Fabricated energy dissipater structure suitable for flip flow energy dissipation
The assembly type energy dissipater structure comprises a honeycomb energy dissipation structure arranged in an energy dissipation scouring pit, the energy dissipation scouring pit is arranged on the downstream side of an overflow weir, the bottom of the honeycomb energy dissipation structure is fixed in the energy dissipation scouring pit, a plurality of energy dissipation cavities are formed in the honeycomb energy dissipation structure, and the honeycomb energy dissipation structure is arranged in the energy dissipation scouring pit. The multiple energy dissipation cavities form a honeycomb-shaped structure, and openings are formed in the tops of the energy dissipation cavities, so that water flow ejected by the overflow weir dives into the energy dissipation cavities to dissipate energy. The shear turbulent dissipation of the adjacent water streams can be enhanced, the energy dissipation effect is improved, and under the same Froude number, compared with a traditional flip flow energy dissipation structure, the energy dissipation efficiency is improved by 40%, so that the flip distance of the flip jet water flow can be shortened, and adverse effects such as flood discharge atomization and tail water fluctuation are reduced.
本发明提供一种适用于挑流消能的装配式消能工结构，包括设置在消能冲刷坑中的蜂巢消能结构，所述消能冲刷坑设置在溢流堰的下游侧，所述蜂巢消能结构的底部固定在消能冲刷坑中，所述蜂巢消能结构内设置多个消能空腔，多个所述消能空腔形成蜂巢状结构，所述消能空腔的顶部设置开口，使得从溢流堰挑射的水流下潜至消能空腔中进行消能。本发明能增强相邻水股剪切紊动耗散，提升消能效果，在相同弗劳德数下，较传统挑流消能结构，消能效率提高40％，从而可缩短挑射水流的挑距，减小泄洪雾化及尾水波动等不利影响。
