Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Describe, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments wholely.Based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under not making creative work premise
Embodiment, broadly falls into the scope of protection of the invention.
The embodiment of the present invention is write by the mode gone forward one by one.
The most as shown in Figures 1 to 4, the structural representation of the damping device of the assembled bridge pier that Fig. 1 provides for the present embodiment.
Wherein, hollow arrow represents the direction of waving of flexible high-pier, and black arrow represents that damping means when waving of flexible high-pier moves
Direction.The embodiment of the present invention provides the damping device of a kind of assembled bridge pier, waves vibration damping, including setting for flexible high-pier
Putting in the curved channel 1 within bridge pier, the extrados of described curved channel 1 is down-set, is provided with in described curved channel 1
Damping means 2, described damping means 2 has and is in the primary importance of described curved channel 1 minimum point and leaves described curve
The second position of passage 1 minimum point, the damping means 2 being in the second position has the minimum point motion to described curved channel 1
Trend.
The damping device of the assembled bridge pier that the present invention provides, when flexible high-pier does not waves, damping means 2 is in curve
The minimum point of passage 1, when flexible high-pier waves because of external force, damping means 2 can move to the second position from primary importance,
The trend moved to the minimum point of curved channel 1 owing to being in the damping means 2 of the second position to have, at damping means 2 with bent
Under the cooperation of line passage 1, the swing to flexible high-pier is controlled so that swing reduce, therefore, use the application provide
Vibration absorber, can subtract and effectively become the vibration of operational phase flexible high-pier after bridge less.
As a kind of optimal way, the cross section of the curved channel 1 in the present embodiment is circular, and damping means 2 is filled circles
Ball.Under this optimal way, the primary importance that damping means 2 is in refers to that solid ball is in the minimum point of curved channel 1
Position, why solid ball is in primary importance is due to solid ball result under gravity, works as flexible high-pier
During because waving under external force such as wind action, filled circles club slides in curved channel 1, and now, filled circles club is from
One position is left, and is in the second position leaving primary importance, moves to the mistake of the second position at solid ball from primary importance
Cheng Zhong, produces flow impedance power between solid ball and curved channel 1, and solid ball makes reality under the effect of self gravitation
Heart ball has the mobile trend to primary importance, produces flow impedance power, flow impedance between solid ball and curved channel 1
Power and solid ball self gravitation all can stop solid ball to move to the second position from primary importance, thus reduce flexible high
The swing of pier.Further, the diameter of solid ball matches with the diameter in the cross section of curved channel 1, i.e. curved channel 1 can be right
The movement of solid ball plays effect of contraction.Wherein, solid ball material preferably employs lead.
In the present embodiment, curved channel 1 can be to be opened in the passage within flexible high-pier, now, inside flexible high-pier
The inwall of passage relatively smooth.Curved channel 1 is preferably mounted to the pipeline within flexible high-pier.Wherein, when curved channel 1
When being preferably mounted to the pipeline within flexible high-pier, curvilinear conduit can be to be embedded in inside flexible high-pier.Due to flexible high-pier
The highest, therefore, pier is hollow, and now, curvilinear conduit is fixedly mounted on the inwall of pier shaft by connector.
In the present embodiment, being provided with liquid in curved channel 1, the setting of liquid can increase damping means 2 at curve
The resistance of movement in passage 1, thus improve the effectiveness in vibration suppression to flexible high-pier.Wherein, liquid preferably employs viscoelastic fluid.
The curved channel 1 of the damping device of the assembled bridge pier that the present embodiment provides can be arranged on the pier cap of flexible high-pier
In, it is also possible to it is arranged in the pier shaft of flexible high-pier, certainly, it is preferred that, same with in pier shaft at the pier cap of flexible high-pier
Time vibration absorber is set.Owing to the pier cap of flexible high-pier is solid construction, therefore, vibration damping dress is set in the pier cap of flexible high-pier
When putting, its curved channel needs to be embedded in pier cap, and the pier shaft of flexible high-pier is hollow-core construction, therefore, at the pier of flexible high-pier
When arranging vibration absorber in body, its curved channel is connected with the inwall of pier cap body.
The present embodiment also provides for a kind of shock-dampening method, and for the vibration damping that waves of flexible high-pier, the method is by bridge pier
Portion arranges curved channel, arranges damping means to reduce the rocking vibration of flexible high-pier in curved channel, and damping means has
It is in the primary importance of curved channel minimum point and leaves the second position of curved channel minimum point, being in subtracting of the second position
The parts that shake have the trend moved to the minimum point of curved channel.
Wherein, arranging liquid in curved channel, liquid is preferably viscoelastic fluid.
Described above to the disclosed embodiments, makes professional and technical personnel in the field be capable of or uses the present invention.
Multiple amendment to these embodiments will be apparent from for those skilled in the art, as defined herein
General Principle can realize without departing from the spirit or scope of the present invention in other embodiments.Therefore, the present invention
It is not intended to be limited to the embodiments shown herein, and is to fit to and principles disclosed herein and features of novelty phase one
The widest scope caused.
