MAINTENANCE METHOD OF NET-LIKE STRUCTURE AND MAINTENANCE DEVICE OF NET-LIKE STRUCTURE
To provide a maintenance method of a net-like structure and a maintenance device of a net-like structure that can estimate a deterioration state of a net-like structure and select repair measures according to the deterioration state.SOLUTION: A maintenance method of a net-like structure of the present invention includes the steps of: imaging an image of a net-like structure in the circumferential direction in association with the position in the length direction of the net-like structure; detecting a first abnormal part generated on the surface of the net-like structure based on the imaged image; acquiring a measured value of the net-like structure based on a non-destructive inspection in association with the position in the length direction of the net-like structure; detecting a second abnormal part generated in the net-like structure based on the measured value of the non-destructive inspection; and estimating a deterioration state of the net-like structure based on the positional relationship between a first position where the first abnormal part occurred and a second position where the second abnormal part occurred.SELECTED DRAWING: Figure 2
【課題】綱状構造体の劣化状態を推定すると共に、劣化状態に応じた補修対策を選択することができる綱状構造体の維持管理方法及び綱状構造体の維持管理装置を提供すること。【解決手段】本発明は、綱状構造体の維持管理方法であって、綱状構造体の長さ方向の位置に対応付けて綱状構造体の周方向の画像を撮像する工程と、撮像された画像に基づいて綱状構造体の表面に生じた第１異常部分を検出する工程と、非破壊検査に基づく綱状構造体の測定値を綱状構造体の長さ方向の位置に対応付けて取得する工程と、非破壊検査の測定値に基づいて綱状構造体に生じた第２異常部分を検出する工程と、第１異常部分が生じた第１位置と第２異常部分が生じた第２位置との位置関係に基づいて綱状構造体の劣化状態を推定する工程と、を備える綱状構造体の維持管理方法である。【選択図】図２
