With overflow earth and rockfill dam.The latter is only limitted to spillwag chute and base of dam has the smaller weir of reliable protection facility, discharge per unit width.And factory building
It is combined together, as the power-house within the dam overfall dam of flood releasing structure, overflow type and the factory dam choosing more factory building top earial drainage
Joint flood discharge mode, can be used on high mountain glen area, and when being to lead big flow off, solution spillway and Power Plant position are not
A kind of approach of foot, is also the new model growing up from overfall dam.The overfall of overfall dam is due to being mingled with a large amount of silts in water
Easily block, make troubles to the overflow of dam body.
Content of the invention
In view of the shortcomings of the prior art, technical problem to be solved in the utility model is to provide a kind of water conservancy and sets
Apply anti-clogging overflow dam structure, prevent overfall from blocking, improve the reliability of overfall dam.
For solving above-mentioned technical problem, the utility model adopts the technical scheme that, a kind of water conservancy projects anti-clogging overflow
Dam structure, including dam body and the dam foundation, the dam foundation is arranged at dam body bottom, and the upstream face of dam body and the bottom of back side are respectively provided with
There is stable base, the lower end of dam body is provided with overflow pipe, and one end of overflow pipe is arranged at the outside of the upstream face of dam body, overflow pipe
The other end be arranged in dam body, one end that overflow pipe is arranged at the outside of the upstream face of dam body is provided with anti-blocking cover plate, overflow
The bottom of flow tube is provided with precipitation chamber；One end that described overflow pipe is arranged in dam body is connected with siphunculus, upper siphunculus with overflow
Flow tube is in 127 degree of angles, and upper siphunculus tail end is connected with lower through-tube, and lower through-tube is vertically arranged with upper siphunculus, and the bottom of lower through-tube is even
It is connected to a precipitation chamber；The middle part of described lower through-tube is connected with some overflow pipes be arrangeding in parallel, overflow pipe and overflow
Pipe be arranged in parallel, and overflow pipe bottom is provided with precipitation chamber.
Optimize, above-mentioned water conservancy projects anti-clogging overflow dam structure, in described precipitation chamber and precipitation chamber, be provided with net
Plate.
Optimize, above-mentioned water conservancy projects anti-clogging overflow dam structure, described overflow pipe top is provided with partial pressure plate, point
Pressing plate is bending plate, and the bending angle of partial pressure plate is 94.5 degree.
The utility model has the advantage of the drawbacks of it can overcome prior art, reasonable in design novelty.The application's
Overflow pipe is divided into four sections by design, and river first passes through overflow pipe, and due to the setting of upper siphunculus, river is in overflow pipe and upper siphunculus
Junction hindered form backflow, so silt of some can be deposited in precipitation chamber, and then river is by lower logical
Pipe, forms impact to lower through-tube bottom under gravity, and in impact process, a part of silt can be deposited to precipitation chamber
Interior, pass through overflow pipe overflow after river backflow, at this moment the flow velocity of river has been by the effect of upper siphunculus and lower through-tube
Reduce, in the river after the sediment overflow precipitating chamber, sediment charge substantially reduces.In order to improve river in overflow pipe
Sedimentation effect, upper siphunculus and overflow pipe are set in 127 degree of angles, in order to improve impact effect after lower through-tube for the river
Really, lower through-tube and upper siphunculus are vertically arranged.Dam body can be fallen overflow pipe for the pressure partial pressure of overflow pipe by the design of partial pressure plate
Both sides, prevent from being crushed by dam body using after body weathering for a long time because of overflow pipe.
Brief description
