The invention relates to an energy-saving and high-efficiency self-reactive multidirectional mixing pile forming device which comprises a base, a power box, a power head and a drill bit. A pylon and a windlass are arranged on the base. A pulley block is arranged at the top of the pylon. The windlass is connected with the power box by means of a steel wire rope bypassing the pulley block. The power head is mounted in the power box. Multidirectional and multiple mixing is realized by means of one power head and the structure of the machine, high-efficiency and high-quality mixing pile forming can be realized through one-time drilling, energy consumption is reduced, the construction cost is reduced, hard formations can be effectively penetrated, and the multidirectional mixing pile forming device is widely applied to different formations.
