The utility model belongs to the technical field of drilling equipment, and particularly relates to a combined hydraulic square pile drill bit. According to the specific technical scheme, the machine box comprises a drill bit module and a machine box body with a downward opening, the drill bit module comprises a power box component and digging components, the digging components are coaxially arranged on the two sides of the power box component, and the power box component drives the two digging components to rotate; two mounting plates are arranged in the case body at intervals, and the upper portion of the power box component is connected with the two mounting plates and located between the two mounting plates. When large-size square pile construction operation is carried out, the multiple drill bit modules can be installed on the machine box body, the axis directions of excavating components of the multiple drill bit modules are parallel pairwise, and on the premise that the excavating capacity of square pi
