<p>PURPOSE:To execute work on site extremely easily and quickly by setting a branched seat having a screw section and a penetration hole previously, on a water distributing pipe. CONSTITUTION:When the work of a branched pipe is executed to be arranged, then a branched plug 11 is closed first, and the joints 22 of elbows or the like are screwed to the screw sections 20 of oscillating pipes 18, and the branched pipes 23 may be jointed to the joints 22. After that, when the cock 10 of the branched plug 11 is rotated, then fluid in a water distributing pipe main-body 5 is fed to the branched pipes 23 via the oscillating pipes 18. Accordingly, branched piping work can be extremely easily executed, and work in site can be simplified, and workability can be extremely improved. As a result, the arranging work of a water distributing pipe 3 and the pipe arranging work of the branched pipes 23 can be executed continuously and quickly. The oscillating pipes 18 are freely oscillated to the water distributing pipe main-body 5, and they are jointed to each other without fault even if there is any error in the dimension Of the joints 22 or the like, and even if ground settlement or the like is generated after the execution of work and the external force of earth pressure or the like is applied from an external section, the oscillating pipes 18 are oscillated to the water distributing pipe 3, and from jointed sections between auxiliary pipes 15 and the oscillating pipes 18, no fluid leaks, and they can be kept in a good jointed state.</p> |
