The invention discloses a manufacturing method of a multi-pipe tubular joint, which comprises the following steps of: arranging a contour line which is consistent with the projection of the profile of a multi-pipe tubular joint to be manufactured on the bottom surface of an assembly jig as a manufacturing platform; arranging a mine pipe for the multi-pipe tubular joint on the assembly jig, enabling the outer side lines of the primary pipe to be matched with the profile contour line of the primary pipe in the contour line to locate the primary pipe, and then temporarily fixing the primary pipe on the assembly jig; sequentially locating secondary pipes in secondary pipe installation positions on the primary pipe, and then temporarily fixing the located secondary pipes on the primary pipe; detecting the positions of the temporarily fixed secondary pipes; in case of conforming to the design positions of the secondary pipes of the multi-pipe tubular joint, welding the secondary fixed pipes on the primary pipe; and
