PURPOSE: To efficiently produce improved soil by a method in which excavated soil is ground while removing stone blocks, etc., by instantaneously grinding or crushing it and then screened through a sieve, and the soil is sent to a mixer and mixed with a cement-based additive in a continuous process.
CONSTITUTION: Excavated soil, before it assumes a viscous behavior, is ground or crushed instantaneously by a cutter loader, etc., for example, and screened through a sieve, and the soil is sent to a mixer and then mixed with cement or a mixture of cement and an additive in a continuous process. Thus, processes from the grinding of accumulated residual soil to screening, mixing, and the discharge of improved soil can be performed with a high efficiency in a continuous flow system.
