Description

The utility model relates to the construction of pipelines and can be used for ballasting the pipeline to ensure its stable position at design elevations.

Known weighting of the pipeline, containing two plate blocks, based on the bottom of the trench. The blocks are made with mounting loops on their surface for fastening using a power belt on the pipe - RF patent №2066807, F16L 1/06, 1996

The disadvantage of this device is its instability, because with a large steepness of the slopes of the trench and large dimensions of its bottom, it is difficult to control the symmetrical laying of the blocks relative to the pipeline, which leads to their distortion during installation, and when lowering the pipeline, transverse forces arise, pushing the weighting blocks to the sides. Thus, the blocks work separately from the pipeline when it is extruded by soil to the surface.

The prototype is a device for ballasting a pipeline using ballasting blocks of the base, attached to the bottom of the pipeline and laid on the bottom of the trench along with the pipeline - autosvid. USSR No. 373477, F16L 1/06, 1973

The disadvantage of the prototype is that the position of the pipeline on the ballasting blocks under certain conditions can lead to the ingress of water between the pipeline and the ballasting block, as a result of which the pipe will be ejected from the ballasting blocks and the belts will break or the pipeline will shift horizontally.

In this regard, the problem solved by the options of the utility model is to improve the weight characteristics, which ensures the reliability and quality of the stable position of the pipeline.

This problem is solved by two device options.

In the first embodiment, the device for ballasting the pipeline contains two weighting materials in the form of the first and second containers with sand, the first of which is placed at the bottom of the trench and is connected to the second container located on the upper part of the pipeline through mounting loops with tie straps.

Coupling belts can be made of polypropylene or polyester material.

In the second embodiment, the device for ballasting the pipeline contains two weighting materials, one of which, in the form of a container with sand, is placed on the upper part of the pipeline and has mounting loops for connecting to the second weighting material, made in the form of an isosceles trapezoid with a saddle in the middle of the larger side, in which sand cushion for laying the pipeline, and the smaller side of the weighting is placed at the bottom of the trench.

Here, as in the first embodiment, the coupling belts can be made of polypropylene or polyester material.

Figure 1 presents the first embodiment of the device, figure 2 - the second option.

The device for ballasting the pipeline according to the first embodiment (figure 1) contains two weighting materials: a first container 1 with sand and a second container 2 with sand. The container 1 is placed on the bottom of the trench 3 and is connected to the container 2 located on the upper part of the pipeline 4, through the mounting loops 5 with tie straps 6, which are made of polypropylene or polyester material. These belts withstand heavy loads and ensure the constancy of their length when wet.

The device for ballasting the pipeline according to the second embodiment (figure 2), as in the first embodiment, contains two weighting materials:

the first is in the form of a container 7 with sand and the second weighting agent 8. The container 7 is placed on the upper part of the pipeline 9. The weighting agent 8 is usually made of reinforced concrete, the shape of which is in the form of an isosceles trapezoid with a saddle 10 in the middle of the larger side, in which the sand a pillow 11 for laying the pipeline 9. The smaller side of the weighting agent 8 is placed at the bottom of the trench 12.

The container 7 is connected to the weighting agent 8 through mounting loops 13 with tie straps 14, which are made of polypropylene or polyester material, the positive properties of which were noted above.

Thanks to two weighting agents: a container 7 with sand and a weighting agent 8 having a trapezoidal shape and the indicated location relative to the pipeline 9, the pipeline occupies a stable position in the trench 12, which practically eliminates the possibility of its expulsion by the soil to the surface.

The organization and production technology of the work with the device proposed in the second embodiment is as follows.

The leveling of the bottom of the trench 12 is carried out along the entire length of the route, after which the weighting agents 8 are laid using an automobile crane or a pipe-laying crane. A sand cushion 11 is poured onto the saddle 10 of the weighting agent 8, on which the pipeline 9 is laid.

Then, the container 7 is laid on the upper part of the pipeline 9 and is connected to the weighting agent 8 through the mounting loops 13 with tie straps 14.

Then the final filling of the trench 12 with soil is made.

The production technology of the first option is similar.

This provides a solution to the problem of increasing the weight characteristics, which improves the reliability and quality of the stable position of the pipeline.
