<p>PROBLEM TO BE SOLVED: To provide a conduit structure which can lay a cable conduit while conducting connection work easily without requiring heavy machinery for laying the conduit, in a multiple conduit for laying cables which permits a cable to be laid additionally in a large conduit if necessary. SOLUTION: A conduit structure body 1 is constituted of a pair of resin troughs 1a, 1a combined so as to face each other. Respective resin troughs 1a are formed with a groove 10 with a semicircular cross-section continuously in a longitudinal direction so as to form a single circular hole in a condition combined so as to face each other, and at both the end parts in the groove 10, a groove-shaped recessed part 11 of bed width is formed continuously along a circumferential direction of the groove 10. By a joint member 2 which is formed with collar parts 20 guided to the recessed parts 11 of the respective conduit structures 1, 1 continuously or discontinuously in a circumferential direction at both the end parts, it is possible to connect the conduit structures 1, 1, and constitute a laying conduit.</p> |
