| Outline of Final Research Achievements |
In this study, a new mechanism to reduce the soil adhesion on the excavating bucket was proposed. In order to reduce the soil adhesion, the water seeps out from many holes of bucket surface through porous media because it was confirmed that the water film formed between soils and the surface of materials reduced the soil adhesion. It was found that the minimum water addition was 0.05g/cm2 for clay soil. Furthermore, it was confirmed through several experiments that the minimum water addition was 0.06g/cm2 regardless of the soils.
