Evaluation of Field Applicability of Cast-in-Place Piles Using Surfactant Grout
In case of underground construction affected by groundwater, CIP (Cast-In-Place Pile) method is generally used to solve the geo-hydraulic problem. However, as this method has poor connectivity between piles, an auxiliary method for cut-off is required in many cases. In this study, a newly-developed cut-off wall (H-CIP) with no auxiliary method, by using surfactant grout (Hi-FA), which improves anti-washout and infiltration ability, is introduced, and the field applicability of H-CIP method is evaluated. CIP and H-CIP piles were installed with same ground conditions, and field and laboratory tests were conducted to verify the performance, respectively. As results, newly-contrived H-CIP method shows higher field performance for cut-off and strength than conventional CIP method.
