Description

FIG. 2

The invention relates to hydraulic melioration, mainly to drainage of land for use in agriculture.

The purpose of the invention is to increase efficiency by protecting the soil from wind erosion.

Figure 1 presents the scheme of the modular section of the drainage and humidification system; Fig. 2 is a diagram of the connection of the wells with each other and with the pumping station by siphon conduits; FIG. 3 is a schematic of an automatic groundwater level controller installed at a conduit; Fig, 4 is a diagram of the installation on the well of a wind pump sprayer.

The dehumidification system is from the drainage wells 1 (Fig. 1), which are connected via a siphon conduit 2 to the central well 3, and the latter in turn is connected with a siphon conduit 4, 5 and intermediate wells 6 to the pump station 7 Horizontal drains 8 are connected to the siphon conduit 2, which connects the peripheral wells 1 with the central 3, which are located in the zone of least sensitivity to fluctuations in groundwater levels during the period of drainage using vertical drainage. On the siphon conduit 4, which connects the central well 3 to the pump station 7, an automatic groundwater level regulator 9 (Figures 2 and 3) is installed, the Regulator 9 is located in the well 10 and contains a level sensor float 11 and a throttle valve 9, connected by a lever mechanism 12. The well 10 is communicated by a deaf pipe 13 to the absorber well 14 of the groundwater, performed at a point characteristic of the whole massif. In the drainage wells 1, wind pumps 15 are installed (FIGS. 4 and 5), containing an impeller 16 installed in the working chamber 17 and connected with the shaft 18 to the impeller 19.

In order to eliminate distortions, the impeller 19 has a support 20 at the top and is equipped with a stopper 21. The wells 1 are made with a bowl-shaped mesh tip 22, and the pumps 15 are equipped with a support 23 that tightly closes the well equipped with ejector holes 24. Water is pumped out of the pumping system station 25. Water enters the outrigger 26 from the modular sections of the drainage and humidification network and is discharged through the pressure pipeline 27 to the water intake. Siphon conduits 2, which connect wells 1 to central well 3, have a star connection

28, which in turn is connected by a larger diameter pipe to the central well 3.

Drainage system

works as follows

In spring, pump station 25 is turned on for the purpose of drainage, therefore in

The water tank is lowered to a certain level, and since the siphon water line 5 in the initial period is in the submerged state and when the pump 25 station 25 is operating between the levels in wells 1, 3, 6 and the anankamer 26, a drop is formed vacuum forces and head flow of water from wells 6 through siphon conduits 4 and 5 into the avant-chamber 26. It is assumed that siphon conduits 2, 4, 5 are constantly in a charged state. Groundwater levels decrease more rapidly closer to wells 1 and 3. A uniform decrease in the level of groundwater along the periphery is carried out by horizontal drainage, which connects directly to the siphon conduit 2. Water from the soil under the action of hydrostatic pressure and vacuum forces enters the drainage, further in

the siphon conduit 2, to the well 3 and to the pumping station 7. To prevent the vacuum from breaking in the siphon conduit, the automatic regulator 9 is adjusted to higher control levels, taking into account the required rate of implementation. The water from the absorber well 14 through the pipeline 13 enters the well 10, in which the float 11 is installed. If the water level becomes higher than the specified value, under

By the action of the buoyancy force, the float 11 floats up and drives the throttle regulator 9, which rotates in the siphon conduit 4 and passes water. If the water level in the soil is set to a predetermined value, then the float 1 keeps the controller closed and the water from the modular section is not pumped out by the pump station 7.

In the spring, the soil is subjected to rapid desiccation; water is pumped out of wells 1 by means of wind pumps 15 and is sprayed. In this case, the soil is protected from wind erosion, more intensive evaporation of water and drainage of the soil occur. Pumps 15 are driven by wind. The wind acts on the impeller 19, causes it to rotate, and since the impeller 19 is rigidly mounted on the shaft 18, it rotates

an impeller 16, which captures water from chamber 17 and feeds to screen head 22 through a pressure pipe. Water trickles, a pass screen head 22, hit the impeller 19 and sprayed around the field. During operation of the impeller 19, a vacuum zone is formed between the mesh tip 22 and the impeller 19, which facilitates the extraction of water from the well. In the case when it is not necessary to perform drainage and irrigation with the help of a stopper 21, the impeller 19 is turned off. In the case of irrigation, water from wells is taken only by a wind pump 15 and sprayed over a dried area.
