PURPOSE: A pipe roof structure and a construction method thereof are provided to reduce construction time and costs by facing adjacent pipes with each other and connecting the facing pipes. CONSTITUTION: A construction method of a pipe roof structure is as follows. The ground is excavated using a pipe propelling device having an excavation bit(210), and a previously propelled steel pipe is pressed and propelled. The ground adjacent to one side of the previously propelled steel pipe is excavated, and a lateral propelled steel pipe(120) is pressed and propelled. A replacement steel pipe(130) is coupled to one side of the lateral propelled steel pipe and is pressed and propelled when the lateral propelled steel pipe is pressed and propelled. The replacement steel pipe pushes out the previously propelled steel pipe and is located at the position of the previously propelled steel pipe. |
