Description
Technical field
The present invention relates to a kind of anti-silting system of diversion, more particularly to a kind of anti-silting system of convex bank diversion.
Background technology
The water yield is reliable, water quality is good, and cost is rationally water intake engineering top priority to be solved, therefore, intake structure
Arrangement be water intake engineering success or failure key.The arrangement of intake structure is affected by many factors, the main table of its knowledge question of water conservancy
Now to take guaranteed extent, Sediment Siltation and flow-shape of the water yield etc., safe operation of these problems to intake structure has
Very big impact.For the ease of diversion and prevent silt from entering channel, intake should typically be located at the concave bank of tortuous channel, when recessed
When bank does not have appropriate position, it is also possible to be built in straight section.It is well known that Solution of Flow in Curved Channel is acted on by centrifugal intertia force,
There is horizontal water surface slope, i.e. concave bank side water surface height in the cross-section of river, at convex bank, the water surface is low.Current when bend is flowed through, due to weight
Cross current is formed in the collective effect of power and centrifugal force, section.Bend cross current is moved, and exacerbates silt on transverse section
Defeated shifting, river course knee, convex bank water velocity be little, and silt is easily deposited, and riverbank is relatively delayed；Concave bank water velocity is big, and riverbank is invaded
Erosion, riverbank are steeper, and silt is difficult deposition.Therefore, intake structure should be arranged in concave bank, and it is then to avoid greatly to be arranged in convex bank.However,
In Practical Project, many times limited by conditions such as landform, geology, or because earth clearance, engineering integral layout require etc. it is special
Reason, intake structure must run within convex bank.In this case, water diversion and sand control becomes what such intake structure was primarily solved
One of key technology.If not handling the anti-silting problem of diversion well, often causing intake silt to silt up causes water intaking difficult very
Scrap to engineering is caused.
The content of the invention
For the deficiencies in the prior art, it is to provide a kind of convex bank diversion anti-silting system that the purpose of the present invention is,
The system structure is simple, and preferably, diversion is secure for sediment prevention effect.
For achieving the above object, the present invention is achieved by the following technical programs：
The anti-silting system of a kind of convex bank diversion, including drainage channel and training wall located at river course convex bank, the drainage channel
One end be provided with intake, against streamflow flow direction, the intake arranges that the other end of the drainage channel is provided with several and leads
Husky bank.
Further, 2-4 times for intake length of the length of the training wall.
Further, before the training wall, the height of 1/3 part is design flood level, and after training wall, 2/3 partially below leading
1/3 part before stream wall.
Further, described several guide sand sills are arranged in parallel between straight line guide sand sill, and every guide sand sill.
Further, described several guide sand sills flow to into 35-45 degree angles with streamflow.
Further, the length of several guide sand sills is the 1/2 of the intake width.
Further, the quantity of the guide sand sill is 3-5 bars.
In sum, it is an advantage of the invention that：A kind of anti-silting system of convex bank diversion, which is included located at river course convex bank
Drainage channel and training wall, one end of drainage channel are provided with intake, and intake is arranged against streamflow flow direction, drainage channel
The other end is provided with several guide sand sills, and by layout for water intake under convex bank unfavorable conditions, water diversion and sand control problem is very prominent.By cloth
If training wall and guide sand sill measure, the anti-silting problem of diversion is solved rationally, effectively, therefore, it is arranged in the water intake engineering of convex bank
Good effect of water diversion and sediment control can also be reached.

Fig. 1 is the structural representation of the anti-silting system of convex bank diversion in the embodiment of the present invention；
1st, river course, 101, river course concave bank, 102, river course convex bank, 2, training wall, 3, guide sand sill, 4, the inner side edge of drainage channel
Wall, 5, the outside abutment wall of drainage channel, 6, intake.
Specific embodiment
Invention is further described below in conjunction with accompanying drawing and specific embodiment：
As shown in figure 1, a kind of anti-silting system of convex bank diversion, including drainage channel and training wall located at river course convex bank 102
2, one end of the drainage channel is provided with intake 6, and the intake 6 is arranged against 1 flow direction of river course, the drainage channel
The other end is provided with several guide sand sills 3.
2 times for 6 length of intake of the length of the training wall 2.
The height for leading 1/3 part before training wall 2 is design flood level, and after training wall 2,2/3 partially below training wall 2
Front 1/3 part.
Described several guide sand sills 3 are arranged in parallel between straight line guide sand sill, and every guide sand sill 3.Described several are led
Husky bank 3 is with 1 flow direction of river course into 35 degree of angles.
The length of several guide sand sills 3 is the 1/2 of 6 width of the intake.
The quantity of the guide sand sill 3 is 3.
River course 1 is respectively provided on two sides with river course concave bank 101 and river course convex bank 102, and by said system, drainage channel is located at river course
Between concave bank 101 and river course convex bank 102, and the inner side abutment wall 4 of drainage channel first, will be taken located at the side of river course convex bank 102
One section and river course 1 are built from the position downstream of the outside abutment wall 5 of drainage channel against 1 flow direction of river course arrangement in the mouth of a river 6
The close training wall 2 of bending radius, and three straight line guide sand sills 3 are set in the end of training wall 2.
2 length of training wall adopt 2 times of intake length, before training wall length 1/3 be drainage channel design flood level, water conservancy diversion
After wall 2,2/3 partially below 1/3 part before training wall 2.2/3 height is that drainage channel design flood level 2/3 is high to training wall (2) afterwards
Degree.
Three straight line guide sand sill 3 be arranged in parallel, and, into 35 ° of angles, length is intake width for angle and 1 flow direction of river course
1/2,3 height of front two guide sand sills is drainage channel design flood level 1/4, and is not less than 1.0 meters, and Article 3 guide sand sill 3 is high
Spend for 0.5 meter.
Arranging three 3 one side of guide sand sill can make 2 contraction in length of training wall, and silt on the other hand can also be avoided to lead
The tail end accumulation of stream wall 2.
After arranging training wall 2, from 1 plane of river course, the current cross-section of river is narrowed down, but due to river course convex bank 102
Subregion is recirculating zone, and effective cross-section of river of main flow not occupies 1 section of whole river course.Therefore, postponed using the cloth, river course
1 water surface longitudinal gradient drop is not changed significantly, and the water movement situation of main stem is more smoothed out on the contrary.Water level inside and outside training wall 2
Difference also less, is varied from according to 1 degree of crook of river course and the ratio for taking river course 1, typically in the range of 5～25cm.
In sum, the invention has the beneficial effects as follows：Layout for water intake under convex bank unfavorable conditions, water diversion and sand control problem ten
Divide protrusion.By laying training wall and guide sand sill measure, the anti-silting problem of diversion is solved rationally, effectively, illustrate to be arranged in convex
The water intake engineering of bank can also reach good effect of water diversion and sediment control.And the system structure is simple, preferably, diversion has sediment prevention effect
Ensure.
For a person skilled in the art, other can be made various corresponding according to above technical scheme and design
Change and deformation, and all these change and deformation should all belong within the protection domain of the claims in the present invention.
