During the installation of high municipal guardrails, the layout is based on the embankment height, slope gradient, and condition of the objects being maintained. The overall protection provided by the guardrails, along with the correct vehicle guidance, serves as a functional conclusion for ensuring the safety of passengers inside the colliding vehicle. Prior to installation, it is essential to familiarize oneself with the road and bridge design along the route and give it due consideration.

Typically, concrete wall-style guardrails are used on large and medium-sized bridges. When connecting to road guardrails, there is a process of transition from rigid to flexible, which should be paid close attention to. At this point, the road should adopt a reinforced type and be securely connected to the wall-style guardrails. To avoid the impact of bridge expansion joints, an additional section of wall-style guardrail can be installed on the bridge deck. Moreover, at urgent phone locations along the roadside guardrails, both an opening and proper maintenance of the phone equipment should be considered, warranting special consideration.

In areas where high retaining walls are being constructed, it is essential to consider the stability of the foundation for guardrail posts. For safety reasons, it may be advisable to opt for a wall-type guardrail; guardrails should also be installed within tunnels and properly connected to those outside. When the curve radius is less than 70 meters, standard guardrail panels (each 4 meters in length) are no longer applicable, and customized bend beams must be used. The design should calculate the number of bend beams individually based on different radii.
