WATER LEAKAGE INSPECTION METHOD
To provide a water leakage inspection method enabling accurate identification of a water leakage point in a pipe conduit buried in the ground without being affected by underground environment around the pipe conduit.SOLUTION: A water leakage inspection method according to the present invention includes: first image data acquisition step S100 of moving an antenna device on a probing path along a pipe conduit to acquire first image data in a time-series manner, and storing the first image data in a storage unit; pressurization step S200 of increasing pressure inside the pipe conduit; second image data acquisition step S300 of, after performing the pressurization step S200, moving the antenna device on the probing path to acquire second image data in a time-series manner, and storing the second image data in the storage unit; and water leakage location identification step S400 of comparing the first image data with the second image data stored in the storage unit along the time series to identify a water leakage location in the pipe conduit.SELECTED DRAWING: Figure 8
【課題】管路廻りの地中の環境に左右されず、地中に埋設された管路の漏水箇所を精度良く特定することが可能な漏水検査方法の提供。【解決手段】本発明に係る漏水検査方法は、アンテナ装置を管路に沿った探査経路上で移動させて第１の画像データを時系列的に取得すると共に、当該第１の画像データを記憶部に記憶させる第１画像データ取得工程Ｓ１００と、管路内の圧力を上昇させる加圧工程Ｓ２００と、加圧工程Ｓ２００を行った後、アンテナ装置を探査経路上で移動させて第２の画像データを時系列的に取得すると共に、当該第２の画像データを記憶部に記憶させる第２画像データ取得工程Ｓ３００と、記憶部に記憶される第１の画像データと第２の画像データとを時系列に沿って比較して管路の漏水位置を特定する漏水位置特定工程Ｓ４００とを含んでいる。【選択図】図８
