[0002] The isolation guardrail for bridge roads is a facility installed on both sides of road bridges. Its main function is to separate roads, prevent pedestrians and vehicles from crossing at will, and ensure traffic order and safety.

[0003] Existing isolation guardrails used for bridges and roads are usually difficult to install, have a short service life, and occupy a large space. Since isolation guardrails are usually welded metal pipes as isolation components, they need to be laid one by one for lateral isolation protection. The length of a single isolation guardrail is not adjustable and cannot be stretched to different lengths according to needs. At the same time, it is not easy to replace a single isolation guardrail after it is damaged. Therefore, we need to propose a non-isolation guardrail for bridges and roads. Utility Model Content
