Description

Technical Field

[0001] The utility model relates to the technical field of convenient replacement, in particular to a road guardrail. Background Art

[0002] As a traffic safety facility, road guardrails play a vital role in the modern transportation system. Road guardrails are facilities installed on both sides or in the middle of the road to separate vehicles and pedestrians and protect the safety of traffic participants. Road guardrails separate the carriageway from the pedestrian area to prevent pedestrians from mistakenly entering the lane and reduce the risk of traffic accidents. At the same time, guardrails can also prevent vehicles from deviating from the lane and guide vehicles to drive in the specified lane. Setting guardrails along the road can reduce direct collisions between vehicles and pedestrians and reduce the degree of injury caused by accidents. Road guardrails can provide guidance functions through elements such as their shape, color and signs to help drivers determine the direction and direction of the road. By selecting appropriate materials and designs, road guardrails can increase the overall beauty of urban roads and enhance the image of the city.

[0003] Compared with the existing technology: the existing road guardrails are not convenient to replace themselves, which may increase safety hazards. If the damaged guardrails are not replaced in time, the damaged areas may further deteriorate, affecting the overall protection capabilities. Pedestrians or vehicles may cross the road from the damaged areas, causing a direct impact on traffic safety and increasing the risk of traffic accidents. Especially on busy roads or highways, the absence or damage of guardrails may lead to more serious consequences.

[0004] Therefore, a road guardrail is proposed. Utility Model Content
