Abstract

Usage: in construction. SUMMARY OF THE INVENTION: bonded shells of synthetic material are filled with mineral soil. Each shell is provided with enclosed strips covering it in the transverse plane and closed to it with a length exceeding the circumference of the shell. The non-sewn part of each strip forms a loop. The connection of the shells is made in the form of tapes threaded through non-sewn parts of the strips and tied in a knot. The length of the sewn strip is 0.25-0.5 of the circumference of the shell. 2 ill.

Description

The invention relates to the field of construction, in particular to the design of pipeline ballasting devices.

Various designs are used for ballasting pipelines against ascent, for example reinforced concrete reinforcements, anchor devices, etc.

A well-known structure of a yellowing system, including containers connected by flexible bridges placed on pipelines made of rolled synthetic material filled with mineral soil, while the walls of the containers are suspended from rigid frames. This design is undesirable and cumbersome to operate, since it requires very carefully to observe the equilibrium condition of the containers when filling them with soil, while the soil should be only mineral.

Utilizers are known in which rolled synthetic materials are used as spacers between a pipeline and a backfill soil .: ; g

Closest to the claimed invention is a pipe liner comprising interconnected shells of synthetic material filled with mineral soil 1.

The disadvantage of this desirability is the difficulty of manufacturing. Sewing the casing and filling it with soil requires special equipment.

The purpose of the invention is to reduce the laboriousness of fabricating a vaporizer by unifying ballast elements.

This goal is achieved by the fact that in the pipe liner comprising connected shells of synthetic material filled with mine X |

ground, each of the shells is provided with at least two enclosed strips covering it in transverse planes and partially sewn to it having a circumference of the shell. At the same time, a part of each closed strip is not sewn into a loop, and the connection of the shells is made in the form of tapes threaded through unattached parts of the bands AND closed by S. -. .NODES.

The length of the received part of each strip is 0.25-0.5 of the circumference of the shell.

Figure 1 shows the utiliter mounted on the pipeline; figure 2 - its cross section ..

The appliance contains placed on opposite sides of the pipeline 1 interconnected and made of synthetic material shell 2 filled with mineral soil. Each of the shells 2 is provided with two closed strips 3 covering it in the transverse planes and partially sewn to the shell 2 with a length exceeding the circumference of the cross section of the shell 2; In this case, a portion of each closed strip 3 is unprotected to form a loop, and each communication 4 of the shells is made in the form of tapes threaded through the non-sewn parts of the strips and tied in knot 5.

The length of the sewn part of each strip is 0.25-0.5 of the circumference of the shell. The distance between the closed strips of the shell is determined from the condition of equilibrium of the structure.

The inventive customer is made of high tensile fabric synthetic roll materials such as TK. TBG, TP and non-woven synthetic materials such as Terfil. Svteks et al. All connecting seams of the device are stitched, i.e. under stationary conditions x.

Each shell consists of a body and two bottoms. A sheath with one sewn-in bottom and sewn closed bands is supplied on the cable. The second bottom is just stuck. Before mounting on the pipeline, the shell through an unstitched bottom is filled with soil while vibrating the shell, and then the bottom is sealed. After that, the shells are connected in pairs by means of a tape tie threaded into sewn closed strips. The tape is tightened with a knot, the UTEL lighter is suspended by closed strips on the beam and lowered into the pipeline.

As a specific design, we present the UBPTs-700 heater made of material of the TBG-360 type for a pipeline with a diameter of 720 mm.

The utensil is made of roll stock and is 1450 mm wide. thus, the shell length is 1450 mm. The diameter of the bottom is 750 mm. Two closed stripes

120 mm wide and 2600 mm long is sewn at a distance of 750 mm from each other and 350 mm from the bottoms. The strips are joined by overlapping stitching, stitching the strip with several seams.

Unfilled shells can be made in industrial centers. Their transportation over a large distance does not require powerful loading and unloading means, a large number of heavy vehicles; mineral filling can be carried out adjacent to the track. In addition, scarce materials such as cement and metal are not required for the manufacture of welders.

In order to increase the ballasting capacity of the gel, it is made of three or more shells.
