Abstract: The double-channel drill rods of horizontal directional drilling system are taken as the research objects. According to the working principal of directional drilling, the structure and designing process of the double-channel drill rods are analyzed in detail. Besides that, intensity and sealing structure of the double-channel drill are calculated. The reliability of signal transmission of the double-channel drill rods is versified by some related technological experiments.

Key words: Horizontal directed-drilling, Double-channel drill rods, Signal transmission, Structural design
