Technical field
The present invention relates to the structure that a kind of utilization tributary built fish and Ecology passage, belong to fish protection technical field.
Background technology
Dam and sluice-gate engineering is built, and natural river is blocked in various degree, has blocked the migration of fish, cause the population quantity of migration fishes to decline to a great extent.For protection migration fishes; various countries are while dam and burrock is built; according to the characteristics of engineering and the demand of fish protection has built various types of fish pass structures, such as fish pass, imitative nature passage, transporting something containerized fish system, fish lift and fish lock are up with the river property migrant that helps to trace back.
It is applied to weir more fish pass, and often needs to be combined with dam, it is larger on work arrangement influence, and also the part dam type such as arch dam can not then lay because of the factor such as flood discharge safety or both sides landform.High dam needs to build considerably long fish pass come gradient of dissolving, cross the effect of fish it is difficult to ensure that.
Fish lock, fish lift, transporting something containerized fish system are only transported through to fish, and the aquatic ecosystem of dam site upstream and downstream is actually still blocked.Wherein fish lock, fish lift are equally existed the problem of dam is combined.Transporting something containerized fish system is then due to being related to the auxiliary of the professional facilities such as boat for collection and transportation of fish, and the manufacture of these facilities and operation have certain limitation, and is valley river course for downstream, and due to the reason such as current are anxious, river surface is narrow, fish gathering operation is difficult to implement.It can be seen that, effective fish, and the connection of aquatic ecosystem is to face global problem at present excessively how is realized between high dam reservoir upstream and downstream.
The content of the invention
It is an object of the invention to; the structure that a kind of utilization tributary built fish and Ecology passage is provided; with the demand for meeting fish migration and connecting upstream and downstream aquatic ecosystem; played a positive role to coordinate the contradiction between Hydraulic and Hydro-Power Engineering and ecological environmental protection, so as to overcome the deficiencies in the prior art.
The technical proposal of the invention is realized in this way：
A kind of utilization tributary of the present invention built fish and the structure of Ecology passage is, the structure includes downstream tributary is distributed with reservoir area and the downstream river course separated through dam, downstream river course；It is communicated between reservoir area or the reservoir area tributary and downstream tributary of reservoir area.
Foregoing utilization tributary was built in the structure of fish and Ecology passage, was communicated between the reservoir area and downstream tributary through communication channel connection.
Foregoing utilization tributary was built in the structure of fish and Ecology passage, was communicated between the reservoir area tributary and downstream tributary through communication channel connection.
Foregoing utilization tributary was built in the structure of fish and Ecology passage, and the communication channel is artificial fish pass, imitative nature river course or open channel form.
Foregoing utilization tributary was built in the structure of fish and Ecology passage, and one end that the communication channel is connected with reservoir area is provided with collection attracting system.
Foregoing utilization tributary was built in the structure of fish and Ecology passage, and the downstream tributary or reservoir area tributary are respectively positioned near dam, and the tributary flow in downstream tributary or reservoir area tributary is more than 1m3/s.
Foregoing utilization tributary was built in the structure of fish and Ecology passage, and the communication channel, which is located at downstream tributary one end and is less than, is located at reservoir area or reservoir area tributary one end, and the gradient of communication channel is between 0.5 ‰~3%.
With the above mentioned technical proposal, compared with prior art, the present invention built fish and Ecology passage to the present invention using tributary, and water conservancy and hydropower multi-purpose project is not influenceed, and the requirement that fish upstream and downstream is exchanged can be met, be particularly suitable for use in high water head Hydraulic and Hydro-Power Engineering.Influence for reduction water power hydraulic engineering to fish migration, promoting the ecological protection in river has positive effect.

Embodiment
The present invention is described in further detail with reference to the accompanying drawings and examples, but not as any limitation of the invention.
A kind of utilization tributary of the present invention built the structure of fish and Ecology passage, as illustrated in fig. 1 and 2, including the reservoir area 1 separated through dam 2 and downstream river course 3, and downstream tributary 4 is distributed with downstream river course 3；6 are communicated between reservoir area 1 or reservoir area tributary 5 and downstream tributary 4.Connected between reservoir area 1 and downstream tributary 4 through communication channel 6.6 are communicated between reservoir area tributary 5 and downstream tributary 4.Communication channel 6 is artificial fish pass, imitative nature river course or open channel form.One end that communication channel 6 is connected with reservoir area 1 is provided with collection attracting system 7.Downstream tributary 4 and reservoir area tributary 5 are respectively positioned near dam 2, and tributary flow is relatively stable and more than 1m3/s.Communication channel 6, which is located at the one end of downstream tributary 4 and is less than, is located at reservoir area 1 or the one end of reservoir area tributary 5, and the gradient of communication channel 6 is between 0.5 ‰~3%.
The invention mainly comprises tributary, communication channel 6 and collection attracting system 7；Tributary includes downstream tributary 4 and reservoir area tributary 5, downstream tributary 4 or reservoir area tributary 5 are close near dam 2, under normal conditions, ultimate range between downstream tributary 4 or reservoir area tributary 5 and dam 2 is no more than 5 kilometers, the tributary flow in downstream tributary 4 or reservoir area tributary 5 is relatively stable and more than 1m3/s, the initiating terminal of communication channel 6 is located at drop of the section of downstream tributary 4 without larger drop, and the fish composition in downstream tributary 4 is as similar with the fish composition in downstream river course 3 as possible.Due to the remittance of the flow of downstream tributary 4, there is good inducing action to downstream fish, quite a few fish can trace back along downstream tributary 4.The initiating terminal of communication channel 6 is located on downstream tributary 4, and terminal section is located at reservoir area 1 or reservoir area tributary 5, and destination terminal elevation is higher than initiating terminal elevation, and the gradient of communication channel 6 is no more than 3%, typically between 0.5 ‰ to 3%.The terminal of communication channel 6 section can be located at reservoir area or storehouse tail above flowing water section, can also be located on reservoir area tributary 5.Communication channel 6 can be using diversified forms such as open channel, fish pass, and such as gradient is larger, need to consider energy dissipation measure.If the terminal section of communication channel 6 is located at reservoir area 1, the luffing of reservoir operating level need to be considered, using layering import or the multiple imports of construction, and using collection attracting system 7.
