<p>PURPOSE:To reduce labor cost for plumbing, by a method wherein a plumbing unit for drainage, in which flexible pipes for branch drainage are connected with a flexible pipe line for main drainage through pipe joints, in carried in a construction site and is connected with domestic utensiles for the objects of the drainage. CONSTITUTION:A plumbing unit 1 for drainage prefabricated at a factory is formed by each cutting flexible pipes 3, 5 to 8, on the basis of designed measurements, by doing the treatment of the end parts thereof, and by connecting the flexible pipes with each other through T-shaped pipe joints 4. A stack and adapters 10 are respectively connected with the end parts of the flexible pipes 3a, 5 to 8. The pipes 5 to 8 for branch drainage are bent along the pipes 3 (3a to 3c) for main drainage and are made in compact shape, and thus without difficulty, the plumbing unit 1 can be transported from the factory and can be carried in a construction site. The plumbing unit 1 carried in the construction site is restored in actual constructional shape and is placed on supports on a slab. In this way, the pipe 3a for the main drainage is connected with the stack and the pipes 5 to 8 for the branch drainage are connected with domestic utensiles for the objects of the drainage.</p> |
