Description

Technical Field

[0001] The utility model relates to the technical field of guardrails, in particular to a traffic anti-collision guardrail. Background Art

[0002] In order to reduce traffic accidents, various guardrails are installed on both sides of the highway. Since the guardrails are made of iron structures without elasticity, rigid guardrails have strong protection capabilities. However, when a car collides with the guardrail, under the action of the instantaneous impact load, the guardrail basically does not move or deform. The energy absorption during the collision process relies on the plastic deformation of the car itself, the friction contact between the car and the guardrail, and the car climbing along the guardrail and the change of the car's driving direction. Impact damage to accident vehicles and occupants, especially in some small radius curves, often causes the disintegration of large vehicles and loss of control, or serious injuries or even death.
