Segmented staged installation method for unloading plate of bulk cargo ship

The invention provides a bulk cargo ship unloading plate segmented stage installation method, and relates to the technical field of bulk cargo ships, and the method comprises the following steps: (1) an initial stage: setting segmented division positions, and dividing partial segmented groove-shaped wall plates and unloading plates of a groove-shaped bulkhead into bottom segments; (2) a segmentation stage: pre-splicing the segmented groove-shaped wall plates at the bottom and the segmented groove-shaped wall plates of the groove-shaped bulkhead; the plates formed through pre-splicing are subjected to unified overall profiling, and overall assembling is conducted after profiling; after profiling and assembling are completed, the segmented groove-shaped wall plates at the bottom and the segmented groove-shaped wall plates of the groove-shaped bulkhead are detached; after the bottom segmented groove-shaped wall plates are installed on the bottom piers on the horizontal jig frame, unloading plates are installed,
