Embodiment Construction
[0024] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:
[0025] Such as Figure 1-6 As shown, the flood discharge and energy dissipation structure of the high arch dam with narrow river valley and deep tail water of the present invention includes a dam body 1 on which an upper orifice 2 and a lower orifice 3 are arranged, so that the discharged water flow is stratified and the large differential outflow , the concrete apron 4 and the revetment 5 on both banks are set in the downstream of the dam. Wherein 2a is the upper orifice of the raised angle structure with a smaller angle, and 2b is the upper orifice of the depressed angle structure with a smaller angle. The lower orifice 3 is a slit-type middle hole with a flat bottom angle, contraction on both sides, and vertical diffusion.
[0026] In order to reduce the intensity and scope of the impact of flood discharge atomization and control the locati...
