Abstract
The purpose o this study, i.e air brbbles slurry is for the diaphragm wall construction. It is aimed to investigate the stabikizing mechanism of trench using air bubbles slurry and establish the quality control method. The air bubbles shurry, i.e air bubbles are mixed with the excavated soil,has cut-off avikity of water is lower than that of ventonite shurry.The control flow chart that it can be used for the diavilization using air bubbles shurry are reported. Now,it is bentonite shurry or bentonite CMC slurry which is used for the diaphragmwall construction.But it is cause,which makes construction cost high and excaveted soil vecomes industrial waste.Then the purpose of this study is to use air brbbles shurry collapse experiment and strenuous exertions experiment are reported. Relation between air brbbles slurry pressyre and water pressure.
