When the pile (P) according to the present invention consists of a continuous long bar of the same cross-section, a plurality of protrusions (hereinafter referred to as 'outer protrusion') on the outer circumferential surface of the pile (P) having a cross section, such as circular or square Is formed to protrude, each outer protrusion 101 is formed long while maintaining parallel to the longitudinal direction of the pile (P) in a state in close proximity to each other.

Each of the outer protrusions 101 is provided with a neck portion 102 extending from the outer surface of the pile (P), and forms a locking step 103 as an end portion of which the width is extended outward from the neck portion 102. .

Accordingly, each of the outer protrusions 101 forms a long rail groove 104 between each other, and the rail grooves 104 form a symmetrical shape substantially similar to the cross section of the outer protrusion 101, and the outer protrusions ( Due to the locking step 103 as the extended end of the 101, the inlet of each rail groove 104 is formed narrower than the inside of the groove.

In addition, the inner surface of the locking jaw 103, that is, the connection surface with the neck portion 102 becomes an inclined surface, and the locking jaw 103 is narrowed to the outside. The outer surface can also be configured as an inclined surface.

On the other hand, one or two or more protrusions (hereinafter referred to as 'inner protrusions') are also formed on the inner circumferential surface of the pile P, and the neck portion 112 extending from the inner circumferential surface of the pile is provided, and the neck portion is provided. Each of the inner protrusions 111 has the same shape as that of the outer protrusions 101, and the like, as the engaging jaw 113 is formed as an end portion of which the width is extended outward from the 112. It is formed in close proximity and does not form a rail groove between them.

Instead, at least two inner protrusions 111 may be formed to have one or more pairs facing each other.

Therefore, when a plurality of inner protrusions 111 are formed, it can be seen that each of the inner protrusions 111 in the same space is formed to face one center point.

Looking at this pattern, the outer surface of the pile (P) is at least two outer projections 101 that can form at least one rail groove 104 is formed in close proximity to the basic unit, whereas, One or more inner protrusions 111 may be formed on the inner surface.
