The present invention relates to a foundation structure vertically installed on the ground, and comprising: an upper support layer 10 formed on the ground in the vertical direction; and a lower support layer 20 formed so as to extend downward from the upper support layer 10 and such that the width thereof is less than that of the upper support layer 10. The disclosed upper support layer 10 and the lower support layer 20 are structures formed from soil solidified by means of feeding and mixing an earth and soil-solidifying agent therein, and therefore are efficient and prevent overload due to boring equipment.

A foundation pile 1 is disclosed. The foundation pile 1 includes a central axis member 10 that extends vertically in the up-down direction; a base plate 11 formed on the upper end of the central axis member 10 to fix the upper structure 2 at the upper end; and a circumferential member 20 provided on the upper side circumference of the central axis member 10 to reinforce the upper side circumference of the central axis member 10, wherein the upper surface of the circumferential member 20 is formed so as to come into contact with the lower surface of the base plate 11 without any gap.

The present invention relates to an anchoring system (1) comprising an anchor pile (2) configured to be embedded in a borehole (30) drilled in a ground surface. The anchor pile (2) comprises an elongate main body (3) having a longitudinal axis (L) and comprising an upper end (4) and a lower end (5). The cross section of the elongate main body (3) increases along a portion of the longitudinal axis (L) in the direction from the upper end (4) to the lower end (5) defining at least one bearing surface (7a, 7b) such that in use an annular gap (32) for receiving locking media is defined between the at least one bearing surface (7a, 7b) and the adjacent portions of the borehole (30). The anchor pile (2) is locked in position within the borehole (30) on receipt of locking media within the annular gap (32) and abutment of the loose material with the bearing surface (7a, 7b).
