Description

Technical Field

[0001] The utility model belongs to the technical field of guardrails, and in particular relates to an isolation guardrail. Background Art

[0002] Isolation guardrails can be set up around some dangerous areas, such as rivers and cliffs. Setting up isolation guardrails of sufficient height and strength at the riverside can prevent pedestrians from accidentally falling into the water and play a role in protecting life safety. On some tourist roads in mountainous areas, if there are dangerous terrain such as cliffs, isolation guardrails can effectively prevent vehicles from rushing off the road due to loss of control and other reasons, thereby reducing the severity of accidents. However, after the existing isolation guardrails are fixed in position, they prevent pedestrians and others from approaching the dangerous area by themselves. The isolation height cannot be adjusted according to the actual range of protection required, and the isolation space is limited. Pedestrians and others can easily approach the isolation guardrail and still approach the dangerous area, which is not conducive to safe isolation work. Utility Model Content
