PIPELINE BALLASTING TEXTILE CONTAINER Russian patent published in 2003 - IPC

FIELD: civil engineering. SUBSTANCE: invention relates to construction, reconstruction and repair of underground pipelines and it is designed for fixing the pipelines on design reference marks. Proposed container contains two soft containers filled with earth and connected with pipeline by ties applied to pipeline. Each container has end face charging hose and pair of load-lifting and additional loops secured on shells of soft containers. To increase load-lifting capacity and strength of container main shell is made of common panel by fastening its cross edges on limited length by preliminary connecting seam, each end face of shell being formed by panel whose bent off edges are preliminarily fastened on main shell. Soft containers are formed by turning central part of end faces of main shell inside with subsequent joining of diametrically opposite straps to form jumper and fastening jumper straps by power seams to form tie applied to pipeline. Longitudinal axes of soft containers are arranged in parallel with longitudinal axis of pipeline when said tie is applied to pipeline. EFFECT: improved reliability of container by increasing strength of connecting seams of bottom plates forming end faces of soft containers. 2 dwg
