Abstract： Through the analysis of the hidden culverts and their silt distribution characteristics of the hidden culverts such as PingtaCreek， HougangCreek， GuxiCreek and HoushanCreek in Ningde City， as well as the advantages， disadvantages and applicability of robot dredging， loader dredging， mobile suction pump dredging， hydraulic flushing and manual dredging， etc.， different ways and methods of silt removal in culverts are summarized in order to provide experience for similar projects in the future and provide support for the compilation of construction codes for silt removal in culverts.

Keywords： black smelly culvert; robot dredging; loader dredging; mobile suction pump dredging; hydraulic washing dredging; manual dredging

随着城市化进程的不断加速，宁德城区人口日益密集;由于宁德水资源时空分布不均，城区水环境承载力有限，加上城市基础设施建设进度相对滞后，宁德城区水环境问题日益突出，部分暗涵长期处于黑暗、密闭的状态下，污水排入暗涵后容易厌氧发臭，形成黑臭水体[1]，城区内河河网黑臭问题日益凸显。（剩余5105字）
