TEXTILE CONTAINER FOR BALLASTING PIPELINES (VARIANTS) Russian patent published in 2004 - IPC

FIELD: pipeline construction technology. SUBSTANCE: device has two soft enclosures, connected by a link placed on pipeline and filed with soil. Each enclosure has end loading sleeve and couples of load hoisting loops. Of one panel of technical material main manacle ring is formed by connecting transverse edges of plane by connecting seam. Lower end of main manacle ring is formed of the plane, connected by folded edges to main manacle ring. Soft enclosures are made by unfolding central portion of main manacle ring lower end to the inside with later engagement of its diametrically opposite strips to form a cross connection, and connection of cross connection strips by reinforcing seams with forming of a link placed on pipeline. Mouths and adjacent edge of a link placed on pipeline are reinforced by a strip, connected to them along textile container perimeter. Longitudinal axes of soft enclosures are placed in parallel to longitudinal axis of pipeline. Reinforcing strip is made 8-shaped, it rounds mouths with passing onto opposite sides of a link placed on pipeline, for which purpose elongated apertures are made in the latter near mouths. Each sleeve is provided with closing means. EFFECT: increased ballasting reliability. 2 cl, 2 dwg
