<p>PROBLEM TO BE SOLVED: To provide a communication line placement structure which can be applied in a non-open-cut method, and in which permanently stable communication lines can be composed inside sewers. SOLUTION: In this communication line placement structure, the communication lines are composed in the sewers such as laterals extended to respective households, and sewers including main pipes 1 and branch inlets 2. A hook-and- loop fastener female surface 6 is attached to the sewer 1, and a hook-and-loop fastener male surface 8 is attached to a support 3. By engagement of the hook- and-loop fasteners 6 and 8, and adhesion of the hook-and-loop fasteners 6 and 8 to each other, the communication lines extended along pipe inner surface 7 are composed.</p> |
