Description
Technical field
Fish system is crossed the utility model is related to a kind of, fish system is crossed more particularly, to a kind of cut-off dam hydraulic engineering,
Belong to hydraulic and hydroelectric engineering Building Design building technology field.
Background technology
Fish pass is the channel for fish migration.It is described with popular language, certain fish, which have from lower reaches of river, to be migrated to river
The habit of upstream oviposition is flowed, after river has blocked river since artificial origin has such as built checkdam, fish are upstream whirled
The channel of trip will be destroyed.In order to protect the habit of fish, need to pass through dam and build artifical flume as fish migration
Channel, i.e. referred to as fish pass.Flow enters fish pass from upstream, flows out fish pass from downstream, but fish are from downstream into fish pass, from upper
Fish pass is swum out of, thus fish pass upstream intake is referred to as fishway exit, and fish pass downstream water outlet is fish pass import.
In order to realize that fish pass crosses the purpose of fish, fish pass usually requires to meet claimed below：First, depth of water requirement, fish pass domestic demand
Keep 1.0~1.5m depth of waters；2nd, slope requirement, in order to enable fish along flow upstream migration, flow rate of water flow in fish pass
It is less than the speed of fish migration, this requires fish pass needs to keep a gradient that is relatively slow and stablizing；3rd, when upstream water level becomes
During change, fishway exit needs the measure that can adapt to SEA LEVEL VARIATION, it is ensured that keep 1.0 under various water levels, in fish pass for a long time~
1.5m the depth of water.
In order to meet above-mentioned requirements, at present frequently with following two fishway exit arrangements in engineering：
1 existing program one
Fishway exit is arranged in checkdam upstream by the program, and sets multiple fishes simultaneously along elevation in eulittoral zone
Road exports, and each outlet is controlled using 1 bulkhgead gate.The characteristics of structure, is：1st, fishway exit is arranged
In checkdam upstream；2nd, in upstream water level luffing area, fish pass is along the multiple outlets of elevation arrangement, and each fishway exit is on elevation
It is mutually linked；3rd, each fishway exit arranges the lower stream that sluices of 1 plate steel gate control.The major advantage of the structure is：
In upstream water level luffing area, each elevation section is arranged with fishway exit, when upstream water level is located at a certain elevation, only needs to open
The gate of corresponding elevation fishway exit, and close the gate of other fishway exits, you can meet 1.0~1.5m depth of waters in fish pass
It is required that.The major defect of the structure is：1st, fishway exit is arranged in upstream, longer to length along river, corresponding excavated volume
Or concrete works amount is larger, fish pass construction investment is larger；2nd, fishway exit quantity is more, and needs the feelings according to upstream water level
Condition carries out each gate opening and closing in time, when upstream water level amplitude of fluctuation is larger, changes more frequent, fishway exit gate
Operation control is also relatively complicated.
2 existing programs two
Fishway exit is combined arrangement with checkdam by the program, and is set gradually along the water blocking axis of dam in eulittoral zone more
A fishway exit controls each fishway exit using 1 bulkhgead gate.The advantages of structure, is：1st, by fishway exit with
Checkdam combines arrangement, and each fishway exit horizontal direction upper edge water blocking axis of dam arranges successively, and elevation is mutually linked on direction, phase
Adjacent fishway exit is connected by the linking channel in downstream, and lowest elevation fishway exit is connected by being connected channel with fish pass import；
2nd, for single fishway exit, upper middle part is provided with 1 plate work gate opening/closing, downstream setting linking channel and next stage fish
Road outlet connects.The major defect of the structure is：1st, the requirement for adaptation range of stage, upstream need to set along the axis of dam more
A fishway exit, it is impossible to suitable for the checkdam of Narrow Valleys；2nd, since each fishway exit is both needed to 1 plate work lock of setting
Door, and need, according to the situation of upstream water level, to carry out each gate opening and closing in time, when upstream water level amplitude of fluctuation is larger,
When changing more frequent, the operation control of fishway exit gate is also relatively complicated.
