Abstract

PURPOSE: To stir and mix excavated earth and sand efficiently by rotating a plurality of rotary vertical shafts inside a casing while rotating or shaking the group of the rotary vertical shafts integrally and by jetting grout from the rotary vertical shafts.
CONSTITUTION: The upper end parts of a plurality of rotary vertical shafts 1 are supported axially and rotatably at the lower surface part of a driving head 6 which is rotated or shaken by a driving device 5 consisting of power and reduction units. The whole of the hollow rotary vertical shafts in plural is inserted into the tubular casing K and the excavation of the ground is conducted by rotating or shaking the rotary vertical shafts 1 in plural respectively. Then, a liquid substance is jetted from the jetting ports G of the hollow rotary vertical shafts 1 and the stirrng and mixing of the substance with excavated earth and sand are conducted efficiently, whereby a large-diameter soil cement column or the like is formed in the ground.
