To provide a propulsion method for a burying pipe made of a synthetic resin to facilitate burying of a burying pipe and burying of a protection sheet without excavating a ground by an excavator.
A temporary conduit is inserted as soil is excavated by a pre- excavation body to build a guidance passage. After the temporary conduit reaches a given position, a burying pipe is mounted on the pre-excavation body and by reversing the pre-excavation body, the burying pipe 7 is buried in the guidance passage 6. A temporary guidance pipe 5 is inserted as soil is excavated by a propulsion body 8 with a blade in a position situated above by a given distance from the burying pipe to build a guidance passage 9. After the temporary conduit reaches a given position, a protection sheet 10 is mounted on the propulsion body with a blade and by reversing the propulsion body with a blade, the protection sheet is buried in the guidance passage.
