Abstract

PURPOSE: To equally stir and mix a ground improving agent in the ground by a method wherein when the soft ground is stirred, mixed and strengthened with a ground improving agent, and a processing machine is penetrated and pulled out of the ground, a ground improving agent can be exhausted into the ground. CONSTITUTION: In a system which excavates the ground, pours a milk cement and stirs the ground, two or more transmission shafts 3 are held by a driven pipe pile 1 and connect a hollow stirring shaft 5 having an excavating and stirring wing 4A and a stirring wing 4 B by means of a coupling 6. And further, a hollow ground improving agent pouring pipe 9 is held by the driven pipe pile 1 so as to slide vertically along the pile 1 and a valve case 13 of the pouring pipe 9 and a hollow stirring shaft 5 is connected through a connecting pipe 17. The stirring shaft 5 is rotated by the power of a driving part 7 and while the ground is excavated with the excavating and stirring wing 4A, or the stirring shaft 5 is being pulled out, a ground improving agent such as a cement milk etc., is exhausted from an exhaust port 15 at the point of the pouring pipe 9 and a ground improving agent exhaust port 12 which moves into a hollow stirring shaft through the connection pipe 17, thus, stirring and mixing equally the agent and the ground with the stirring wings 4B and 4A.
