<p>PURPOSE:To enable work to be easily executed within a short time, by determining the kinds of conduits to be used and the number of the conduits previously based on the length and displacement of a piping section, to be changed. CONSTITUTION:At a point A, conduits 1-12 are arranged on six lines and two layers, and at a point B, the arrangement of the conduits is changed so that the conduits may be arranged on the one layer of six lines and on three lines and two layers. Based on the length and displacement of the section to be changed in arrangement, the kinds of conduits to be used and the number of the conduits for composing the conduit lines of the section to be modified in arrangement are previously contrived. Based on this contriving, the combined body of the used conduits is manufactured within a carried limit, and is connected and fixed in the section.</p> |
