The invention relates to the technical field of piling mechanism and discloses a deep-hole spiral pile hammer. The deep-hole spiral pile hammer comprises a stand, a drill stem bracket and a drill stem component, the drill stem bracket is provided with a slide rail, the drill stem component is connected with the slide rail in a sliding mode, the stand is further provided with a winch for driving the drill stem component to lift, the drill stem component comprises a drill stem and a drill arranged at the lower end of the drill stem, a main spiral blade is arranged at the outer side of the drill stem, an auxiliary spiral blade is arranged at the outer side of the drill stem, the spiral direction of the auxiliary spiral blade is the same with the spiral direction of the main spiral blade, the outer diameter of the auxiliary spiral blade is smaller than the outer diameter of the main spiral blade, saw tooth blades are arranged at the edges of the main spiral blade and the auxiliary spiral blade, a motor bracket is arranged at the upper end of the drill stem, a motor and a speed reducer are arranged in the motor bracket, and the upper end of the drill stem is coaxially connected with the output shaft of a speed reducer. The deep-hole spiral pile hammer is capable of effectively lowering the drill stem pulling resistance, improving the piling efficiency, reducing the load of a drive motor in the winch and improving the service life of the winch.
