グメント。 comprising two first joint end surfaces that are parallel to each other and approximately along the circumferential direction of the excavation hole; and two second joint end surfaces that are parallel to each other and approximately along the axial direction of the excavation hole;
In a segment in which a spiral body is constructed on the inner surface of the excavated hole by sequentially connecting second joint end surfaces along the axial direction of the excavated hole, the first joint end surface and the second joint end surface are connected. In each of the two diagonal portions that are imaginary when extended, a third portion is formed obliquely at a predetermined angle with respect to the circumferential direction of the excavated hole, extends in the traveling direction of the helical body, and is parallel to each other.
A segment characterized by having a joint end surface formed therein.
