Abstract
Cast-in-place pile (CIP) has been temporarily or permanently used for the support of the braced cut system during the metro construction project. The function of CIP wall is the purpose of supporting the braced cut wall as well as water barrier system during the construction of underground structures. The construction of CIP wall has a problem of strength loss when it is being installed in the ground where the water table is near the ground level. In this study, a new concept of cast-in-place pile wall is presented to overcome the stress loss problem in the ground with the high water table due to the dilution of cement component and segregation of cement particles. The surfactant grout was developed and called high-performance and multi-functional agent (Hi-FA) for the use in the construction of cast-in-place pile in the high water ground condition. The first part of this paper describes about the material properties and characteristics of Hi-FA grouts as well as the results of laboratory tests for grouts material. The second part of the paper presents the evaluation on the field applicability of cast-in-place pile using surfactant grout (H-CIP) at the metro construction project.
