Description

The invention relates to hydrotechnical reclamation, primarily to the drainage of land in agriculture.

A well-known moisturizing system includes drains, drainage collectors, aeration crosses, a closed transporting collector, an open drainage and dampening channel, wells, a water source-water receiver 1.

The disadvantage of this system is the manual control of water distribution.

A drainage-wetting system is also known, which includes a water intake source, water supply and drainage collectors and wells equipped with automatic level controllers 2.

A disadvantage of the known system is the need to manually maintain the water regime of the soil in a predetermined depth interval.

The purpose of the invention is to provide automatic maintenance of the soil water regime at a predetermined depth interval.

The goal is achieved by the fact that the drainage and humidifying system, which includes a water intake source, water supply and drainage collectors and wells, equipped with automatic level controls, is made with drainage collectors arranged in two rows parallel to the average floor surface marks at levels corresponding to the specified depth interval, and the inlet mouths at the head sections of the collectors and the outlet mouths at their ends are equipped in the intake wells with regulators respectively upper and a lower level control.

FIG. 1 shows a schematic plan of the system; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. one.

The system consists of a water intake source 1, closed collectors: water supply 2, waste 3, humidifying 4, desiccating 5 and drainage 6-drains 7; wells: water intake 8, intermediate 9, secret 10 and differential 11, -

automatic controls of the upper 12 and lower 13 levels.

Level controls are float type.

The system works as follows.

With excessive moisture, the groundwater level rises on the drained fields and, accordingly, in the water intake wells 8, at the end sections of the drainage collectors 6, where the float drives of the gates of the automatic regulators 13 of the lower level float. Excess drainage flow is discharged into drainage collectors 5, of which into discharge collectors 3, then into water intake 1. When groundwater levels draw down, the float drives of the gates of automatic regulators of 13 levels lower in the wells, stopping the drainage discharge.

With the intensive use of soil moisture, groundwater levels decrease on the floor and in the adjacent drainage and wetting collectors 6, 4 wells (intermediate 9 and secret 10), as well as in differential 11 and water intake 8, where the automatic regulators 12 levels are set to controlled humidification, the float drive of the regulator valves is lowered, opening the way for the water from the watering pipe 2 to the wetting collectors 4, of them to the drainage 6, then to the drains 7 with infiltration into the soil to replenish the groundwater . When the preset groundwater level is reached, the float drives of the gates of the automatic regulators of the 12 levels are set to the predetermined position, the water intake from the water supply pipe 2 and the water source 1 is stopped.

By the same principle, water distribution on the water supply network (water supply pipe 2, discharge and drainage collectors 3 and 5) is automated, where in water intake wells 8 automatic regulators of 12 and 13 levels are also installed in the appropriate position.
