The device in the first embodiment (Fig. 2)

consists of a base machine 5, on which is located the feed mechanism of the braid in the form of a replaceable coil 6 with a braid 1 wound on it in the form of a sleeve, which is passed through a rack 7 and channel 8 in the working organ draining 9. On the base machine 5 there is also a radio receiver 10 electrically connected to the propulsion unit of the base machine 5. The radio receiver 10 receives electromagnetic signals from the radio transmitter 11 electrically connected to an electromanometer 12, which is installed in a sealed chamber 13. The interchangeable coil 14 is also mounted in the chamber 13 and is wound oh thereon inflatable inner protective sheath 3, the end 15 of which is turned inside out and fixed to the inner wall of the guide tube 16. The end of the braid 17 1 is connected to the outer surface of the guide tube 16.

The system 18 supplying adhesive composition (binder) is connected to the cavity of the pipe 16,

located before the end of the 15 inflatable shell 3. System 19 supply worker

agent is connected to the sealed chamber 13. The electromanometer 12 is electrically connected to the working agent supply system 19. Rack 7 is fastened with a lever 20 to the base machine 5.

In the device according to the second embodiment (Fig. 3), a woven shell (braid) manufacturing mechanism 21 is installed on the base machine 5, for example, a circular base machine, which is rotatably mounted on the drum 22. In the woven shell 1 manufacturing mechanism 21 on bearings installed pipe 23, which is associated with the delivery system 18, communicates it.

The device works in the following way.

The base machine 5 begins to move, while the drains 9 forms a well in the ground. The woven sheath 1 (braid) begins to unwind from the interchangeable coil 6 and is laid in the formed, well. At this time, the binder supply system 18 is turned on and the required amount is pumped into the woven sheath 1. After that include the system 19 filing working agent. The inner inflatable protective sheath 3 begins to move inside the woven sheath 1, pressing it against the ground, while it moves in front of itself a binder that permeates the woven sheath 1 and is partially pressed into the ground by pressure. In this case, the binder presses on the draener 9, increasing its longitudinal force. In the case of breaking through the inflatable casing 3, the working agent leaves the inflatable casing 3 through the well into the vertical slot in the ground and the hole 8. The pressure in the housing 13 drops and the electromanometer 12 sends a signal to the radio transmitter 11, which sends a signal to the receiver 10. The radio receiver 10 sends a signal to the propeller of the base machine 5, which stops. After the elimination of the breakthrough, the manufacturing process of the pipeline begins again.

The manufacturing mechanism 21 executes a sheath of fiber that goes into the opening 8 in the draining unit 9. When the woven sheath 1 is removed from the mechanism 21, an adhesive (binder) enters it from the pipe 23 from the system 18.

When the terrain changes, the mechanism 21 for manufacturing the sheath 1 rotates in the drum 22. Otherwise, the device works in the same way as in the first embodiment.

Example. A pipeline with a diameter of 70 mm and a length of 100 m is manufactured. With the help of a tractor, the Kirovets make a puncture in the ground with a diameter of 75 mm. During the formation of a puncture, a fire hose (braid) of 1-75 mm is placed into the hole, unwinding it from the drum mounted on the tractor. After that, from the free end of the fire hose (braid) 140 kg of glue “Sprut. Then

Fixed at the end of the free fire hose polymeric sleeve D-72 mm from PVC film. The film sleeve is turned inside out and compressed air is fed into the bent edges 5 of the sleeve under a pressure of 0.1 MPa. After laying the polymer hose, the pipeline is sealed and maintained at a pressure of 0.1 MPa for 36 hours, during which the sprout will polymerize the joint, connecting the hose to each other.

 The device according to the third variant (Fig. 4) consists of a base machine 5, on which a piercing 9 with a stand 7 is installed (working member), in which a channel 8 is made, communicated with the binder supply system 18

composition

The working body 9 is connected to the expander 24, in the groove 25 of the cylindrical part 26 of which two torus elastic chambers 27 and 28 are installed, connected through the hydraulic distributor 29 to the hydraulic system 30.

On the end part of the expander 24 a braid feeding mechanism 6 is arranged, made in the form of a shaft 31 with rolls 32 and 33 of belts 34 and 35 mounted on it. The ends of which are fixed on the guide

 pipe 16.

. The pipe 16 communicates with a sealed chamber 13, in which a replaceable coil 14 is placed with an inner protective sheath 3 wound on it, the end 5 of which is turned inside out and fixed on the inner surface of the pipe 16.

The working agent supply system 19 communicates with the hermetic chamber 13.

The device according to the third variant operates as follows.

 The base machine 5 is moved, which moves the puncture 9 in the ground with a longitudinal knife.

Liquid is pumped into the torus chambers 27 and 28 sequentially. Torus chambers 27 and 28, expanding, increase

bore diameter. The soil, when the hole is enlarged, closes the longitudinal slit arising from the movement of the longitudinal knife. Through channel 8, glue (or cement) is continuously pumped into the cavity of the well. The tapes, sliding from the rolls 32 and 33, are laid against the walls of the hole in the ground. The number of tapes can be any. Coiling in rolls can be right or left, or mixed.

System 19 in the elastic sleeve 3 sweat

Compressed air, which begins to move along mites 34 and 35, presses them against the walls of the hole in the ground. The gaps between the belts 34 and 3.5 are filled with glue.

After the glue has polymerized, a strong pipeline is entrained.

Example. A hole in the ground is used to make a hole with a diameter of 100 mm, which is expanded to a diameter of 200 mm by

inflating elastic chambers by pumping oil under pressure of 12 MPa.

Three helical layers of metal tape 0.3 mm thick are laid on the wall of the hole in a checkerboard pattern. The space between the layers of tapes is filled with the adhesive “Sprut. Layer thickness is 0.5 mm.

Thereafter, an elastic sleeve made of 1 mm thick polyethylene film is inserted into the ribbon sheath. In the pipeline create air pressure of 1.2 MPa. The pipeline is kept under pressure for 20 hours before the adhesive is polymerized.

The device according to the fourth variant (Fig. 5) consists of a base machine 5, on which the working body (rotor) 9 and conveyor 36 are installed.

The base machine 1 is followed by a vibratory roller 37.

One end of the additional outer protective inflatable casing 38 is wound on a drum 39 and fixed on the guide tube 16. A sealed chamber 13 with a coil 14 on which is wound an inner protective sheath 3 connected to the tube 16. The end of the inner protective sheath 3 is turned inside out and fixed in the pipe 16.

In the cavity of the outer protective sheath 38, rolls 32 and 33 are installed with ribbons 34 and 35, the ends of which are fixed on guide tube 16. Rolls 32 and 33 are fixed on shaft 31 of piston 40.

The sealed chamber 13 is in communication with the working agent supply system 19.

In the cavity of the sheath 1, formed by ribbons 34 and 35, between the gun 40 and the inner shell 3, glue is pumped.

A device for carrying out the proposed method works as follows.

The rotor 9 of the base machine 5 is dug a trench into which an additional external protective inflatable casing 38 is laid.

System 19 in the pipe 16 is pumped working agent.

The piston 40, together with the rolls 32 and 33 and glue, begin to move along the shell 38 under the action of the inflation of the inner shell 3.

The tapes 34 and 35 are moistened with glue and laid down with screw rows in the sheath 38. The inner surface of the tapes 34 and 35 is covered with a protective sheath 3. After

polymerization glue gets a solid pipeline.

As the base machine 5 advances, the soil developed by the rotor 9 is conveyed to conveyor 36 into the trench and compacted by vibrating roller 37.

Example. The rotor is made a trench 2 m deep and 500 mm wide. A semi-cylindrical seal with a diameter of 500 mm is made at the bottom of the trench. The trench is laid shell 38 with a diameter of 500 mm

, made of PVC film with a thickness of 1 mm and inflated with compressed air under a pressure of 0.03 MPa. The trench is covered with soil and the soil is compacted. After that, the pressure in the shell 38 is increased to 0.1 MPa.

In shell 38, four are laid.

0 screw rows of steel strip 34 and 35 with a thickness of 0.1 mm and a width of 400 mm. The direction of the screw piling in the rows alternate (right, left). The gaps between the ribbons 34 and 35 and the shell 38 are filled with Sprut glue by moving the glue tube through the arm.

An inner protective sheath 3 with a diameter of 494 mm of a 1 mm thick PVC film is placed on the surface of the tapes.

Inside the formed pipe create a pressure of compressed air, equal to 0.6 MPa. The pipeline is kept under pressure for 24 hours before the glue is polymerized. After that, the pipeline is operated.

The use of the invention allows to automatically lay the pipeline in the ground, while the outer and inner surfaces of the pipeline are insulated.

The combination of the inflatable shell around which the woven fabric is placed, impregnated with the binder composition, increases the strength of the pipeline and prevents the formation of an avalanche-like destruction, because the woven fabric suppresses the pressure energy of the pipeline, as it consists of interlacing threads, therefore the propagation of longitudinal destruction in such a pipeline is impossible.
