Description

Technical Field

[0001] The utility model relates to the technical field of temporary guardrails, and more specifically to a combined temporary guardrail for highway construction. Background Art

[0002] When a part of the highway road surface is damaged, it needs to be repaired in time. In order to ensure the safety of the construction site, temporary guardrails are usually placed outside the construction site.

[0003] After searching, the utility model patent with announcement number CN213597671U discloses a combined guardrail for highway construction, including a combined guard plate, a card interface is provided on one side of the combined guard plate, a card adapter block is fixedly connected to the other side of the combined guard plate, a fixed base is carded at the bottom of the combined guard plate, a connecting rod is fixedly connected to the inner wall of the card interface, a rotating bearing is fixedly connected to the top of the connecting rod, a warning light is fixedly connected to the top of the rotating bearing, and a striking target is fixedly connected to the front of the combined guard plate, and there are multiple striking targets; this patent increases the ground contact area and the bottom center of gravity of the fixed base by setting a fixed base and universal wheels, and the fixed base is trapezoidal and made of. The guardrail can be easily moved by the universal wheels, and the fixed base makes the bottom of the guardrail more stable and not easy to fall down.

[0004] However, the above patent still has the following shortcomings: when multiple universal wheels need to move up and down, multiple cranks need to be turned to operate, which is not convenient. Although the trapezoidal base can ensure the stability of the guardrail to a certain extent, there is a possibility of accidental collision of vehicles when the guardrail is used during highway construction, and the construction site cannot be well protected. For this reason, we propose a combined temporary guardrail for highway construction. Utility Model Content
