Description

Technical Field

[0001] The utility model relates to the technical field of bridge maintenance, in particular to a road bridge maintenance device. Background Art

[0002] The primary function of road and bridge guardrails is to prevent vehicles from falling off the road in the event of a traffic accident. However, due to long-term exposure to the sun, rain, and various dust and other compounds, guardrails are prone to oxidation, which significantly reduces their protective capabilities. In the event of a traffic accident, guardrails often fail to fully perform their intended functions of preventing vehicles from falling and providing a significant cushioning effect.

[0003] Guardrail surfaces are susceptible to varying degrees of contamination due to vehicle exhaust, dust adhesion, and other environmental factors. Therefore, guardrails require frequent cleaning. Currently, domestic guardrail cleaning is primarily performed manually, which is not only labor-intensive but also inefficient. While there are also methods for cleaning and maintaining guardrails using cleaning vehicles, existing cleaning vehicles primarily rely on large quantities of clean water for flushing and fail to recycle water resources, resulting in significant water waste. In light of this, in-depth research into the aforementioned issues led to the present case. Utility Model Content
