To save labor and improve efficiency in estimation of a position where a buried pipe is buried.SOLUTION: A burying position estimation unit 42 estimates the position and depth of an underground buried structure based on a position measured by a survey position measuring device and an intensity pattern of a radio wave received by a radar survey device. A buried pipe determination unit 44 determines whether the underground buried structure continues linearly based on the position and depth of the underground buried structure estimated by the burying position estimation unit 42, and determines the underground buried structure determined to continue linearly as a buried pipe.SELECTED DRAWING: Figure 2 【課題】埋設管が埋設された位置の推定を省力化・効率化する。【解決手段】埋設位置推定部４２は、探査位置測定装置が測定した位置とレーダー探査装置が受信した電波の強度パターンとに基づいて、地中埋設物の位置及び深さを推定する。埋設管判定部４４は、埋設位置推定部４２が推定した前記地中埋設物の位置及び深さに基づいて、前記地中埋設物が線状に連続しているか否かを判定し、線状に連続していると判定した地中埋設物を、埋設管であると判定する。【選択図】図２
