Abstract

A V-shaped pipe-jacking tunneling machine is characterized in that each of a reducer I, a reducer II, a reducer III, a reducer IV and a reducer V during operating drives a drill at the front end of the corresponding reducer through a drill rod at the front end of the corresponding reducer; four rotating shafts during rotating drive rotating arms to rotate through fixed arms respectively; the five drills during rotating cut soil mass in the front of the drills, the soil mass and water are mixed to form slurry, so that an approximately V-shaped hole combined by five round holes is formed, the rotating arms on the four rotating shafts cut edges of the approximately V-shaped hole combined by the five round holes into flat and straight edges during rotating, and the slurry is discharged out of a jacking pipe through a slurry pump. The V-shaped hole is formed during advancing of the pipe-jacking tunneling machine, and thereafter, a long-distance V-shaped pipe-jacking pipeline is formed by pipelines with V-shaped sections during advancing section by section.
