The invention relates to the field of spiral piles, in particular to a ductile cast iron spiral pile. The ductile cast iron spiral pile comprises a guide pipe, a rotor wing and a rotor wing sleeve, the guide pipe is made of ductile cast iron, the rotor wing is spirally shaped, the rotor wing and the rotor wing sleeve are fixedly connected, and the rotor wing sleeve and the guide pipe are connectedin a sleeving mode and are fixedly connected through a threaded connecting piece. Compared with the prior art, the ductile cast iron spiral pile has the beneficial effects that the rotor wing is fixedly installed on the guide pipe through the threaded connecting piece, so that separate carrying and rapid field assembly of the rotor wing and the guide pipe are achieved, the space of a transportation is fully used, the transportation cost is reduced, the efficiency of transportation is improved, the high corrosion resistance of ductile cast iron is fully used, and the cracking problem of the ductile cast iron due to welding is avoided.
本发明涉及螺旋桩领域，具体是一种球墨铸铁螺旋桩，包括导向管、旋翼和旋翼套管，所述导向管为球墨铸铁材质，所述旋翼呈螺旋状，所述旋翼与旋翼套管固定连接，所述旋翼套管与导向管套接并通过螺纹连接件固定连接。相对于现有技术，本发明球墨铸铁螺旋桩的有益效果为：旋翼通过螺纹连接件固定安装在导向管上，从而实现旋翼与导向管的分开装运以及快速现场装配，能够充分利用运输工具的空间，降低运输费用，提高运输效率，并且，能够充分利用球墨铸铁较高的耐腐蚀能力，避免球墨铸铁因焊接导致的开裂问题。
