Description
Technical field
The present invention relates to hydraulic engineering technical field, specifically a kind of efficiently energy dissipating flood discharge overfull dam surface structure.
Background technology
Dam is block rivers current with raising of water level or the water retaining structure of regulation flow, have regulated flow, flood control,
Supply water, generating, etc. function.Person's stubborn problem that dam flood discharge may often be such that Hydraulic Engineering Design, features as poor geologic condition, flip trajectory bucket is made
Become seriously washes away, and can make bank slope collapse, even threaten major project safety.Large reservoir flood-discharge energy-dissipating is the most arduous
Task, traditional choose stream, underflow, bailing bucket stream and all cannot receive good effect of energy dissipation.Dam flood-discharge energy-dissipating is the most always
It is the problems paid much attention to of water economic system personnel.
Summary of the invention
In order to solve above-mentioned technical problem present in prior art, the invention provides a kind of efficiently energy dissipating flood discharge overflow
Dam facing structure, by overflow dam body, overfull dam surface, choose stream arc at the bottom of, low layer chooses runner, high level chooses runner, high level chooses conductance runner, height
Layer chooses runner cutwater composition, and described overfull dam surface arrives shunting when choosing at the bottom of stream arc and chooses stream, and low layer is chosen runner radius of curvature and is more than
Routine chooses stream cambered surface, and high level is chosen runner radius of curvature and chosen stream cambered surface less than routine.
Further, described high level is chosen and is divided into two high levels to choose conductance runner about runner.
Further, described high level is chosen conductance runner and is vertically and horizontally being curved surface, vertical for earial drainage to choosing
While Qiing, level chooses runner direction to earial drainage guides low layer, just throws low layer by the jet after defrlector bucket and chooses runner
Jet above.
When one disclosed by the invention efficient energy dissipating flood discharge overfull dam surface structure is run, the jet that high level chooses conductance runner is high
Thus near, it is low thus remote that low layer chooses the jet of runner, and high level is chosen the jet of conductance runner and fallen from above and exactly pound low layer and choose
The jet of runner, two strands of current and the gas strong collision carried secretly, blending, play and efficiently eliminate energy, can be preferably
Solving because of features as poor geologic condition, what flip trajectory bucket caused seriously washes away, avalanche, the problem even threatening major project safety.

Detailed description of the invention
Below in conjunction with the accompanying drawings invention is described further.
As Figure 1-4, a kind of efficiently energy dissipating flood discharge overfull dam surface structure of the present invention, by overflow dam body 1, overfull dam surface
2, choose stream arc at the bottom of 3, low layer chooses runner 4, high level chooses runner 5, high level chooses conductance runner 6, high level is chosen runner cutwater 7 and formed, institute
Stating overfull dam surface 2 to arrive shunting when choosing at the bottom of stream arc 3 and choose stream, low layer is chosen runner 4 radius of curvature and is chosen stream cambered surface more than routine；High level is chosen
Runner 5 radius of curvature chooses stream cambered surface less than routine.High level is chosen runner about 5 and is divided into two high levels to choose conductance runner 6.High level chooses stream
Honeycomb duct 6, is vertically and horizontally being curved surface, earial drainage guides while earial drainage is provoked low layer and chooses runner 4 direction, logical
Cross the jet after defrlector bucket just to throw low layer and choose above the jet of runner 4.
During a kind of efficiently energy dissipating flood discharge overfull dam surface arrangement works, current go out from overfall dam overhead stream, by under overfull dam surface
Letting out and choose at the bottom of stream arc, choose runner through low layer and be divided into two strands of current of height and the gas carried secretly with high-rise runner of choosing, high level chooses stream
Earial drainage level is chosen runner direction, by penetrating after defrlector bucket to guiding low layer vertical for earial drainage while provoking by honeycomb duct
Stream is just thrown low layer and is chosen above the jet of runner, and due to high level, to choose the jet of conductance runner high thus near, and low layer chooses runner
Jet is low thus remote, and high level is chosen the jet of conductance runner and fallen from above and exactly pound low layer and choose the jet of runner, two strands of current
And carry secretly gas strong collision, blending, play and efficiently eliminate energy.
