Abstract

The invention relates to land reclamation and can be used for draining wetlands and overmoistened mineral lands with well permeable subsoil. The aim of the invention is to increase the drainage effect of the system and automate its operation. The dehumidifying and humidifying system consists of a vertical well 1, the mouth of which through the diaphragm 5 with an opening is connected to the drainage pipe 6. On the air duct 2, put inside the well below the water level, an air distributor is installed using two pipes 18, 19 that have diaphragm 20 , 21 with a hole. The diaphragms 20, 21 are fitted with valves 22 and 27, which are rigidly connected with the floats 26, 28 placed in the float chamber 15. The float chamber 15 is in communication with the earth pit 17. The valve 22 is located above the diaphragm 20 and the valve 27 is below the diaphragm aI 21. As the groundwater level rises above a predetermined limit, the compressed air from the air duct 2 enters the well 1, and from there to the reservoir 7, the water freed from the air through the pipeline 8 moves into the open channels. Well 1 works like an airlift and the groundwater level drops. When the groundwater level drops below the limit, the holes in the diaphragms 5 and 20 overlap, the air supply stops and the groundwater level stops. 3 hp f-ly, 3 ill. i (L

Description

one

The invention relates to land improvement and can be used for draining wetlands and overmoistened mineral lands with well permeable subsoil.

The purpose of the invention is to increase the drainage effect of the system and automate its operation.

FIG. 1 shows the plan of the site; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows the node I in FIG. 2

The dehumidification system includes a well 1, connected by air ducts 2 and 3 to a source 4 of compressed air. Wellhead 1 through diaphragm 5 with plug hole 13

flow into the well 1, the overpressure on the valve 22 decreases, and as the float continues to rise, the valve 22 opens the fully opening of the diaphragm 20. In parallel, the float 14 is raised, causing first the opening of the opening 11 in the valve 10, and then the opening of the opening in the diaphragm 5 As a result, the compressed air from the air ducts 2 and 3 begins to flow through the pipe 18 into the cavity of the well 1. The air-water mixture that forms at the same time from the well 1 goes through the drainage pipe 6 to the air release tank 7, from where it is released The water from the air through pipe 8 moves to open channels 9.

It is not connected to the drainage pipe 6, which is connected to the reservoir 7 for discharge. 20 The well works like air holes, to which the elevator is connected, and the groundwater level of the drainage pipe 8, which flows into the channel 9. The opening of the diaphragm 5 overlaps a valve 10 with a hole 11, which is overlapped on top by another valve 12 with a travel stop 13, rigidly connected to a float 14 placed in the float

zhatsya. When the groundwater level drops below the upper limit, valves 10, 12, 22 and 24 overlap from

25 versts in diaphragms 5 and 20, respectively, the flow of air into the well ceases, and the decrease in the groundwater level stops as the ground level decreases.

a chamber 15 connected by a pipe 16 with a ground well 17. On the air duct 2 introduced below the water level in well 1, an air distributor is installed of two pipes 18 and 19, having 15 and 21 772 diaphragms

flow into the well 1, the overpressure on the valve 22 decreases and as the float continues to rise, the valve 22 opens the orifice plate 20 completely. At the same time, the float 14 is raised, causing the opening of the opening 11 in the valve 10 and then opening of the opening in the diaphragm 5. As a result , compressed air from air ducts 2 and 3 begins to flow through pipe 18 into the cavity of well 1. The air-water mixture that forms at the same time from well 1 goes through the drainage pipe 6 to the air release tank 7, from where it is released air from the air through pipeline 8 moves into open channels 9.

20 The well at the same time works as an ern elevator, and the groundwater level is low;

zhatsya. When the groundwater level drops below the upper limit, valves 10, 12, 22, and 24 close the orifices in diaphragms 5 and 20, respectively, air flow into the well stops, and the groundwater levels stop to stop. With a decrease in groundwater levels

Water below the lower limit, the float 28 and valve 27 are lowered, and the opening in the diaphragm 21 opens. The holes in the diaphragms 5 and 20 remain blocked. As a result, szha

version respectively. The diaphragm 20 35 air through the pipe 19 and the air duct 2 enters the well 1, from there into the soil, causing an increase

the wire 2 enters the borehole 1, and from there into the ground, causing a hole with a hole, overlaps the top with valve 22 with a hole 23 that is blocked by another valve 24 with stroke limiter 25 rigidly connected to the float 26. The diaphragm 21 is blocked from below by valve 27, rigidly associated with the float 28. The floats 26 and 28 are placed in the water intake chamber 15. The groundwater level is indicated by the line 29.45 by the valve 27, the diaphragm 20 of the groundwater level, which must be blocked by the valves 22 and 24, to maintain the system is set by the installation floats 14, 26 and 28, with the aim of increasing stability
