[0002] In order to quickly drain the water on the bridge surface and prevent rainwater from stagnating on the bridge deck and seeping into the beam body to affect the durability of the bridge, in the design of the bridge, in addition to setting up longitudinal and transverse slope drainage on the bridge deck, a certain number of drainage pipes are needed on the bridge deck to form a complete drainage system. The types of drainage pipes generally include metal drainage pipes, reinforced concrete drainage pipes, transverse drainage pipes, etc. The bridge deck drainage system should be set up with longitudinal and transverse slopes and drainage holes on the bridge deck to reduce the water on the bridge surface and achieve the purpose of combining prevention and drainage.

[0003] The sewer pipes on the bridge deck may be blocked due to mud, especially the ends of the sewer pipes, which are easily blocked by mud, straw and other debris. In this case, the mud needs to be cleaned. However, when cleaning the existing sewer pipes, sanitation workers usually use wooden sticks to guide the mud, which causes the mud to fall and cause blockage at the bottom of the sewer pipe again, making it impossible to effectively clean the pipes.
