The invention discloses a removable hanging pile bracket for construction of a hanging pile of a steel casing of a cofferdam, which comprises a central plate and a plurality of support legs. The central plate comprises a central sleeve, an upper end plate and a lower end plate, wherein the upper end plate and the lower end plate are welded on the peripheral surfaces of the upper end and the lower end of the central sleeve; and the support legs are respectively and uniformly arranged between the upper end plate and the lower end plate along the periphery of the central plate and are respectively hinged with the upper end plate and the lower end plate. When the removable hanging pile bracket is in the hanging state, the central plate is rotated to the position where the support plates are aligned at reserved holes in the steel casing, the support legs are pulled out from the reserved holes and are fastened to the central plate through bolts after adjustment and positioning, and construction can be carried out after the removable hanging pile bracket is installed. When the construction is completed, the bolts are removed, the bracket can be used in an inverted way, the efficiency of hanging pile construction can be increased, and the construction cost can be reduced.
