<p><P>PROBLEM TO BE SOLVED: To enable a drain pipe 20 to be easily arranged with a predetermined gradient; to make constructability superior; to reduce the number of supporting implements 16; and to reduce construction costs. <P>SOLUTION: In this drain piping structure 10, first-fifth supporting implements 16a-16e are arranged at intervals on a foundation 14, and the height of a lateral supporting portion 44 is adjusted to be lowered toward the fifth supporting implement 16e from the first supporting implement 16a. A long member 18 is inserted through a communication hole 52, fixed by means of respective communication portions 50 of the first and the fifth supporting implements 16a and 16e, and stretched in such a manner as to have a downgrade toward a junction pipe 28 from a drainage device 24. Additionally, a plurality of locking implements 22 are mounted on the drain pipe 20, and latched to the long member 18. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
