<p>PROBLEM TO BE SOLVED: To efficiently perform connection of cables and installing work of a protective tube without expanding a space of a work site. SOLUTION: This protective tube 1 is divided in the lengthwise direction, and is composed of protective tube main bodies 2a and 2b to form a cylinder body in a condition where cables 4a and 4b are contained by superposition and reducers 3a and 3b which are fitted to both end parts of the protective tube main bodies 2a and 2b formed in the cylinder body and into which the cables 4a and 4b are inserted. Reinforcing members 6a, 6b, 7a and 7b which position the protective tube main bodies 2a and 2b at superposing time and have the reinforcing action, are arranged in lateral directional end parts of these protective tube main bodies 2a and 2b. Long diameter injection holes 11 to inject a hardening agent are also formed in the lengthwise direction on either one side surface of the protective tube main bodies 2a and 2b.</p> |
