Description
Technical field
The present invention relates to a kind of highway bridge safety protection structure, more particularly to a kind of combined bridge pier anticollision structure
And its construction method.
Background technology
Bridge is the important component and weak link of traffic engineering, and needs emphasis to protect during traffic engineering operation
The object of shield.Bridge pier is the key position of bridge, decides the monolithic stability of bridge structure.It is however, emerging with different types of rridges
The raising with traffic capacity is built, the traffic accidents that bridge is hit about ship (car) are also on the increase, the generation of such accident,
Both the security of the lives and property of people had been endangered, will also result in interruption of communication causes bigger loss, therefore takes anticollision to arrange on bridge
Apply particularly important, its basic goal is：Prevent bridge because of the impact of ship (vehicle) and recurring structure damage, while as far as possible
Protection ship (vehicle) loss is preferably minimized.
It is following several that existing research shows that Crashworthy mechanism can be summarized as：(1) by the recovery elasticity of structure or material itself
The ability of deformation converts and discharges Impact energy, extends collision time, so as to reduce impact, protects bridge；(2) anticollision is relied on
The lateral deflection of facility, bending failure absorb crash energy, reach the purpose of protection bridge；(3) Impact energy of ship is converted
The kinetic energy of potential energy and weight ambient water for weight；(4) the collision energy of the joint elastic deformation snubber ship of pile group is utilized
Amount, makes whole guard system common eigenvector absorb ship kinetic energy.Anticollision device, collision-prevention device based on above-mentioned mechanism respectively has one in practicality
Fixed restrictive condition, such as currently used pile group mode, shell build husky cofferdam mode etc., apply in general to that water is shallow, geology feelings
The preferable occasion of condition, but navigation channel can be influenceed, and cost is too high；Steel construction casing energy-dissipating installation is disappeared using steel plastic deformation breakage
Can, but more difficult, while hull subject to damage when colliding is repaired after damage, in addition the steel easy-to-rust in water throughout the year；It is all kinds of slow
Rush the energy that material is absorbed and be essentially converted to act on horizontal applied force on bridge pier, only the active force active area
It will significantly spread, and be effectively reduced local action intensity, protect bridge pier not damaged by local assault, but suffered horizontal impact
Power still acts on the horizontal direction of bridge pier, is unfavorable for the lateral stability of bridge pier.
It would therefore be highly desirable to solve the above problems.
The content of the invention
Goal of the invention：The first object of the present invention is to provide one kind can be by lateral impact power Partial Conversion caused by shock
For the vertical pressure to bridge pier, the combined bridge pier anticollision structure of the lateral stability of bridge pier is improved.
