Evaluation of Durability and Waterproofing Characteristic of Cast-in-Place Piles Using Surfactant Grout at the Field Tests
In case of underground construction affected by groundwater, CIP (cast-in-place pile) method is generally used to solve the geohydraulic problem. However, as this method has poor connectivity between piles, an auxiliary cut-off method is required in many cases. In this study, a newly-developed cut-off wall (H-CIP) without auxiliary method, by using surfactant grout (Hi-FA), which improves anti-washout performance and infiltration ability, is introduced and the field applicability of H-CIP method is evaluated. CIP and H-CIP piles were installed under the same ground conditions and field and laboratory tests were conducted to verify the performance, respectively. As a result, a newly-contrived H-CIP method shows higher field performance in terms of cut-off and strength than conventional CIP method.
