Embodiment Construction
[0025] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.
[0026] see figure 1 , the outer diameter of the dual power auger drill pipe φ 1 50mm, rod inner diameter φ 2 It is 34mm, and the length L is 1000mm. It is composed of a male joint 1, a rod body 3, a female joint 2 and a helical blade 4 connected in sequence, and is welded into one body by friction welding. The male joint 1 is connected to the next drill pipe female joint 2 The connection end of the drill pipe joint 1 is composed of the straight shaft section 1-2 and the external taper thread 1-1 in turn; Threaded 2-1 connection composition. The thread type of the external tapered thread 1-1 of the male joint and the internal tapered thread 2-1 of the female joint is a positive spiral tapered thread, the taper is 1:8, and the pitch is 5.08mm (5 teeth per inch). The straight shaft section 1-2 of the male joint is pro...
