Description
Technical Field
The invention belongs to the field of hydraulic and hydroelectric engineering, and particularly relates to a flip bucket and a drainage structure thereof.
Background
The flip energy dissipation technology is suitable for a high and medium water head pivot of a rock foundation, and the flip bucket can adopt an equal-width continuous flip bucket, a differential flip bucket, a diffusion flip bucket, a narrow-slit contraction flip bucket, a special-shaped flip bucket and the like according to a water head, a discharge amount and a terrain. The flip bucket usually consists of a bottom plate, a left side wall and a right side wall, and the tail end of the flip bucket needs to be provided with an inverse arc shape so as to throw a large stream of high-speed water flow into the air to fall like a human riverbed near the center of the riverbed. The trajectory bucket can sink water flow before the water flow is picked up, and similarly, after the flood discharge is completed and the upstream gate is closed, the final water flow can sink in the trajectory bucket due to the fact that the trajectory bucket cannot be picked up, and accumulated water is formed. In addition, rain and rain water can also cause water accumulation in the flip bucket.
Ponding in the flip bucket has certain harm to flip bucket structure safety, mainly reflects in:
1) the accumulated water in the flip bucket causes the concrete which is soaked in the water for a long time to be saturated, in winter, particularly in cold areas, the pore water in the concrete can expand after being frozen, namely, the frost heaving phenomenon occurs, repeated freeze-thaw cycle easily causes damage to the concrete structure, damage is generated, and once damage is generated, the damage to the flip bucket is rapidly expanded under high-speed water flow during flood discharge.
2) The accumulated water body in the flip bucket can also generate freeze-thaw cycle, and the frozen water body can generate frost heaving additional stress on the side walls on the left side and the right side of the flip bucket, so that cracks are easily generated on the side walls on the left side and the right side, particularly the root, and once the cracks are generated, the water body can become a cavitation source under high-speed water flow, and the water body is rapidly deteriorated to cause structural damage.
3) The existence of ponding in the flip bucket for flip bucket structure can appear two parts on water under water and on water, and in summer high temperature season, can form temperature stress, especially the concrete near the surface of water interface changes greatly because of temperature gradient, appears the temperature crack very easily, in case form the crack, also can become cavitation erosion source when the flood discharge, and the crack expands rapidly and develops into a big dashing hole even, leads to flip bucket structural component to destroy, endangers operation safety.
4) Regardless of whether the drift bucket concrete is frozen and swollen to damage or cracks are generated, once the cracks occur, flood discharge safety is seriously damaged, and the operation and maintenance cost can be increased.
When flood discharge is carried out, the water flow speed is as high as 40m/s, and some water flow speeds even exceed 50m/s, the cavitation number of the water flow is greatly reduced, so that serious cavitation damage is often generated at certain flow passing parts of a water discharge structure, and the strength of the cavitation damage is approximately proportional to the 5-7 th power of the water flow speed. Cavitation erosion not only damages the overflowing surface of a leaking building, influences the overflowing performance, reduces the leaking capacity, and can cause the leaking building to be incapable of normally operating in severe cases, even cause vibration, and cause engineering damage and the like, so that the cavitation erosion damage caused by high-speed water flow needs to be overcome when a drainage structure is arranged under the condition again.
