description The utility model relates to the technical field of open caisson repair, in particular to an open caisson damage repair device which comprises a steel pipe column, an overturning bottom die and a prestress tensioning mechanism, and the steel pipe column is used for being arranged in a well hole with a damaged well wall in an open caisson structure; the overturning bottom die is used for being arranged on the steel pipe column in a sleeving mode, can be lowered to the position below the bottom of the damaged position of the well wall of the well hole along with the steel pipe column and can be opened to support concrete poured between the steel pipe column and the well wall. The prestress tensioning mechanism is used for connecting the well wall and the steel pipe column and adjusting the pretightening force between the well wall and the steel pipe column at the top of the steel pipe column. The problems that in the prior art, no open caisson damage repairing method exists, but the bearing capacity and durabil
