General structure and function of highway wave guardrail

Movable guardrail-refers to the movable guardrail set at the opening of the central partition to facilitate the emergency passage of accident handling vehicles and emergency rescue vehicles. Today, plug-in guardrails are more commonly used.

Any guardrail installed on a bridge is called a bridge guardrail, even if it is a guardrail in the same form as a road section, it is also called a bridge guardrail. Its main performance should be that vehicles cannot break through, underpass or overtake bridges.

Standard section of corrugated guardrail board-refers to the part of the structure where the cross-sectional structure of the guardrail remains unchanged and is set normally. The setting of the standard guardrail section should be consistent with the road geometry.

The end of the roadside wave guardrail refers to the special structure set at the beginning or end of the roadside guardrail. Its main performance is to absorb collision energy, has a guiding function, and is easy to maintain.

The end of the central partition fence-refers to the special structure set at the beginning or end of the central partition fence, including the end of the opening of the central partition fence. Due to different guardrail structures, there are many types of guardrail ends of the central partition. The end should have an energy-absorbing effect, and be guided and easy to maintain.

Wave guardrail transition section-refers to a special structural section that can smoothly connect guardrails of different structural forms and perform rigidity transition. The transition part is mainly used where the corrugated beam guardrail is connected to the bridge concrete guardrail. The guardrails of two different structures should not be disconnected at the bridge head connection, nor should they be directly connected without reinforcement.

The gradually changing part of the wave guardrail refers to the part of the guardrail structure set between the mobile end and the standard part to connect and smoothly transition the outreach line. The transition section is mainly used at the beginning of the roadside guardrail, which is used for kidnapping at the emergency telephone opening of the roadside guardrail, while the transition section of the guardrail is used at the opening of the central partition, usually called a parabola.
