[0002] High-pressure jet grouting is a commonly used pile foundation construction method. It uses a high-pressure rotating nozzle to spray cement slurry into the soil layer and mix it with the soil to form a continuous overlapping cement reinforcement body. Its working principle mainly includes pile driver installation, hole drilling, introduction of steel cage and soil treatment. Among them, soil treatment is to install a jet grouting device in the hole, use the rotating jet of high-pressure water and cement slurry to treat the surrounding soil into a suspension, and then form a jet grouting pile.
[0003] The rotary spraying device is usually inserted into the bottom side of the hole through a rod, and then rotated upward to perform rotary spraying.
