Zusammenfassung: | To provide a cover concrete thickness inspection method enabling the cover concrete thickness of a reinforced concrete structure to be accurately and easily measured without installing a large scale scaffold.SOLUTION: There is provided is the cover concrete thickness inspection method that uses a small unmanned aerial vehicle to inspect the cover concrete thickness of a reinforcing bar in a reinforced concrete structure. The cover concrete thickness inspection method comprises: a first measurement step (step S1) of performing first measurement with the cover concrete thickness measurement sensor by moving the small unmanned aerial vehicle along the surface of the reinforced concrete structure; an analysis step (step S2) of performing frequency analysis on the measurement result of the first measurement step thereby obtaining a spectrum shape; a survey line evaluation step (step S3) of evaluating the status of the survey line where the first measurement has been performed from the spectrum shape; and a trajectory determining step (step S5) of determining the next movement locus from the evaluation result in the survey line evaluation step.SELECTED DRAWING: Figure 10
【課題】大掛かりな足場の設置などを行わなくても、鉄筋コンクリート構造物のかぶり厚を正確かつ容易に測定することが可能なかぶり厚検査方法を提供する。【解決手段】小型無人航空機を使用して鉄筋コンクリート構造物中の鉄筋のかぶり厚を検査するかぶり厚検査方法である。そして、小型無人航空機を鉄筋コンクリート構造物の表面に沿って移動させることでかぶり厚測定センサによる第1の測定を行う第1測定工程(ステップS1)と、第1測定工程の測定結果を周波数解析してスペクトル形状を求める解析工程(ステップS2)と、スペクトル形状から第1の測定が行われた測線の状況を評価する測線評価工程(ステップS3)と、測線評価工程における評価結果から次の移動軌跡を決定する軌跡決定工程(ステップS5)とを備えている。【選択図】図10 |
