Abstract
The utility model relates to a bridge pier of a bridge. The integral bridge pier from the top to the end extends towards a bridge floor side edge to form a closed angle end portion towards the direction of the water flow; the closed angle end portion has a first side surface and a second side surface; the first side surface and the second side surface forms an included angle; the water flow is directed to pass at two sides of the bridge pier by using the first side surface and the second side surface, so that the impact force of the water flow is reduced; damage on the bridge pier because of overlarge impact force of the water flow is effectively avoided; and security and service lifetime of the bridge usage is increased.
Description
Technical field
The utility model relates to bridge, especially relates to the bridge pier of bridge.
Background technology
The high water in mountain, China south is anxious, and typhoon or heavy rain always form mud-rock flow.The impulsive force of mud flow is big, because existing bridge pier shape all is cylindrical, bridge pier is in face of a side of current, and the impact of bearing current fully is easy to be washed away by mud-rock flow or flood.Referring to Fig. 1, be the schematic diagram of traditional bridge, bridge floor 1 is erected on a plurality of bridge piers 2, and the similar cylinder-shaped body of bridge pier 2 bears the frontal impact power from powerful current, current can't be arranged smoothly and is cushioned.If current are too big, along with the passing of attack time, bridge pier 2 can be washed away naturally, causes the loss of people's life and property, therefore, safeguards the structural safety of bridge, particularly bridge pier, and is very urgent.
Summary of the invention
The purpose of this utility model is to provide a kind of cost, simple improvement type bridge pier saved.Described bridge pier is extending to form a wedge angle end toward the bridge floor side down on the whole on the direction of current, described wedge angle end has first side surface and second side surface, and this first side surface and this second side surface folder are established an angle.The angular range of this angle is the 15-45 degree.The last plane of wedge angle end is littler than its bottom, and length is shorter; Bottom wedge angle with the wedge angle end behind the last plane formation wedge angle of wedge angle end is linked to be the slope line, and the slope line is a horn structure.
Preferably, bridge pier backwater one side forms the angular shape of symmetry.
Preferably, bridge pier is " V " tee section.
The utility model utilization forms first side surface and second side surface of wedge angle, the guiding current pass through toward these bridge pier both sides, can reduce impact force of water flow, effectively avoid this bridge pier being caused damage, improve safety and life-span that bridge uses because of water flow impact pressure is excessive.
Description of drawings
Fig. 1 is the schematic diagram of traditional bridge.
Fig. 2 is the schematic diagram according to bridge pier of the present utility model.
Fig. 3 is the schematic diagram according to another embodiment of bridge pier of the present utility model.
Fig. 4 is the sectional drawing according to another embodiment of the present utility model, shows that bridge pier is " V " tee section.
The specific embodiment
Referring to Fig. 2, only provided two bridge piers 2 among the figure, bridge pier 2 extends to form a wedge angle end 21 at the following on the whole side toward bridge floor 1 on the direction of current, and length is 3-10 rice.The wedge angle of formation foremost of wedge angle end 21 as shown in the figure, to meet flood, can reduce the impact force of flood.
Described wedge angle end 21 has first side surface and second side surface, and first side surface and second side surface folder are established an angle.Two side surfaces of wedge angle end 21 are the plane.The preferred range of angles of this angle is the 15-45 degree.
The purpose of wedge angle end 21 is in shunting.Because wedge angle end 21 is increase parts of bridge pier 2, can increase the floor space that bridge pier 2 is fixed in the riverbed, institute is so that bridge pier 2 is more firm.Because current are 21 shuntings from the wedge angle end, flow velocity increases, and strengthens the strength of washing away the riverbed, so the ground in riverbed, auspicious 21 both sides of bridge pier 2 and wedge angle should be strengthened.
In the drawings, bridge pier 2 has only a side to adopt angular shape, and still, for reducing the eddy current that forms in backwater one side, backwater one side also can form the angular shape of symmetry.
Another embodiment of the utility model as shown in Figure 3, the last plane of wedge angle end 21 is littler than its bottom, and the last plane of wedge angle end 21 becomes wedge angle than brachmorphy, and then is linked to be slope line 22 with the bottom wedge angle of wedge angle end 21, slope line 22 is horn structure, as shown in the figure.
Referring to Fig. 4, shown that according to another embodiment of the present utility model roughly identical with structure shown in Figure 2, difference is that this bridge pier is " V " tee section, has wedge angle end 21 equally.
Claims (3)
1. bridge pier, described bridge pier is extending to form a wedge angle end toward the bridge floor side down on the whole on the direction of current, described wedge angle end has first side surface and second side surface, two side surfaces are the plane, this first side surface and this second side surface folder are established an angle, and the angular range of this angle is the 15-45 degree, it is characterized in that, the last plane of wedge angle end is littler than its bottom, and length is shorter; Bottom wedge angle with the wedge angle end behind the last plane formation wedge angle of wedge angle end is linked to be the slope line, and the slope line is a horn structure.
2. bridge pier as claimed in claim 1 is characterized in that, bridge pier backwater one side forms the angular shape of symmetry.
3. bridge pier as claimed in claim 1 is characterized in that, bridge pier is " V " tee section.
