(54) DEVICE FOR YROKOLODKI KROTOVIN

The invention relates to drainage amelioration, namely, to devices of an installation of gaskets mezzanine. A mover is known that contains a knife-rack with deepened and non-buried parts in the ground, and a drainage device attached to the end of the deepened part with a combustion chamber, a nozzle for supplying fuel G1.

However, this mover has an insufficient temperature for securing the ground reliably: burning liquid fuel in air does not allow the temperature to be higher, which does not allow for complete sintering of the mole’s walls to form stronger walls.

Another device is known for laying i molehills, including a leg stand with a part that is buried and not buried in the ground, and a drainage unit with an injector, a combustion chamber and a nozzle attached to the bottom of the buried part, pipelines for supplying fuel, oxidizer, and body heat injection components f2.

The purpose of the invention is to increase the efficiency and reliability of fixing the walls of the crotodren, as well as to quantitatively regulate the supply of components to the crease chamber.

This goal is achieved by the fact that the device is equipped with a pipeline, a dem for supplying magnesium powder with a termite installed in a hollow leg loop and connected to the narrowing area of the injector.

In addition, from the other end of the pipe for supplying magnesium powder with a thermite, there is a sealed hopper with a source of compressed air and a window for loading components, and an air pressure regulator is installed on the air duct in a sealed hopper.

The mover contains a hollow knife-rack with a recessed 1 and a non-recessed 2 parts in the ground, mounted at the end of the recessed part of the draining unit 3, inside of which 25 is located on the combustion chamber 4, an injector 5 for fuel supply and an injector 6. The knife rack has in the ground part of the receiving holes 7 for air leaks through the cavity 8 of the knife-stand 30 into the combustion chamber 4, the fuel line 9 with the valve 10, the pipeline 11 for components with a nozzle 12, a hermetic hopper 13 with a cover 14, an air pipe 15 with a regulator 16 and skny 17 for loading additional tional high dopant, e.g. termite with magnesium powder. The composition of thermite powder is 50% of aluminum powder and 50% of iron dioxide powder, which is with magnesium powder; in the ratio of 50% of thermite and 50% of magnesium (on top).

The device works in the following way.

The knife rack is submerged to the required depth into the ground, fuel is fed through the fuel manifold 9 with the valve 10 open, to the nozzle 5. The nozzle is ignited and brought to a predetermined combustion mode, while the ejector is discharged through the holes 7 into the cavity of the knife-rack 8, air is drawn in, which is heated in the combustion chamber to 1300-1500 ° C.

Further, additional air is supplied to the heated air through the pipe 11 for the components into the combustion chamber 4 — a mixture of thermite powder and magnesium from the hopper 13. Using compressed air supplied by the air to the air duct 15. The air supply is regulated by the pressure regulator 6 in the heated air in the combustion chamber The mixture of termite with magnesium ignites and raises the temperature of hot gases to 2000-2500 ° C. The feed rate is adjusted depending on the soil properties and its filtration properties. The photocell moves in the required direction, and a drainage is formed behind it after burning liquid fuel to the sintering temperature of the product (1500-1800 ° C). .

Such an implementation of the crooker ensures an increase in temperature in the combustion chamber: 1300-1500С to 22002500 С, which contributes to the complete sintering and melting of the soil with the formation of more durable walls of woodJ.

Regulating the supply of thermite with magnesium to the combustion chamber, is achieved

creating a different degree of sintering of the soil, creating, depending on the technology requirements, sections of the wall of pipes with different water permeability or with continuous coatings that do not allow water to pass through and serve as conduits to the soil irrigators.

The application of the proposed device makes it possible to obtain an annual economic effect per one drainage drainage machine as compared to the construction technology of drainage from. ceramic pipes in the amount of 50006000 rubles, mainly due to the reduction of the material intensity of the process.
