Abstract
The utility model relates to a flexible energy dissipating car collision proof safe device used for a bridge pier and provided with a hollow packing structure, which belongs to the technical field ofsafety protecting device in bridge engineering construction, and overcomes the problem in the prior art that the safety of the car, the passersby and the bridge pier is difficult to guarantee in caseof rigid collision between the car and the bridge pier. The car collision proof safe device adopts the technical scheme that the flexible energy dissipating car collision proof safe device used for the bridge pier and provided with the hollow packing structure comprises a steel anti-collision wall. The car collision proof safe device is characterized in that the anti-collision wall is tubular, theinternal part thereof has a hollow structure which is filled with elastic energy dissipating material, the bottom of the anti-collision wall is a plane and extends outward to form an outer eave, andrivets are arranged on the outer eave in a penetrating way; energy dissipating parts are respectively and horizontally arranged at the upper end and the lower end of the inner side of the anti-collision wall. Compared with the prior art, the car collision proof safe device has the following advantages: firstly, the effect is good; secondly, the structure is simple, the construction is easy, the engineering investment is low, and the maintenance is convenient.
Description
Technical field
The utility model relates to safety device technical field in the bridge engineering construction, is specifically related to a kind of flexible energy dissipation type pier anti-collision safety device that adopts hollow interstitital texture.
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 purpose of this utility model provides a kind of flexible energy dissipation type pier anti-collision safety device that adopts hollow interstitital texture, 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 utility model is: a kind of anti-car collision safety device of flexible energy dissipation type that adopts hollow interstitital texture, the crashproof wall that comprises steel, its special character is: described crashproof wall is a tubular, this crashproof pars intramuralis is a hollow-core construction, is filled with elasticity energy dissipating material in it, and the bottom of crashproof wall is the plane, the bottom extension forms outer eaves, is equipped with holdfast on the eaves outside; Be horizontally disposed with energy dissipation piece respectively on the upper and lower side of described crashproof wall inboard.
The horizontal section of above-mentioned crashproof wall is annular or runway shape.Has stronger crashworthiness than the square-section.
The vertical hollow section of above-mentioned crashproof wall is a rectangle.Simple in structure, be easy to processing, transportation and installation.
The elasticity energy dissipating material that above-mentioned crashproof pars intramuralis is filled is modified polypropene or MPS or high-damping rubber, owing to have stronger recovery deformability, therefore, in dissipation automobile impacting energy, also can recover rapidly and can continue use even 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, the utility model has the advantages that:
1) the utility model adopts crashproof wall that is filled with elasticity energy dissipating material and the energy dissipation piece with elasticity dissipating functions to form the strong elasticity energy dissipator of globality, this device can effectively guarantee: even owing to the high speed of automobile is clashed into energetically, when causing anticollision device, collision-prevention device to collide bridge pier inevitably, its impact 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, guaranteed the safety of automobile and bridge pier;
2) the safety apparatus structure is simple, construction is easy, less engineering investment; And because of having stronger recovery deformability, therefore easy to maintenance, have good social economic value.
