Description

The invention relates to agriculture, in particular to the reclamation of over-wetted lands, and may be used for two-way control of the water regime of drained lands.

The purpose of the invention is to improve the efficiency of the system.

Figure 1 shows the system plan; figure 2 - section aa in figure 1; FIG. 3 is a diagram of a water control well in a pressure mode; figure 4 - the same, in the free mode; figure 5 - scheme gidroavtomat.

The system contains the main channel 1, completed along section 2,

collectors of channel K-I, K-2, K-3, i flowing into the main channel 1 between the modular sections 2.

The collector channels and the main channel 1 are equipped with level 3 water controllers designed to regulate the volume of accumulated water coming from modular areas during the spring and storm periods.

The module sections 2 are equipped with humidifier drains 4, flowing into the collectors 5, interconnected at the bottom of the section 2 with respect to the direction of flow, bypass collectors 6, laid under the lower sections and brought into the collecting channels located behind them. The inputs of the collectors 5 and; The overflow collectors 6 located in the collecting channels are equipped with water controllers 7.

To release air from the system, it is equipped with 4 air tubes 8 connecting KOHUfei drains, laid parallel to the collectors 5, brought into collecting channels and equipped with check valves 9 at the outlet. To maintain the optimum groundwater level in the modular sections 2 collectors 5 length provided with water controllers 10, placed in wells 11.

To ensure that the water regulator 10 is put into operation, a valve 12 is installed on the collector 5, a branch pipe with a valve 13 is connected to the well I1 from the collector 5, and the water regulator 10 communicates with the collector 5 through a pipe with a valve 14. The controller 10 includes located in the well 11 the float 15 kinematically connected

with valve 16, blocking the nozzle with the valve 14.

The system works as follows.

In the spring and rain periods, the system works on draining. At the start of operation, the system closes. In this way, the level controllers 3 close, on the collecting channels, the water coming from the modular sections fills the collecting channels, overflow collectors 6, collectors 5 modular sections, humidifiers drain 4. Air through the air tube 8 and check valve 9 being pushed out of the system. After that, the water regulators 3 are opened, and the water from the system rushes along the main channel 1. At the same time, the water regulators 7 on the bypass manifolds 6 and the rear 12 in the well 11 are open, and the water regulators 7 in the heads of the collectors 5 of the modular sections and valves 13 and 14 in well II, closed. The check valve 9 on the air tube 8 also closes.

The bypass collectors 6, the collection Torah 5 and the drain-humidifiers 4 operate in a vacuum mode, providing intensive water decrease. The significant difference in the horizons between the humidifier drains 4 and the end of the overflow manifold 6 allows the vacuum to remain sufficiently high in the humidifier drains 4 and at the same time accumulate water in the collector channels.

In the dry season, water regulators 7 are opened in the head of the collectors 5, valves 12 are closed and valves I3 and 14 are opened in wells 1I, water regulators 7 are closed at the outlet of the bypass collectors 6. Water from the discharge channels enters the collectors 5 and in the drains-humidifiers 4 o Water regulators 10 maintain a given level of groundwater.
