Summary:The utility model discloses a steel cofferdam sinking guide device which comprises a steel casing and a steel cofferdam arranged on the structural periphery of the steel casing. A guide limiting steel pipe is arranged between the steel casing and the steel cofferdam. Due to the adoption of the structure, the steel cofferdam sinking guide device has the following advantages that the guide stiffness of the steel cofferdam is improved; the deviation resistance of the steel cofferdam is improved; the accuracy of positioning the sinking of the steel cofferdam is ensured; and the steel cofferdam sinking guide device is particularly suitable for sinking the steel cofferdam under the complex hydrologic conditions such as in a strong tidal bore region. An inserted steel pipe pile is used as a limiting guide part, so that the guide stiffness of the steel cofferdam in the sinking process is improved and the deviation resistance of the steel cofferdam or an open caisson under the complex hydrologic conditions is improved
