Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a water leakage repair device and a water leakage repair method capable of surely cutting off water leakage to the ocean from an existing concrete structure, by improving quality of an impervious layer formed on an undersurface of the concrete structure.SOLUTION: A water leakage repair device 1 of applying the present invention is to cut off water leakage of an existing concrete structure 5, and comprises a spray device 2 for spraying an impervious material 70 on an undersurface 5a of the concrete structure 5 from a cavity part 6 formed under the concrete structure 5 and a filling device for filling a foaming material in the cavity part 6. The spray device 2 is provided with an impervious material supply pipe 20 for supplying the impervious materIal 70 to the cavity part 6 by extending to the cavity part 6 from above the cavity part 6. The filling device is provided with a foaming material supply pipe for supplying the foaming material to the cavity part 6 by extending to the cavity part 6 from above the cavity part 6, and is used after using the spray device 2.SELECTED DRAWING: Figure 4
【課題】コンクリート構造物の下面に形成される遮水層の品質を向上させて、既設のコンクリート構造物から海洋への漏水を確実に遮断することのできる漏水補修装置及び漏水補修工法を提供する。【解決手段】本発明を適用した漏水補修装置1は、既設のコンクリート構造物5の漏水を遮断するためのものであり、コンクリート構造物5の下方に形成された空隙部6から、コンクリート構造物5の下面5aに遮水材70を吹き付けるための吹付装置2と、空隙部6に発泡材を充填するための充填装置とを備える。吹付装置2は、空隙部6の上方から空隙部6に延びて遮水材70を空隙部6に供給するための遮水材供給管20が設けられる。充填装置は、空隙部6の上方から空隙部6に延びて発泡材を空隙部6に供給するための発泡材供給管が設けられて、吹付装置2の使用後に用いられる。【選択図】図4 |
