<p>PURPOSE:To prevent an excessive stress from being exerted on a support point of a flexible pipeline by making it possible to lay the flexible pipelines in a multiple layer manner. CONSTITUTION:Struts 12 are vertically disposed in an underground pit 10. In the struts 12, support arms 16 are fixed movably along the struts 12. Support frames 20 are fixed to the support arms 16, thus supporting at the surfaces thereof flexible pipelines 22 to be laid. Accordingly, since the support frame 20 supports the flexible pipeline 22 not at a point but at the surface, force to be exerted on the support portion of the flexible pipeline 22 is not concentrated, thereby preventing breakage. Moreover, the plurality of support arms 16 are fixed to the struts 12 so that the flexible pipelines 22 can be laid in a multiple layer manner.</p> |
