The construction method of a steel pipe is disclosed. The construction method of a steel pipe is capable of achieving an easier construction of a steel pipe and minimizing the construction period thereby in such a manner that neighboring steel pipes are roughly arranged at a construction site, and ends of the neighboring steel pipes are held using a shaper are externally pressurized in a radial direction for thereby achieving a perfect circle shape, and then the steel pipes are arranged in a straight line shape, and the ends of the steel pipes are arranged to abut with each other or are inserted each other, so that the conjunction portions of the inner or outer surface of the steel pipe are welded. |
