Description
Technical field
The present invention relates to safety device technical field in the bridge engineering construction, be specifically related to a kind of flexible energy dissipation type pier anti-collision safety device of high efficiency, low cost.
Background technology
At present, the present situation of China's traffic safety is troubling, because the growth of the traffic volume, the contradiction of automobile and bridge (especially bridge crossing) is also outstanding further, the accident of automobile impacting bridge pier happens occasionally, can cause when serious that bridge pier collapses, car crash, bring life without redemption and property loss.Tracing it to its cause, is that this process lacks energy dissipation because automobile directly clashes into bridge pier and belongs to rigid impact, therefore destroys greatly.
In order to address this problem; some crashproof measures have also been taked in existing design; for example strengthen the bridge pier structure size; or bottom pier stud, pour into into a concrete in mass solid block; perhaps adopt protected modes such as steel pipe fence; though these measures have ensured the safety of bridge pier to a certain extent; but its aesthetic property and applicability are not strong; and still belong to rigid impact during the automobile impacting bridge pier; to automobile or pedestrian; potential safety hazard is not eliminated or is reduced, and does not meet the requirement of Safety Design and human oriented design.
Summary of the invention
The flexible energy dissipation type pier anti-collision safety device that the purpose of this invention is to provide a kind of high efficiency, low cost is difficult to ensure the problem of automobile, pedestrian and bridge pier safety when overcoming the automobile that exists in the prior art and bridge pier generation rigid collision.
For overcoming problems of the prior art, technical solution of the present invention is:
A kind of flexible energy dissipation type pier anti-collision safety device of high efficiency, low cost, the crashproof wall that comprises steel, its special character is: described crashproof wall is by big protection cylinder and little protection cylinder is sheathed forms, and the inside of big protection cylinder and little protection cylinder is hollow-core construction, wherein is filled with elasticity energy dissipating material; Be provided with spring component layer between big protection cylinder and the little protection cylinder, spring component layer is made of the uniform some springs of level; The bottom of big protection cylinder and little protection cylinder is arranged on the pedestal steel plate, is equipped with holdfast on the epitaxial part of pedestal steel plate; Be horizontally disposed with energy dissipation piece respectively on the upper and lower side of described little protection cylinder inboard.
The vertical hollow section of above-mentioned big protection cylinder and little protection cylinder is rectangle.
Above-mentioned spring is embarked on journey into the row setting.Be convenient to processing.
Be provided with dust excluding plate between the upper end of above-mentioned big protection cylinder and little protection cylinder.Prevent that dust and foreign material etc. from falling into, and influences the function of use of spring.
The horizontal section of above-mentioned big protection cylinder and little protection cylinder is annular or runway shape.Has stronger crashworthiness than the square-section.
Above-mentioned elasticity energy dissipating material is that modified polypropene or MPS or high-damping rubber are made.Owing to have a stronger recovery deformability,, in dissipation automobile impacting energy, also can recover rapidly and can continue use even therefore clashed into.
Above-mentioned energy dissipation piece is horizontally disposed sealing banded structure, is made by flexible plastic or rubber.Play installing and locating and use spacing effect.
Compared with prior art, advantage of the present invention is:
1) the safety device is compared with the crashproof measure of routine, adopt two groups of steel plate casings that are separated from each other, and at the inner elasticity energy dissipating material of filling of casing, the spring of certain density is set between two groups of casings, thereby form an elasticity energy dissipator that globality is strong, and certain safety stock gap is set between safety device and bridge pier, this is enough to guarantee: even owing to the high speed of automobile is clashed into energetically, impact when causing anticollision device, collision-prevention device to collide bridge pier inevitably is also little to be enough to opposing to bridge pier, when realizing pier anti-collision, can effectively avoid and reduce the damage of automobile and bridge pier;
2) the safety apparatus structure is simple, construction is easy, easy to maintenance, and less engineering investment, result of use are good, have good social economic value.
