Abstract

PURPOSE: To prevent the exudation and diffusion of a powder mixed into the ground by a method in which a powdery material mixed with an extender is injected into the excavated stirred layer of peaty ground by means of a gas feeding system and the gas alone is directed upwards and released to the open air.
CONSTITUTION: Stirring and injecting pipes 3 of a square cross section for an improving machine 2 for a given peaty ground 1 are added by connecting them, and an injecting balde 7 serving as an excavator is turned to form a pit 8 together with a stirred layer 9. After the excavating and stirring work to a given depth is complete, the injecting and stirring pipe 3 is pulled up, and at the same time a cement- sand mixture is supplied into an ejector 11 by opening the samper 23 of the ejector 11 with the aid of a gas feeding process in such a way as to supply the gas into the injecting and stirring pipe 3 through a swivel joint 6, and the cement-sand mixture is injected from the injecting and stirring blade 7. The gas goes up through an exhaust aperture 12, is decompressed in a decompression box 14, deprived of powdery dust, and then released through an exchaust duct 15 to the open air.
