COVER THICKNESS MEASUREMENT METHOD, AND COVER THICKNESS MEASUREMENT SYSTEM
To provide a cover thickness measurement method and a cover thickness measurement system for measuring cover thickness while suppressing groundwater outflow.SOLUTION: A cover thickness measurement system 10 measures a cover thickness of an existing concrete pile having a pressure-resistant board attached around an upper periphery. A control section 21 of the cover thickness measurement system 10 acquires measured reflection properties around an exploration hole of transmitted waves emitted from a radar exploration device 15 inserted into the exploration hole formed to extend vertically in the existing pile. The control section 21 calculates an outer peripheral position and a position of a pile main reinforcement of the existing pile using the acquired measured reflection properties, and identifies the cover thickness of the existing pile using the calculated outer peripheral position and the position of the pile main reinforcement.SELECTED DRAWING: Figure 1
【課題】地下水の噴出を抑制しながら、かぶり厚さを計測するためのかぶり厚さ計測方法及びかぶり厚さ計測システムを提供する。【解決手段】かぶり厚さ計測システム１０は、耐圧盤が上部周囲に設けられたコンクリート製の既存杭のかぶり厚さを計測する。かぶり厚さ計測システム１０の制御部２１は、既存杭に鉛直方向に延在して形成された探査孔に挿入されたレーダ探査機１５から発信された送信波の探査孔の周囲の計測反射性状を取得する。制御部２１は、取得した計測反射性状を用いて、既存杭の外周位置と杭主筋の位置とを算出し、算出した外周位置と杭主筋の位置とを用いて、既存杭のかぶり厚さを特定する。【選択図】図１
