PROBLEM TO BE SOLVED: To provide a protective structure for a deformed part of an internal pressure buried pipe superior in workability, economical efficiency, earthquake protection and the like, capable of resisting the thrust force to move the pipe by water pressure, by being applied to the deformed part such as a bent part of an internal pressure pipe conduit. SOLUTION: In this protective structure of the deformed part of the internal pressure buried pipe, the deformed part and a soil material are surrounded by a network or sheet-like sheet reinforcement material connected near the deformed part of the internal pressure buried pipe, or the deformed part and the soil material are wrapped by the sheet reinforcement material to integrate the deformed part and the soil material.
