The bridge transition guardrail is arranged between a bridge guardrail and a road guardrail, the guardrail comprises an anti-collision corrugated plate, a supporting column and a protective cross beam, the bridge transition guardrail further comprises a telescopic device, the telescopic device comprises a supporting seat, the supporting seat is fixedly installed on a bridge guardrail section roadbed, and a telescopic groove is formed in the surface of the telescopic device; the hinge seats are fixedly mounted on the sides, away from the road surface, of the guardrail sections; one end of the connecting rod is hinged to the hinge seat, so that the connecting rod can rotate around the hinge seat, and the other end of the connecting rod extends into the telescopic groove of the supporting seat and can slide in the telescopic groove. According to the bridge transition guardrail, the displacement amount of the expansion joint of the bridge guardrail foundation is converted into the longitudinal displacement amount of the expansion device through the expansion device, it is guaranteed that the transition guardrail and the bridge guardrail roadbed are relatively stable, and meanwhile the overall anti-collision performance of the guardrail can be improved.
本申请公开了一种桥梁过渡护栏，设置于桥梁护栏与公路护栏之间，所述护栏包括防撞波纹板、支撑柱以及防护横梁，还包括伸缩装置，所述伸缩装置包括支撑座，固定安装于桥梁护栏段路基上，且表面开设有伸缩槽；铰接座，固定安装于护栏段远离路面一侧；连接杆，一端铰接与铰接座，从而使得连接杆可围绕铰接座转动，另一端延伸进入支撑座的伸缩槽并可在伸缩槽中滑动。本申请的桥梁过渡护栏通过伸缩装置，将桥梁护栏地基伸缩缝的位移量转变成伸缩装置的纵向位移量，保证过渡护栏与桥梁护栏路基的相对稳定，同时能够提升护栏的整体防撞性能。
