Abstract

PURPOSE: To form a large-diameter soil cement column with ease by rotating a plurality of rotary vertical shafts and the group of the rotary vertical shafts respectively in a rotating casing while rotating or shaking the whole of them and by jetting grout from the rotary vertical shafts.
CONSTITUTION: The tubular casing K is rotated by a central gear D fixed to a shaft part C which is rotated or shaken by a driving device 5, while the upper end parts of the rotary vertical shafts 1 in plural are supported axially and rotatably at the lower surface part of a driving head 6 rotated or shaken by the shaft part C. While the hollow rotary vertical shafts in plural are rotated respectively within the rotating casing K, the whole of the group of the rotary vertical shafts 1 in plural is rotated or shaken for excavation. Furthermore, from jetting ports G located at the lower ends of the rotary vertical shafts 1 grout is jetted into the excavated soil and thereby the cement soil column is formed in the ground.
