The prior art weighting pipeline containing imposed on the pipeline cloth attached to its edges on one side a pair of inclined rigid framework associated with them and filled with soil containers made of flexible material in the form of membranes, as well as flexible jumpers, United ends with a free side of each of the frames (see EN 2062938 WITH, 27.06.1996, F 16 L 1/06). This decision was taken as the closest analogue of the claimed invention. A disadvantage of the known solutions is the occurrence of wedge-shaped gaps on both sides of the pipeline between adjacent weights when they are continuous (group) is installed on the pipeline. Since in the known solution tank filler formed from cloth, flat dimensions equal to the dimensions of the frame, then under the action of Nasya, and transverse edges of the cloth, pressed the middle part to the pipeline, due to stretching of the cloth deformed, bent. The largest deformation of the cloth arise in its corners. This leads to the spilling of the ballasting of the soil in the resulting gaps and reducing the total weight of the ballast group weights. In addition, in the absence of clear overlay panels pipeline may damage its insulation coating under the influence of atmospheric factors - the destruction of insulation from exposure to radiation of the sun, and the subcooling of the pipeline, which causes a change in the temperature regime of the pipeline and its temperature deformation or displacement of pipeline with a design mark. In addition, the mounting of the ballast on the pipeline in the field is difficult, especially when ballasting pipelines of large diameters, due to ethnological Assembly rigid framework.

The problem solved by the invention is to remedy these disadvantages - increase of efficiency of use of soil ballasting and increase manufacturability and Assembly works and reliability ballasting of the pipeline.

This task is solved in that in poprelayd to the pipeline bottom longitudinal load-bearing sides of the rigid framework, imposed on the pipe connected with the bottom longitudinal load-bearing sides of the rigid framework of the power belt in the form of a flexible cloth associated with frames filled ballasting soil containers made of flexible material, and holding the rigid frame inclined and United at their corners with the upper longitudinal bearing sides of the transverse pipe flexible jumpers, fastened his middle in the zone of the longitudinal axis of symmetry with the power belt. The device is equipped with transverse end walls, tanks for ballasting ground and power belt is made in the form of a single bending around the bottom of the lower longitudinal load-bearing side frame panels, the longitudinal side of which is connected to the upper longitudinal bearing sides of the inclined part, with the longitudinal size of a panel exceeds the longitudinal size of the hard part, the latter is made collapsible, provided with a transverse spacer elements, the connection of the longitudinal sides of the framework with flexible jumpers, as well as the connection of the upper and lower longitudinal sides of the frame with the panel power belts are made with eyelets, with transverse end walls bonded with flexible jumpers, go around the outside cross the I it has a more flexible jumpers, located between the transverse strut elements rigid framework which is necessary for large longitudinal size of the weighting agent to a uniform distribution on the pipeline ballasting weight of soil weighting agent.

Each of the lugs connecting the power belt with upper and lower longitudinal sides of the framework, formed sewn to the cloth folded in half lengthwise strip of flexible material similar to the material of the cloth power belts, and connecting the power zone, and a flexible jumper from the upper longitudinal carriers parties to the framework of the lugs is formed by bending with firmware longitudinal edges respectively of the flexible panel power belts and the ends of the flexible jumper.

In the particular case of performing weighting connecting the power belt from the bottom longitudinal load-bearing sides of the framework of the lugs is formed by bending and firmware with the power belt longitudinal edges of the additional imposed on the pipeline flexible cloth, which is fastened with its middle in the zone of the longitudinal axis of symmetry with the power belt.

It is possible to perform weighting, when the edge of the additional imposed on the pipeline flexible sheets bonded with the power belt in the zone of promixity to the power belt.

To improve the manufacturability of the Assembly in the field in the weighting of the connection of the transverse spacer elements with longitudinal bearing sides of the rigid frame carried by the sliding coupling with the possibility of their movement by the spacer elements and locking pins in holes formed respectively in the spacer elements and bosses welded to the longitudinal bearing sides of the hard part.

In the particular case of performing weighting of the upper longitudinal load-bearing side of the hard part and lugs are made of square tubes, which simplifies the manufacturing process of the elements of the hard part.

The longitudinal load-bearing side of the hard part is movable from tubular elements and their connection through the outer sliding sleeves or inner cylindrical inserts with the possibility of moving along the longitudinal bearing sides of the frame and fixing the pins in the holes formed respectively in the joined elements of the longitudinal sides of the hard part.

The presence of transverse end walls of the weighting guarantees the elimination of flowing soil ballasting weights in their group setting, even in the presence of MES which allows full use of his weight ballasting pipeline adequate protection of its insulating coating and maintaining the temperature of the pipeline.

The invention is illustrated by the graphic material, where Fig.1 shows the device after filling his ballasting soil; Fig.2 - the same, top view; Fig.3 connection elements rigid framework of Fig.4 - execution of the eyes.

The device has imposed on the pipeline 1 power belt is a flexible panel 2. Transverse flexible jumpers 3 and the panel 2 is connected by its means 4 to form a unified fabric part of the weighting. The panel 2 is connected with the lower bearing longitudinal sides 5 rigid 6 eyelets 7 and the longitudinal edges of the panels 2 are connected with the respective upper bearing longitudinal sides 8 rigid framework 6. The longitudinal bearing face 5, 8 rigid frame 6 is movable from tubular elements and their connection through the outer sliding clutch 9 or the inner cylindrical inserts 10 can be moved along the longitudinal bearing sides and fixing pins 11 in the holes formed respectively in the joined elements of the longitudinal sides of the rigid framework. The connection of the transverse spacer elements 12 with PR who move through the spacer elements and the fixing pins 11 in the holes, performed respectively in the spacer elements and the bosses 13 which are welded to the longitudinal bearing sides of the rigid framework. Rigid frame 6 are power bearing elements of the containers 14 weighting. Containers 14 are formed by placing mineral ballasting ground 15 on the panel 2 due to the fact that the longitudinal size of the latter exceeds 0.4-0.6 m corresponding to the size of the longitudinal sides 5, 8 rigid framework 6, and also due to the elastic deformation of the cloth 2. Transverse relative to the longitudinal axis of the pipeline, the size of the cloth ensures a stable position of the weight on the pipeline, wherein the rigid frame 6 contact the bottom side 5 with the surface of the pipe below its horizontal diameter. Preferably the placement of the parties 5 part 6 as close as possible to the bottom of the trench, but without contact with him, in order to provide a fully transfer the weight of the soil backfill weight on the pipeline. The ratio of the lengths of the lateral sides of the panels 2 and the flexible jumper 3 provides accommodation of part 6, in which their longitudinal sides 5, 8 do not protrude above the top of pipe 1. Such placing of the filler does not cause increase in the volume of earthworks (see SNiP 2.05.0 the new belt. To the edges of the flexible jumper 3 attached to the upper edge of the end walls 16. Cloth, flexible jumpers and end walls are made of technical fabrics.

The device can be shown on the example of immersion in the soil surfaced section of the pipeline, such as pipeline (see Fig.4). On the emerged part of the pipeline hang a group of unfilled weights, it is possible bond between them adjacent sides of the rigid framework. Make filling mineral ballasting ground cloth 2 weights. Under the weight ballasting ground cloth elastically deformed and by exceeding their longitudinal dimension over the appropriate size of the hard part in the last-formed containers. The volume of soil accommodated in a separate weighting depending on the pipeline diameter is from 1.0 to 2.0 cubic meters per peg.m of the pipeline. The total load from the ballasting of the soil is passed through the panel - power belt weighting in the pipeline and he is immersed in a flooded trench. The invention eliminates possible damage to the surfaced of the pipeline insulation coating under the influence of atmospheric factors - the destruction of the insulation of the pipeline in which the change in the temperature regime of the pipeline and its thermal deformation. Thus, the invention is producible in the manufacture, due to their low weight and easy Assembly convenient to use and effective for various laying and operation of pipelines for different purposes.
