Title: Protective device for buried piping joint
Inventor: KIM JOO YONG
IPC: F16L55/00

Abstract: The present invention provides an apparatus for protecting a connection unit of a buried pipe, which includes: the connection unit connecting ends of a pair of buried pipes buried in the ground; a protection pipe disposed outside the connection unit and spaced apart from the buried pipes and the connection unit; and a support unit supporting the protection pipe such that the inside surface of the protection pipe and the outside surface of the connection unit are separated from each other. The buried pipes move at an inner space of the protection pipe by expansion and contraction due to temperature changes.
