New Grade Classification for Corrugated Guardrails
Classification of Waveform Guardrails: Waveform beam guardrails are generally classified based on their installation location and anti-collision level. According to the setting location, it can be divided into roadside guardrails and central divider guardrails. It can be divided into A-level and S-level according to the collision prevention level. S-grade guardrails are reinforced and suitable for use on particularly dangerous road sections, while A-grade guardrails are used on dedicated highways
Waveform beam guardrail is the main form of semi-rigid guardrail, which is a continuous structure composed of corrugated steel guardrail plates that are spliced together and supported by the main column. It utilizes the deformation of soil foundations, pillars, and crossbeams to absorb collision energy and force out of control vehicles to change direction, return to normal driving direction, prevent vehicles from rushing out of the road, protect vehicles and passengers, and reduce losses caused by accidents. The waveform beam guardrail combines rigidity and flexibility, with strong absorption of collision energy and collision prevention ability. It has good line of sight guidance function, can coordinate with the road shape, and has a beautiful and coordinated appearance. It can be used on small radius bends, and is easy to replace damaged areas. Composite waveform beam guardrails can be used on narrow central dividing strips.
For sections where vehicles may cross the road (bridge) and cause serious consequences, it is possible to choose to strengthen the waveform beam guardrail. The utility model of a waveform guardrail relates to a composite waveform plate movable steel guardrail used at the opening of a central divider strip on a highway. The guardrail is composed of two waveform steel guardrail plates and two columns fixed and clamped between them. The two columns are fixed and clamped between the two waveform steel guardrail plates.
During normal operation on highways, this guardrail can be easily inserted into the pre-set insertion and extraction holes at the opening using plug-in columns, providing isolation and protection. At the same time, it echoes the guardrail belt on the outside of the highway, neat and uniform, and aesthetically matched. When a vehicle collides with it, due to the good crash resistance and energy absorption function of the corrugated steel guardrail plate, it is not easy to be damaged and can also provide good protection for the vehicle and passengers. When road maintenance or other reasons require parallel access, it is convenient to pull out and remove the various guardrail pillars at the opening, open up a passage, and facilitate vehicle passage.
