PROBLEM TO BE SOLVED: To prevent overflow of an increased volume of mixed soil, without recovering and carrying out the mixed soil, and enhance workability of construction work.SOLUTION: Overflow of mixed soil 50 is prevented in the following steps for: excavating continuously a widening groove 21 on a ground surface side, prior to excavating a trench 22; forming the mixed soil 50 of low flowability while excavating the trench 22 at a bottom of the widening groove 21 using an excavation kneader 30, by agitating and mixing a solidification material of low flowability discharged in the trench 22 with excavation sediment; erecting a stress material 60 in the uncured mixed soil 50; and having a portion of a volume of the mixed soil 50 increased by the solidification material and the stress material put in the trench 22 housed in the widening groove 21.SELECTED DRAWING: Figure 1 |
