Abstract
The invention relates to a large dam with an energy dissipation capability, which comprises a dam body (1), stop blocks (2), diversion piers (3) and a flow stopping threshold (4), wherein the stop blocks (2) are distributed on the dam body (1), the diversion piers (3) are arranged at the bottom of the dam body (1) and arranged on the vertical line in the water flow direction at intervals, the flow stopping threshold (4) is arranged below the diversion piers (3), the flow stopping threshold (4) is provided with a flange parallel to the water flow direction, and a through hole (41) is formed on the flow stopping threshold (4). Therefore, the service life of a channel can be prolonged.
Description
One, technical field
The invention belongs to the water conservancy projects technical field, relate to a kind of dam, especially a kind of dam that is suitable for tackling on the river course that is used for agricultural irrigation with energy dissipating.
Two, background technology
People often need build water channel in order to keep flowing of current, in order to keep the water yield in certain zone; Often on water channel, build dam, so dam is an important water conservancy device, in order to prolong the application life in river course; Reduce current as best one can to the washing away of river course, therefore need through the water velocity of dam slack-off, existing dam with energy dissipating; Because the current energy dissipator of design is unreasonable, makes the slack-off effect of speed of current undesirable.
Three, summary of the invention
In order to overcome above-mentioned technical disadvantages, the purpose of this invention is to provide a kind of dam with energy dissipating; Prolonged the application life in river course.
For achieving the above object, the technical scheme that the present invention takes is to include dam body, stopper, baffle pier and block the stream bank; Distributed and arranged has stopper on dam body; The bottom of dam body is provided with baffle pier, and baffle pier is provided with a plurality of and is arranged on the vertical line of water (flow) direction by compartment, below baffle pier, is provided with and blocks the stream bank; Block the stream bank and be provided with the flange parallel, block the stream bank and be provided with through hole with water (flow) direction.
When using present embodiment, when current passed through dam body, flow action was on stopper; Water velocity is slack-off, and current are through baffle pier the time, under the effect of baffle pier; Water velocity is slack-off once more, when the stream bank is blocked in arrival, under the flange acting in opposition that blocks the stream bank; Through hole through blocking the stream bank flows out, and makes the slower of current change; Owing to designed stopper, baffle pier and blocked the stream bank, make the flow velocity of current slack-off, reduced the washing away of river course, therefore prolonged the application life in river course.
The present invention has designed, and the cross section of baffle pier is provided with ellipse.
Four, description of drawings
Accompanying drawing is a sketch map of the present invention.
Five, the specific embodiment
Accompanying drawing is one embodiment of the present of invention, specifies present embodiment in conjunction with accompanying drawing, includes dam body 1, stopper 2, baffle pier 3 and blocks stream bank 4; Distributed and arranged has stopper 2 on dam body 1; The bottom of dam body 1 is provided with baffle pier 3, and baffle pier 3 is provided with a plurality of and is arranged on the vertical line of water (flow) direction by compartment, below baffle pier 3, is provided with to block stream bank 4; Block stream bank 4 and be provided with the flange parallel, block stream bank 4 and be provided with through hole 41 with water (flow) direction.
In the present embodiment, the cross section of baffle pier 3 is provided with ellipse.
When using present embodiment, when current passed through dam body 1, flow action was on stopper 2; Water velocity is slack-off, and current are through baffle pier 3 time, under the effect of baffle pier 3; Water velocity is slack-off once more, when stream bank 4 is blocked in arrival, under the flange acting in opposition that blocks stream bank 4; Through hole 41 through blocking stream bank 4 flows out, and makes the slower of current change.
Claims (2)
1. dam with energy dissipating; It is characterized in that: include dam body (1), stopper (2), baffle pier (3) and block stream bank (4); Go up distributed and arranged at dam body (1) stopper (2) is arranged; The bottom of dam body (1) is provided with baffle pier (3), and baffle pier (3) is provided with a plurality of and is arranged on the vertical line of water (flow) direction by compartment, is provided with in the below of baffle pier (3) to block stream bank (4); Block stream bank (4) and be provided with the flange parallel, block stream bank (4) and be provided with through hole (41) with water (flow) direction.
