Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of crash barriers, and in particular to a crash barrier device for highways. Background Technology
[0002] Highway crash barriers, as an indispensable traffic infrastructure in highways and municipal roads, are of paramount importance. They not only precisely delineate road driving zones, ensuring that all types of vehicles can travel orderly within designated areas, but also serve as a solid barrier in critical moments when vehicles lose control, effectively preventing vehicles from running off the road and greatly avoiding potential serious loss of life and property.
[0003] Traditional highway crash barrier designs typically consist of support posts deeply driven into the ground, and guardrail panels securely fastened to the posts with bolts and nuts. In the event of a highway accident, when a vehicle impacts the guardrail panel, the panel deforms, cleverly absorbing and dispersing the vehicle's impact energy, thus reducing the impact force on the vehicle's occupants.
[0004] However, it is worth noting that in the event of an accident, the car may directly collide with the support pillar. Because the support pillar is directly inserted into the ground, its cushioning effect is greatly reduced, resulting in a rigid collision between the vehicle and the support pillar. This situation often poses a significant risk of injury to the occupants of the vehicle. Utility Model Content
