FIELD: construction. ^ SUBSTANCE: device for ballasting of pipelines comprises a pair of reservoirs having side walls formed by flexible sheet material, which is single for both reservoirs, with an intermediate section between reservoirs, containing layers joined to each other, which are formed by its end sections laid onto the central section of the flexible sheet material and arranged at one side from it. End sections are additionally folded to form bends. An edge-adjoining part of the end section that is directly applied onto the flexible sheet material is bent to outside, and an edge-adjoining part of the other end section is tucked up under it. ^ EFFECT: when using the invention, the device reliability increases due to strengthening of the intermediate section with simultaneous simplification of its design, it become possible to use, if required, strong joints that withstand high rupture loads. ^ 8 cl, 50 dwg |
