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
【課題】適用の自由度が高く、浚渫土等の軟弱土と製鋼スラグ等の改質材とを簡易且つ安価に混合することができる軟弱土に対する改質材混合方法の提供。【解決手段】投下側端部が法肩２ａ手前の投下先地面より所望の落下高さ分だけ高くなるように投下用コンベア５を設置するとともに、投下先地面に投下地点から流下方向下流側に延長された一対の流下規制側壁８，９を設置し、軟弱土３に所定の比率で改質材４，４...を添加した改質材添加軟弱土を投下用コンベアより流下規制側壁８，９間に投下し、流下規制側壁８，９間に改質材添加軟弱土１７を一定の混合有効厚を維持させつつ貯留させ、且つ、流下規制側壁８，９間に貯留された改質材添加軟弱土１７上に投下用コンベア５から改質材添加軟弱土１７を順次投下することにより、改質材４，４と軟弱土３とを混合させる。【選択図】図１
