System for preventing vehicle from colliding with bridge pier of overpass bridge

The invention provides a system for preventing a vehicle from colliding with a bridge pier of an overpass bridge. The two sets of concrete walls are arranged on the left side and the right side of a pier in the driving direction respectively, the guide structures are fixedly installed at the top ends of the concrete walls and completely surround the periphery of the pier, the energy absorption structure tightly wraps the outer wall of the pier, and the cross brace is perpendicular to the driving direction, stretches across the concrete walls and is fixedly installed between the guide structures. The guardrail is formed by the concrete wall body and the guide structure, pier surface protection is achieved through the pier periphery energy absorption structure, and the guardrail and pier surface protection jointly form a protection system. Through the guardrail, crossing, riding and crossing caused by vehicle collision can be prevented, and the side inclination value generated after vehicle collision is reduced
