Kind Code:

A

Abstract:

PROBLEM TO BE SOLVED: To provide a modifier mixing method into soft soil that offers a high degree of freedom of application, and can simply and inexpensively mix soft soil such as dredge soil and a modifier such as steel slag.SOLUTION: A throw-down conveyor 5 is installed such that an edge part on a throw-down side is higher by a desired drop height from a throw-down ground surface in front of a top of slope 2a, and a pair of downstream-side regulating side walls 8, 9 is installed on the throw-down ground surface, the side walls extending in a downstream direction from a throw-down point. Modifier-added soft soil is thrown down between the downstream-side regulating side walls 8, 9 from the throw-down conveyor, the modifier-added soft soil having modifier 4, 4, ... mixed at a prescribed ratio into soft soil 3. Modifier-added soft soil 17 is made to accumulate between the downstream-side regulating side walls 8, 9 while retaining a constant mixture effective thickness. Furthermore, the modifier-added soft soil 17 is thrown down sequentially from the throw-down conveyor 5 onto the modifier-added soft soil 17 accumulated between the downstream-side regulating side walls 8, 9, thus mixing the modifier 4, 4 with the soft soil 3.SELECTED DRAWING: Figure 1
