The invention relates to construction and is used for laying pipelines in Ottaway permafrost and obvodnennyh territories. The prior art method of construction of the pipeline in flooded soils. On laid on the bottom of the trench the pipeline hang soft cloth, edges of which are stacked in advance in 2-3 layers and fixed in this state by mechanical tack or surface melting. Ready reinforcing mats of the bars are released into the trench spikes down, directing the latter to the closure wall and the bottom of the trench, folded at the fold edge of a soft cloth. Partially downloading reinforcing mats of its own weight after contact studs with folded at the fold edges soft panels, push past the spikes, then continuing to lower the opposite ends of the bars, stack reinforcing mats on a soft cloth. The trench is filled with soil backfill to the surface of the roller. Soil to fill the trench picked up from the dump, filled the trench, moving it with the help of a bulldozer. In the event of flooding of the trench the pipeline experiences the action of buoyancy force, which causes some displacement of the pipe up. Together with the pipeline raised areas with a soft cloth covering the pipe from above. castke soft cloth, underneath reinforcing mats from bars and fastened to them by means of thorns, deprived of the opportunity to move. Therefore, the process of lifting the pipe under the action of the buoyancy of the water is accompanied by tension hanging from the pipe sections with a soft cloth and turn reinforcing mats with inversion of ground spikes. Since the material of the panels has a relative elongation, loss ballasting capacity of the panels and may be offset pipeline project marks under the action of the buoyancy of the water (see SU 1809226 A1, 15.04.1993).

The prior art method of laying underground pipeline to obvodnenii site (see SU 1013689 And 23.04.1983).

According to a known method, to produce the passage of the trench with education on the calculated distances from each other of the symmetric broadening of the trench, and then the overlap of the berm (at Bay), the walls and bottom of the trench to host pipeline continuous flexible carpets, the width of which no more than the length of the broadening in the direction of the axis of the trench. In conclusion, make the trench and the broadening ballasting material, including excavated soil. To increase the reliability of the crushing edge solid areas of carpets broadening perform with a bottom having a slope away from the bottom of the trench. who, if necessary, accommodate technological road on the berm of the trench during the implementation of its broadening in long trenches branches to the passage of the trench with its symmetrical broadening and backfilling are in two stages, the first of which make the passage halves of the broadening of the trench and backfill on the runway technological road. The backfilling perform the following otryvnoi, and before filling in each half broadening put marginal land rolled continuous carpet. This allows you to mount the piping directly on the berm of the trench, and then lowered into the trench.

Thus, in the result, the possibility of crushing the regional solid areas of carpet soil is provided to secure the pipeline on the bottom of the trench. The disadvantage of this method is the lack of reliability crushing soil backfill the edges of the flexible carpets, especially at low altitude layer of soil backfill, since the latter is quite loose, naliases and its holding capacity is provided only by friction at the boundary surfaces of a flexible carpet - ground".

There is a method of laying a pipeline, which is used in the construction of pipelines on obvodnennyh territories. The method is as follows. In the case of flexible carpets with improved deformation properties at the bottom of the broadening perform the pits, filling the broadening of the soil is flexible fit carpet to the bottom of the broadening and pits. In the presence of water in the hole is the bottom of the broadening perform with the estimated slope in the direction of the pipeline, this thickening is located above the water level. During the construction of the pipeline in permafrost soils of the end sections of the flexible carpets placed outside the areola thawing of the soil, i.e. they are permanently frozen soil. As a material for flexible carpets can be used fabric for pipeline ballasting TBG-360, cloth stitch-container "Ponton".

Thus, the pre-stretching flexible carpets makes better use of their mechanical properties on ballast piping and eliminates the instability pregrada effort from operational hoods flexible carpets (see SU 1638419 A1, 30.03.1991). This solution is the closest analogue to the claimed group of inventions - variation method. The specified decision has the above disadvantages is to increase ballasting ability to increase resistance to pulling the edges of the flexible carpets from soil, which can be provided by increasing the length of a fixed-fixed ground edges of the flexible carpets, increasing the height of the backfill, the use of compaction of the backfill, the increase in the force of drag when pulling end sections of the flexible carpet from soil and backfilling the trench.

The closest known solution to method a ground strip of the pipeline is a pipe-laying the wire into the embankment, when the lower generatrix of the pipe is stamped on the level of the surface or above it when pipe laying on the ground cushion (see BORODAVKIN P.P. and other "Construction of trunk pipelines", Moscow, Nedra, 1987, page 15, Fig. W.

Objective of the claimed group of inventions is to improve the reliability of the fastening of the pipeline on the project marks when it is laid in the trench obvodnenii periodically, in a trench with a high level of standing water, under ground pipe laying on obvodnenii territory. Achievable technical result in the implementation of a group of inventions is increasing clamps capacity of soil backfill when using flexible carpets for ballasting and consolidation pipeline project marks.

This task is solved in that in the method of laying underground pipeline tear trench with education based on the calculated distance from each other of the symmetric pairs of the broadening of the trench. Lay the pipeline on the bottom of the trench, transversely overlapping the flexible carpets pipe, the bottom of the broadening and the bottom of the trench in the vicinity of the broadening pinch equipped with eyelets and ankerwyke elements peripheries flexible carpets and produce backfill of the trench. To improve the reliability of the fastening of the pipeline through the Uwe is icene clamps abilities boundary plots flexible carpets in the soil as ancarola items used are posted in the eyes is parallel to the pipe filled with soil cylindrical containers textile, in the center flank areas flexible carpets with eyelets made perpendicular cuts. Before jamming boundary plots flexible rugs each rug pull and fix the tension and pre-stretching flexible carpets with pockets is carried out at a filling broadening the ground, providing a flexible fit carpet to the bottom of the trench. In addition, the bottom of the broadening of the trench is performed with the calculated slope in the direction of the pipeline or from him. Backfill the soil of each pair of the broadening and trenches are in the direction of the pipe and symmetrically with respect to the pipeline.

This problem is solved in the method of laying underground pipeline in the trench with a high level of standing water, which consists in the passage of the trench with education based on the calculated distance from each other in pairs symmetric with respect to the line broadening of the trench, laying the pipe on the bottom of the trench with cross overlapping flexible carpets pipeline and trench locations broadening, pinched in the Bay, equipped with eyelets and ankerwyke elements flank areas flexible carpets, and backfilling the trench in which to improve the reliability of the fastening of the pipeline in a flooded trench pairs symmetric with respect to the line broadening of the trench tear on CH is Bina, not exceeding the water level in the trench, before overlapping flexible carpets pipe alloy or placed in a flooded trench, for its diving and laying on the bottom of the trench as ancarola elements in the broadening use posted in the eyes is parallel to the pipe filled with soil cylindrical containers textile, before jamming boundary plots flexible carpets each of the boundary sections pull locking tension, initial tension with the formation of pockets carried out at the filling of the Bay and the trench material by immersion of the pipeline, ensure the fit of the pipe and flexible carpet to the bottom of the trench, and backfilling with soil each pair of the broadening and trenches are in the direction of pipeline and symmetrically with respect to the pipeline, while in regional areas flexible carpets on the depth of the lugs perform pre-perpendicular cuts.

In addition, the bottom of the broadening of the trench is performed with the calculated slope in the direction of the pipeline or from him.

This problem is solved in the method of construction of the onshore pipeline on obvodnenii territory, which consists in laying a pipeline on the surface of the soil or prepared on it base, docked at the design position of the pipeline refers is some dirt mounds, in which to improve the reliability of the fastening of the pipeline on obvodnennyh sites on the calculated distance from each other symmetrically with respect to the pipeline tear in the ground a couple of pits, transversely overlapping the flexible carpets pipeline, slopes and bottom of the pits, pinch them in the soil backfill is supplied with eyelets and ankerwyke elements peripheries flexible carpets, and as ancarola items used are posted in the eyes is parallel to the pipe filled with soil cylindrical containers of textile, in this advance in marginal areas flexible carpets on the depth of the lugs perform perpendicular incisions, before jamming boundary plots flexible rugs each of them pull locking tension, and preliminary the calculated tensile flexible carpets is carried out at a filling pits with soil, at the same time provide a flexible fit carpet to the bottom of the pits, and the backfill soil of each pair of pits are in the direction of the pipe and symmetrically with respect to the pipeline. The distance between pits in a pair is not more than the diameter of the pipe and not less than the width of his bed. In addition, the bottom of the broadening of the trench is performed with the calculated slope in the direction of the pipeline or from him.

This problem is solved in the method of laying on the roadways pipeline obvodnenii territory, which consists in laying a pipeline on the surface of the soil or prepared on it base, docked at the design position of the pipeline by dumping dirt mounds in which to improve the reliability of the fastening of the pipeline on obvodnennyh sections symmetrically with respect to the pipeline transversely overlapping the flexible carpets pipe and the ground surface, the edge sections of the flexible carpet is stretched and fixed their pull, pinch ground dumping mounds with eyelets and ankerwyke elements peripheries flexible carpets, and a preliminary design of the tensile flexible carpets is carried out at the dumping ground of the embankment, at the same time provide a flexible fit carpets to the ground surface, and filling the embankment lead in the direction of pipeline and symmetrically with respect to the pipeline, and as ancarola items used are posted in the eyes is parallel to the pipe filled with soil cylindrical textile containers, and in marginal areas flexible carpets, at the depth of the lugs perform perpendicular cuts.

This task is solved in that the device for anchoring a pipeline containing imposed symmetrically on the pipeline section of flexible carpet, each parallel to the pipeline, CR the eve portion of which is equipped with a bar and contains placed it parallel to the pipe anerousis longitudinal element. As ancarola elements are filled with soil cylindrical containers textiles, and in marginal areas of each flexible carpet perpendicular to the eyelets are made of at least one incision to a depth of eyes.

At the same time as the flexible material of the carpet is technical fabric with a relative elongation at break 15-38%.

The invention is illustrated by the graphic material, in which figure 1 shows a pipe laid in the trench and secured with calculation step flexible carpets; figure 2 - same as figure 1, but with a high level of standing water; figure 3 and figure 4 - land of the laid pipeline.

The way in part of independent claim 1 is as follows. Trench 1 tear off double Bay 2 on both sides, the dimensions of the broadening is determined taking into account the diameter of the pipe 3, properties of soil backfill 4 and the mechanical properties of flexible carpets 5.

Across the line 3 in each pair of Bay 2 stack segment flexible carpet 5, while the middle part of it touches the top of the pipe 3. Each of the boundary sections of the flexible Mat 5 is made with an eye 6, which is threaded parallel to the pipe 3 anerousis element 7 - textile container. One of the edge sections of the flexible Mat 5 is fixed on the bottom of the broadening of 2 inventory pins 8, the flexible Mat 5 n is Thibaut and fix the other regional plot of pins 8, then a flexible Mat 5 is covered with soil 4 to a length of 1-1,5 m, providing a seal to the bottom of the pits flexible Mat 5 with its pre-stretching, and backfill soil of each pair of the broadening and trenches are in the direction of the pipe and symmetrically with respect to the pipeline. Pins 8 extract and complete the filling of the Bay 2 ground 4. Under the weight of the soil backfill flexible Mat 5 receives the preliminary stretching with providing fit flexible carpet 5 to the bottom of the broadening 2 and trenches 1.

Pre-stretching flexible carpets creates additional effort, pregrade pipeline, which is especially important in flooded trenches during the first 3-5 years of operation of the pipeline, when the soil backfill is not bridge, harden, clog and ballasting ability is low.

The implementation of the broadening with a slope of bottom in the direction of the pipeline will provide close to the vertical position of the branches of the carpet adjacent to the pipeline, which creates favorable conditions for the work of the branches of the carpet stretching and allows you to attach to the pipeline additional vertical restraint of the tensile stress flexible carpets.

The implementation of the broadening with the slope of the bottom of the pipeline allows to increase the thickness of the layer of backfill soil over the marginal areas of the flexible Mat and thus increase clamps force his ugruna. The choices run the bottom of the pit depends on the diameter ancarola elements, from the degree of flooding of the trench and the type of soil backfill.

Running in the longitudinal edges of the carpet material sections perpendicular to the lugs on all their depth, facilitates the introduction of lugs ancarola elements, particularly when a substantial width of the carpet, when every eye is placed linearly several textile containers on the entire width of the flexible carpet.

As the material of the flexible carpets use technical fabric of polyamide or polyester materials. This fabric comes ruanruan with the greatest width equal to 3 m If necessary, the cloth depending on the type of material stitched transverse or longitudinal trim seam. These materials have a relative elongation at break 18-38%. Pre-stretching for the specified materials, respectively 30-50% of their relative elongation at break and does not exceed the estimated operating lengthening flexible carpets. For example, for fixing a pipeline with a diameter of 1420 mm in obvodnenii trench depth of 2.6 m requires flexible carpets size 6 × 9.8 m, the length of the pair of broadening is 7.5 meters

Clamps capacity of soil depends on its type, humidity and thickness of the backfill layer, i.e. from the bottom to the material world. As a result of the research showed that the maximum force of the clutch carpet material with the soil at the depth technical fabrics at 1 m is kg/square feet:

- sand natural moisture 1200

- sand watered 550

- clay in meters condition 1350

- clay in a viscoplastic state 400

It is established that these efforts clutch technical fabric flexible carpets and soil increase in proportion to the depth of the carpet material and the thickness of the backfill layer is 2 m above magnitude increase in 2 times.

Use as ankerwyke element of textile container greatly increases the drag force pulling the carpet material from the soil backfill under the influence of the buoyancy of the water or under operational progress of the pipeline, because anerousis element has a large surface area drag force is pulled. In addition, in the present manufacturing technology textile containers is well developed, and they are widely used in the construction of trunk pipelines as ballasting or supporting elements.

To improve the reliability of the fastening of the pipe 3 in a flooded trench 1 pairs symmetric with respect to the axis of the trench and pipeline of the broadening of the trench tear to a depth not exceeding the water level in the trench. Before overlapping flexible rugs 5 pipe alloy or placed in a flooded trench. For its diving and laying on the bottom of the trench as ancarola elements 7 in the broadening use posted in the eyes is parallel to the pipe filled with soil cylindrical textile containers. Before jamming boundary plots flexible carpets each of the boundary sections pull locking tension inventory pins 8. Preliminary design tensile flexible carpets carry out filling of the Bay and the trench soil with simultaneous immersion of the pipeline. At the same time provide a good contact between the pipe and flexible carpet to the bottom of the trench, and backfilling with soil each pair of the broadening and trenches are in the direction of the pipe and symmetrically with respect to the pipeline.

Consolidation in the design position of the pipeline is performed by filling a dirt mound 11.

To improve the reliability of the fastening of the pipeline on obvodnennyh areas previously calculated distance from each other and symmetrically with respect to the pipeline tear in the ground a couple of pits 12. The distance between the pits in the pair is not more than the diameter of the pipe and not less than the width of his bed.

Possible passage bulldozer one pit length is equal to the sum of the lengths of the pits 12 and the filling in the middle of the base of the pipeline.

Transversely overlapping the flexible rugs 5 line 3, the base and the bottom of the pits, which are placed flexible segment of the Mat 5, while the middle part of it touches the top of the pipe 3. Each of the boundary sections of the flexible Mat 5 is made with an eye 6, which is threaded parallel to the pipe 3 anerousis element 7 - textile container. One of the edge sections of the flexible Mat 5 is fixed on the bottom of the pits 12 inventory pins 8, the flexible Mat 5 pull and C is kreplach other regional plot of pins 8, then a flexible Mat 5 is covered with soil 4 to a length of 1-1,5 m, ensuring adherence to the slopes and the bottom of the pits flexible Mat 5 with its pre-stretching, and backfill soil of each pair of pits and dumping mounds 11 lead in the direction of the pipe and symmetrically with respect to the pipeline. Pins 8 extract and complete backfilling of pits 12 soil embankments 11.

Backfill the soil of each pair of pits are in the direction of the pipe and symmetrically with respect to the pipeline to create a flexible branches carpet symmetric efforts, in addition pregrada the pipeline. Pins 8 extract and complete backfilling of pits 12 soil. Under the weight of the soil backfill and soil embankments flexible Mat 5 receives the preliminary stretching with providing fit flexible carpet 5 to the slopes and the bottom of the pits 12.

Variant of the method a ground pipeline of independent claim 11 of the formula is as follows. After preparation of the track and the base of the pipe stack it above the ground surface 9 or prepared it the base 10, the lower forming pipe 3 has etco on the level of the surface or above if the pipeline is laid on the ground cushion - base 10. Consolidation in the design position of the pipeline is performed by filling a dirt mound 11. Pre transversely overlap the pipe 3, the base and the surface of the soil 9 laying the flexible segments of the Mat 5, and the middle of each of them touches the top of pipe 3. Each of the boundary sections of the flexible Mat 5 is made with an eye 6, which is threaded parallel to the pipe 3 anerousis element 7 - textile container. One of the edge sections of the flexible Mat 5 is fixed on the surface of the soil inventory pins 8. Flexible Mat 5 pull and fix the other regional plot of pins 8, after which the flexible Mat 5 is covered with soil mounds 11 for a length of 1-1 .5 m from ancarola elements 7. Backfill the soil of each pair of edge sections of the flexible Mat 5 lead in the direction of the pipe and symmetrically with respect to the pipeline to create a flexible branches carpet symmetric efforts, in addition pregrada the pipeline. Pins 8 extract and complete filling of the embankment 11. Under the weight of the soil in the embankment flexible Mat 5 receives the preliminary stretching with providing fit flexible carpet 5 to the surface of the soil. In the above embodiment, the pipeline may use a shortened died is their carpets with accommodation ancarola elements in the embankment slopes. Created by stretching a flexible carpets extra effort pregrade pipeline ensures a stable position of the pipeline until the natural compaction of the embankment. To prevent exposure ancarola elements due to the potential for erosion and subsequent destruction of the layer to strengthen the use of geotextile grid 13 filled with soil. The geogrid is made of a textile material honeycomb with hexagonal cells, which are formed when sewing in a checkerboard pattern of parallel strips spaced paired seams.

During the construction of the pipeline on these earlier versions use the device for securing a pipeline containing imposed symmetrically on the pipeline section of flexible carpet, each parallel to the pipeline, the marginal portion of which is equipped with a bar and contains placed it parallel to the pipe anerousis longitudinal element. As ancarola elements are filled with soil cylindrical textile containers. In the marginal areas of the flexible Mat perpendicular to the eyelets are made of at least one slit on the depth of the lugs to facilitate the introduction of eyelets textile containers. Sections of the eyelets allow the introduction into each of them whic is in its line of textile containers with significant width of the flexible carpet.

As the flexible material of the carpet is technical fabric with a relative elongation at break 15-38%.

The container textile made in the form of filled with soft soil capacity, the length of which exceeds its diameter. The tank has a mechanical boot sleeve and secured to the shell tanks symmetrically to the longitudinal axis of the lifting loop. Shell capacity formed by the fastening of the transverse edges of the cloth of the connecting seam. The lower and upper ends formed from panels, fastened with its curved edges with a drum.

Thus, by pinching edge plots flexible carpet soil backfill provided the opportunity by pre-stretching flexible carpets create an extra effort pegregalejo pipeline, which is especially important in the conditions of irrigation pipeline during the first 3-5 years of operation of the pipeline, when the soil backfill is not bridge, harden, clog and ballasting ability is low.
