Abstract
PURPOSE: To sufficiently attain the improvement of soft ground of either deep or shallow layer by simply regulating the operation of an expansible stirring shaft provided to a pile driver, etc., by expansibly connecting the stirring shaft with an outer pipe and inner pipe.
CONSTITUTION: While turning an telescoping stirring shaft 1 coupled with a vertically movable driver 3 toward the soft ground in a shrunk state, as shown by (a), the ground is excavated by a stirring blade 6 at its lower end down to a given position, as shown by (b), while injecting a soil stabilizer and mixing them. Then, after extending the telescoping stirring shaft 1, as shown by (c), the ground is again excavated by the stirring blade 6 to construct a stabilized layer, as shown by (d). After the completion of excavation, injection, and stirring, the telescoping stirring shaft 1 is lifted up to the position of (e) while turning, shrunk, and then pulled up again to complete the first process, as shown by (g).
