Abstract

PURPOSE: To perform the injection and stirring of powdered body into a pit without giving pollutions to the environments by a method in which a powder and a gas are injected into the pit excavated underground through a powder supply pipe in such a way that the powder and the gas are separated from eadh other while stirring the ground, the gas being separated is directed upwards from an aperture between the supply pipe and the pit, and the powder being separated is released on the ground surface.
CONSTITUTION: A pit is excavated undergound 2 to a given depth by excavating and stirring the ground by a jet blade 1 and a powder, e.g., cement, etc., together with a feed gas, is injectd into the ground 2 through a powder supply pipe 3. When lowering the pressure of the feed gas, the powder is separated from the feed gas by its own weight and mixed with the stirred ground to form a consolidated layer 4. The feed gas is discharged toward the ground surface through an aperture formed between the stirred ground and the supply pipe 3, while partial powder contained in the gas discharged is arrested in water tank.
