The invention discloses a steel pipe special-shaped uplift pile. The steel pipe special-shaped uplift pile comprises a pile body, a pile cap arranged at the upper end of the pile body, a pile tip arranged at the lower end of the pile body and a spiral rib plate which is arranged on the outer circular surface of the pile body and extends to the pile tip from the pile cap, wherein the spiral rib plate is of a spiral structure, and the pile body is a circular steel pipe. The steel pipe special-shaped uplift pile is light in dead weight, and additional stress borne by soil below the bottom of thepile can be reduced, so that settlement deformation of the soil is reduced, and normal use of a building (structure) is guaranteed; and under the same condition, the pile side resistance can be increased after the spiral rib plate is arranged on the smooth pile wall, so that the bearing capacity of the pile is improved. The invention provides a construction method of the steel pipe special-shapeduplift pile.
本发明公开了一种钢管异形抗拔桩，包括桩体、设置在桩体上端的桩帽、设置在桩体下端的桩尖和设置于所述桩体的外圆面上且为从所述桩帽处开始延伸至所述桩尖处的螺旋肋板，螺旋肋板为螺旋状结构，桩体为圆钢管。本发明的钢管异形抗拔桩，自重轻，可使桩底以下土体受到的附加应力降低，从而降低土体的沉降变形，保证建(构)筑物的正常使用；而且在同等条件下，通过在光滑的桩壁设置螺旋肋板后可增加桩侧阻力，从而提高桩的承载力。本发明提供了一种钢管异形抗拔桩的施工方法。
