METHOD FOR REPAIRING HOLLOW CONCRETE STRUCTURE
To provide a repair method for a hollow concrete structure further easily and inexpensively.SOLUTION: A method for repairing a concrete structure in which a cylindrical form 10 is embedded in concrete comprises a first step of exposing the form 10 by removing the concrete around the form 10, a second step of inserting a longitudinal bag body 20 made of a flexible material into the form 10 through an opening part 13 of the form 10 in the cylindrical axial direction of the form 10, a third step of filling the inside of the bag body 20 with a fluid 23, and a fourth step of forming a new concrete layer 41 in the area where the concrete has been removed.SELECTED DRAWING: Figure 1
【課題】中空コンクリート構造体の補修を、より容易に且つより安価に行う。【解決手段】コンクリート内に筒状を成す型枠１０が埋設されたコンクリート構造体の補修方法において、型枠１０の周囲のコンクリートを除去して型枠１０を露出させる第１工程と、型枠１０の開口部１３を通じて型枠１０の内部に可撓性を有する素材からなる長手形状の袋体２０を型枠１０の筒軸方向に沿って差し入れる第２工程と、袋体２０の内部に流体２３を充填する第３工程と、コンクリートを除去した部分に新たなコンクリート層４１を形成する第４工程とを備えるコンクリート構造体の補修方法とした。【選択図】図１
