FIELD: pipe laying; pipeline transport. ^ SUBSTANCE: invention is designed for laying underground pipelines in permafrost ground, swamps and water logged sections. Proposed device contains load-bearing belt for suspending onto pipeline whose end parts form containers made for filling with loose material at ballasting of pipeline and at least two upper flexible belts. Each said container is furnished with spacing frame on outer leg of which end of load-bearing belt and ends of flexible belts are secured, the latter being attached to load-bearing belt in its middle part. To increase ballasting capacity, each container is furnished with pair of end face partitions. Spacing frames are made detachable, longitudinal and cross members of each frame are fixed at assembling by wedging ends of cross members in slots made in legs of longitudinal members of frames by means of elastic deformation of said outer leg. ^ EFFECT: simplified design of polymeric container ballasting device and its spacing frames. ^ 9 cl, 2 dwg |
