Description

Technical Field

[0001] The utility model belongs to the technical field of highway engineering, and more specifically, it particularly relates to a highway guardrail. Background Art

[0002] As an important passage connecting various regions, in order to ensure the smoothness of traffic, guardrails need to be installed on the highway. The guardrails are divided into the outer guardrail of the highway lane and the central divider guardrail. The outer guardrail of the lane mainly protects the outside of the highway or diverts motor vehicles and non-motor vehicles, ensuring the safety of highway traffic.

[0003] According to CN202420185063.8, the present utility model provides a highway guardrail, which relates to the technical field of guardrails, including a guardrail main body. Fixed columns are arranged on opposite sides of the guardrail main body. The guardrail main body and the two fixed columns are respectively connected by a plurality of fixing devices. The plurality of fixing devices are respectively movably arranged in mounting grooves provided on the fixed columns. Limiting devices for limiting the fixing devices are arranged on opposite sides of the two fixed columns. Pull the limiting rod in a direction away from the fixed block. When the opposite ends of the guardrail main body completely enter the interior of the mounting groove, at this time, release the limiting rod. Through the elastic force of the limiting disc fixedly penetrated through one side of the limiting rod and the elastic member, the limiting rod enters the interior of the guardrail main body. By setting the limiting rod, the elastic member and the limiting disc, the device realizes a certain supporting effect on the opposite ends of the guardrail main body during installation, eliminating the need for manual support, with a simple structure and easy operation, making the installation of the guardrail main body more convenient.

[0004] Based on the above, existing guardrails generally support the guardrail frame through a support rod structure. When the guardrail is set on the outside of the highway to separate motor vehicles and non-motor vehicles, since the height of the separating guardrail is relatively low and the upper side of the guardrail is flat, it is easy for people to climb over the guardrail. When there are vehicles driving on the highway, if a staff member climbs over the guardrail by accident, it is easy to cause harm to the personnel. Summary of the Utility Model
