[0002] In the construction of transportation infrastructure such as roads and bridges, the crash barrier plays a crucial role in safety protection. During the construction of the crash barrier, especially after the concrete is poured, a large amount of sundries and garbage often remain at the bottom of the back wall. Over time, various garbage and sundries tend to accumulate at the bottom of the back wall of the crash barrier. These garbage may come from dust, leaves, small branches, etc. brought by wind and rain washing in the natural environment, or may be items left by passing vehicles, such as plastic bottles, food packaging bags, etc.

[0003] At present, there are many difficulties in cleaning the garbage at the bottom of the back wall of the crash barrier. Due to the existence of the crash barrier, conventional cleaning equipment is difficult to reach the narrow space at the bottom of the back wall for effective cleaning. Manual cleaning not only has a high labor intensity, but also has low efficiency and certain safety risks, especially on roads with heavy traffic. In addition, the garbage that is not cleaned in time will also affect the beauty of the road and cause pollution to the surrounding environment, which does not meet the requirements of modern transportation construction for environmental cleanliness; therefore, in order to solve the problem of cleaning the garbage at the bottom of the back wall of the crash barrier, a special garbage cleaning device is urgently needed, which can efficiently and safely clean the garbage at the bottom of the back wall and ensure the normal use of the crash barrier and the cleanliness of the road environment.
