Description
Technical field
The utility model relates to bridge structure technical fields, in particular to a kind of Bridge Pier bifurcation structure.
Background technique
Pier foundation in existing highway bridge pier water, in the majority with upright rule-based approach, water side is big, the souring of water
Greatly, since mountain area valley bridge water flow is big and speed is fast, water environment is complicated, water to wash away concealment very high, frequently result in bridge
Pile foundation damages and postpones discovery, not only reduces the bearing capacity of bridge pier and abutment, seriously endangers bridge health, ties up simultaneously
It is also very high to accomplish this.Existing pier protection is affected to the natural section in riverbed based on cushion cap revetment or fill block stone throwing protection,
And higher cost.
To solve this problem, the China of entitled " a kind of pier cap structure " of Patent No. " CN204982638U " is real
A kind of bridge pier structure is described with new patent, the long axis of the pier cap of the bridge pier is arranged along water (flow) direction, in the vertical of water flow
On face, the lower edge of pier cap is streamlined.On the facade of water flow, the lower edge of pier cap be it is streamlined so that water flows through
When crossing cushion cap, water flow streamline and cushion cap lower edge line are seamlessly transitted on facade, cushion cap upstream face, bottom and back side will not shape
At recirculating zone, or it is significantly reduced circulating flow strength, to reduce local head loss caused by cushion cap, reduces upstream water level and stop up
Height, to reduce the influence to flood control.But the program still has some problems, pier cap first is not completely to flow
Linear structure, the destruction in order to avoid floating material to pier cap are provided with longitudinal ridge, longitudinal ridge on the pier cap of the program
For the planar structure flowed vertically to, resistance to water-flow actually still will increase；Secondly, the program only address only pier cap by
The problem of water impact, but actually bridge pier also will receive water impact effect in some cases, but the program is not
It is mentioned to and how to handle the problem of bridge pier is by impact.
Summary of the invention
The purpose of this utility model seeks to the bridge pier for solving the prior art mentioned in above-mentioned background technique and bridge pier is held

Pier cushion cap upper surface.
Second point of water platform is the reinforced concrete structure that level cross-sectionn is isosceles triangle, second
Middle line of the middle line of lug boss with bridge pier along flow direction is overlapped.
Further the angle on the bottom edge of the second point of lower end Shui Tai side flow direction vertical with bridge pier lower end is
30~60 °.
Further second point of water platform is the armored concrete down big up small, its level cross-sectionn is triangle
Structure.
The further first point of upper end Shui Tai area is greater than the second point of lower end Shui Tai area.
The further pile foundation is the pile group of more fixed reinforced concrete pile compositions in water.
The bridge pier and pier cap that the utility model basis there is not water depth and designs within the scope of water surface certain altitude pour one
Body formula bifurcation structure, combines together with bridge pier and pier cap, plays the role of that pier is protected to be hit by current scour or ice cube.
The bifurcation structure of the utility model is reinforced concrete structure, and materials are convenient, is easily implemented, not with bridge main body structure
Conflict, can construct simultaneously, not occupy river course flood space additionally, and low cost has reduced or remitted pier protective equipment.
