The present invention is described in further detail with reference to the accompanying drawings and detailed description：
As shown in figures 1-4, the power station generating water diverting structure arrangement for taking into account environmental protection and sand discharge demand of the invention,
Diversion system including side arrangement of pulling in shore, blocking dam, blocking dam 1 is located in river course, reserved by riverbed main flow position on blocking dam 1
Jagged 2, dash and sand prevention bank 4 are set before the intake gate 3 of the diversion system of side arrangement of pulling in shore, the dam body of blocking dam 1 can be freely
Overflow, the two sides crest elevation of blocking dam 1 meets to be generated electricity when flood season power station is completely sent out quotes water level requirement needed for flow, while meeting
Flow rate of water flow is more than required water level requirement during bed load sediment median particle diameter start velocity in flood season storehouse.
Specifically, be arranged in river course, the highly relatively low two sides crest elevation of blocking dam 1 is high, just to channel thread portion
The position elevation of breach 2 is low.
The blocking dam 1 should be close proximity to arrangement with the distance of intake gate 3.
The dam location of blocking, answers choice arrangement gradient in river course to be more than bed load sediment median particle diameter critical grade
Scope, is typically chosen in the scope of gradient maximum in river course.
The blocking dam two sides crest elevation being arranged in river course is high, just low to main stem position breach elevation.
The blocking dam dam body maximum height is relatively low, is 2~5 meters, and the influence to environment is small.Dam body is highly determined along river
It is small to dam body maximum bottom width, it is not required to set fish rest pond.The setting of its two sides crest elevation, when should meet flood season power station and completely sending out
Generate electricity and quote water level requirement needed for flow, should also meet in flood season storehouse flow rate of water flow and start stream more than bed load sediment median particle diameter
Required water level requirement when fast.
The position of breach should be located in the range of channel thread on the blocking dam, as fish pass, ecological flow, silt conveying
Deng passage；The Yokogawa of breach should meet requirement of the fish migration to upstream and downstream head and flow velocity to width, and width is generally 1
~4m, breach should take into account sand discharge simultaneously and dry season releases ecological flow demand.
The dam body of the blocking dam can free overflow, the ecological flow generate electricity and quote flow superfluous water amount, released from and river
Come under husky dam body spilling and breach by blocking dam to let out in water.Its section need to meet steady demand and upstream and downstream are arranged as
Answer the gradient, generally 1:0.3~1:0.7, dam crest is wide to take into account construction demand but should not be too big, preferably 2~4m；
The length and bank crest level of the sand prevention bank set before described intake gate, should meet the maximum hair introduced needed for power station
The magnitude of current and the requirement of bank flow velocity is crossed, cross bank flow velocity by not causing that river bed load sediment median particle diameter starts control, cross bank stream
Speed is generally 0.6~1.8m/s；Dry season riverbed ecological flow should also be met to release demand, its elevation should be higher than that dry season riverbed
The water level of the natural river course corresponding to the ecological flow of demand, sand prevention bank is highly preferably 1~2m.
Described arrangement, it is adaptable on fully-loaded stream, scale be medium and small Hydraulic and Hydro-Power Engineering.Especially fit
For the facility arrangement of fragile, very high to the environmental protection requirement Hydraulic and Hydro-Power Engineering of affiliated area surroundings.
The present invention had both met generating water diversion and sand control requirement；The demand of ecological flow and fish migration can be taken into account again；It is not required to set
Put special fish pass and ecology is released facility, reduce quantities；River is not blocked, the influence to environment is reduced as far as possible, while
Also simplify intake gate gate traffic control, the difficulty of control.
It is described in detail with reference to specific embodiment：
Certain medium hydropower station engineering, Project Areas vulnerable environment, affiliated basin is fully-loaded stream, and head pivot area riverbed is right
Bank side is protection zone.According to environmental requirement, must not build for engineering influences right bank protection zone environment；Engineering needs to ensure former after building
The normal migration passage of raw fish；River course domestic demand is released ecological flow at least 4.37m3/s。
Engineering affiliated river flood season and dry season carry out water and differ larger, to ensure normal power generation diversion and the effect in power station
Benefit, need to stop up intake gate water level before gates high；But for take into account dry season release ecological flow and fish normal migration and need not be again
Special facility being respectively provided with, therefore, river should not all be blocked.Scale, development task demand and environmental protection according to engineering
It is required that, to ensure power station normal power generation diversion and benefit, while considering to reduce the influence to environment as far as possible, arranged in riverbed
Blocking dam being highly only 4m, not blocking river all.To avoid building for power station from influenceing right bank protection zone, generating diversion
Building is arranged in left bank.
Requirement, the engineering that the scale of incorporation engineering, consideration diversion and power are released to water level, sand discharge and ecological flow are to right bank
The factor such as the influence of protection zone and fish species, carry out comprehensive analysis determine this engineering can meet water diversion engineering generating
Major function requirement, can take into account again environmental protection and sand discharge demand generating water diverting structure arrangement.
As shown in figures 1-4, blocking dam 1 is arranged in riverbed, plays a part of banked-up water level, meet power station diversion
The requirement of generating.But the heap soil or fertilizer over and around the roots height of water level necessarily causes the decline of flow rate of water flow in river course, also necessarily causes lower sluicing stream to take husky energy
The decline of power, such as takes no action to necessarily cause the alluvial of silt in storehouse, so as to influence the generating diversion quality in power station and normal
On-road efficiency；Simultaneously because this engineering reservoir is substantially without storage capacity, the depth of water is shallower in storehouse, before the intake gate lock of power station inlet velocity compared with
Greatly, when intake gate opens a sluice gate diversion, the silt of greater particle size in river bed load is easily made to carry in channel, so as to cause to generate electricity
Diversion silt content increases and the Sediment Siltation in flume channel.Such as routinely mentality of designing, it is considered to power station diversion and power demand,
River should be blocked disconnected by blocking dam 1, still there is the demand of fish migration and ecological flow of releasing due to this engineering, such as all cut river course
It is disconnected, then the specialized facilities that fish pass and ecological flow are released must be set in addition, so then building species it is more, from now on power station adjust
Degree operation is complicated, periphery protection zone ambient influnence is increased and construction investment is larger.Through analysis and research, to simplify structure and work
Cheng Yunhang difficulty, and the influence to environment is reduced as far as possible, take following aggregate measures and solve：
1st, by blocking dam 1 and power station intake gate 3 close proximity to arrangement, to cause not dropped into the flow rate of water flow in storehouse as far as possible
It is low excessive, it is considered to the influence of the factor such as orographic condition, stream gradient, determine blocking dam 1 with power station intake gate 3 at a distance of about 80m.
2nd, for the benefit of silt discharge in storehouse, in the maximum scope of the position choice arrangement of blocking dam 1 gradient in the river course, should
Section mean inclination is about 1%, more than bed load sediment median particle diameter critical grade 4 ‰.
3rd, consider project scale, earial drainage to the washing away of downstream, to factors, the dam body dam of blocking dam 1 such as the influence degrees of environment
Crest level is no more than main stem elevation.If the height of blocking dam 1 obtains larger, although beneficial to the matter for improving power station generating diversion
Amount, but the increasing of its caused depth rise, the depth of water, will cause that flow rate of water flow lowers row that is more and being unfavorable for silt in storehouse in storehouse
Go out, thus blocking dam 1 height set it is smaller.Consideration carrys out in beach volleyball outbound major part, water level needed for analysis generating diversion
And flow rate of water flow is more than water level requirement needed for bed load sediment median particle diameter start velocity in storehouse, through comprehensive analysis, the dam of blocking dam 1
Body maximum height is defined as 4m.
4th, the demand of fish migration etc. is considered, river is not blocked disconnected all for blocking dam 1, and blocking dam is in the left and right bank two in river course
Side is arranged, in the main flow position future insufficiency 2 in river course, as the passage of fish pass, ecological flow, silt conveying etc..
5th, body according to this engineering fish is long, Burden-Swimming Ability of KM, migration characteristic the features such as, while mud when taking into account non-flood period water
Husky start velocity needs and should meet dry season to release the requirement of ecological flow, determines the width of breach 2.Breach primary section is
Trapezoidal, bottom width is 2.0m, and two side slope ratios are 1:1, the depth of water is 0.6~4.1m, indentation, there max-flow in migration season breach
Speed is about 1.2m/s, and breach is 5.2m to maximum bottom width along river.The sectional dimension of indentation, there, meets wanting for the normal migration of fish
Ask；Meanwhile, when dry season, natural water amount was smaller, Water Requirement passes through breach 2 to be essentially identical to the state in former river course
Under let out, when flood season natural water amount is larger, Water Requirement is let out under being combined by breach 2 and blocking dam both sides elevations dam body 1.
6th, it is highly relatively low due to blocking dam 1, come under husky dam body and breach 2 by blocking dam 1 to let out in river.Dry season
Runoff and sediment load amount hour, can by being let out under breach 2, flood season runoff and sediment load amount it is larger when, under being combined by dam body and breach 2
Let out.Dam body by can free overflow build is set, it is considered to dam stabilization and spend being connected for dam current and downstream, its section is upper and lower
Trip has been arranged as one and has answered the gradient, is taken as 1:0.4.Dam crest is wide to take into account construction demand but should not be too big, and this engineering is taken as 2m.
7th, the dash and the length and bank crest level of sand prevention bank 4 for being set before intake gate 3, introducing needed for should meeting power station is most
Big generating flow and the requirement of bank flow velocity is crossed, cross bank flow velocity by not causing that river bed load sediment median particle diameter starts control, root
According to river course inlet flow rate and sediment charge, particle composition situation, it is 0.6~1.8m/s to cross bank flow rates；
The length and bank crest level of dash and sand prevention bank 4, should also meet dry season riverbed ecological flow and release demand, and it is high
Journey should be higher than that the water level of the natural river course corresponding to the ecological flow of dry season riverbed demand.According to environmental requirement, engineering need to let out
Put ecological flow and at least should be 4.37m3/ s, according to the natural stage-discharge relation line in river course, river course naturally carrys out flow for 4.37m3/s
When, corresponding water level is 2157.14m, as ensures ecological flow Minimum requirements, and water-blocking bank elevation should be higher than that before intake gate
2157.14m.The fraction of the ecological flow let out under consideration, water-blocking bank elevation is 2157.50m before determining power station intake gate, and bank is high
It is 1m to spend, and length is 40m.So ensure that when natural water amount is less than 4.37m in river course3During/s, manual dispatching is not required to
Control, all natural water can not enter in the intake gate of power station and fully enter former river course.The setting of water-blocking bank both gave
Ecological flow is released the absolute guarantee of demand, in turn simplify frequent scheduling and the operation difficulty of intake gate gate.Due to not again
Set special ecological flow to release facility, save construction investment, also reduce the influence to environment.
