Using above-mentioned combined energy dissipater, water flow enters from reservoir through sluice, flows through the overfall dam dam crest, first passes through described
Energy dissipating step makes water flow by resistance, and choosing rolling up and down occurs between the marking time of the energy dissipating step, and water flow is by two before
First fluidised form becomes the concurrently raw consumingly turbulent fluctuation of ternary fluidised form, while mixing a large amount of air, to reach certain energy dissipating effect；
Then water flow passes through the flaring gate pier, is retracted flip shot into air, comes into full contact with again with air, further realize and disappear
Energy；Last water flow flows through the ogee section and enters stilling pond, further promotes energy dissipating.
Preferably, the section shape of marking time of the energy dissipating step be long axis be 2-2.5m, short axle be 1.25-1.75m, from
Heart rate is 0.5-0.85 to erect elliptical lower portion.
Preferably, trapezoidal pier and T shape pier are provided in the stilling pond.
Preferably, the trapezoidal pier is located in front of the T shape pier, and horizontally-parallel with the T shape pier 1.
Preferably, the trapezoidal pier, the T shape pier are arranged side by side multiple.
Water flow flows through after the ogee section enters stilling pond, successively passes through the trapezoidal pier and T-type pier, generation is mutually touched
It hits, to greatly enhance the turbulent fluctuation shearing and blending effect inside water flow, the kinetic energy of water flow is made more to be converted to thermal energy.
Preferably, overfall dam dam crest surface is convex arcwall face.
Preferably, which is provided with abutment wall.
Preferably, the flaring gate pier is conventional X-type flaring gate pier or Y type flaring gate pier.
The beneficial effects of the present invention are:
1, the energy dissipating step of the combined energy dissipater marks time cross sectional shape to erect elliptical lower portion, and water flow is made to flow through energy dissipating step
Shi Fasheng more violent ternary hydraulic jump, contacts more abundant with air, and energy dissipating efficiency is largely increased, and can effectively shorten and disappear
The length of energy step, reduces project amount and project cost.
2, the combined energy dissipater which has a compact structure and a reasonable design, improves energy dissipating efficiency, while realizing abundant energy dissipating.
