Abstract
The utility model provides a wall is led to bank formula spillway inlet channel, is including leading the wall body, has offered the water conservancy diversion hole on the wall leading, at downthehole vertical many the 1st diversion pier that install of water conservancy diversion, has set firmly the 2nd diversion pier mound on leading a tip of wall to the 2nd diversion pier's one end protrusion in the terminal surface of leading the wall, the utility model discloses can reduce bad water conservancy phenomenons such as leading wall vertical scroll swirl, make each hole influent stream of spillway overflow weir more balanced, increase the holistic ability of overflowing of spillway.
Description
Technical field
This utility model relates to Bank-run Spillway flood discharge technical field in Hydraulic and Hydro-Power Engineering, relates to a kind of Bank-run Spillway flume and leads wall.
Background technology
Owing to Bank-run Spillway is positioned at side, river course, the streamflow regime of inlet channel therein stablizes for spillway fluidised form and earial drainage plays an important role, and therein to lead the impact that inlet channel Inlet flow pattern can bring by wall the biggest.Existing wall of leading is usually employing splayed aileron, and owing to lower section does not has pod apertures, current can led wall side by block, and the most this wall of leading can not effectively reduce the unfavorable fluidised form such as horizontal mobility and vertical-axis eddy in inlet channel.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of Bank-run Spillway flume and leads wall, can alleviate bad hydraulic phenomenon such as leading wall vertical-axis eddy, make spillway downflow weir each hole influent stream more equalize, and increases the conveyance capacity that spillway is overall.
In order to solve above-mentioned technical problem, the technical solution of the utility model is: a kind of Bank-run Spillway flume leads wall, including leading wall body, pod apertures is offered on wall leading, vertically-mounted in pod apertures have many first diversion piers, the one end lead wall is installed with the second diversion pier, and one end of the second diversion pier protrudes from the end face leading wall.
Being shaped as of pod apertures is trapezoidal.
The cross sectional shape of the first diversion pier is oval, and major axis oval in each first diversion pier cross section is parallel to each other.
Major axis oval in first diversion pier cross section is less than or equal to 30 degree with the angle of water (flow) direction.
It is arc surface that second diversion pier bears the one side of water impact.
The beneficial effects of the utility model are: by the pod apertures leading on wall, a part can be made to impact the lateral current leading on wall and to first pass through pod apertures entrance inlet channel, and then balance leads the water-head of wall both sides effectively, lateral current flow around the second diversion pier is reduced, reduce the flow velocity of the water body moved around the second diversion pier simultaneously, alleviate the bad hydraulic phenomenon such as vertical-axis eddy and transverse flow speed, make spillway downflow weir each hole influent stream more equalize, increase the conveyance capacity that spillway is overall.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings this utility model is described further:
Fig. 1 is schematic front view of the present utility model,
Fig. 2 is the generalized section in Fig. 1 at A-A.
Detailed description of the invention
As depicted in figs. 1 and 2: a kind of Bank-run Spillway flume leads wall, including leading wall 1 body, pod apertures 3 is offered on wall 1 leading, vertically-mounted in pod apertures 3 have many first diversion piers 2, the one end leading wall 1 is installed with the second diversion pier 4, and one end of the second diversion pier 4 protrudes from the end face leading wall 1.
Being shaped as of pod apertures 3 is trapezoidal.
The cross sectional shape of the first diversion pier 2 is oval, and major axis oval in each first diversion pier 2 cross section is parallel to each other.
Major axis oval in first diversion pier 2 cross section is less than or equal to 30 degree with the angle of water (flow) direction, this structure so that in inlet channel water surface the tranquilest, reduce the bad hydraulic phenomenon such as whirlpool rolling growth and water level fluctuation in flume, made sluice stream more smooth out.
It is arc surface that second diversion pier 4 bears the one side of water impact.
As depicted in figs. 1 and 2: by leading the pod apertures 3 on wall 1, a part can be made to impact the lateral current led on wall 1 first pass through pod apertures 3 and enter inlet channel, and then balance leads the water-head of wall 1 both sides effectively, lateral current flow around the second diversion pier 4 is reduced, reduce the flow velocity of the water body moved around the second diversion pier 4 simultaneously, alleviate the bad hydraulic phenomenon such as vertical-axis eddy and transverse flow speed, make spillway downflow weir each hole influent stream more equalize, increase the conveyance capacity that spillway is overall.
