PURPOSE:To promote mixture of soil with a hardener by providing soil with fluidity, by a method wherein a vibrating body, which is normally brought into a vibrating state, and a ground compacting machine having a discharge pipe are sunk in a soft ground as the air and the hardener are discharged through the discharge pipe. CONSTITUTION:A vibration type ground compacting machine 1, which is constituted such that a vibrating body 10 and a discharge pipe 2 are installed to a heavy frame 11, is suspended by means of a crane vehicle 4, and the vibrating body 10 is normally brought into a vibrating state. The compacting machine 1 is sunk down to a given depth in a soft ground as the hardener and the air are discharged through the discharge pipe 2, and discharge of the air is then stopped to gradually lift up the compacting machine. This provides soil with fluidity by adding the air during sinking of the compacting machine 1, and promotes mixture of the soil and the hardener, and causes the air to be exhausted to a ground surface and compacting of a ground during lifting up of the machine. |
