The invention discloses a method for wrapping a concrete caisson with a corrosion resisting metal material. The method comprises the steps that an outer side template of concrete is used as a supporting structure, double-screw bolts and nuts are adopted as fixing and anchoring components, surface wrapping of the large-area plane concrete structure is achieved, and compared with other outer wrapping technologies, a molded concrete structure does not need to be punched, and damage to the concrete structure in the outer wrapping process is avoided.
