Description
Technical field
The invention belongs to hydraulic engineering drainage pumping stations technical fields, and in particular to a kind of raising Urban Waterlogging pumping plant side unit
The method of Inlet flow pattern.
Background technique
Due to unordered exploitation, it is serious to enclose tideland for cultivation phenomenon, and silt such as constantly deposits at the factors in addition, the Reservoir in part coastal cities
Hold and constantly reduce, capacity of flood storage substantially reduces；Meanwhile reservoir was drained off floodwaters also naturally vulnerable to off-lying sea tidal lockup, effective aerial drainage time
Limited, flood easily occurs for reservoir neighboring area.As the drainage pumping stations for effectively improving flood discharge flow, can solve coastal
The problems such as city reservoir capacity deficiency and neighboring area are drained flooded fields.But due to being limited by urban land anxiety, pumping plant occupied area
It is less than normal, fabric structure is compacter so that Forebay of Pumping Station import shrink suddenly, in addition often there is bias current in mainstream incoming flow, be easy
It causes Forebay of Pumping Station import two sides to flow back, causes pumping plant side unit Inlet flow pattern bad and seriously affect its safety run
Stability.
Summary of the invention
The purpose of the present invention is in view of the above-mentioned problems, proposing a kind of side for improving Urban Waterlogging pumping plant side unit Inlet flow pattern
Method.
To achieve the purpose of the present invention, it adopts the following technical scheme that
A method of Urban Waterlogging pumping plant side unit Inlet flow pattern is improved, is arranged before the intake pool of pumping plant two sides unit
Combined type rectifies measure, and the combined type rectification measure is made of diversion pier, baffle pier and crossbeam, and the pumping plant import is
Joining section, the import of joining section communicates with extraneous waters, exports and is connected with Forebay of Pumping Station, and joining section is arc-shaped along main flow direction
Contraction section, to play preferable drainage effect, the exit width of joining section is B, and entrance width is W and meets W=(1.2 ~ 2) B,
The inlet and outlet larger construction cost that will cause of width difference dramatically increases, and Forebay of Pumping Station length is L, width is to go out mouth width with joining section
It is equal to spend B, it is H that Forebay of Pumping Station, which runs the depth of water, has a slope before pumping plant intake pool, diffusion homogenization can be played to influent stream, tiltedly
Slope top of the slope and forebay import distance C=(0 ~ 0.2) L can make its diffusion homogenization insufficient apart from too far, slope angle β=10 ° ~ 15 °,
Slope angle is too small to make that Forebay of Pumping Station size is too long, slope angle is excessive easily causes flow separation, and pumping plant intake pool width is D, pumping plant
Two sides machine set isolation pier width B1=(0.15 ~ 0.2) D, width is too narrow, and structural strength is insufficient, width will affect greatly very much overcurrent
Sectional area；
Quantity N1=2 of the diversion pier, before being located at pumping plant two sides machine set isolation pier, diversion pier input end and tiltedly
Slope bench crest is concordant and carries out cavetto to reduce water impact loss, and outlet end is connected with pumping plant side machine set isolation pier nose portion, leads
Flow length L1=(0.6 ~ 0.9) L of pier, the applicant, which researchs and analyses, proves that the too short rectified action of length of diversion pier is not significant, too
Long then its improvement does not dramatically increase while can additionally increase cost of manufacture and occupies volume, width B2 and side unit
Separation pier width B1 is equal, the top of diversion pier and water surface distance H1=(0.05 ~ 0.1) H, and distance is too small to be easy to expose the water surface
And it influences pumping plant surrounding landscape, its rectified action can be made to be decreased obviously apart from too big；
Quantity N2=2 of the baffle pier, are located on the center line of two sides unit, the length L2=(0.4 of baffle pier
~ 0.5) L, length is too short to will affect its rectification effect, the too long cost of manufacture that will cause obviously increases, the input end of baffle pier with lead
Flow input end distance L3=(0.4 ~ 0.5) L of pier, the applicant researchs and analyses that proof distance is too close or too far to be all unfavorable for its whole
Stream, width B3=(0.05 ~ 0.1) D of baffle pier, width is too narrow, which to be difficult to ensure that its structural strength, width are too wide, can reduce flow-passing surface
Product, the both ends cavetto of baffle pier are flushed at the top of the top of baffle pier and diversion pier with reducing hydraulic loss；
Quantity N3=2 ~ 4 of the crossbeam, are vertically evenly arranged, crossbeam quantity easily cause too much larger hydraulic loss,
Quantity is then unfavorable for adjusting water flow very little, and beam width B4=(0.05 ~ 0.1) D, crossbeam is too wide to will increase cost of manufacture, too narrow appearance
Easily cause its structural strength insufficient, beam height H2=(0.1 ~ 0.15) H, beam height it is too small it is bad to the rectification effect of water flow,
Excessive to will cause overflow section deficiency, adjacent two crossbeams spacing H3=(0.05 ~ 0.12) H will affect combination beam away from excessive between the two
Rectification effect, flush at the top of the top of top side crossbeam and baffle pier, crossbeam and baffle pier input end distance L4=(0.1
~ 0.2) L is unfavorable for adjusting water flow apart from too far；
