The invention discloses a traffic anti-collision guardrail, and belongs to the technical field of guardrails, the traffic anti-collision guardrail comprises a plurality of groups of guardrail columns, one sides of the plurality of groups of guardrail columns are provided with guardrail panels, the bottoms of the guardrail columns are provided with supporting mechanisms, and the guardrail columns can relatively deflect around the axes of the supporting mechanisms. According to the invention, the energy-absorbing mechanism can move to push the energy-consuming plate to slide in the protection box, when the energy-consuming plate moves, the prestressed steel cables penetrating through the two sides can be extruded through the limiting hoops, and the prestressed steel cables can absorb external impact by using own tension, and can be reset by virtue of own prestress after energy-absorbing contact; continuous energy absorption and self-resetting capacity under the small impact condition can be improved, energy absorption strength can be improved through cooperation of an energy absorption mechanism and the prestressed steel cables, energy absorption protection for vehicles under front impact is met, impact is absorbed by the rear prestressed steel cables and the energy absorption boxes, the breakage rate of the guardrail panel is reduced, and the service life of the guardrail panel is prolonged. And the guardrail panel is prevented from splashing outwards to influence the safety.
本发明公开了一种交通防撞护栏，属于护栏技术领域，包括多组护栏柱，且多组护栏柱一侧设有护栏面板，所述护栏柱底部设有支撑机构，且护栏柱能够围绕支撑机构轴心处相对偏转。本发明中，吸能机构移动能够推动耗能板在保护盒内滑动，当耗能板移动时能够通过限位箍挤压两侧穿设的预应力钢缆，预应力钢缆能够利用自身拉力吸收外部冲击，并且在吸能接触后利于自身预应力进行复位，有利于提高小冲击情况下的持续吸能以及自复位能力，有利于通过吸能机构与预应力钢缆的配合，提高吸能强度，满足正面冲击下对车辆的吸能防护，并且冲击由后侧预应力钢缆以及吸能盒吸收，减少护栏面板的破碎率，避免护栏面板向外飞溅影响安全性。
