Abstract

The invention discloses a pile foundation for a high-voltage transmission line iron tower. The pile foundation comprises pile anchors, a soft soil foundation, outer metal corrugated pipes, inner metal corrugated pipes, tower bolts, nuts, embedded rings, bolts, anchor plates, anchor bolt centralizers and nuts. Due to the fact that pile anchors are connected in an overlapped manner, horizontal acting force resistance of the pipe foundation is increased effectively, drawing force resistance of the pile foundation is increased at the same time, and pile foundation collapse is prevented effectively. The pile foundation is low in construction difficulty, and capable of being constructed on the soft soil foundation and effectively bearing the loads of the grounding wires and a tower body.
