Abstract

PURPOSE:To obtain an underground buried pipe, in which a position or the like where an objective pipe is buried can be surely specified from above the ground, by mounting a radio responding tag to a surface of the buried pipe. CONSTITUTION:In an underground buried pipe A, a radio responding tag 2 is mounted to a surface of a pipe with a predetermined space in such a manner as called pipes 1b and 1d. In this tag, a non-volatile memory, in which an individual number and control information are written, is provided in a data memory part 4, and the radio responding tag 2 is probed by a read device 3 from above the ground B. In this way, an objective pipe buried position can be easily specified even without locating an objective pipe after digging work is executed.
