Abstract
One kind is suitable for medium and small reservoirs conveyance tunnel and rolls over the cantilever bar gate type makeup of the imports, in dam upstream batter end, sets a rectangle intake pool, and in its vertical dam top direction, headstock gear is set with dam crest isometry position, cantilever gate opening is rolled over by controlling, controls conveyance tunnel flow.
Description
Technical field
The present invention relates to a kind of water inlet structures suitable for medium and small reservoirs conveyance tunnel import.
Background technology
At present, the import form of medium and small reservoirs conveyance tunnel is essentially tower conveyance tunnel import, climbing hole conveyance tunnel import
And oblique pull lock import, tower conveyance tunnel import, tower conveyance tunnel import need to set work tower and service bridge, tower top sets headstock gear
Carry out the keying operation of gate；Climbing hole conveyance tunnel import need to meet water according to landform and Dam Designs in Last situation along bank slope or dam
Slope sets multistage water inlet, and import sets cover board or stopper, and way to manage is to be classified to open water inlet according to reservoir level situation.This
The import form of two kinds of conveyance tunnels, cost is high, and long construction period, complex process is inconvenient, and construction management and later maintenance are stranded
It is difficult.
The content of the invention
In order to overcome the shortcomings of in existing conventional conveyance tunnel import form design, the present invention provides a kind of new water delivery
Hole import form, the form are not only simple in structure, and with cheap, easy construction, operation and final management and maintenance simplicity etc.
Advantage.
The technical solution adopted by the present invention to solve the technical problems is：In dam upstream batter end, a rectangle is set
Intake pool, and in its vertical dam top direction, headstock gear is set with dam crest isometry position.Intaking pool size can base area
Shape, water level and the adjustment of barrel flow.Two gate holes and manhole are reserved in intake pool top, and folding cantilever gate seat is on lock hole
Being connected by steel hawser with dam crest headstock gear relies on gate dead weight and headstock gear to realize the keying function of gate, lock hole, lock
Door size and gate opening are depending on the hydrologic regime of concrete engineering.
The invention has the advantages that it can simplify facility structure while management conveyance tunnel operation is realized, reduce into
This, easy construction, later stage structural repair facilitates, easy to utilize.

Specific embodiment
In dam upstream batter end, a rectangle intake pool is set（5）, and in its vertical dam top（11）Direction, with
Dam crest isometry position sets headstock gear（10）；Intake pool（5）Top is to reserve two lock holes（4）And manhole（12）, installation
Roll over cantilever gate（3）；Roll over cantilever gate（3）Pass through hawser processed（2）With dam crest headstock gear（1）Connection is conducted oneself with dignity and is opened by gate
Machine is closed to realize the keying function of folding cantilever gate, control current enter intake pool（5）After flow into conveyance tunnel（6）, gate maximum
Open degree is by gate limiting block（14）Limitation.
Claims (1)
1. a kind of folding cantilever bar gate type makeup of the imports suitable for medium and small reservoirs conveyance tunnel, it is characterized in that：In dam upstream batter
End sets a rectangle intake pool, and in its vertical dam top direction, headstock gear is set with dam crest isometry position；Into
Pond top is to reserve two lock holes and manhole, and the installation folding cantilever gate on lock hole；Folding cantilever gate passes through hawser processed
It is connected with dam crest headstock gear, by gate dead weight and headstock gear to realize the keying function of folding cantilever gate, control current enter
Conveyance tunnel is flowed into after intake pool, gate maximum open degree is limited by gate limiting block.
