The invention relates to the technical field of pile foundation construction, in particular to an underwater pile connecting column construction method which comprises the following steps: S1, pile foundation construction; s2, pile top desilting; s3, coring the pile head; s4, pier column steel bars are installed; s5, pier column forming; s6, pile casing separation and formwork removal; and S7, pier body maintenance. According to the construction method of the underwater pile connecting column, in the pile forming process, the pile casing arranged in the pile foundation forming process is adopted to replace a cofferdam, the cofferdam construction cost is reduced, the material consumption is reduced, the construction cost is reduced, meanwhile, manual operation is adopted to enter the pile casing for pile head coring, the mechanical property of the pile casing is good, the safety risk in construction is low, and the construction efficiency is improved. The construction efficiency is high, the occupied space of
