Description

The invention relates to the construction and is used for ballasting with mineral soil transporting gaseous and liquid products of underground pipelines with a diameter of 130-1600 mm laid in waterlogged areas, as well as in wetlands and swamps, in permafrost soils, during reconstruction and overhaul of the linear part of main pipelines laid in conditions of flooded terrain at the crossings of swamps of any category and frozen soils.

The device for ballasting the pipeline polymer frameless textile frameless container (PTBK) is installed on the main pipeline for fixing it at the design level in a full-profile trench.

To fix the pipeline at the design elevation at the angles of rotation of its axis in the plan, at its “hot” sections, as well as the pipeline laid in waterlogged soils and in waterlogged trenches, provided that the pipeline is laid from the berm of the trench with a depth of more than 1.0 m, wetlands, in a peat layer with a depth of at least 2.0 m, at the crossings of streams, small rivers (up to 20 m at low water), river floodplains use a variant of the claimed device for ballasting the pipeline - a textile container (KT-UGV).

The devices ПТБК and КТ-УГВ are designed for operation at an ambient temperature of minus 60 degrees. From to plus 40 degrees. FROM.

A device for ballasting a pipeline is known — a container pipeline weighting agent comprising a pair of connected soft containers filled with soil, located on the pipeline in a position where the longitudinal axis of each tank is parallel to the pipeline and each of which has an end loading sleeve, as well as a pair of loops for suspension to the filling hopper (see RU 2153619 C1, 07.27.2000). This decision was made as the closest analogue of the variants of the claimed device.

A disadvantage of the known device is the need for its installation on the pipeline in a vertical position, followed by a rotation of 90 degrees in the vertical plane, which requires free space between the device to be installed and already installed on the pipeline, that is, the installation of imperceptibly well-known weighting agents on the pipeline is difficult. In addition, filling the bulk of the containers of the known device with bulk material (soil) is carried out in their vertical arrangement, which requires a significant vertical dimension of the hopper - a device for filling the tanks of the weighting material with soil, and this eliminates the possibility of using loaders and excavators with a low loading height.

The solved problem of the claimed invention is the creation of a device for ballasting a pipeline that eliminates these drawbacks, expanding the technological capabilities of the device for ballasting a pipeline, as well as improving the reliability of securing the pipeline at the design level. When implementing the claimed invention, the technical result achieved is:

- simplification of installation on the pipeline of the device by eliminating the operation of its rotation by 90 degrees in the vertical plane and the possibility of gapless installation of the device on the pipeline, which increases the ballast load on the pipeline and improves the reliability of fixing the pipeline at the design level;

- simplification of filling the tanks PTBK and KT UGV bulk material, such as soil, increasing the stability of the device during transportation from the place of filling its containers to the place of installation on the pipeline, as well as when mounting the device on the pipeline;

- it is possible to lay the device on a vehicle during transportation from the place of filling its containers to the place of installation on the pipeline, as well as in places of their storage;

- reducing the vertical dimension of the installation to fill the device’s containers with bulk material, which makes it possible to use loaders and excavators with a low loading height;

- simplifies during the overhaul of the pipeline the dismantling of the device and the release of its containers from bulk material for subsequent reuse of the device.

When ballasting a pipeline laid at the bottom of a full-profile trench, this problem is solved by the fact that the device for ballasting the pipeline — a textile frameless polymer container (PTBK) —contains containers connected by a link and designed to be filled with bulk material — soil, each of which is equipped with a loading sleeve mounted symmetrically on containers by pairs of cargo loops, while in order to expand its technological capabilities in the upper part of each container, a slit hole is open across its longitudinal axis, into which the loading sleeve is sewn, each container is equipped with a pair of additional loops, the last and cargo loops are fixed at the ends of the container, the loading sleeve, cargo and additional loops are located in a vertical plane transverse to the longitudinal axes of the containers and the connections connecting them, and each loading sleeve is made with the possibility of its establishment through the slotted hole in the appropriate container after filling it with bulk material.

In special cases of PTBK, each tank is equipped with a bandage fastened to it, the connection between the tanks is reinforced with textile tapes, PTBK is equipped with additional tapes, the ends of which are fastened with tanks, which limits the collapse of tanks relative to the pipeline, and each loading sleeve is equipped with diametrically oppositely mounted fasteners mounted on it hinges, the number of which is at least two, and reinforced with braid or textile tapes fastened with it.

When ballasting the pipeline at the angles of rotation of its axis in the plan, on its “hot” sections, as well as the pipeline laid in flooded soils and in flooded trenches, provided that the pipeline is laid from the berm of the trench, this problem is solved by the fact that a variant of the claimed device for ballasting pipeline - a textile container КТ УГВ contains connected by connection and intended for filling with bulk material-soil containers isolated from each other, each of which is equipped with a loading sleeve, fixed symmetrically on the containers with pairs of cargo loops, while in order to expand its technological capabilities, a slit hole is transverse to its longitudinal axis in the upper part of each container, into which the loading sleeve is sewn, each container is equipped with a pair of additional loops, the last and cargo loops are fixed at the ends of the container, loading sleeve, cargo and additional loops are located transversely to the longitudinal axes of the tanks and the connections connecting them, each loading sleeve is made with the possibility of its establishment through Spruce corresponding hole in the container after its filling bulk material and the length of connecting said coupling capacitance is not less than half the length of loaded pipeline circumference.

In special cases of performing the UHF CT, each container is equipped with a bandage fastened to it, the connection between the containers is reinforced with textile tapes, and each loading sleeve is equipped with diametrically oppositely mounted fixing loops, the number of which is at least two, and is reinforced with braid or textile ribbons.

The shape and design of the loading sleeves, cargo fasteners and additional loops and their arrangement of a transverse connection connecting the containers of the claimed device ensures a stable position on the load-lifting device of the tanks of the device for ballasting the pipeline, which simplifies their filling with bulk material, increases the stability of the device during transportation from the place of filling it containers to the place of installation on the pipeline, as well as when mounting the claimed device to the pipeline.

Installation of the device on the pipeline is simplified by eliminating the operation of rotating it 90 degrees in the vertical plane and it is possible to install devices on the pipeline without gap, which increases the ballast load on the pipeline and also reduces the vertical dimension of the installation for filling the device’s containers with bulk material, which creates the possibility of using loaders and excavators with a low loading height to fill the capacities of the device. It simplifies the dismantling of the device during the overhaul of the pipeline and the release of its containers from bulk material for subsequent reuse of the device.

Performing a loading sleeve with the possibility of introducing it into the slotted hole of the corresponding container after filling it with bulk material simplifies the design of the device, since it eliminates structural elements that prevent soil from spilling out of the tanks, reduces the lateral size of the device, and provides multi-layer device placement on the vehicle during transportation from the place of filling the containers devices to their place

installation on the pipeline, as well as in places of their storage. In addition, the reduction of the transverse dimension of the claimed device provides a reduction in the volume of earthwork during trench excavation, since the size of the pipeline backfill layer is from the protruding part of the ballasting device.

The location and shape of the hole into which the neck is sewn is made taking into account the distribution of stresses in the wall of the device’s tank filled with bulk material, and also provides reliable fixation of the neck after it is inserted inside the tank filled with bulk material. The implementation of the connecting capacitance of communication with a length of at least half the circumference of the equipped pipeline ensures the placement of the capacities of the CT UGV below the average generatrix of the pipeline, which increases the reliability of its fastening at the design elevation at the angles of rotation of the axis of the pipeline in the plan, as well as in sections of the pipeline where operational displacements, for example temperature (in “hot” sections of the pipeline).

Reinforcing each tank with a bandage increases its load-bearing capacity during multi-layer storage of devices, as well as when the pipeline is located in a deep trench, for example, when crossing gullies and similar obstacles, when the load from the soil of the backfill and heavy construction vehicles passing through it increases significantly.

In the upper part of each tank 1, a slit hole is made transverse to its longitudinal axis, into which a loading sleeve 4 is sewn, designed to fill the tank 1 from a soil filling hopper (not shown) with bulk material, for example, soil. For placement on the nozzle of the filling hopper and for hanging on the said nozzle of the loading sleeve 4, diametrically opposed linking loops 5 are fixed on it, the number of which depends on the size of the device and is at least two. Connecting capacities 1 connection 2 of the CT UGV device has a length of at least half the circumference of the equipped pipeline, which ensures the placement of capacities of the CT UGV below the average generatrix of the pipeline 8. Connecting capacities 1 connection 2 of the PTBK device has a length of less than half the circumference of the equipped pipeline, which ensures the placement of tanks PTBK above the average generatrix of the pipeline 8.

When lowering the pipeline into the tank trench, the UGV CTs are placed below the middle generatrix of the pipeline, while the tanks filled with soil are supports for the pipeline, which lowers the center of gravity of the pipeline system — the device for ballasting the pipeline, increases the anchoring capacity of the system during operational vertical movements of the pipeline in the backfill trenches, increases the reliability of securing the pipeline at the design level.

The design of the claimed device ensures the placement of the longitudinal axes of the tanks filled with soil 1 parallel to the longitudinal axis of the pipeline 8. When dismantling the device, its additional loops 9 allow the tanks 1 to be emptied from the ballasting soil.

The invention simplifies the installation of the device on the pipeline, provides the possibility of a gapless installation of ballasting devices on it, which leads to an increase in the ballasting load on the pipeline, that is, to an increase in the reliability of its fastening at the design level.
