POLYMERIC AND CONTAINER BALLASTING DEVICE

The proposed technical solution relates to the field of construction of new underground pipelines, including those passing through flooded areas, at the crossings of small rivers, or can be used in the reconstruction and repair of existing pipelines.

A polymer-container ballasting device is known, including containers connected to a pipeline by flexible bridges filled with mineral soil and made with rigid rectangular horizontally arranged frames carrying mounting loops, while the rectangular frames are made of strip and the walls of the containers to the frames are suspended and made of flexible, having openings for water drainage or waterproof material, flexible jumpers are attached to containers at the corners of their rectangular frames, and to the sides of these frames that are not adjacent to the pipeline are pivoting tank lids equipped with hinged panels (SU, No. 769178, 1980).

A further improvement of the polymer container ballasting device described above is an additional technical solution in which the longitudinal walls and bottoms of containers and the flexible bridges connecting them adjacent to the pipeline are made of a single strip of flexible material (RU, No. 1067284, A, 1984).

The closest known is a polymer-container ballasting device containing rectangular stiffening frames, inclined in a trench, upper and lower flexible

rods connected, respectively, with the sides of the frames that are most distant from each other and with the parts of the frames that are least distant from each other, containers made of textile material, nanrimer, TBG-360 (TU 6-06-6-67-87) or TP-110 (TU 6-13-0204024-34-89), the envelope of the frame with the formation of the bottom, front and rear walls of the containers and antirespaces on the walls located on the sides of each tank (ВСН 39-19-003-98 Designs and methods of ballasting and fixing underground gas pipelines, Gazprom, M, 1998, p.6).

Known solutions with sufficient simplicity do not provide the required reliability of their work, for example, during installation on the pipeline and filling with mineral ballast due to the fact that they do not exclude the possibility of filling the trench with ground soil before the ballasting device’s capacity is completely filled, while soil from the outside will prevent full filling of the device’s capacity, which reduces the pace of work, while the design of the side walls does not allow efficient use of the entire volume STI.

The objective of this technical solution is to increase the pace of work and the reliability of the ballasting device, both during installation on the pipeline and in the process of filling with ballast, while increasing the utilization of the useful volume of its capacity, and the manufacturability is ensured by maintaining the simplicity of its design.

The task is achieved in that the polymer container ballasting device comprises made of textile material, for example, TBG-360 (TU 6-06-6-67-87) or TP-110 (TU 6-130204024-34-89), tanks for ballast, bottoms, the front (most distant from the longitudinal axis of the pipeline) and rear (closest to the pipeline) walls of which are formed as one for 2

them with a cloth, lifting loops, stiffening frames, preferably made tubular and inclined in the trench when a ballasting device is placed in it, the upper and lower flexible rods made of textile material, the upper of which are folded at least three times, stitched along their length and are connected by loops formed at their ends with the sides of the frames most distant from each other, and the lower flexible rod is made of a cloth folded in half, at least in a section covering the least distant from each other sides of the frames and stitched transversely on it, moreover, each side of the container is formed by having a lower edge located, preferably freely, in the container, by an insert of textile material sewn along its length to the upper link branch located above the container and, at least in part the length of the section between the upper link and the least distant side of the frame is sewn to the lower flexible link, which is stitched with a panel forming the bottoms, front and rear walls of the ballast tanks. In addition, a single panel forming the bottoms, front and rear walls of the containers is made with slots at the junction of the upper rods and the corresponding sides of the frames into which the hinges of the upper rods are connected. The frames can be made trapezoidal with large bases located on the sides most distant from each other. At the same time, load-lifting loops are located symmetrically along its longitudinal axis and are sewn into a single panel at the sides of the frames that are most distant from each other. The polymer-container ballasting device is equipped with an additional single panel located under a single panel along its length to the lifting loops, the width of which is less than the width of the main panel, with the upper and lower belts and the main and additional single panels jointly sewn in the zone of the transverse axis of the ballasting device.

located in the plane of symmetry of the ballasting device passing through the longitudinal axis of the pipeline. A pair of loops of the upper rods connected (covering) with the corresponding side of the frame farthest from the same side of the other frame is located between the edges of a single panel forming the front walls and the side walls of the container, while the length of the said side of the frame exceeds the length of its opposite side, and an insert made of textile material of one of the sides is sewn along its length to the branch of the upper link located above the container with the formation of a bend of the upper part of it sewn, directed towards the same mu limb stitched portion of the insert other side of the container. In addition, the length of the frame that is farthest from the same side of the frame may exceed the length of its least distant side, preferably by twice the width of the upper link, so that the distance between the loops of the upper links along the length of one side of the frame is not less than the width of a single panel, and the insert is made of textile material sewn to the upper rods from the side of the edges of the upper rods facing each other

Figure 1 presents a General view of the polymer-container ballasting device in the deployed position on the pipeline (in section),

In Fig.2 is a section along aa in Fig.1 (along the rupture line, on the right and left are versions with different lengths of the outermost side of the frame),

In Fig. 3 is a top view of the container capacity in the deployed position of the ballasting device (along the line of tear - options for the different arrangement of the upper rods).

The polymer-container ballasting device contains made of textile material, for example, TBG-360 (TU 6-06-667-87) or TP-110 (TU 6-13-0204024-34-89), containers 1 and 2 for ballast.

The bottom 3, front 4 and rear 5 walls of each tank 1 or 2 are formed by a single panel 6. The device includes lifting loops 7, stiffening frames 8, preferably made of tubular sections connected by a quick disconnect (pin-hole), and obliquely arranged in the trench when placing a ballasting device in it. The upper 9, 10 and lower 11 flexible rods are made of textile material. The upper rods are folded (Fig. 2), at least three times, stitched along their length and connected by the loops 12 formed at their ends with the sides 13 of the frames most distant from each other 8. The lower 11 flexible rods are made of a double folded panel (FigL) at least in the area covering the sides 14 of the frames 8 least distant from each other and stitched transversely on it. Each side 15 of the container is formed by having a lower edge, preferably free, in the container, of an insert 16 made of textile material sewn along its length to the branches of the upper link 9 or 10 located above the container and at least part of the length of the section between the upper link 9 or 10 and the least distant side of the frame 14 - to the lower flexible rod 11, which is stitched with a panel 6 forming bottoms 3, front 4 and rear 5 walls of the tanks 1 and 2 for ballast. A single panel 6 is made with slots 17 at the junctions of the upper rods 9 and 10 and the corresponding sides 13 of the frames 8, into which the loops 12 of the upper rods 9 and 10 are connected. The frames 8 can be made trapezoidal to increase the use of the volume of containers 1 and 2 (Fig. C) with large bases located on their most distant sides 13. The lifting loops 7 are located symmetrically along its longitudinal axis 18 and are sewn into a single panel 6 at the sides of the frames most distant from each other. The polymer-container ballasting device is provided with a length 6 located under a single panel along its length

lifting loops 7, an additional single panel 19, the width of which is less than the width of the main panel 6. The upper 9 and 10 and lower 11 belts and the main 6 and additional 19 single panels are jointly sewn in the zone of the transverse (vertical) axis 20 of the ballasting device located in the plane of symmetry ballasting device passing through the longitudinal axis of the pipeline.

The polymer-container ballasting device (PCBU) for mounting it on the pipeline is suspended by loops 7 to a lifting means, which lowers it along the axis of the pipeline so that the containers 1 and 2 in the process of their deployment are in the open position on both sides of the pipeline, and the device is supported when this would happen with the lower link 11 through the panel 6. In this case, the opening of the containers 1 and 2 occurs due to the rotation of the frames 8 relative to their least distant sides 14, supported through the fabric layers of the lower link 11, the panel 6 (and if necessary - panels 19) on the side surface of the pipeline. The upper links 9 and 10 prevent excessive lowering of the outermost sides 13 of the frame 8 into the trench (i.e., moving the latter to a horizontal or even lower position). The presence of the sides 15 of the tanks 1 and 2 of the inserts 16 (preferably having a bend in their lower part, located in the working position on the bottom 3) allows you to increase the useful volume of the tanks 1 and 2 and to prevent spilling of the mineral material used as ballast outside the tank. The trapezoidal shape of the frames 8 gives the containers the corresponding trapezoidal shape (Fig. 3) of the containers 1 and 2, which simplifies the process of filling them, ensuring the most complete use of their volume. The presence of slots 17 or the placement of the loops of the upper rods at a width exceeding the width of the panel 6, improves the efficiency of use 6

the useful volume of the tank while maintaining the manufacturability of the device, and during installation, loading of ballast and operation of the device - prevents the spontaneous movement of the upper rods 9 and 10 on the sides of 15 tanks 1 and 2.

The proposed polymer-container ballasting device (PCBU) is highly manufacturable, reliable in operation, has capacities whose design allows to increase the amount of ballast loaded into them and, moreover, does not require any significant labor costs in the process of bringing the device into working condition.
