Anchor pile and installation method for same

An anchor pile comprising:

• a hollow pipe in which at least two insertion hole portions are formed on a predetermined location in a side surface of the hollow pipe;
• a resistance member which includes at least two protrusion portions and which is stored in the pipe and constructed to move along the pipe by application of a predetermined external force with an auxiliary tool that can perform a push-pull operation on the resistance member;
• and
• at least two guide portions which guide the protrusion portions of the resistance member such that the protrusion portions are protruded from the insertion hole portions to an outside of the pipe by the push-pull operation of the auxiliary tool on the resistance member,
• wherein the guide portions are regions of an outer circumference of the pipe wherein the guide portions are inwardly pressed slits in the side surface of the pipe such that the insertion hole portions are formed,
• wherein tip end portions of the guide portions and an edge end portion formed on both sides of the insertion hole portions and located in the outer circumference of the pipe wherein the tip end portions and the edge end portions are located substantially on a same straight line when seen in a direction substantially perpendicular to an axial direction of the pipe,
• wherein within the pipe, in a position in which the resistance member is stored, a stopper portion is provided to prevent further movement of the resistance member, and
• wherein the stopper portion comprises an inwardly projecting recessed portion of the side surface of the pipe.
