The utility model discloses the helical tube bores structure includes drill bit, outer wall load steel pipe, inside lining steel pipe, bolt or nut, handle. The load steel pipe is thick steel pipe, the bottom tipped drill, and the outside welding handle in top, bore on the top has the cross bore in order to insert the bolt. The drill bit is hollow cone shape, and the cone peripheral hardware is threaded. Inside lining steel pipe top sets up bolt or nut in order to avoid released soil auger by the earth pillar. The inside lining steel pipe is divided into two so that separate the earth pillar along the diameter section. This helical tube bores utilizes the drill bit external screw thread screw in soil body, utilizes drill bit bottom cavity separation earth pillar, utilizes the inside lining steel pipe to separate earth pillar and outer wall load steel pipe, conveniently fetches earth and separates the save earth pillar, has combined the advantage of anger with barrel drill, more laborsaving realization the purpose that fetches earth of big degree of depth original state.
