Abstract
The invention discloses a flood discharge structure which comprises two side walls. The outer side of each side wall is provided with an arch dam, the dams are fixedly connected with the corresponding side walls, the inner side of each side wall is provided with a connecting unit and a water stopping unit, each water stopping unit is located under the corresponding connecting unit, one end of each of the water stopping unit and the connecting unit is fixedly connected to the corresponding side wall while the other end of each of the water stopping unit and the connecting unit is fixed on a dam pier, the dam piers and the side walls are on the same horizontal line, reinforcing ribs are connected between the dam piers and the side walls, steel columns are arranged inside the dam piers and the side walls, each steel column is composed of a plurality of steel bars, the steel columns are flush with the side walls and the dam piers, and an upper flow path and a lower flow path are respectively arranged between the dam piers. By the arrangement, flood can pass the dam piers smoothly without causing overflowing to wash out the dam piers, water patterns can be rapidly completed through self-energy of high-velocity water flow, water falling points transfer from dotted distribution to linear distribution, and a certain alleviation function is achieved.
Description
Technical field
The present invention relates to a kind of hydraulic engineering, particularly a kind of flood discharge structure.
Background technology
In design in the past, water retaining structure is the key water control project of Concrete Face Rockfill Dam, and its flood releasing structure is adopt Bank-run Spillway mostly.But most Reservoir region does not have suitable low-lying bealock to build Bank-run Spillway flood discharge, and Ba Dun two sides landform is also more precipitous.From work arrangement, spillway on bank lets out groove location often to be needed to turn, and the Solution of Flow in Curved Channel of high flow rate and rivers shock wave can only be solved in conjunction with hydraulic model test by empirical formula now, so not only complexity but also can not carry out timely prevention process, if and design unreasonable, be easy to cause current to destroy by rush of water Ba Dun, cause unnecessary economic loss.Therefore, need to design corresponding flood discharge structure, to meet flood discharge requirement, avoid the generation of unnecessary problem.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the problems referred to above, provides one that flood can be made smoothly by Ba Dun, and can not produce overflow phenomena, cause the Ba Dun that destroys by rush of water, and completes the flood discharge structure of flow shape by high-velocity flow self-energy fast simultaneously.
To achieve these goals, the technical solution used in the present invention is such: flood discharge structure of the present invention, comprise abutment wall, abutment wall is two, arch dam is provided with outside two abutment walls, arch dam is fixedly connected with abutment wall, both sides within the walls side are provided with linkage, both sides within the walls side are respectively equipped with linkage and antipriming, antipriming is positioned at below linkage, and antipriming and linkage one end are all fixedly connected on abutment wall, its other end is fixed on a Ba Dun, Ba Dun and abutment wall are in the same horizontal line, reinforcement bar is connected with between Ba Dun and abutment wall, and Ba Dun and abutment wall inside are equipped with steel column, steel column consists of several steel bar, and steel column is concordant with abutment wall and dam pier respectively, upper runner and lower flow channel is respectively equipped with between two dam piers, upper runner and lower flow channel height are between 20 to six ten centimetres.
Further, as a kind of concrete form of structure, antipriming cross section of the present invention is isosceles acute triangle structure.
Further, as a kind of concrete form of structure, linkage of the present invention is connected by asphalt emulsion with between abutment wall and dam pier.
Further, as a kind of concrete form of structure, asphalt emulsion thickness of the present invention is one to two centimetre.
Further, as a kind of concrete form of structure, upper runner of the present invention and lower flow channel soffit are equipped with base plate, and base plate is fixedly connected with upper runner and lower flow channel respectively.
Further, as a kind of concrete form of structure, arch dam of the present invention and abutment wall junction angle are 90 degree.
Compared with prior art, the invention has the advantages that: this flood discharge structure can make flood pass through Ba Dun smoothly, and can not overflow phenomena be produced, cause the Ba Dun that destroys by rush of water, complete flow shape fast by high-velocity flow self-energy simultaneously, make water-drop point change wire into by spot distribution to distribute, serve certain mitigation.
