METHOD FOR PREPARING SOLIDIFIED TREATED PILE

摘要

PROBLEM TO BE SOLVED: To provide a method for preparing a solidified treated pile capable of realizing the smooth execution of works even when a solidified pile is prepared up to an underground depth such as the preparation of a long-sized solidified pile and the preparation of a splicing-driven solidified pile. SOLUTION: In the method in which a solidifying material is discharged into a ground in the rotating regions of one or more of agitating blades 2 and 2 radially installed to the lower sections of rotating shafts 1 and 1 from solidifying-material discharge pipe ports 31 annexed at the fixed places of the rotating shafts 1 and 1 and agitated and mixed with in-situ soil and the solidified treated pile Z is prepared, the solidifying material is discharged to the lower section Y of a solidified-treated pile preparation region in a penetration process, and discharged to a residual upper section X in the second penetration process after a pull-out.
