arranged on a tunnel; each stage gate system is provided with communicating pipes with water supplement and draining functions, and the communicating pipes perform water flow control by means of valves; all the stages of gate systems achieve water pressure and air pressure balance through the inner and outer communicating pipes, the outer maintaining communicating pipes, ventilation pipes, galleries and the like of the gate systems respectively; the last stage gallery is communicated with the down stream of the water retaining and emptying system through a gallery shaft. The operation method includes four working conditions of water storing, water emptying, maintaining and water retaining. According to the high dam reservoir ultra-deep water retaining and emptying system and the operation method thereof, multiple stages of gates are disposed so as to share burden with a gross head; water filling is performed in rear of each stage of gate so as to counteract the pressure of water retaining heads, and hydraulic thrust which each stage of gate tolerates can be kept within a conventional design range; the defects of metal structures in the prior art can be overcome; the key technical problem of ultra-deep water retaining and emptying designs in the high dam reservoir engineering can be solved.
