Guardrail for road construction

Abstract

The invention discloses a guardrail for highway construction, which comprises a main rod body, a magnet and a vortex spring. An adjusting rod is arranged inside the main rod body, and a strut is installed on the upper surface of the adjusting rod, and the strut is located on a groove rail. and the groove track is opened on the inner wall of the main rod body, the lower end of the main rod body is provided with an adjustment ring, and the upper surface of the adjustment ring is provided with a docking ring, and the adjustment ring is connected to the main rod body through the docking ring, the A vortex spring is provided on the outer surface of the lower end of the winding rod, and the vortex spring is located between the rewinding rod and the rewinding drum, and the rewinding rod is connected to the rewinding drum through the vortex spring. The guardrail for highway construction, the isolation curtain can be pulled out from the reel, which is convenient to adjust the specific enclosure range of the guardrail, which is beneficial to enclose the construction site according to the specific construction requirements, and the isolation curtain of the curtain-like structure can The construction site dust is isolated to avoid significant pollution of the surrounding environment of the construction site.

Description

technical field [0001] The invention relates to the technical field of road construction, in particular to a guardrail for road construction. Background technique [0002] In the process of road construction, it is often necessary to excavate it, so it is usually necessary to install guardrails around the road construction site for protection, to prevent pedestrians from entering the construction site by mistake, and to prevent pedestrians from being injured. There are generally the following problems in the use of guardrails; [0003] 1. It is inconvenient to adjust the protection length range of the guardrail, which is not conducive to enclosing the construction site according to specific needs, affecting the isolation of the road construction site, and at the same time, it is necessary to use more guardrails for protection under the premise of the same protection area, which improves the defense costs; [0004] 2. It is not conducive to the isolation and protection of d...
