Also provided is an open caisson construction method. A guide member is formed by the cast-in-place piles (1), the steel pipe columns (2), and the steel corbels (8) when the open caisson (7) is sunk, and the height of the pipe section column (6) is adjusted by the jack (5), so as to ensure that the open caisson (7) always maintains a vertical state during the process of being being sunk.
