Guardrail for highway construction

Abstract

The invention discloses a guardrail for highway construction. The guardrail comprises a main rod body, a magnet and a vortex spring. An adjusting rod is arranged in the main rod body; a supporting rodis mounted on the upper end surface of the adjusting rod; the supporting rod is positioned on the inner side of a grooved rail; the grooved rail is arranged on the inner wall of the main rod body; anadjusting ring is arranged at the lower end of the main rod body, a butt joint ring is arranged on the upper surface of the adjusting ring, the adjusting ring is connected with the main rod body through the butt joint ring, the vortex spring is arranged on the outer surface of the lower end of a winding rod, the vortex spring is located between the winding rod and a winding barrel, and the winding rod is connected with the winding barrel through the vortex spring. According to the guardrail for highway construction, an isolation curtain can be drawn out of the winding barrel, the specific enclosure range of the guardrail can be adjusted conveniently, so that enclosure of a construction site is facilitated according to specific construction requirements; meanwhile, the isolation curtain ofa curtain-shaped structure can isolate dust of the construction site, so that the surrounding environment of the construction site is prevented from being polluted greatly.

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...

Problems solved by technology

[0006] The purpose of the present invention is to provide a guardrail for road construction, to solve the inconvenient adjustment of the protective length range of the guardrail proposed by the above background technology, 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 Under the premise of the same protection area, more guardrails need to be used for protection, which increases the protection cost and is not conducive to the isolation and protection of dust to a certain extent. It is transported and transferred, and the problem of occupying a large space at the same time
