Multi-axis multi-direction air spraying cement soil stirring pile machine and single-axis multi-direction cement soil stirring pile machine

The invention discloses a multi-axis multi-direction air spraying cement soil stirring pile machine. The multi-axis multi-direction air spraying cement soil stirring pile machine comprises a pile frame, N first drill rod drill bit devices and N+1 or N+2 second drill rod drill bit devices, wherein N is larger than or equal to 1. The first drill rod drill bit devices and the second drill rod drill bit devices are spaced in parallel, each first drill rod drill bit device is located between a pair of adjacent second drill rod drill bit devices, each first drill rod drill bit is in unified steering linkage with a pair of corresponding rotating cylinders through a gear set, a first stirring piece on each first drill rod drill bit, second stirring pieces on the pair of corresponding second drill rod drill bits and third stirring pieces on the pair of corresponding rotating cylinders partly coincide in the work feeding direction of the cement soil stirring pile machine. Meanwhile, the invention provides a single-axis
