Abstract
The invention relates to a spiral-lifting water pool type fishway. The spiral-lifting water pool type fishway is simple in structure, convenient to construct and small in occupied place. According to the technical scheme, the spiral-lifting water pool type fishway is characterized in that an upward vertical annular column-type structure is constructed on the downstream side of a dam, the elevation of the annular column-type structure is equivalent to that of the top of the dam, the water pool type fishway is spirally arranged according to the calculated gradient along the periphery of the outer wall or the inner wall of the annular column-type structure, and the fishway is lifted to the upstream water level from the downstream water level step by step. The spiral-lifting water pool type fishway is applicable to a water conservancy project and particularly solves the problem of migration of aquatic organisms in medium-low waterhead dams.
Description
Technical field
The present invention relates to a kind of spiral pond formula fish pass.Be applicable to hydraulic engineering, the hydrobiological migration problem of low water head dam in especially solving.
Background technology
The development of China's hydropower, large quantities of middle low water head dams build up in succession, and Dam Construction has produced larger impact for aquatile, and particularly the obstruct for migration fishes affects.The hot topic that the fish pass layout of arising at the historic moment and structure design become research gradually.
The western high mountain gorge of China basin often has the characteristics such as the bank slope landform is precipitous, riverbed is narrow, utilize bank slope to arrange that engineering quantity and the difficulty of fish pass are all larger, and because drop is larger, be subject to the restriction of fish self Burden-Swimming Ability of KM, often the fish pass axis is longer, need to take in larger ，Ruo riverbed, place and adopt the plane side-by-side to arrange, need many row's fish pass just can meet the demands, have the shortcoming of hinge difficult arrangement.
Summary of the invention
The technical problem to be solved in the present invention is: for the problem of above-mentioned existence, provide a kind of simple in structure, easy construction, spiral pond formula fish pass that occupied ground is little.
The technical solution adopted in the present invention is: a kind of spiral pond formula fish pass, it is characterized in that: build annulated column formula structure straight up in the dam downstream, this annulated column formula structure elevation is suitable with crest elevation, press calculating gradient screw arrangement water tank type fish pass along annulated column formula structure outer wall or inwall surrounding, this fish pass rises to the upper pond level place step by step by the level of tail water.
Described water tank type fish pass is comprised of sidewall, base plate and dividing plate, the fish pass minimum structural requirement height of height >=fish pass that rear base plate rises that rotates a circle.
Described water tank type fish pass gradient i=2.5%.
Interval 1m between the sidewall top of described water tank type fish pass and the base plate of top fish pass.
Described annulated column structural section is square, circle or polygon.
The invention has the beneficial effects as follows: the present invention effectively utilizes the surrounding girth of annulated column structure and illumination condition to carry out the fish pass layout, the shape of annulated column structure, size can be adjusted according to actual conditions, also can adopt frame construction is support, there is structural configuration flexible, be easy to daylighting, floor space is little, and engineering quantity is less, and the dykes and dams larger to the height of water are particularly applicable.
The accompanying drawing explanation
The sectional side elevation that Fig. 1 is embodiment 1.
The A-A sectional view that Fig. 2 is Fig. 1.
The sectional side elevation that Fig. 3 is embodiment 2.
The B-B sectional view that Fig. 4 is Fig. 3.
The specific embodiment
Embodiment 1:
As shown in Figure 1 and Figure 2, the present embodiment is a kind of external spiral rising water tank type fish pass, builds in the dam downstream in this example of annulated column formula structure 1(and to adopt the solid post minor structure), this annulated column formula structure arranges straight up, its elevation is suitable with the dam top elevation.In the present embodiment, the cross section of annulated column formula structure 1 is rectangle, and along this annulated column formula structure outer wall, according to certain slope screw arrangement water tank type fish pass 2(, sidewall 201, base plate 202 and dividing plate 203, consists of), this fish pass rises to the upper pond level place step by step by the level of tail water.
Embodiment 2:
As shown in Figure 3, Figure 4, the present embodiment is a kind of inside spin rising water tank type fish pass, builds annulated column formula structure 1 in the dam downstream, and this annulated column formula structure arranges straight up, and its elevation is suitable with the dam top elevation.In the present embodiment, the cross section of annulated column formula structure 1 is rectangle, along this annulated column formula inner structural wall according to certain slope screw arrangement water tank type fish pass 2, this fish pass lower end is communicated with the level of tail water via the outlet pass of annulated column formula structure 1 lower end, and rises to step by step the upper pond level place.Keep certain spacing in this example between relative water tank type fish pass 2, form and be similar to hypaethral structure, be conducive to natural lighting.
For water tank type fish pass 2 gradients in known situation, only need to meet the fish pass minimum structural requirement height of height >=fish pass that rear base plate rises that rotates a circle, can meet arrangement requirement.
In above-described embodiment, the above and below the dam water surface is poor greatly is H=21, water tank type fish pass 2 gradient i=2.5%, water tank type fish pass sidewall height is 1.5m, fish pass base plate height 0.5m, illumination demand headroom 1m(is that between the base plate 202 of sidewall 201 tops and top fish pass, interval needs 1m), the minimum structural requirement height of fish pass △ h=1.5+1+0.5=3m, that is to say that the height >=3m that rotates a circle fish pass rear base plate rises can meet the demands, and needs the perimeter L ≈ △ h/ i=3/0.025=120m of annulated column formula structure.
The rectangular layout that adopts wide 10m * long 50m is example, and rectangular configuration perimeter L=10 * 2+50 * 2=120m meets spiralling structural requirement.The number of turns n=H/ △ h=21/3=7 that needs rotation, then adjust and can meet arrangement requirement according to the actual arrangement distance.Employing is similar to the arrangement form of cantilevered balcony in annulated column formula structure 1 inside and outside spiral, and the fish pass girth that rotates a circle is 120m, gradient i=2.5%, and the height of the lifting that rotates a circle is 3m, and water tank type fish channel structure height is 2m, and illumination headway is 1m.
