Abstract: According to construction experience and comparison between castinsitu concrete pile and soilcement pile mixed by triaxial stirring machine, the process of the combination of positive and negative cycle is determined, and the weathering rock drilling technology is guaranteed by improving the drill head structure of triaxial stirring machine. The construction parameters of castinsitu concrete pile and soilcement pile mixed by trixial stirring machine are gain in basic of actual construction. The paper can provide reference for similar projects in the future.

Key words: water rich, super thick, castinsitu concrete pile, soilcement pile mixed by triaxial stirring machine, rock drilling technology
