During the installation of high road guardrails, the layout is based on factors such as embankment height, slope gradient, and the condition of the protected objects. The guardrails provide comprehensive protection and ensure the correct guidance of vehicles, guaranteeing the safety of passengers inside the colliding vehicles.
Prior to installation, familiarize yourself with the route and bridge design along the line, and take them into consideration.
2. Typically, concrete wall-style guardrails are used on large and medium-sized bridges, and there is a transition process from rigid to flexible when connecting them to road guardrails, which should be given due attention. The road should adopt a reinforced type and be securely connected to the wall-style guardrails. To avoid the impact of the bridge expansion joints, an additional section of wall-style guardrails can be installed on the bridge abutment.
3. Additionally, at emergency phone locations along the roadside barriers, both openings should be set and special consideration should be given to adequately protect the phone facilities.
4. When constructing high retaining walls, consider the stability of the foundation for the guardrail posts.
5. For safety reasons, wall-mounted guardrails can be installed instead.
