To provide a soil improving method capable of preventing the moisture content of improved sediment from being excessively lowered even if cement and quick lime are added to rather dry sediment, providing high quality improved sediment, and manufacturing soil concrete and improving contaminated soil in a soil improving field.
Sediment, an improver, and water or a soil improving solution are led from a hopper 10, a container 11, and a water adding device 40 installed in a self-running soil improving machine 1 into a mixing device 15, respectively, and mixed with each other. The improved sediment mixed with the improver falling from the mixing device 15 is conveyed to the outside of a vehicle body 9 by a conveyor 16. The soil cement is manufactured by using cement as the improver. By using the soil improving solution in place of water, the contaminated soil is improved.
