[0002] With the rapid development of bridge construction, the safety issues in the bridge construction process have received increasing attention. During the bridge construction process, guardrails, as important safety facilities, not only play a role in preventing people or objects from accidentally falling, but also effectively guide the traffic flow at the construction site.

[0003] However, most traditional bridge construction guardrails are fixed, difficult to install and remove, and not conducive to flexible adjustment of the construction site; at the same time, traditional guardrails often lack sufficient buffering and protection when impacted, making it difficult to effectively protect the safety of construction workers. In addition, the environment of bridge construction sites is complex and changeable, and traditional guardrails often lack sufficient lighting and reflective signs, which poses a greater safety hazard during nighttime construction.

[0004] For example, Chinese patent CN114856306A discloses a guardrail for municipal road and bridge construction, which includes a placement plate, a handle, a first connecting block, a folding frame and a guide block, etc. A handle is provided in the middle of the top of the placement plate for pushing the guardrail for municipal road and bridge construction to move, two first connecting blocks are slidably provided on the left and right sides of the placement plate, a folding frame is rotatably provided between the first connecting blocks on the same side in the longitudinal direction, and three guide blocks are slidably provided on the folding frame at intervals; it is easy to move, but its anti-collision effect is poor, and it is inconvenient to disassemble and assemble.

[0037] When the guardrail is impacted, the piston assembly can slide in the sleeve 3 and compress the elastic member 6, while driving the slider 5 to slide in the slide groove, thereby absorbing and dispersing the impact force, so that the guardrail can produce a certain deformation when impacted, effectively reducing the impact of the impact force on the structure, improving the impact resistance of the guardrail, and thus improving the safety performance during the bridge construction process;

[0038] The two adjacent guardrails in the utility model can be conveniently assembled and disassembled through the connecting assembly, and the number of assembled guardrails can be adjusted according to the specific use environment of the bridge construction.
