Zusammenfassung:PURPOSE:To completely stop the water leakage of a joint by inserting a water stopping member in which water-swelling rubber is installed in a long-size frame body having an H-shaped section into the joint. CONSTITUTION:A water stopping member 1 in which nearly round bar formed water-swelling rubbers 3 are installed in a frame body 2 having nearly an H- shaped section is inserted into the joint 5 of segments 4. Then, by driving in a fixture 6 for fixing the water stopping member 1, a caulking agent 8 such as high-early strength cement or epoxy resin is filled therein after the surface of the joint is dried. Further, a back-filling material 7 such as polymer cement or asphalt emulsion group mortar is also injected into the joint 5. Thereby, the leakage of water can be surely prevented.
