Technical Field

The invention relates to the technical field of protective guards, in particular to an anti-collision early warning protective guard for a highway.

Background

The guard rail is a traffic safety facility arranged at the outer side of a road shoulder, a traffic separation belt, sidewalk curbs and other positions. The collision energy is absorbed through self-deformation or vehicle climbing, so that the driving direction of the vehicle is changed, the vehicle is prevented from going out of the road or entering an opposite lane, and the injury to passengers is reduced to the maximum extent. Roadside guard rails are used to protect vehicles and occupants from collisions with natural or artificial objects located beside roads. It is important to note that a vehicle impacting the traffic guard rail may damage both the vehicle/passenger and the guard rail itself. The damage caused by a crash barrier is generally less severe than a crash of a component located behind the barrier, and thus traffic barriers represent a compromise between these two considerations. In addition to protecting vehicles, traffic protection barriers are also used to shield pedestrians, maintenance/construction personnel, or cyclists from errant traffic. In its most basic form, the traffic guard rail is designed to prevent a vehicle leaving the roadway from hitting a stationary object. The guard rail first blocks an accident vehicle and then makes it change direction. Because of the variability of vehicle impacts and the destructive effect at high speeds, a comprehensive full-scale destructive test should be introduced to ensure the safe reliability of the traffic guard rail to be used.
