PROBLEM TO BE SOLVED: To inexpensively repair a catch basin in a water flowing state in a short construction period. SOLUTION: A repair basin 100 is installed in the catch basin 1 in a state in which water flows through piping 2 and the catch basin 1; and a water sealing tube 105 is swollen in a state in which a piping opening 2a and an opening 102 of the repair basin 100 are aligned with each other. Thus, the water sealing tube 105 is pressure-bonded to the periphery of the opening 2a of the inside surface of the catch basin 1; the piping opening 2 and the opening 102 communicate with each other; and a space S, which is provided between the catch basin 1 and the repair basin 100 and on the periphery of the water sealing tube 105, is isolated from the inside of the piping 2 and that of the repair basin 100. The water is sucked up from the isolated space S in the catch basin 1; and subsequently, the space S is filled with grout 106 such as cement paste and mortar as shown in Fig.2(c).
