Abstract

FIELD: water supply.

SUBSTANCE: method consists of laying a pipeline from a building that is used in the cold season to the place where water is distributed. The pipeline is laid at depth, or with an insulating coating on the surface of the ground, or with an insulating coating in the air, with the condition that the angle of inclination of the pipeline must be at least 3°. At the point of water distribution, a hole is placed with a depth below the freezing depth of the soil in the given area. At the bottom of the hole there is a sealed container with two holes on top, the end of the pipeline coming from the building is connected to one hole, and another pipeline comes out of the second hole, the horizontal part of which has a positive or negative angle of inclination, and a water dispensing tap is placed at its end. The lower end of the pipeline is located at a distance of at least 1/4 of its internal diameter from the bottom of the sealed container, where the volume of the sealed container is at least 1/3 of the volume of the vertical part of the pipeline. Insulation material is placed in the hole with pipelines and a sealed container. Water is supplied from the building to the pipeline through a tap. A second pipeline is also connected to the pipeline in the building, into which compressed air is supplied through a tap.

EFFECT: method of water supply is simplified, operation reliability is increased, and ease of use is ensured.

Description

The invention relates to water supply devices for non-residential premises or areas at any time of the year, including at sub-zero ambient temperatures, from a house or premises equipped with a central water supply.

Typically, in such cases, a pipeline is laid in a trench at a depth below the depth of soil freezing in a given area and the section of the pipeline emerging from the trench to the surface is thermally insulated, which, accordingly, requires large capital costs for the arrangement of a water supply system (Code of Rules 31.13330.2012 Water supply. External networks and structures (Clause 11.40).

The disadvantage of this solution is that if the pipeline is not operated constantly, but periodically, this can lead to freezing of water in the section of the pipeline emerging from the trench to the surface, despite the presence of thermal insulation.

The technical result is to simplify the method and design of the water supply system for non-residential premises or areas of the area, increase the reliability of its operation at any time of the year, ease of operation, as well as reduce the costs of the water supply system due to the absence of the need to lay a pipeline in a trench at a depth below the freezing depth of the soil .

The technical result is achieved by the fact that a water supply method consisting of laying a pipeline from a building that is used in the cold season to the place where water is distributed, characterized in that the pipeline is laid at depth, or with an insulating coating on the surface of the ground, or with an insulating coating in the air, with the condition that the angle of inclination of the pipeline must be at least 3°, in the place of water distribution there is a hole with a depth below the freezing depth of the soil in the given area, at the bottom of which there is a sealed container with two holes on top, to one hole connect the end of the pipeline coming from the building, and another pipeline comes out of the second hole, the horizontal part of which has a positive or negative angle of inclination, at its end a water distribution tap is placed, while the lower end of the pipeline is located at a distance of at least 1/4 of its internal diameter from the bottom of a sealed container, where the volume of the sealed container is at least 1/3 of the volume of the vertical part of the pipeline, insulation material is placed in the hole with pipelines and the sealed container, water is supplied from the building to the pipeline through a tap, a second pipeline is also connected to the pipeline in the building, in which supplies compressed air through a tap

The drawing shows a method of water supply and a system for its implementation.

The water supply method contains a building 1 or another structure that can be used in the cold season, a pipeline 2 coming out of it, which is laid in the ground 3 at a depth with the condition that the angle of inclination 4 of the pipeline 2 must be at least 3°. In the place where water is distributed, a hole 5 is drilled in the ground 3 to a depth below the freezing depth of the soil 6 in the given area. At the bottom of hole 5 there is a sealed container 7 in which there are two holes 8 and 9 on top. The end of pipeline 2 is connected to the first hole 8, and pipeline 10 comes out of the second hole 9, the lower end of which 11 is located at a distance of at least 1/4 of the internal diameter pipeline 10 from the bottom 12 of a sealed container 7, and at the upper end of the pipeline 10 there is a tap 13 through which water is distributed 14. Hole 5 is filled with insulating material 15. Water 16 is supplied from building 1 to pipeline 2 through tap 17. To pipeline 2 in building 1, a pipeline 18 is connected, into which compressed air 20 is supplied through a tap 19.

The water supply method works as follows. Water 16 from building 1 or another structure that can be used in the cold season, with tap 17 open, is supplied to pipeline 2, which is laid in the ground 3 at a depth with the condition that the angle of inclination of pipeline 4 must be at least 3°. In the place where water is distributed, a depression is made in the ground 3, for example, a hole 5 is drilled to a depth below the freezing depth of the soil 6 in the given area. At the bottom of hole 5 there is a sealed container 7 which has two holes on top. Through the first hole 8, the pipeline 2 fills the sealed container 7 with water, which leaves the sealed container 7 through the lower end 11 of the pipeline 10 through the second hole 9 and at the upper end of the pipeline 10, water 14 is distributed through the tap 13. To prevent the water from freezing in the container 7, hole 5 is filled with insulating material 15.

When the water intake through tap 13 is stopped for a long period, so that the water does not freeze in the pipeline, tap 17 is closed and tap 13 is opened. Then, compressed air 20 is supplied to pipeline 2 through pipeline 18 with tap 19 open, which, thanks to the angle of inclination 4 of pipeline 2 of at least 3°, displaces water from pipeline 2 and the sealed container 7, which flows from the pipeline at the water distribution point 14. When When the water level in the sealed container 7 reaches the level of the lower end 11 of the pipeline 10, water from the pipeline 10 in the form of an emulsion will be removed by airlift (air lift) [1]. Since all the water from pipeline 10 is not removed, after the supply of compressed air 20 is stopped, the remaining water from pipeline 10 flows into a sealed container 7, which is located at a depth below the freezing depth of soil 6 in a given area and, accordingly, does not freeze in it. The volume of the sealed container must be at least 1/3 of the volume of the vertical part of the pipeline 10, and the horizontal part of the pipeline must have a positive or negative angle of inclination, which will allow the remaining water in this part of the pipeline, after stopping the supply of compressed air 20, to either drain into the vertical part of the pipeline 10, or drain out through tap 13 14.

Pipeline 2 can be laid not only in the ground 3 at depth, but also on the surface of the earth or in the air (in the latter two cases, the pipeline must have an insulating coating) with the condition that in all cases the angle of inclination 4 of pipeline 2 must be at least 3°, in this case, horizontal sections (with zero or opposite slope) are excluded.

Compared with the known solution, the claimed invention makes it possible to simplify the method and design of the water supply system for non-residential premises or areas of the area, increase the reliability of its operation at any time of the year, ease of use, and also reduce the cost of the water supply system due to the absence of the need to lay a pipeline in a trench on depth below the freezing depth of the soil.
