Efficient dredging planning method and device for urban drainage pipe network and medium

The invention relates to an efficient dredging planning method and device for an urban drainage pipe network and a storage medium, and the planning method comprises the steps: constructing an SWMM urban pipe network model, and correcting the SWMM urban pipe network model based on an actual measurement pipe network discharge port flow process; simulating and calculating the flow velocity of each pipeline through the SWMM urban pipe network model, and determining the distribution rule of pipe network sedimentation; on the basis of the pipe network drainage capacity under different sedimentation working conditions, a relation curve of the global sedimentation coefficient and the pipe network drainage capacity is constructed, and the optimal dredging moment is determined; calling a dynamic link library generated on the basis of a VISUAL STUDIO platform, and starting a calculation engine of the SWMM model; and by taking the urban pipe network siltation working condition corresponding to the optimal dredging moment
