Improvement method of road guardrail stand column
The invention belongs to the technical field of road guardrail upright post improvement, and discloses an improvement method of a road guardrail stand column.The method aims to reduce the rigidity of a dynamic guardrail when an automobile collides with the guardrail by cutting a stand column to form gaps, holes, notches and the like on the wall of the stand column. The method comprises the following steps: taking any position of the stand column as a cutting center; drawing the cutting size on the stand column according to the pre-designed size, shape and cutting direction; and cutting the stand column by a tool according to the drawn size to improve the stand column. By improving the stand column, the dynamic rigidity of the stand column is reduced, the stand column can better absorb energy generated during automobile collision, when the stand column subjected to slotting treatment are subjected to automobile collision, large deformation can be generated, the collision energy can be better absorbed, the rigidity of the stand column of the guardrail can be reduced, the automobile has a buffering process, and the automobile can be better protected; and meanwhile, the automobile is prevented from being seriously damaged, harm of collision to people in the automobile is reduced, and more cost is saved.
本发明属于公路护栏立柱改进技术领域，公开了一种公路护栏立柱改进方法，通过对立柱切割，造成立柱壁上形成缝隙、孔洞、缺口等，目的是在汽车与护栏碰撞时减少动态护栏的刚度，以立柱的任意位置处为切割中心；按预先设计好的尺寸形状和切割朝向在立柱上画出切割的尺寸；用工具在立柱上按照画好的尺寸进行切割，对立柱改进。本发明通过对立柱进行改进，减少立柱的动态刚度，使之更好的吸收汽车撞击时产生的能量，经过开缝处理的立柱在遭受汽车撞击时，会产生较大的变形，能较好吸收撞击能量，减少护栏立柱的刚度，使汽车有缓冲过程，更好的保护车辆的作用，同时避免汽车遭受严重破坏，降低撞击对车内人员的伤害，更加节约成本。
