Abstract

PURPOSE:To make it possible to improve the ground with lesser columns by placing a sheet material between the improving columns and preventing the coming loose of earth when the improving columns for electing the ground improvement are provided in the ground. CONSTITUTION:The stirring shafts 1 having the stirring wings 2 to the lower end parts are thrust into the objective ground 4. And, the ground improvement material is supplied to the ground 4, and the improving columns 8 are formed by stirring after mixing poor soil into the ground 4 therewith. A sheet material 5 is placed between the stirring shafts 1, which is thrust into the objective ground 4 together with the stirring shafts 1 at a vertical posture. After that, the sheet material 5 is placed between the improving columns 8. Accordingly, the sheet material 5 shares the horizontal load between the improving columns 8, and at the same time, the loosening and falling out of earth from between the improving columns 8 is prevented; therefore, the required number of improving columns can be reduced.
