Description
Technical field
The utility model belongs to hydraulic and hydroelectric engineering technical field, chokes water structure more particularly, to a kind of combination of labyrinth weir.
Background technique
Labyrinth weir is choked water structure and is generally made of inlet structure, water retaining structure, energy-disspating.Inducer is certain
The approach channel of length, approach channel water (flow) direction and labyrinth list palace centerline parallel, keep flow-shape before weir uniform；Building is choked water as fan
Palace weir, free overflow；Arranged downstream energy-disspating, prevents downstream river course from washing away.
Labyrinth type spillway is also known as labyrinth weir, is a kind of discharge structure of no lock control, and weir crest axis is in broken line type,
A palace is formed between two broken lines, each palace is respectively formed a Zheng Yan and two side weirs.Under conditions of overflow is of same size,
The overflow forward position length of labyrinth weir is longer than straight line weir, therefore its discharge capacity is bigger than linear weir, especially in low water head situation
Under, its discharge capacity is almost directly proportional to overflow forward position length.
Labyrinth weir is in the sharp-crested weir of broken line type arrangement in plane, by increasing effective weir crest length, to increase aerial drainage
Amount, flat shape have U-shapedIt is trapezoidalAnd triangleDeng.
If river all uses labyrinth weir, river palace is interior, upper river is easy to happen sediment siltation, and therefore, it is necessary to set
Set sand surfing structure.
Utility model content
