Description

crash barrier

technical field

The invention relates to the technical field of road guardrails, in particular to an anti-collision guardrail.

Background technique

With the continuous development of economic construction, transportation is becoming increasingly busy. Traffic accidents are currently the most frequent occurrences in road sections or highway bridge sections. In order to reduce the occurrence of traffic accidents, various guardrails are installed on both sides of the road. Since the guardrails are made of iron structure and inelastic, rigid guardrails have strong protection ability. However, when a car collides with the guardrails, Under the action of instantaneous impact load, the guardrail basically does not move or deform. The energy absorption during the collision process depends on the plastic deformation of the car itself, the frictional contact between the car and the guardrail, and the car's movement along the barrier. The climbing of the guardrail and the change of the driving direction of the car. Impact injuries to accident vehicles and occupants, especially in some small-radius curved road sections, often cause the disintegration of large vehicles and cause loss of control, or serious injury or even death.
