Abstract

PURPOSE: To improve the large-diameter part of the ground by the stirring blade of an outer tube and the inside by the stirring blade of an inner tube by providing the stirring blades, discharge ports, and stirring and jet nozzles to the side of the outer tube and the exposure of the inner tube of a double tube in which the inner tube is projected from the tip of the outer tube.
CONSTITUTION: A double tube 1 consisting of an outer tube 2 and an inner tube is penetrated into the ground, and a hardening agent is sent under high pressure to the inner and outer tubes through swivel devices 13 and 14 while turning the double tube 1 by the motor 17 of a driver 18. On the other hand, a hardening agent in the inner tube is injected from the tip of a stirring blade 9 attached to the inner tube projected through a rotary bearing from the outer tube 2 and also the hardening agent is injected from a nozzle 12 provided to the side wall of the outer tube 2, during which period forced agitation is made by a stirring blade 11 attached to the side wall of the outer tube. Thus, the large diameter and inside parts of the ground can be completely improved by the stirring blades projectionally provided to the inner and outer tubes.
