[0002] Soft soil foundations are often distributed along the coast and in river basins of my country. Improper treatment of soft soil foundations will lead to serious foundation settlement, affecting the safe operation of highways and railways. Among the various methods for treating soft soil foundations, the most commonly used is grouting pile composite foundation reinforcement. Grouting piles use special mechanical equipment to send cement slurry into the ground, and force the cement slurry and the in-situ foundation soil to mix, so that a series of physical-chemical reactions quickly occur between the foundation soil and the reinforcement material. In a short period of time, the slurry forms a solid column, turning the soft soil foundation into a reinforced soil pile composite foundation with integrity, water stability and a certain strength.

[0003] In the related art, a unidirectional mixing pile machine is commonly used in construction. Announcement No.: CN 217840003U discloses a bidirectional mixing paddle pile spraying machine.
