The invention discloses a guiding and declination rectification device specially for underground pipeline transmission, and the problem of single guiding of transmission pipelines by a conventional guiding head is solved. The device is formed by the connection of couplings and a guiding cone, inclined end surfaces of the guiding cone are symmetrically and uniformly distributed with 4-8 guiding grooves, and declination rectification sheets are arranged in the guiding grooves. According to the guiding and declination rectification device, effects of dynamic suspension and mechanical dual support are formed in a transmission movement process of pipes, the principle is as follows: a guiding device is connected with the bottom end of the transmission pipeline, a guiding tapered body structure firstly satisfies the guiding effect of the single guiding head, the guiding grooves and the declination rectification sheets push well liquid or water in a pipe string transmission process, the well liquid shifts the declination rectification sheets so that a suspension centripetal force of the well liquid is applied to the guiding device, a central constraining force is applied to the declination rectification guiding device, the effects of declination rectification and guiding are really achieved, down-hole devices, apparatuses, and explosion apparatuses can be effectively protected, and the work efficiency of pipeline transmission work is improved.
