The invention discloses a highway parabola corrugated steel bar flexible guardrail structure which comprises a reinforced concrete stand column. Connecting bolts are pre-buried in the reinforced concrete stand columns; a concrete foundation is poured outside the reinforced concrete stand column, and the reinforced concrete stand column is fixed to a foundation through the concrete foundation. The parabolic corrugated steel bars are connected with the connecting bolts in the reinforced concrete stand columns through the sleeve nuts; the stand column buffering device is fixed to the reinforced concrete stand column through the buffering device fixing steel bars. A flexible protection system is formed by the parabola corrugated steel bar structure and the reinforced concrete stand column, the parabola corrugated steel bars generate rapid straightening and large deflection deformation after being subjected to impact force, impact energy is absorbed, flexible impact is formed, and damage to a vehicle, a driver and passengers caused by impact is reduced; damage caused when a vehicle collides with the stand columns is reduced through the waste tires fixed to the stand columns, and therefore a flexible protective fence structural system is formed.
本发明公开了一种公路抛物线波形钢筋柔性护栏结构，包括：钢筋混凝土立柱；钢筋混凝土立柱内预埋连接螺栓；钢筋混凝土立柱外浇筑混凝土基础，钢筋混凝土立柱通过混凝土基础固定在地基上；抛物线波形钢筋通过套筒螺帽与钢筋混凝土立柱内的连接螺栓连接；立柱缓冲装置通过缓冲装置固定钢筋固定在钢筋混凝土立柱上。本发明利用抛物线波形钢筋结构与钢筋混凝土立柱形成柔性防护体系，抛物线波形钢筋受到冲击力后产生快速拉直和挠曲大变形，吸收撞击能量，形成柔性撞击，减小撞击对车辆和驾乘人员的损伤，当车辆撞击在立柱上时，依靠固定在立柱上的废旧轮胎减小车辆碰撞立柱的损伤，从而形成一个柔性防护栏结构体系。
