Abstract
The utility model relates to a spillway tunnel structure, which is capable of improving operational flexibility while normal flood discharging is guaranteed and reducing influences of gate vibration resolving operations on comprehensive using efficiency of reservoirs. The technical scheme includes that the spillway tunnel structure comprises a spillway tunnel and a lock chamber connected to the tail of a gradient section of a spillway tunnel outlet, and two arc-shaped gates are mounted in the lock chamber. The spillway tunnel structure is characterized in that a middle mound is arranged from the tail of the gradient section of the spillway tunnel outlet to an outlet of the lock chamber, the two arc-shaped gates are arranged between each side of the middle mound and the corresponding side wall of the lock chamber respectively, and a gate groove is arranged corresponding to the motion trail of each arc-shaped gate. The spillway tunnel structure is applicable to structural improvement of single-hole spillway tunnels of small and medium water conservancy and hydropower engineering with earth and rockfill dam or in densely populated downstream areas such as towns and the like.
Description
Technical field
The utility model relates to a kind of flood-discharge tunnel structure.Be applicable to that dam type is that earth and rockfill dam or downstream are the structure of improving the single hole flood discharging tunnel in the middle-size and small-size Hydraulic and Hydro-Power Engineering of personnel compact districts such as cities and towns.
Background technology
In middle-size and small-size Hydraulic and Hydro-Power Engineering, generally adopt the single hole flood discharge at flood discharge hole outlet at present, structural shape is simpler.If reservoir dam be earth and rockfill dam or reservoir from cities and towns etc. the personnel compact district nearer; But upper reaches incoming flow is generally less; Will occur because of the designed standard for flood control height causes the flood discharge hole outlet section bigger, the Segment gate build is bigger, makes Segment gate in frequent little aperture unlatching in flood season; Increased the risk of gate vibration, operation brings certain difficulty to headstock gear.The dumb comprehensive utilization to normal flood discharge and reservoir of operation all brings certain influence.
Summary of the invention
The technical problem that the utility model will solve is: according to the problem of above-mentioned existence, a kind of flood-discharge tunnel structure is provided, under the prerequisite that guarantees normal flood discharge, increases the flexibility of operation, reduce the efficient because of the operating influence reservoir comprehensive utilization that solves the gate vibration.
The technical scheme that the utility model adopted is: the flood-discharge tunnel structure; Comprise flood-discharge tunnel and be connected to the last lock chamber of flood-discharge tunnel outlet transition section; Segment gate is housed in the lock chamber, it is characterized in that: the exit at flood-discharge tunnel outlet transition section end to lock chamber is provided with pier in, and said Segment gate has two; Be arranged between Zhong Dun both sides and the lock chamber sidewall, gate slot be set corresponding to the movement locus of Segment gate.
The crest level of pier is identical with the maintenance elevation of lock chamber in described.
Pier is arranged on the axis of lock floor in described.
The The initial segment of pier is symmetrical circular arc pyramidal structure in said, and the terminal point section is both sides chamfering cavetto structures.
The beneficial effect of the utility model is: the flood-discharge tunnel outlet changes diplopore into the single hole structure that is provided with floodgate of middle pier.Hour only need to open the preparatory flood discharge water of a fan arc door, control discharge at incoming flow.Bigger like incoming flow, then open another fan arc door in succession.The aperture of arc door and arc door drop into quantity and control according to operational procedure according to the incoming flow situation.Because of the cross dimensions reason, the big arc gate opening of opening ratio single hole of little arc door wants big under same flow condition, has reduced the risk of vibration and cavitation corrosion etc.As adopting the single hole structure, big arc door often solves through increasing aperture for solving the possible vibration problem of the little aperture of arc door, so just possibly influence the reservoir comprehensive utilization ratio.The arc door of above-mentioned one-to-two is arranged the flexibility that can under the prerequisite that guarantees normal flood discharge, increase operation, improves the efficient of reservoir comprehensive utilization.

The specific embodiment
Present embodiment is a kind of flood-discharge tunnel structure that middle pier is set in flood-discharge tunnel; Mainly comprise flood-discharge tunnel 1, lock chamber 3 and Segment gate 4; Wherein lock chamber is connected to flood-discharge tunnel outlet transition section 1-1 end; Segment gate places in the lock chamber, and the position, lock floor 3-1 axis of said lock chamber is provided with middle pier 2, changes flood discharging tunnel single hole structure into double-pore structure; Segment gate is arranged between Zhong Dun both sides and the lock chamber sidewall, in Zhong Dun both sides and lock chamber sidewall gate slot 5 is set corresponding to the movement locus of Segment gate.
Middle pier is begun by flood-discharge tunnel outlet transition section latter end, and till lock floor outlet 3-2 place, its crest level is identical with lock chamber maintenance elevation; Middle pier The initial segment is symmetrical circular arc pyramidal structure, and the terminal point section is both sides chamfering cavetto structures.Pier can be used as the braced structures of arc door trunnion beam and lock chamber in described, strengthens big width lock chamber export structure stability.
This structure can be according to designing requirements such as flood discharge hole outlet flood discharge, energy dissipatings, and the plane structure pattern of centering pier is adjusted.
