The invention discloses a self-spiral steel structure ground pile which comprises a pile pipe and spiral pieces wound on the periphery of the pile pipe and extending in the axial direction of the pile pipe, at least two spiral pieces are evenly distributed on the periphery of the pile pipe, and the ratio of the screw pitch P to the outer diameter R of each spiral piece ranges from 1.4 to 2.8. According to the ground pile, the ratio of the screw pitch P to the outer diameter R of a single spiral piece is optimized, the angle of the spiral piece is further optimized, self-rotation force can be formed when the ground pile is driven into the ground, construction of the ground pile can be achieved through a conventional excavator breaking hammer, operation is easy, and the construction cost is saved; only downward impact force is applied to the ground pile in the piling process, and the pile pipe is driven into the ground through self-rotation, so that the ground pile is prevented from being integrally bent due to counter-acting force of the ground in the piling process, a soil layer is more compact, the hardness of soil at a piling point can be improved, and the soil layer is ensured not to be loose; and the stability and the bearing capacity of the device in the long-time use process after being driven into the ground are ensured.
本申请公开了一种自螺旋钢结构地桩，包括桩管，以及缠绕于桩管外周并沿桩管轴向延伸的螺旋片，桩管外周上至少均匀布设有2个螺旋片，单个所述螺旋片的螺距P与外径R的比值为1.4‑2.8。该地桩通过优化单个螺旋片的螺距P与外径R的比，进一步优化螺旋片的角度，可以实现地桩在打入地下时形成自旋转力，通过常规的挖掘机破碎锤即可实现地桩的施工，操作简单，节约施工成本；该种地桩在打桩过程由于仅施加向下的冲击力，且桩管通过自旋转打入地下，避免在打桩过程中地桩整体受到地面的反作用力产生弯曲，并且使土层更加密实，可以提升打桩点土质的硬度，确保土层不松散，保证打入地下后在长时间使用过程中的稳定性和承载力。
