Description
Technical field
The invention belongs to Hydraulic and Hydro-Power Engineering technical field, it is related to a kind of three-dimensional underflow energy dissipator, more particularly to a kind of plum
The three-dimensional underflow energy dissipator of flower stake-high-low plate pattern, is applied to the disspation through hydraudic jimp in outlet structure escape works downstream.
Background technology
In Hydraulic and Hydro-Power Engineering, build hydraulic structure so that upstream and downstream formed the height of water so that with very big
Potential energy difference, leads off to most of potential energy during downstream and is necessarily converted into kinetic energy, and riverbed and riverbank are caused to wash away, and destroys ground,
Outlet structure escape works safety in itself is threaten, engineering measure need to be taken to control Current connectin and the energy dissipating in downstream.
The main task of energy dissipation measure is to try to consumption of energy in current internal drag and external drag, to greatest extent
Limit the effect of its erosion damage, or take control current measure current are chosen from outlet structure escape works, make its wash away riverbed but
The safety of building and neighbouring bank slope will not be influenceed.Conventional form of energy dissipater has at present：Choose streaming energy dissipating, underflow energy dissipation,
Four kinds of modes such as the energy dissipating of surface current formula and Dissipation Energy in Solid Bucket.The mode of wherein disspation through hydraudic jimp is more ripe, is by dam site downstream
The protection-apron of certain length is set, is set bank in apron end or is lowered protection-apron elevation formation stiling basin, current is produced in stiling basin
Unboiled water jumps, and by the effect energy dissipating such as the rotary roll of current, friction, shock and aeration, disspation through hydraudic jimp has safe and reliable, fluidised form steady
The advantages of fixed, downstream washes away smaller, fogging problem and gentlier avoids the formation of rainfall, and it is less demanding to geology, it is particularly well-suited to ground
The situation that matter condition is poor, riverbed impact resistance is low.
When height of dam is relatively low, when discharge per unit width is larger, the effect of energy dissipation of disspation through hydraudic jimp is poor, and energy dissipation rate is relatively low, and underflow disappears
The protection-apron of certain length can need to be built, cost is higher, need to be by setting up its supplementary devices, common mainly toe in energy dissipation tank
3 kinds of principal modes such as pier, energy dissipation pier, tail sill.When higher for energy dissipation rate requirement, toe pier, energy dissipation pier, tail sill etc. need to be set various auxiliary
Help energy dissipater to be applied in combination, and be to make moderate progress to the raising of energy dissipation rate, smaller is influenceed on current drag overall, and engineering into
This is but increased considerably.
The content of the invention
In order to solve the above-mentioned technical problem, the present invention is for based on flow characteristics, it is proposed that one kind improves disspation through hydraudic jimp rate
Peg board plane interlock with facade its supplementary devices for combining.
The technical solution adopted in the present invention is：A kind of peg board plane is interlocked its supplementary devices for combining with facade, and it is special
Levy and be：3 grades of sheet-pile structures are placed equidistant in the stiling basin in earial drainage weir downstream, the sheet pile dislocation cloth that space structure interlocks is formed
Put, current rotary roll is occurred, reach the effect of multistage auxiliary energy dissipating；The sheet-pile structure by some energy dissipatings stake and its a structure of an essay
If high-low plate composition, be arranged on the same cross-section of river.
