FIELD: construction, pipeline.
SUBSTANCE: invention is related to construction and is used in erection and repair of underground and overground pipelines. Two opposite sets of tanks that are isolated from each other connected by flexible power belts with the possibility of their imposition on pipeline and intended for filling with loose material are linearly installed on both sides of pipeline. Every set of tanks is arranged in the form of single-row cellular structure open from top, side walls of which are made by punching two cloths previously folded and made of flexible textile material with fastening seams. Fastening seams are located perpendicular to long sides of cloths, and bottom is formed with long slated seam. Every cell is equipped with lifting lugs. Invention makes it possible to eliminate loading sleeves preserving loader charging function, provides for higher throughput capacity of equipment during loader charging with sand.
EFFECT: higher reliability of pipeline ballasting due to increase of pipeline linear load, simplification of pipeline group ballasting, higher reliability of pipeline insulation preservation during its operational shifts.
