<p><P>PROBLEM TO BE SOLVED: To provide a piping method of drainage equipment capable of preventing the occurrence of a waste material at a construction site so that cutting work of a drain riser at the construction site can be omitted and, at the same time, increasing working efficiency to shorten a construction period of time. <P>SOLUTION: The piping method of the drainage equipment includes a process setting each length dimension and the total dimension of the first waste stack 101 and the second waste stack 102 connected in series based on a distance between drain joints, a process mass-producing the first waste stack 101 and the second waste stack 102 based on a setting dimension, a process connecting an insertion port in the lower end section of the second waste stack 102 to an upper socket of the drain joint installed on the downstairs through a sealing compound, a process connecting an insertion port in the upper end section of the second waste stack 102 to the second socket 62 of the first waste stack 101 before or after the second waste stack 102 is connected to the upper socket of the drain joint and a process connecting a lower straight pipe section of the drain joint of the upstairs to the first socket 13 of the first waste stack 101 through the sealing compound after the first waste stack 101 communicated with the upper socket of the drain joint in the downstairs through the second waste stack 102 has been positioned. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
