Abstract
A conventionally available pile for civil engineering work is constructed such that the pile has in its inside a core body with wedges that stick into soil deep in the ground and function to prevent the pile from coming out of place. A problem exists with such a pile in that placing the core body at an appropriate position inside the pile is difficult. A pile for civil engineering work of this invention enables a core body to be placed at an appropriate position and labor required for the placement to be reduced. A pile (1) for civil engineering work is characterized in that, for example, a guide rail (4) that enables a core body (6) to be guided is provided inside a body of the pile (1), the core body (6) is guided through the guide rail (4), and wedges (6a, 6b) are appropriately guided to cut/pushed-in openings (2a, 2b, 3a, 3b).
