Specific implementation mode
A kind of hydraulic engineering flood-discharge energy-dissipating pond, as shown in Figure 1, including energy dissipation tank ontology 1, in the energy dissipation tank ontology 1
There are three energy dissipation pier 2, the left and right sides wall of each energy dissipation pier 2 is both provided with for spacing side by side setting in the vertical direction of water (flow) direction
The top of groove 3, intermediate energy dissipation pier 2 is provided with top groove 4；The groove 3 and the extending direction and water (flow) direction for pushing up groove 4
Identical, the height of the groove 3 on 2 side wall of whole energy dissipation piers is from left to right sequentially reduced.
In order to improve the effect of energy dissipation of energy dissipation tank, the spacing distance and two in the present embodiment between adjacent two energy dissipation pier
Spacing distance between the energy dissipation pier and energy dissipation tank side wall of side is equal to the half of energy dissipation pier height.
In the present embodiment, in order to further ensure that energy dissipation tank plays effect of energy dissipation well, the energy dissipation pier is cuboid,
The 2/3 of the height of energy dissipation pier≤energy dissipation tank height；The width of energy dissipation pier Transverse to the flow direction is the half of energy dissipation pier height.
Optionally, the depth of the groove is the 1/5 of energy dissipation pier height；The length of groove is the width of energy dissipation pier water (flow) direction
Degree.
The height of energy dissipation pier should be less than energy dissipation tank height, and the half that the width of Transverse to the flow direction is energy dissipation pier height,
This is in order to which energy dissipation pier is fully located in energy dissipation tank, and when energy dissipation pier height is higher than energy dissipation tank, the part being higher by can not be consumed
Can, unnecessary engineering waste is caused, the width of energy dissipation pier Transverse to the flow direction can select as needed, in the present embodiment
It is selected as the half of energy dissipation pier height, is only a kind of preferred mode.
The setting depth of groove is the depth that groove gos deep into energy dissipation pier, and this depth is deeper, is for effect of energy dissipation
It is better, because of flow dispersion in a groove more, caused by resistance it is bigger, but depth of groove is deeper, will necessarily shadow
The stability of energy dissipation pier is rung, energy dissipation pier easy tos produce destruction, therefore, considers effect of energy dissipation and structural stability, this implementation
Select the depth of groove for the 1/5 of energy dissipation pier height in example；For the length of groove, due to being only to provide water stream channel,
The width of the length of energy dissipation pier water (flow) direction runs through entire energy dissipation pier, as shown in Fig. 2 ~ 4.
It should be noted that the height of the groove 3 in the present embodiment on 2 side wall of whole energy dissipation piers is from left to right sequentially reduced
It is that subregion is carried out to flow in the height direction after energy dissipation pier for flowing water, generates flow different in flow rate, promotes flow
Shock, improve effect of energy dissipation, from left to right successively reduce be in order to realize the order of flow short transverse subregion, further
Promote effect of energy dissipation, then it should be appreciated that comparing traditional energy dissipation tank, it is only necessary to make the groove on 2 side wall of energy dissipation pier
3 height are different, you can improve effect of energy dissipation to a certain extent, the program also belongs to the scope of protection of the utility model.
The top setting top groove 4 of intermediate energy dissipation pier 2 is to further increase the energy dissipating effect of energy dissipation tank in the present embodiment
Fruit can choose whether setting in actual application in top groove, in the scope of protection of the utility model according to actual needs
It is interior.
The embodiment of the utility model is elaborated above in conjunction with drawings and examples, but the utility model
It is not limited to the above embodiment, within the knowledge of a person skilled in the art, this can also not departed from
It changes or changes under the premise of utility model objective.
