The present invention relates to a pile having multiple concavo-convex shapes on the lowermost end thereof and a pile construction method using the pile having multiple concavo-convex shapes on the lowermost end thereof, to a pile which is used as a foundation pile for a structure to be supported on the ground and a construction method which uses the pile and, more specifically, to a steel-piece integral steel pipe pile structure which has the cross sectional shape on the lowermost end thereof formed by integrating a capped hollow pile with a steel piece formed on the circumference thereof and a construction method using the steel-piece integral steel pipe pile structure. The pile construction method using the pile having multiple concavo-convex shapes on the lowermost end thereof according to the present invention is provided to minimize pile subsidence by properly maintaining a distance between the lower end of a cement-based filling part and the lower end of a support pile and to improve the end bearing capacity of the pile by enabling the cement-based filling part and the support pile to be integrally moved by preventing slip generation between the cement-based filling part and the support pile as well as by expanding the area of the part of the pile. |
