Abstract

The invention relates to hydraulic reclamation and can be used to regulate the water-air regime of soils. The purpose of the invention is to increase the efficiency and efficiency of managing the water-air regime of the soil. The system is equipped with a non-pressure conduit 7, and the regulating nodes 10, 11, 12 are made with a central 13 and peripheral wells 16, the central wells 13 at the collector conduits 3 communicating with the peripheral through nozzles equipped with downstream level regulators and connected to the peripheral wells of the regulating nodes 12 communicating with their central wells by nozzles with an upstream regulator, while the pressure pipeline 4 is equipped with a pair of ejector-siphon devices that communicate it with the central well and regulate its node 12 and coupled via an ejector latch and a pressureless water conduit 7. In the operation of the horizon level control groundwater define the upstream regulators. When there is an excess of moisture, the water enters the peripheral wells 16 along the drains. When intensive drainage is necessary, the discharge conduit enters the operation mode not dehumidification. When water is supplied to the system, it is supplied by gravity and using a pumping station. Water under pressure passes through siphon-ejector devices, ensuring the pumping of water from wells 13. 1 cp f-ly, 6 ill.

The invention relates to hydrotechnical reclamation and can be used to regulate the water-air regime of soil.

The aim of the invention is to increase the cost-effectiveness and efficiency of managing the water-air regime of the soil.

0 5 - d 5 by a conduit 4. Peripheral wells 16 knots 11 (FIG. 3) are equipped with level 19 regulators of the upper pool, connected to gates 15 of a rigid thrust 18, and their central wells 13 communicate with wells of 16 regulating nodes 12 (FIG. 4), the central wells 13 of which are in communication with the pressureless conduit 7. The wells 16 of the nodes 12 are equipped with a headwater regulator 20 connected to the gate 15. The wells of the nodes 13 12 are connected to the pressureless conduit 7 and through the dual ejector siphon devices 21 and 22 with pressure conduit .4.

In an ejector-siphon device 21 and 22 (Fig. 5), a throttle valve 23 is installed, which is actuated by a lever gear 24 connected to an articulated elastic membrane 25. Thus, the discharge conduit 4 communicates along the water intake route through the well without pressure. 13 of the assembly 12 and the ejector-siphon devices 21 and 22, as well as through the valve 26 and the ejector device 27. In addition, the pressure conduit 4 is connected to the pressure line 28 through the valve 29. Valves 30-32 are installed on the pressure line 28, which serve to control the operation mode trunk and pressureless pipes 4 and 7. Pressurized line 28 communicates with the water source 6 and forebays pumping station 9 /

The dehumidification system in the dehumidification mode works in the following way.

With the help of regulators 19 upstream, set the required horizon

regulation of groundwater levels depending on the crops sown. During the period of excess moisture, water from the soil enters drains 1, then into the collector 2 of the second order, then into the collector 3 of the first order and deck 16 of the node 11, When the water level in the well 16 rises the value of & h occurs, the opening of the shutter 15. Water through the nozzle 14 enters the well 13, follows through the conduit 7 to the well 16 of the node 12 (Fig. 4), where excess water is discharged into the well 13 and enters the free-flow conduit 7.

In the dewatering mode, in the control wells of the 16 knots of the 11 sectional structure, the following cases of their work may occur: in one of the wells 16, the water level is higher than normal per well-ground ih, and in the other lower by feh Water entering the well 13 rises by the value of LH and between water levels in the left well 16 and well 13 appear to be a z-drop, which causes the opening of the left gate 15. An internal overflow occurs. flow reduction

In cases where a lead is required., Intensive drainage, the pressure conduit 4 is turned on in the drain operation mode. The valve 5 on the pressure conduit 4 is closed, and the valve 8 on

conduit 7 is open. - Water, passage

through the main conduit 7, flows through the ejector 27, creating. Discharge in the pressure conduit 4. The water level in the well 13 of the unit 12 acts on the throttle valve 23 which under the action of discharge

opens, water enters. from the well 13 into the pressure conduit 4 and the outflow pumping station 9. With the increase in flow, the right ejector-siphon device 22 automatically switches off under the action of hydraulic flow forces, and

in the left device 21, the shutter opens even more, since the flow contributes to a greater deflection of the membrane 25. As the flow decreases, shut off the valve 8 and discharge water through the conduit 7.

In the case when it is necessary to supply water for pre-soil moistening to the required area, water from the water source 6 is supplied to

the conduits 4 and 7 by gravity and using the pumping station. In the first case, water from the water source 6 is supplied to the pressure conduit 4 with the valve 5 open and supplied to the wells 16 nodes 10, then to the collectors 3 and 2 and drains 1.

In the second case, the water enters, in the outflow pump station 9 with open valves 30-32, valves 5 and 8 are closed. Water is taken from the advance chamber, fed into the discharge conduit 4 and further to the wells of the 16 nodes 10, from which it is taken to irrigated areas. The water under pressure passes through the ejector-siphon devices 21 and 22, at the same time the left device closes and the right device opens.
