Embodiment
It is a kind of excavation work that can effectively reduce construction of hydropower plant provided by the utility model as shown in Figure 1 and Figure 2
Journey, reduce the compound water flowing out structure for Hydraulic and Hydro-Power Engineering of up-front investment cost.Described compound water flowing out structure includes leading
Water discharge tunnel 1 is flowed, described compound water flowing out structure also includes Tail water reuse system 2, the water side 3 of the Tail water reuse system 2
Connected with the drain measure tunnel 1 described in that part after power plant building.The application passes through going out Tail water reuse system 2
Water end (W.E.) connects with that a part of drain measure tunnel 1 after power plant building.So as to realize the water side 3 of Tail water reuse system 2
Common function, reaches the water outlet avoided as Tail water reuse system 2 with that a part of drain measure tunnel 1 after power plant building
The purpose that end 3 is individually excavated, supporting and lining cutting are basic, and then the foundation excavation amount of construction of hydropower plant can be largely reduced,
The up-front investment of engineering construction is reduced, the combination arrangement of diversion tunnel and tailwater channel is realized and purpose is used in combination.At the same time it can also
Make the land resource that whole engineering layout is compacter, occupancy is in short supply less.
In above-mentioned embodiment, for the ease of that a part of institute after described Tail water reuse system 2 and power plant building
Connection between the drain measure tunnel 1 stated, compound water flowing out structure described herein also include transition passage 4, the tail water
The water side 3 of exhaust system 2 passes through that after the power plant building of described transition passage and the 4 drain measure tunnels 1
Part connects.Generally all include the quantity a plurality of tail water suitable with generating set quantity in conjunction with described Tail water reuse system 2
The characteristics of discharging canal 5, the quantity for the transition passage 4 that the application is set is suitable with the quantity of the Tail water reuse canal 5, this
Sample, can be so that the water side of each Tail water reuse canal 5 passes through corresponding transition passage 4 and the drain measure respectively
That point of portion connection after the power plant building of tunnel 1.Meanwhile pouring in down a chimney in order to avoid tail water, generally by after power plant building
That part described in drain measure tunnel 1 bottom plate 6 elevation be positioned below the transition passage 4 water side bottom
The elevation of plane 7, and the baseplane 7 of the posterior segment of each Tail water reuse canal 5 is gradually risen along water (flow) direction elevation
It is high.
The characteristics of in conjunction with drain measure tunnel 1 and the entirely different service life of Tail water reuse system 2, i.e. drain measure
Tunnel 1 is typically used to the water above cofferdam exporting to downstream in the process of construction of engineering, and Tail water reuse system 2 is in work
When being generated electricity after the completion of Cheng Jianshe, for discharging the tail water of generating set.Therefore, compound water flowing out structure described herein also includes
Later stage occluding body 8, the drain measure tunnel 1 described in that part before power plant building are existed by described later stage occluding body 8
Water conservancy diversion blocks after terminating.So, by the closure of later stage occluding body 8, can make described in that part after power plant building
Drain measure tunnel 1 forms one with transition passage 4 and Tail water reuse canal 5 and completely applies structure, ensures the unobstructed of draining.Enter
One step, according to the layout feature of the various buildings of engineering site, the longitudinal center line of Tail water reuse canal 5 and generating described in each bar
The angle of the longitudinal center line of that a part of drain measure tunnel 1 after factory building is between 85 °~95 °.Certainly, if
It can also be any other number of degrees between 0~180 ° to need described angle, and it arranges that quantities is most according to so that scene is convenient
It is defined less.
In summary, after using the compound water flowing out structure of the application offer, when building, the diversion tunnel can be faced
When building, tailwater channel is permanent building, to adapt to the needs of engineering construction；And when setting, the diversion tunnel tract
When being combined with tailwater channel, the structure design of bound fraction uses permanent building design standard；When in use, described diversion tunnel
In construction time excessively stream, the passage between factory building tailwater channel and diversion tunnel retains, and factory building tailwater channel is got through after diversion tunnel closure
Passage between diversion tunnel；Finally, after whole engineering construction completion, after the closure of described diversion tunnel, factory building tail water is direct
Diversion tunnel tract is discharged into, directly using letting out factory building generating water under existing diversion tunnel；Described factory building tailwater channel outlet compared with
Diversion tunnel tract is high so that tailwater channel outlet is less prone to Yong Shui phenomenons；And tailwater channel has certain distance, water away from underwater bed
Stream is smaller by downstream stage backwater effect, and flow-shape is more smooth；Described factory building tailwater channel exit flow rate of water flow is larger,
The diversion tunnel tract being mutually connected therewith is not easy shoal materials.
Above-mentioned compound water flowing out structure of the present utility model also has following beneficial effect to be：I.e. with generally meeting to lead respectively
Flow use the function of hole and tailwater channel, above hydraulic structure is provided separately, and quantities is larger, invest it is also big, the machinery that uses,
Place, artificial etc. also increase.Diversion tunnel and tailwater channel are combined arrangement, not only meet more than building in construction time, runtime
Different service requirements, the advantages of characteristics of compact layout, quantities are small, the duration is saved is also equipped with, is worth similar projects to be used for reference.
