Water transferring canal
Technical field
The present invention relates to a kind of water transferring canals.
Background technique
Currently, collect throughout the year, the river of large number of ground water flow is gradually slow with water velocity, and what is carried in water flow is thin
Sand, silt are also gradually deposited in river, the deposition of river fine sand, silt, make that riverbed is gradually increasing or even the riverbed in river is high
In ground, it is unfavorable for the conveying of river water.
Summary of the invention
The technical problem to be solved by the present invention is to how overcome the drawbacks described above of the prior art, to effectively utilize river
Water flow washes away the silt for administering channel deposit, substantially or significantly drops bed level, provide a kind of water transferring canal.
The present invention is achieved by the following technical solutions:
A kind of water transferring canal, several cross sections including being set in bottom of river channel are in the water delivery building block of " entering " font,
The water delivery building block includes segmental arc and slope section.
It is designed in this way, the segmental arc of " entering " font water delivery building block forms turbulent flow, and the slope section of " entering " font water delivery building block makes
River water medium-fine sand, silt are deposited along the gradient in bottom in short-term, while the fine sand, the silt that largely deposit are built in " entering " font water delivery
The turbulent flow that the segmental arc of block is formed is flushed away again, in this way, fine sand, the silt of bottom of river channel deposition are less, can significantly drop riverbed
Highly, the water flow in river is effectively utilized.
As optimization, the height of the segmental arc is 200-300mm, and radian is 20-90 degree.It is designed in this way, easy to process,
And effect is preferable.
As optimization, the length of the slope section is 2-4m.It is designed in this way, easy to process and effect is preferable.
The beneficial effects of the present invention are:
The present invention, structure is simple, design science, and bottom of river channel silt is not easy to deposit, and bed level is greatly reduced, effectively benefit
With the water flow in river, there is preferable practical application value and promotional value.
Detailed description of the invention
Water transferring canal is described further with reference to the accompanying drawing:
Fig. 1 is the partial cross sectional structural schematic diagram of water transferring canal.
In figure: 1 being bottom of river channel, 2 be water delivery building block, 2.1 be segmental arc, 2.2 be slope section, 3 be river water.
Specific embodiment
To make the objectives, technical solutions, and advantages of the present invention more comprehensible, right hereinafter, referring to the drawings and the embodiments,
The present invention is further described.
As shown in Figure 1, a kind of water transferring canal, several cross sections including being set in bottom of river channel 1 are in " entering " font
Water delivery building block 2, water delivery building block 2 include segmental arc 2.1 and slope section 2.2.The height of segmental arc 2.1 is 200mm, radian 60
Degree.The length of slope section 2.2 is 3m.
The beneficial effect of the embodiment of the present invention is: the segmental arc 2.1 of " entering " font water delivery building block 2 forms turbulent flow, " entering " word
The slope section 2.2 of shape water delivery building block 2 deposits river water medium-fine sand, silt in short-term in bottom along the gradient, while largely depositing
Fine sand, silt are flushed away again in the turbulent flow that the segmental arc of " entering " font water delivery building block is formed, and segmental arc 2.1 and slope sections 2.2
Size design is best using effect, in this way, fine sand, the silt of bottom of river channel deposition are less, can significantly drop bed level, effectively
Ground utilizes the water flow in river.
Above-mentioned specific embodiment is only specific case of the invention, is not that the invention has other forms of limitations,
Any person skilled in the art is changed or is modified as equivalent variations possibly also with the technology contents of the disclosure above
Equivalent implementations.But under the premise of all principles without departing from the technology of the present invention, according to the technical essence of the invention to above
Any simple modification, equivalent variations and remodeling, all shall fall within the protection scope of the present invention made by embodiment.
