PURPOSE: A steel pipe jacking method and device for maintaining the planar, longitudinal, and linear state of a steel pipe are provided to reduce construction costs by enabling curve construction without excavation. CONSTITUTION: A steel pipe jacking method for maintaining the planar, longitudinal, and linear state of a steel pipe is as follows. Multiple steel pipes(11,12,13,14) are manufactured in consideration of the linear state of an underground structure. One or more linear adjustment devices(20) are installed between the adjacent steel pipes which require linear adjustment. The jacking postures of the steel pipes are adjusted using the linear adjustment devices. A following steel pipe is inserted using a hydraulic jack(30) to jack the steel pipes in a designed linear direction. |
