Description
Technical field
This utility model is related to hydraulic engineering technical field, specifically a kind of efficient energy dissipating flood discharge overfull dam surface structure.
Background technology
Dam is block rivers current with raising of water level or adjusts the water retaining structure of flow, with regulated flow, flood control,
Supply water, generate electricity, etc. function.Dam flood discharge is often Hydraulic Engineering Design person's stubborn problem, and features as poor geologic condition, flip trajectory bucket are made
Into seriously wash away, can make bank slope collapse, or even threaten major project safety.Large reservoir flood-discharge energy-dissipating is even more very arduous
Task, traditional stream, underflow, bailing bucket stream chosen cannot receive good effect of energy dissipation.Dam flood-discharge energy-dissipating is always for a long time
It is problem that water economic system personnel pay much attention to.
Utility model content
In order to solve above-mentioned technical problem present in prior art, this utility model provides a kind of efficient energy dissipating flood discharge
Overfull dam surface structure, by overflow dam body, overfull dam surface, chooses stream arc bottom, low layer and chooses runner, high level and choose runner, high level and choose conductance stream
Road, high level choose runner cutwater composition, and described overfull dam surface reaches shunting when choosing stream arc bottom and chooses stream.
Further, described high level is chosen runner or so and is divided into two high levels and chooses conductance runner.
Further, described high level is chosen conductance runner and is directed to low layer being vertically and horizontally curved surface, earial drainage
Runner direction is chosen, low layer is thrown just by the jet after defrlector bucket and is chosen above the jet of runner.
When disclosed in this utility model, a kind of efficient energy dissipating flood discharge overfull dam surface structure is run, high level chooses penetrating for conductance runner
Stream is high thus near, and the jet that low layer chooses runner is low thus remote, high level choose the jet of conductance runner fall from above exactly pound it is low
Layer is chosen the gas strong collision of the jet of runner, two strands of current and entrainment, is blended, and plays, can be compared with
Solved because of features as poor geologic condition well, what flip trajectory bucket was caused seriously washes away, avalanche, or even threaten the problem of major project safety.

Specific embodiment
Below in conjunction with the accompanying drawings utility model is described further.
As Figure 1-4, a kind of efficient energy dissipating flood discharge overfull dam surface structure of the present utility model, by overflow dam body 1, overflow
Dam facing 2, choose stream arc bottom 3, low layer and choose runner 4, high level and choose runner 5, high level and choose conductance runner 6, high level and choose 7 groups of runner cutwater
Into the overfull dam surface 2 reaches shunting when choosing stream arc bottom 3 and chooses stream, and low layer is chosen 4 radius of curvature of runner and chooses stream cambered surface more than conventional；
High level is chosen 5 radius of curvature of runner and chooses stream cambered surface less than conventional；High level is chosen runner 5 or so and is divided into two high levels and chooses conductance runner 6；It is high
Layer chooses conductance runner 6, is vertically and horizontally being curved surface, and earial drainage is directed to low layer and chooses 4 direction of runner, by defrlector bucket
Jet afterwards is thrown just low layer and is chosen above the jet of runner 4.
During a kind of efficient 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 choosing stream arc bottom, runner is chosen through low layer and high level chooses the gas that runner is divided into two strands of current of height and entrainment, high level chooses stream
Honeycomb duct is oriented to low layer earial drainage and chooses runner direction, throws just low layer by the jet after defrlector bucket and chooses on the jet of runner
Side, the jet for choosing conductance runner due to high level are high thus near, and the jet that low layer chooses runner is low thus remote, and high level chooses conductance runner
Jet falls from above the gas strong collision of the jet for exactly pounding that low layer chooses runner, two strands of current and entrainment, blends, and plays
Energy effect is eliminated efficiently.
