PROBLEM TO BE SOLVED: To provide a repair drain made of a soft thermoplastic resin, the molding method of the repair drain made of a soft thermoplastic resin, and a repair drain structure which can increase the reliability of watertightness during repair, which can secure a sufficient drainage volume, which can reduce the number of members and work processes, which can be provided at a low cost, and which can simplify the construction during re-repair. SOLUTION: The vertical repair drain made of the soft thermoplastic resin is formed by molding an extra-long drainage pipe which is 200 to 500 mm long and a flange-shaped member in one piece. The repair drain is molded in one piece by dipping molding, and the extra-long drainage pipe of the repair drain is inserted to the drain outlet of the existing drain. A vertical repair drain structure is provided by welding the flange-shaped member of the repair drain and the back of a newly-provided water-resistant sheet made of the thermoplastic resin together. Furthermore, the vertical repair drain structure is made a double-drain structure by the combination of a second repair drain. COPYRIGHT: (C)2010,JPO&INPIT |
