Description
Technical field
The present invention relates to technical field of bridge engineering, and in particular to a kind of to prevent the high pier bridge bridge pier deviation device of big longitudinal slope.
Background technique
The prefabricated assembled Simply supported non-uniform beam bridge of Medium Span is widely used in mountainous area highway, however it is flexible high
Pier during construction or operation it is possible that larger deviation, especially between superstructure is adjacent at expansion joint position
The shift phenomenon of high pier pier top is more significant.
By big longitudinal slope bridge substantial influence, the pot bearing of bridge pier influences and the high-frequency resonance of heavy-load automobile in temperature,
Just the mechanical property of flexible high-pier is determined, it may be assumed that for flexible high-pier in the case where pot bearing limit rigidity is low, bridge main beam is not
Pipe is that expanded by heating or cooling shrinkage flexible high-pier are bound to generate longitudinal deviation toward upward slope direction, and specific reason can join
See periodical " granddad in the punishment of Guo Tong [1], Wang Jianqun [2] big longitudinal slope flexible high-pier bridge bridge pier deviation and its safety evaluation [J]
Road, 2016 (2) ".
Most domestic Bridge Design institute does not design high pier flexible pier clearly in Bridge Design and longitudinally limits
Position device is only merely to briefly explain bridge construction and finish to need to install longitudinal limiting device, but because do not design explicitly
Drawing and in the market also not ready-made limiting device for buying, so general unit in charge of construction after bridge construction not plus
Longitudinal limiting device is filled, is transfinited with causing just to occur in the one or two years after operation high pier deviation, bent cap goes up a slope with girder
Longitudinal deviation in direction transfinites, and bridge pad damage, expansion joint is caused to destroy, and the high unfavorable stress in pier bottom portion increases, moment of flexure stress
Increase severely, bridge pier pier bottom cracking, a series of diseases such as load carrying capacity of bridge decline.It handles bridge pier deviation and reinforces limit construction cost
Height, difficulty of construction is big, causes huge economic loss and economic benefit to unit of operation and local economy.
Application No. is 201510415496.3 Chinese patents to disclose a kind of high pier bridge pier top displacement spring limiter,
But it has the disadvantage that
(1) destroy to bridge beam body structure larger: stiffened steel plates A1 and beam body are connected and fixed using weldering nail form and beam body
Consolidation, ribbed stiffener B1 is also stressed member, 80-200KN horizontal force has been estimated under the influence of the temperature difference, inherently to girder construction
A kind of destruction.
(2) structure falls off, and limit is failed: in existing common practical bridge structure, beam body bottom surface and bent cap top surface
Spacing is in bridge in heavy-load automobile, and when temperature difference environment is larger, beam body stress variation, moment of flexure changes, and is easy under girder active force
Make weldering nail loose or dislocation, long necessarily will appear ribbed stiffener B1 loose or dislocation, limit failure.
In conclusion being badly in need of a kind of high pier bridge bridge pier deviation device of big longitudinal slope that prevents to solve existing in the prior art ask
Topic.
