Pile-forming equipment for mixed alternate multi-spraying multi-layer reverse cement-soil stirring stiffness core composite pile

The mixed alternate multi-spraying multi-layer reverse cement-soil mixing stiffening core composite pile forming equipment comprises a supporting frame, stiffening core composite pile mounting plates are connected to the two sides of the supporting frame through pull ropes, mounting limiting plates are fixedly connected to the bottom ends of the stiffening core composite pile mounting plates, and fixing mechanisms are arranged in the stiffening core composite pile mounting plates; the device has the beneficial effects that a pile inserting power device of a stiffening core pipe pile square pile or a pile forming power device of an outer core dry and wet cement soil mixing pile is installed on the two sides of the supporting frame, so that the two devices can work at the same time, and the time efficiency is improved; and meanwhile, the pile forming quality of the outer core pile is greatly improved by using the mixed alternate multi-spraying and multi-layer reverse cement-soil mixing pile forming equipment an
