In the cement milk pile construction method, it is important to ensure the stiffness of a consolidation of pile end. We propose to attach a holed disk plate to the pile end in order to improve the end bearing capacity of a small sized steel pipe pile. We examine the characteristics of the end bearing capacity and the effectiveness of the end disk plate by laboratory experiments. The dimensions of the plate to apply to the cement milk method are discussed. Subsequently, actual size load tests are performed to confirm the validity of the improved pile end.
