<p>PROBLEM TO BE SOLVED: To simplify the work of binding and burying conduits for holding cables, make the work easy even when some obstacle lies in the way for the burying, and give the conduit line good strength against the loads of vehicles bearing thereupon after the backfilling. SOLUTION: Inside a receiving frame body 1 formed of a strip of plate and having the shape of a box several conduits are laid in parallel and with a top frame plate 6 attached over them the conduits are bound together. The receiving frame body 1 has at its bottom a pair of feet 14, 14 so that the receiving frame body 1 can be placed in a burying position in a cut in the ground as prescribed. Between the two side walls 2, 2 of the receiving frame body one or more partition plates 17 are placed transversally so that the conduits can be laid in two or more layers. Furthermore, there are provided spacers 11 each of which has such a shape as to be fitted between conduits, having on the two sides of the upper part arc-shaped hollow surfaces that fit over the peripheries of the conduits.</p> |
