INSPECTION TOOL FOR CIRCULAR WATER CHANNEL STRUCTURE AND INSPECTION METHOD
To improve work efficiency for regeneration work by enabling the confirmation of a cross sectional area of a circular main water channel by a simple structure.SOLUTION: In a circular water channel structure 2 having a circular main water channel 21 and a slit 23 leading from an upper part of the circular main water channel 21 to an outer face, and laid underground extending along the side part of a road, an inspection tool 10 is provided for the circular water channel structure 2 for inspecting a cross-sectional shape of the circular main water channel 21. The inspection tool comprises an annular member 12 having an outer diameter smaller than an inner diameter of the circular main water channel 21 and a rod-like shaft part 11 extended radially outwards from an outer peripheral surface of the annular member 12. The width dimension along the center axis direction of the annular member 12 is formed smaller than the opening width of the slit 23.SELECTED DRAWING: Figure 6
【課題】簡単な構造により円形主水路の断面積を確認することが可能となり、更生作業にかかる作業効率の向上を図ることができる。【解決手段】円形主水路２１と、円形主水路２１の上部から外面に達するスリット２３とを有し、道路の側部に沿って延びるようにして地中に敷設された円形水路構造物２において、円形主水路２１の断面形状を検査するための円形水路構造物２の検査治具１０であって、円形主水路２１の内径より小さい外径をなす環状部材１２と、環状部材１２の外周面から径方向の外側に向けて延ばされた棒状の軸部１１と、を備え、環状部材１２の中心軸方向に沿う幅寸法は、スリット２３の開口幅より小さく形成された構成の検査治具を提供する。【選択図】図６
