Abstract

The invention relates to the technical field of highway protecting facilities and discloses a guardrail. The guardrail is used for protection of a highway construction area and a central dividing strip opening and has good movable convenience and protective safety. The guardrail comprises at least two fixed sections. Each fixed section comprises a fixed base and a first beam arranged on the fixed base. Each fixed base is fixedly connected with a to-be-stored area and is connected with a plurality movable sections between every two fixed sections. Each movable section comprises a movable base and a second beam arranged on the movable base. The movable bases are detachably connected with the fixed bases, and every two adjacent movable bases are detachably connected. The second beams are detachably connected with the first beams, and the every two adjacent second beams are detachably connected.

Description

technical field [0001] The invention relates to the technical field of road protection facilities, in particular to a guardrail. Background technique [0002] Reconstruction and expansion projects and maintenance of highways are usually carried out without interrupting the traffic. For the convenience of construction, when the construction area occupies the driving lane, passing vehicles often need to be forced to slow down and change lanes within the range of this road section, and keep passing slowly at a low speed. Construction road section, within the scope of this road section, traffic accidents are often caused by collisions between passing vehicles and personnel or equipment in the construction area due to vehicle loss of control or other reasons. At present, isolation facilities such as traffic cones, anti-collision barrels or isolation piers are usually placed outside the highway construction operation area to isolate the construction operation area. The vehicle is...
