This application relates to a flood control emergency response method, device, and electronic equipment for a valley-type dry ash storage yard. The method includes: responding to a preset emergency condition where the water level of the downstream drainage well's tail-end dammed lake meets the required emergency conditions, initiating emergency drainage measures to excavate a flood discharge channel and construct a flood control work surface; using a combination of hydraulic flushing and slurry pumping to clean the surrounding sediment deposits of the upstream drainage well; and after the drainage functions of both the downstream and upstream drainage wells are restored, reshaping the ash surface morphology of the entire valley-type dry ash storage yard based on the flood control work surface to construct a flood discharge system with the drainage wells as the lowest control points within the yard. This solves the problems in related technologies where heavy rain causes drainage wells to be buried by sediment, leading to drainage system failure, rapid rise in water level within the storage yard, and a lack of systematic emergency response measures, resulting in a sharp shortening or even disappearance of the dry beach in front of the dam, posing a risk of ash water overflow and dam collapse.
