Abstract: This article describes the mechanism of post-grouting combination as well as the design of grouting device for pile’s side and bottom. Besides, the article also introduces the handling process and operation guidelines for the technology. Finally, according to the testing data analysis of the bearing capacity experiment, we could provide the addtional coefficient of bearing capacity that is suitable for this project. Meanwhile, it is also a significant milestone of offering the valuable reference to the similar projects in the future.

Keywords: post-grouting; slurry drilled pile; bearing capacity
