Road guardrail with collision protection structure
The invention relates to the field of road guardrails, in particular to a road guardrail with a collision protection structure, which comprises a base. By means of the arranged rubber buffer columns,when an automobile collides with the guardrail, the automobile can make contact with the rubber buffer columns firstly, due to the material characteristics of the rubber buffer columns, the problem that the automobile is seriously damaged due to rigid collision is solved, and after the automobile collides with the rubber buffer columns, the speed of the automobile can be buffered; and when the rubber buffer columns cannot completely reduce the speed of the automobile, the automobile is decelerated and buffered again under the resistance of the rubber buffer block, even if the speed of the automobile cannot be completely reduced, the head of the automobile can be in contact with the rubber sheet, and the rubber sheet can flexibly buffer and decelerate the automobile again. When the rubber sheet cannot bear impact force and is broken, the automobile is forced to stop under the protection of the metal protection plate, the automobile is buffered and decelerated in the previous steps, andthe speed of the automobile is greatly reduced.
本发明涉及公路护栏领域，具体的说是一种带有碰撞保护结构的公路护栏，包括底座。通过设置的橡胶缓冲柱，当汽车撞向护栏时，汽车会先与橡胶缓冲柱接触，橡胶缓冲柱由于其材料的特性，使得汽车不会受到刚性撞击而严重受损的问题，并且汽车在于橡胶缓冲柱发生碰撞后，汽车的速度能够得到缓冲，当橡胶缓冲柱无法将汽车的车速完全降下后，汽车的车辆在橡胶缓冲块的阻力下再次得到减速缓冲，即使依旧无法完全将汽车的车速降下后，汽车的车头会与橡胶片接触，橡胶片能够对汽车再次进行柔性缓冲减速，当橡胶片无法承受冲击力而断裂开时，汽车会在金属防护板的防护下逼停，此时的汽车经过前序的多种缓冲减速，其车速大大降低。
