The wave guardrail plate is a safety facility. Generally , the maintenance of the wave guardrail board mainly includes replacement and cleaning :

(1) When the highway guardrail is damaged by collision, in order to ensure that the passing vehicles can pass safely, we need to use construction machinery and materials to repair the damaged waveform guardrail in time, restore the original protection function of the wave guardrail, and eliminate hidden safety hazards to provide a good guarantee for road safety. From the maintenance, it was found that during the construction of the project, when the wave guardrail and the communication and monitoring pipelines are located on both sides of the highway or the central separation zone, the connection work of the two projects should be specially done to avoid the buried pipeline when installing the wave guardrail column Breaking, affecting the installation of pipelines.

(2) For the beauty of highway guardrails, we also need to regularly clean and maintain the corrugated guardrails. Due to the high labor intensity and low work efficiency of manual cleaning of wave guardrails, it also poses a threat to the safety of maintenance workers. Currently, special vehicle improvement equipment is generally used for weekly cleaning and maintenance.
