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 structures
And its construction method.
Background technique
Bridge be traffic engineering important component and weak link and traffic engineering operation during need emphasis to protect
The object of shield.Bridge pier is the key position of bridge, decides the monolithic stability of bridge structure.However, emerging with different types of rridges
The raising with traffic capacity is built, the traffic accidents for hitting bridge in relation to ship (vehicle) are also increasing, the generation of such accident,
Both the security of the lives and property for having endangered people, will also result in interruption of communication leads to bigger loss, therefore takes anticollision to arrange on bridge
It applies particularly important, basic goal is: preventing bridge recurring structure due to the impact force of ship (vehicle) from damaging, while as far as possible
Protection ship (vehicle) loss is preferably minimized.
It is existing researches show that Crashworthy mechanism can be summarized as it is following several: (1) by the recovery elasticity of structure or material itself
The ability of deformation converts and discharges Impact energy, extends collision time, to reduce impact force, protects bridge；(2) anticollision is relied on
The lateral deflection of facility, bending failure absorb crash energy, achieve the purpose that protect bridge；(3) Impact energy of ship is converted
For the kinetic energy of water around the potential energy and weight of weight；(4) the collision energy of the joint flexible deformation snubber ship of pile group is utilized
Amount, makes entire guard system common eigenvector absorb ship kinetic energy.Anticollision device, collision-prevention device based on above-mentioned mechanism respectively has one in practical
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 will affect navigation channel, 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 steel easy-to-rust in water throughout the year；It is all kinds of slow
It rushes the energy that material is absorbed and is essentially converted to act on horizontal applied force on bridge pier, only the active force active area
It will spread significantly, and be effectively reduced local action intensity, bridge pier is protected 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.
Summary of the invention
Goal of the invention: the first object of the present invention is to provide a kind of lateral impact power Partial Conversion that can will be generated when hitting
For the vertical pressure to bridge pier, the combined bridge pier anticollision structure of the lateral stability of bridge pier is improved.
