1. Tensionless filling pile structure, comprise the solid or hollow cylinder that mainly forms by concrete, it is characterized in that, comprise:

  • steel concrete cylinder A (1), plain concrete cylinder B (2), finish rolling reinforcing bar (4), base ring (5), zinc-plated ripple steel cylinder urceolus (7), zinc-plated ripple steel cylinder inner core (8), stirrup (9) and sleeve pipe (10);

    Described steel concrete cylinder A (1) is provided with the cylindrical-shaped structure of a hollow space for the center, and the columned external surface coaxial rings of this steel concrete cylinder A (1) is covered with plain concrete cylinder B (2), filling backfill (3) in the described hollow space;

    Described zinc-plated ripple steel cylinder urceolus (7) is coaxial to be buried underground and is positioned between this steel concrete cylinder A (1) and the plain concrete cylinder B (2) and closely contacts with it respectively;

    Coaxial the burying of described zinc-plated ripple steel cylinder inner core (8) is arranged in this steel concrete cylinder A (1);

    Described base ring (5) is buried underground for metal material and is placed in this steel concrete cylinder A (1), and this base ring (5) is a circular ring structure, and through hole is set on it, and described through hole becomes circle-shaped and evenly is arranged on this base ring (5);

    Described finish rolling reinforcing bar (4) is in the circle-shaped equally distributed insertion described steel concrete cylinder A (1) vertically and is positioned between described zinc-plated ripple steel cylinder urceolus (7) and the zinc-plated ripple steel cylinder inner core (8);

    Described finish rolling reinforcing bar (4) one ends vertically stretch out this steel concrete cylinder A (1) one side end face, in the through hole of the described base ring of insertion (5) that the other end is paired and by nut and fastening the connecting as one of base ring (5);

    This finish rolling reinforcing bar (4) contacts the outer sleeve pipe (10) that is arranged with of part with concrete;

    The described excircle that is the circulus of circle-shaped equally distributed finish rolling reinforcing bar (4) formation evenly binds round the stirrup (9) of reining at least one metal material.
