Description

Technical Field

[0001] This utility model relates to the field of guardrail technology, specifically a road and bridge guardrail. Background Technology

[0002] Bridges are generally structures built over rivers, lakes, and seas to allow vehicles and pedestrians to pass smoothly. Highway bridges are usually not only for vehicles, but also have pedestrian walkways at both ends. Therefore, guardrails are usually installed on highway bridges to protect pedestrians on the pedestrian walkways and to prevent vehicles from running off the bridge.

[0003] Road and bridge guardrails are important facilities for ensuring road traffic safety. They are designed to prevent vehicles from accidentally running off the road or bridge while driving, and to protect the lives and property of drivers and passengers.

[0004] The existing patent document with authorization announcement number CN221235908U describes a road and bridge guardrail, including a guardrail frame, guardrail tubes, and a base. The base is welded to the bottom end of the guardrail frame poles, and the guardrail tubes pass through and are fixed to the frame to form a guardrail. It also includes an anti-fall mechanism, which includes a U-shaped plate, a vertical plate, a magnetic plate, an outer plate, a vertical baffle, a metal mesh, a sleeve, a collar, an elastic rope, a handle, and a hanging plate. This technical solution, by setting an anti-fall mechanism at the guardrail frame, guardrail tubes, and base of the road and bridge guardrail, allows the metal mesh and outer plate of the anti-fall mechanism to form an L-shaped enclosure structure extending beyond the edge of the road and bridge outside the guardrail frame. However, the anti-fall mechanism cannot provide both lateral and longitudinal protection, affecting the protective effect of the device. Utility Model Content

[0005] To address the above problems, the purpose of this utility model is to provide a road and bridge guardrail that solves the problem that the anti-fall mechanism cannot form a combined effect of lateral and longitudinal protection, thus affecting the protective effect of the device. The guardrail is installed between adjacent guardrail uprights through a second frame to form a protective structure, serving as a second barrier for road and bridge protection. Furthermore, by forming a double-layer lateral barrier protection, and working together with the longitudinal protection formed by the stabilizing layer, guardrail uprights, and guardrail, the protective effect of the device is guaranteed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a road and bridge guardrail, comprising a base assembly, a railing assembly, and a stabilizing assembly.
