Description

Technical Field

[0001] The utility model relates to the technical field of road safety protection, in particular to an anti-collision guardrail for a highway. Background Art

[0002] Highway guardrail is a kind of traffic facility. The main functions of highway guardrail include protecting the safety of pedestrians and vehicles. The speed on the highway is high, and the guardrail can effectively prevent pedestrians and non-motor vehicles from entering the highway, thereby reducing the probability of traffic accidents. In the event of an accident, the guardrail can prevent the vehicle from running off the road and reduce the possibility of secondary injuries; separate lanes and guide the line of sight. By setting signs and markings, highway guardrails can regulate the vehicle driving area and reduce violations, such as crossing the central dividing strip or lane line to enter the opposite lane, thereby ensuring the smooth flow of roads and transportation safety, etc.

[0003] However, the existing highway guardrails have some defects or shortcomings:

[0004] 1. As expressways can accommodate speeds of 120 km / h or even higher, the impact forces attached to vehicles traveling on expressways are very high. Especially when some large vehicles collide with guardrails in accidents, the guardrails are easily broken under the huge impact force, causing the out-of-control vehicles to run off the road, thus causing greater damage to the vehicles and the drivers and passengers;

[0005] 2. The highway guardrail itself has high hardness and strength. When a vehicle accident occurs, it will cause a rigid collision between the vehicle and the guardrail, which will cause a great impact on the vehicle, and thus greatly increase the damage to the vehicle and the driver and passengers.
