(3) Combination of powder sprayed pile foundation treatment technology and CFG pile foundation treatment technology. The main purpose of combining the powder sprayed pile foundation treatment technology and CFG pile foundation treatment technology is to use the consolidation ability of the powder sprayed pile and CFG pile to combine the soil of the foundation to form a satisfactory foundation. Not only can the bearing capacity of CFG piles be brought into full play, but also the restraint capacity of powder sprayed piles can be greatly increased due to the embedding of CFG piles. Although the traditional foundation treatment technology analyzed above is still adopted on a large scale in the current construction field, with the development of modern buildings, the requirements for foundation construction are getting higher and higher, and the traditional foundation treatment technology can no longer reach the building The need for foundations.
