The textile container for ballasting the pipeline contains two containers 1 isolated from each other for filling with ballasting material, formed by side walls 2 made of technical polymer fabric, end walls 3, and upper and lower bases 4, 5, respectively, of different sizes. The containers 1 are interconnected by a flexible connection 6, made with the possibility of installation on the pipe (not indicated, figure 1 coincides with the contour of the upper part of the pipe). Each of the containers 1 has a loading opening with a loading sleeve 7 and cargo loops 8. The lower base 5 of each container 1 is made with a width and area smaller than the width and area of the upper base 4. Each container 1 is equipped with at least one jumper 9, sewn in the internal section between the side walls 2. A flexible connection 6 is made with a length selected from the condition of arranging the base 4 of greater width above the base 5 of smaller width when installing flexible connection 6 on the pipe.

Each tank 1 is made expanding towards the connection with the second tank 1 and faces the middle of the flexible connection 6 with an upper longitudinal base 4 made with a larger width and area than the lower base 5.

The jumper 9 is sewn between the side walls 2 in internal cross sections.

The jumper 9 can be made in the form of a cloth, or in the form of cords, or in the form of woven tapes.

Each tank 1 can be made with at least one jumper 9 in the form of a cloth, close in shape and area to the end walls 3 of the tanks 1.

The capacity can be made with two or more jumpers 9, isolated from each other or connected to each other and located along a broken line (Fig.5, 6).

The container is preferably provided with an additional flexible connection 10 connected to the upper bases 4 of both containers 1 and made with a length not exceeding the diameter of the pipe.

The jumper 9 is sewn to the side walls 2 of the tank 1 or is fixed with loops.

Each tank 1 has one or two loading sleeves 7, which are placed along one of the bases 4 or 5 of the tank 1 and are made with a total passage area of at least 50% of the area of the upper base 4 of the tank 1. Tanks 1 are made with the possibility of installation on the pipe with a horizontal arrangement of longitudinal bases 4, 5 and a vertical arrangement of the end walls 3. In this case, the tanks 1 are made trapezoidal or close to a triangular section with the possibility of installation on a pipe with an inclined side wall 2 from the side ona facing the slope of the trench (not shown).

Cargo loops 8 can be made circular, mounted on the longitudinal walls of 2 containers or attached to the side walls of 3 containers. The loops 8 can be sewn in the middle of the wall 2 or along the edges (shown in dotted lines in FIG. 3).

The side walls 2 can be reinforced with technical fabric or tape. Flexible connection 6 is attached to the corresponding walls 2 (facing the pipe), preferably in their middle part, and can also be attached to cargo loops 8. The loading sleeves 7 are equipped with a braid for tying after filling.

Walls 2-5 can have any geometric shape and corresponding dimensions and can be made integral with each other (from one piece of fabric).

The textile container for ballasting pipelines is operated as follows.

The trench in the case of using the inventive container for ballasting underground pipelines can be performed in the cheapest and fastest way using a bucket wheel excavator with a minimum amount of earthwork.

Tanks 1 are preferably made with a trapezoidal cross-section with a narrower base 5 at the bottom of the trenches. The shape of the tank 1 is provided and stabilized by one or three jumpers 9, for example, trapezoid sewn along the sides 2 inside the tanks 1. The length of the sides 2 of the tank 1 along the pipe is up to 1.5 m, the width of the base 4 on the top is up to 1.3 m, the width of the base 5 on the bottom to 0.6 m, the height of the end sides 3 to 1.5 m for the pipeline with a diameter of 1420 mm, while the area of the two loading sleeves 7 of the tank is about half the area of the upper base 4 of the tank 1.

When backfilling, tanks 1 are spread on the ground, a hopper is installed on them, into which a volume of ballasting material (sand, gravel or other material) is filled, equal to the volume of containers 1 of the container.

After filling the hopper with soil, it rises to a height of 1.7-1.8 m, while the soil is quickly poured into the container 1, and the loading sleeves 7 are tied with braid, ensuring the tightness of the containers 1.

After completion of loading work (tie), the container is lifted and transported to the place of installation and installed on a pipe laid in a trench at the design marks so that the flexible connection 6 rests along the pipeline along the entire length, and containers 1 are laid on the pipeline on both sides with the location of the base 4 of a larger width above the base 5 of a smaller width when installing a flexible connection 6 on the pipe. The flexible connection 10 in this case occupies an approximately horizontal position and does not allow the collapse of the tanks 1 on the sides of the pipe.

After installing containers (weighting agents) filled with ballasting material on the ballasted pipeline, the trench in which the pipeline is placed is filled with soil. The mass of soil above the polymer container provides an increase in its ballasting ability. During operation, loads should be transferred to the ground by the sides of 2 tanks 1 on the sides of the trench. In this position, the pipeline continues to operate under difficult hydrogeological conditions, for example, in flooded areas.

The impact of a flexible connection 6 provides insignificant loads on the insulating coating of the pipeline and its non-deforming walls. During operation, the longitudinal and lateral stability of the position of the container with containers 1 and the pipeline at the bottom of the flooded trench is ensured, since the containers 1 cannot significantly change shape, as well as diverge, wrinkle or twist during transverse and longitudinal pipe movements that are inevitable during changing seasons.

Thus, an effective container for ballasting pipelines was created and the arsenal of containers for ballasting pipelines was expanded.

This ensures the preservation of the shape of the containers after filling with ballasting material, the ability to install in a rectangular trench designed by a bucket wheel excavator, or in a trench with a minimum slope slope and a maximum reduction in excavation volumes, as well as reducing the time for filling container containers with ballast and increasing the reliability of the structure in difficult climatic conditions.
