DRILLING METHOD OF CONCRETE STRUCTURE
To reinforce a structure in which an open hole is penetrated with efficiency and effectively and avoid a harmful effect by drilling to the structure.SOLUTION: In a drilling method of a concrete structure 1 for forming an open hole in the concrete structure by a cutter of a drill, a reinforcement step of adhering a reinforcement sheet 10 with reinforcement fiber to an exterior surface area 5 to be reinforced on an outer peripheral side of a drilling corresponding part 1A at an exterior surface 1a of the structure 1 is performed before performing a drilling work step by the drill.SELECTED DRAWING: Figure 7
【課題】貫通孔が貫通形成される構造体を能率良く、効果的に補強して、穿孔による構造体への悪影響を回避する。【解決手段】コンクリート製の構造体１に穿孔機のカッターで貫通孔を形成するコンクリート製構造体の穿孔方法であって、穿孔機による穿孔作業工程を実行する前に、構造体１の外面１ａにおける穿孔相当箇所１Ａの外周側の補強対象外面領域５に、強化繊維を備えた補強用シート１０を貼り付ける補強作業工程を実行する。【選択図】図７
