Embodiment 1
[0021] The engineering overview of embodiment 1 and comparative example 1 is as follows:
[0022] A power station is built in a narrow river valley, with steep mountains on both sides, and the downstream river gradually narrows. The upstream water level elevation of the reservoir is 762.30m, the downstream water level elevation is 672.30m, the drop is 90m, and the flood discharge flow is 320m 3 / s.
[0023] Aiming at the above projects, two energy dissipation systems of Example 1 and Comparative Example 1 were used to carry out hydraulic model tests.
[0024] Example 1
[0025] The energy dissipation system of the suspension drop-flow pad pond described in this embodiment includes a three-level pad pond 2 arranged at different elevations of the mountain body on the side of the reservoir dam body and an upstream diversion channel 1 leading out the water in the reservoir; the above-mentioned facilities layout as figure 1 , figure 2 , image 3 As shown, the axes of the wate...
