Claims

[Scope of Claim for Utility Model Registration] In a sheath pipe device that protects a buried pipe from the earth pressure of the ground by surrounding the periphery of a buried pipe positioned relative to the ground, the sheath pipe device extends in the axial direction of the pipe. has a first sheath tube and a second sheath tube whose tube ends are adjacent to each other; the first sheath tube and the second sheath tube are independent from each other and are formed separately in the circumferential direction so that they can be assembled; One of the first sheath tube and the second sheath tube is a guide surface that slides and guides the other sheath tube in the perpendicular direction to allow relative displacement of the two sheath tubes in the direction perpendicular to the axial direction in the assembled state. A sheath pipe device for protecting a buried pipe, characterized in that the both sheath pipes are connected by a flexible cover member capable of absorbing the relative displacement.
