PHC COMPOSITE PILE WITH IMPLANT PILE FOR INCREASING DRIVEABILITY AND END BEARING CAPACITY

摘要

Provided is a PHC composite pile comprising: a pile which is inserted into a borehole; and multiple implant piles which are arranged on the end surface of the pile to be separated from each other and separately protrude. Therefore, the PHC composite pile secures improved pile driveability and end bearing capacity as the implant piles are directly inserted into the ground when piles for construction are driven; and prevents a decrease in driveability due to the resistance (buoyancy or the like) of cement milk as the cement milk injected into the borehole during a construction process is discharged from the end of the pile to the outside through the gaps (connection spaces) between the implant piles separated from each other.
