[0002] The space under the steel guardrail in the median strip of large highway bridges is small, which is very easy to accumulate dust, sand and other garbage. Since this location belongs to the median strip, ordinary road sweepers can only clean the driving lane and cannot sweep the median strip, making it easy for garbage to accumulate in the space below the steel guardrail. When there is too much garbage here or affected by wind, the garbage will move to the driving lane, which may affect normal driving safety. At the same time, since most steel guardrails are rectangular guardrails, garbage may accumulate around the bottom of the guardrail column, making it inconvenient to clean.

[0003] The traditional cleaning method for the space under the steel guardrail of the highway bridge is to first manually control the traffic and seal off the fast lane, and then clean it manually. However, it is very dangerous to control the traffic on the highway and perform manual cleaning operations. At the same time, the cleaning efficiency is low, the cost is very high, and the safety and economy are poor.
