Underground cavity inspection system and underground cavity inspection method

摘要

An underground cavity inspection system (1) according to one aspect of the present invention is installed in a conduit buried underground, a detector (11) capable of detecting muons, a position adjustment section (12) capable of adjusting the position of the detector in a direction in which the pipe extends, and a detector (11) An analysis section (13) for identifying the position of the cavity in the underground is analyzed by analyzing the flux information of the muon detected in the above described manner.The present invention provides an underground cavity inspection system capable of easily inspecting cavities in underground.
