[0003] During the construction process, in order to increase the speed of installation and disassembly and facilitate workers to carry the construction guardrail, universal wheels are usually installed on the construction guardrail. However, during the construction process, a certain amount of dust will be generated in the guardrail equipped with universal wheels, which will overflow through the gaps of the universal wheels and pollute the airport runway. It is very troublesome to clean up, causing the runway to be closed for a long time.
