Description

Technical Field

[0001] The utility model belongs to the technical field of temporary guardrails, and in particular relates to a temporary guardrail structure used for highway maintenance. Background Art

[0002] Temporary guardrails for highway maintenance, also known as temporary guardrails for road construction, are a type of safety protection equipment used in road construction areas. During the construction, maintenance, and repair of highways, the construction area needs to be separated from the driving lane to ensure the safety of construction workers and drivers. This type of temporary guardrail usually plays an important role and can effectively separate the construction area and the driving area, avoiding the spillage of hazardous materials at the construction site and damage to vehicles caused by mechanical equipment.

[0003] The temporary guardrails for highway maintenance currently on the market have the following problems when used:

[0004] 1. In the actual use of traditional temporary guardrails for road maintenance, pulleys are usually installed at the bottom to facilitate the movement of temporary guardrails. However, after the pulleys are installed, the convenience of movement is increased, but the stability during use is reduced. Once it is hit or blown by strong winds, it is easy to shake and move. Therefore, it is not possible to achieve both stability and ease of movement during use, and it is not convenient to use;

[0005] 2. When most temporary guardrails are used for highway maintenance, construction workers often mark words on the outside of the temporary guardrails. However, due to the weak light when driving at night, pedestrians and drivers cannot observe the construction section well. Therefore, the warning effect is weak when used at night.
