Description
Technical field
The present invention relates to build downstream rectification pier jointly for a kind of current stabilization energy dissipator in hydraulic engineering, more particularly to kind pump lock
Structure, it is applicable to the energy dissipation below spillway of such hydraulic engineering.
Background technology
The current urban water supply demand in China just gradually increases, and increasingly huger supply and drain water system causes pump lock quantity violent
Increase.In Plain lock station hydraulic engineering project playout, arrangement is built at lock station point good flow condition, but its floor space
Greatly, the problems such as easily causing earth clearance difficulty and high construction investment.Therefore, sluice, the pumping plant knot runed counter to traditional arrangement mode
The new arrangement closed is just shown one's talent.The form that pump lock is built jointly can effectively utilize land resource, at the same reduce operation with
And the expense cost required for management, widely promoted in hydraulic engineering.Pump lock is compared with common sluice, is one
Complex comprehensive engineering.But the problem of being arranged due to structure, phenomena such as backflow, bias current be present.It is each independent at lock station
During operation, flow direction forms an angle with riverbed shape, so as to change the fluidised form in former river course and MOMENTUM DISTRIBUTION, makes riverbed or so
Momentum imbalance, cause violent backflow and lateral current in hinge upstream and downstream, be degrading sluice pumping plant Inlet flow pattern, so that
Sluice discharge capacity or efficiency of pumping station reduce, or even serious scour bank slope, jeopardize building basis, threaten engineering safety.Therefore,
The device of a kind of energy dissipating and current stabilization is provided, there is Research Significance.
Utility model content
Problem to be solved in the utility model is to provide a kind of downstream rectification pier structure built jointly applied to pump lock, the dress
Energy dissipating and current stabilization can be carried out in the lock station exit in actual hydraulic engineering by putting, to obtain uniform and stable current, from
And effectively improve flow-shape.
To achieve the above object, the utility model takes following technical scheme：A kind of downstream for building jointly applied to pump lock is whole
Flow pier structure, it is characterised in that including from the forebay section in upstream to downstream, intake pool section, figure of standing, rectification pier, water outlet
Pond section, the rectification pier are arranged at discharge bay section downstream position, and the rectification pier is some hexahedron type rectification pier blocks, rectification pier
For symmetrically arranged delta structure, delta structure includes middle rectification pier block and left and right sides pier block.It is mainly used in pump lock
Symmetrical " lock+pump+lock " layout pattern built jointly, pump lock engineering longitudinal direction is from inside to outside respectively by forebay（Protection-apron）
Section, intake pool section, body of standing（Lock head）Section, rectification pier, discharge bay（Stiling basin）Section.Described rectification pier is swum out of under can reducing to disappear
The secondary shearing fallen and form rapids zone, downstream both sides sluice flow formation alternatively swinging in a big way be present in power water stream
Stream, reduce due to torrent exist caused by downstream control section velocity flow profile it is uneven, local velocity is excessive, so as to meet work
The problems such as Cheng Kangchong conditions.
Preferably, the rectification pier is reinforced concrete structure in Practical Project, need to ensure surfacing, so as to subtract
The surface breakdown phenomenon that weep souring is brought.
Preferably, the rectification pier is arranged at discharge bay diversion pier downstream position, and middle rectification pier block downstream protrudes,
And face is parallel with downstream aileron downstream, length is that unilateral lock is wide by 1/3, and width is that unilateral lock is wide by 1/6, and pier is high to be can be set and the power that disappears
Pond bank height is identical.
Preferably, pier block and unilateral lock station width parallel at left and right sides of the rectification pier block, width x length and height with
Middle rectification pier block is identical, so as to carry out the Dissipation of Energy of water outlet current.
Preferably, the middle rectification pier block is set away from that need to form certain distance, distance with left and right sides pier block centre
It is wide for 1/12 unilateral lock, so as to carry out water energy dissipating to the current through being let out under gate.
The beneficial effect that the utility model is reached：A kind of downstream rectification pier structure built jointly applied to pump lock passes through
In stiling basin, the secondary of stiling basin water outlet can be adjusted to a certain extent and is fallen and the swing of shear flow, changes downstream control
The velocity flow profile of section.Water through being let out under gate flows through the regulation of over commutation pier, and the vertical velocity flow profile of current is adjusted
It is whole, the diffusion of current is promoted, strong eliminates hydraulic jump phenomenon so that the kinetic energy of current reduces, so as to reach improvement current
The purpose of fluidised form；A kind of downstream rectification pier structure built jointly applied to pump lock can use in hydraulic engineering, have dress
Simple structure is put, stable performance, reliability is high, low cost and other advantages, has promotional value.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Embodiment
The utility model is further described below in conjunction with the accompanying drawings.Following examples are only used for clearly illustrating this
The technical scheme of utility model, and the scope of protection of the utility model can not be limited with this.
As shown in figure 1, a kind of downstream rectification pier structure built jointly applied to pump lock, it is characterised in that before it includes water inlet
Pond（Protection-apron）Section 1, intake pool section 2, body of standing（Lock head）Section 3, discharge bay（Stiling basin）Section 4, rectification pier 5.Wherein described rectification
Pier 5 is arranged at the downstream position of stiling basin 4.Described rectification pier 5 swims out of the current of stiling basin 4 and secondary fall simultaneously be present under can reducing
Formed in a big way rapids zone, cause water-flow equation it is uniform.The rectification pier 5 is arranged at discharge bay diversion pier downstream position, in
Between rectification pier block downstream protrude, and face is parallel with downstream aileron 6 downstream, at left and right sides of the rectification pier block pier block with it is unilateral
Lock station width parallel.Water body from upstream enters downstream area by sluice at left and right sides of river course, due to lock chamber position
In river course both sides, upland water gradually shunts to both sides, separates in pump lock near pier, and flow direction-changing is larger, separates around pump lock
Downstream is flowed into lock chamber after pier, and produces the obvious water surface in lock chamber and stiling basin and falls, when incoming water body is by whole
When flowing pier, current strong turbulent fluctuation, blending in being produced under the barrier effect of rectification pier, and under the shear action inside current,
So that producing strong shearing friction and collision inside current, kinetic energy and flow velocity reduce, and improve flow-shape so as to reach
Purpose.
Described above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of the utility model technical principle is not departed from, some improvement and deformation can also be made, these change
Enter and deform and also should be regarded as the scope of protection of the utility model.
