Release and lock in line (A). By repeating this operation in sequence, a plurality of fixing bands (5) are attached in the pipe line at appropriate intervals in the length direction, and when all the attachments are completed, the carriage (1) is removed from the pipe line (A). After that, the filamentous body (B) is sequentially inserted into the fixing portion (6) provided on the fixing band (5), and the filamentous body (B) is laid in the conduit (A). FIG. 3 shows a cross-sectional view of the conduit (A) in such a state, and the filament (B) is fixed near the wall surface of the conduit (A). Although FIG. 3 shows an example in which the fixing part (6) is provided on the top of the fixing band (5), the position of the fixing part (6) is not limited to the top and any position of the fixing band (5) is shown. Can be provided.
