Description

The up fish structure excessively that under a kind of reservoir dam, tributary is combined with mainstream on dam
Technical field
This utility model belongs to Hydraulic and Hydro-Power Engineering environmental protection technical field, is specifically related to tributary under a kind of reservoir dam The up fish structure excessively being combined with mainstream on dam.
Background technology
The dam site upstream and downstream Fish communication channel that water resources and hydropower development is related to intercepts and fish gene communicating questions are It is built and runs environmental problem main and the most in the urgent need to address, for this reason, competent administrative department for environmental protection is general all The protection Fish and the degree of susceptibility situation that are related to for water resources and hydropower development are it is proposed that dam site upstream and downstream fish pass structure is built If, run and correlational study requirement, such as fish pass, imitative nature passage, the mistake of fish lock, transporting something containerized fish system or various combination mode Facilities for fish's passage etc., to the Sustainable Healthy Development of feasible region, river basin ecological environment.
The topographic and geologic condition limited because being limited to Hydraulic and Hydro-Power Engineering reservoir upstream and downstream fish pass structure arrangement, and reservoir Planning or existing main structures arrange that the extremely limited fish pass structure that general layout causes builds site condition.At present, on reservoir Downstream fish pass structure is newly-built, transformation technical difficulty is generally larger, cost is generally higher, operability is generally poor, especially It has the side such as the construction coordination between main structures and newly-built fish pass structure, safety in operation in existing reservoir upstream and downstream Even more there is many restrictions in face.
In order to solve the problems, such as well Hydraulic and Hydro-Power Engineering mining under reservoir to upstream up cross fish, fish pass structure is implemented Impetus be transferred to orographic condition tributary advantageously downstream in itself from reservoir, under a kind of reservoir dam of necessary offer Tributary be combined with mainstream on dam up cross fish structure, make full use of that tributary under reservoir dam is good to cross fish condition, and to lower of dam Flow and after existing barrage structures are removed, arrange imitative nature passage, so that dam downstream Fish is passed through " under mainstream dam under dam Cross fish tributary (the existing barrage structures containing intending dismounting) dam and descended mainstream on mainstream segment dam on fish Zhi Liuzhi dam " Up fishing line road excessively, to realize the up environmental requirement crossing fish of reservoir upstream and downstream.
Utility model content
For solving the above problems, this utility model provides the up mistake that under a kind of reservoir dam, tributary is combined with mainstream on dam Fish structure.Thus solve the planning of reservoir upstream and downstream or existing main structures with the technology operability planning to build fish pass structure, Cost economic, construction coordination, the restricted problem of safety in operation
This utility model is achieved by following technical solution.
The up fish structure excessively that under a kind of reservoir dam, tributary is combined with mainstream on dam, including reservoir dam and and reservoir dam Mainstream under mainstream and dam on connected dam, mainstream under described dam is disposed with tributary under dam, mainstream on dam is disposed with dam Stream, described reservoir dam downstream is provided with reservoir dam and descended fish tributary, and is provided with barrage on mistake fish tributary under reservoir dam Structures.
The mouth that enters to converge in described dam Xia Guoyu tributary is connected with mainstream under the dam on reservoir dam, dam Xia Guoyu tributary go out converge Mouth descended mainstream segment on fish Zhi Liuzhi dam to be connected with mainstream on dam by dam.
Described dam descended mainstream segment on fish Zhi Liuzhi dam to be disposed with the pool fish pass of culvert or aerial construction, and in pond It is provided with inducing installation on formula fish pass.
