The invention relates to hydraulic reclamation and can be used as irrigation and drainage of agricultural land.

A well-known regulator of the groundwater level, containing mounted on the tip drains are placed in the well of a stop valve with float actuator, it is provided with a tubular filter and located in the well chamber, the actuator of the locking device in the form of two pivotally connected with independently moving floats, one of which is placed in the chamber communicating through the tubular filter with groundwater above the regulator (inventor's certificate SU # 763519, CL E02B 11/00, 1980).

However, in the known controller the presence of the gauge tubular filter can lead to zakrivayu and exclude the ingress of water through it inside the tube and can't work on length regulation of drainage water depending on fluctuations in water level in the drainage system. Besides, at a certain point the location of the float occurs discharge of water from the system regardless of the hydrological regime of irrigated area, which leads to increased inflow of saline drainage water in water sources and purevsuren root-inhabited layer of soil, and the relatively low efficiency of cleaning of drains from the sediment. In addition, the movable cylinder with tarelka�first shutter, interconnected to move relative to each other in welded housing complex in operation and leads to significant efforts to overcome the hydrostatic pressure in the weld body, acting on the entire area of the gate when it is opened. These efforts reduce the reliability of operation of the device, and hence the reliability of its operation. On vertical rod due to friction of the rack there is no possibility to control the system to complete the trim lever of the device in two opposite directions, which leads to the randomness of the selection of its provisions.

Closest to the invention is a drain system, including drains, sewer, sealed holding tank with an air trap located at the mouth of drains (inventor's certificate SU # 1523632, CL E02B 11/00, 1989).

The disadvantage of this system is the discharge of water from the system regardless of the hydrological regime of the territory drained that leads to increased inflow of saline drainage water in water sources and purevsuren root-inhabited soil layer. In addition, it cannot provide for the needs of plants in water and air at different periods of the growing season.

The objective of this solution is the reduction of the risk of pollution of natural waters � saving water resources, as well as creating optimal moisture regime, and soil aeration.

The technical result is achieved in that the drain system, including drains and collector, at the mouth of which is in the drain well is a holding tank, holding tank associated with the outlet manifold via a well, equipped with a device for discharge of water, made in the form of a siphon, the descending branch of which is derived at the level of the tip of the discharge manifold, wherein the elbow of the siphon set at the level corresponding to the placement of the float of the float actuator with valve, and the float is placed at the corresponding critical watertable depth for the soil-climatic and hydrological conditions of the area in which is located the bilge system in the wall of the vessel has a hole connected by a conduit with drainage inlets drives.

In addition, the inlets drives are connected with the holes of sectional areas of the inlet manifold in the locations of drains, with the installation of filter inlets drives use the backfilling of waterproof material, in particular sand, gravel, slag, or synthetic wastes light industry.

The proposed drainage system is aimed at eliminating specified�'s shortcomings due to the design of the location of the float of the float actuator with valve, accordingly, the location of the bend of the siphon at the appropriate critical position of the groundwater level, which allows you to maintain the level of groundwater, to ensure the alarm system only when exceeding the critical level of ground waters on the territory drained and drain it of excess moisture, causing waterlogging and salinization, which can significantly reduce the discharges, and hence the salinity of drainage water in water sources and reduce the risk of contamination.

The system allows you to fully automate the process of maintaining groundwater levels at the level corresponding to the critical, ensures the supply of a quantity of water from groundwater in the root layer of soil, which increases the reserve of moisture for crop and provides an opportunity to reduce irrigation rates, which saves water resources. In addition, to provide the necessary moisture regime, and soil aeration resulting from the creation of optimal groundwater level in different phases of plant growth, reduce operational costs by eliminating manual labor on drained areas.

Comparative analysis of proposed technical solutions and prototype shows that the inventive combination of features part of essential features is� new, therefore, the claimed solution meets the criterion of "novelty."

The drawing shows a drainage system, a section along the axis of the collector.

The drainage system includes drains 1, inlet manifold 2 and exhaust manifold 3, between which is placed away from the tank 4 with siphon 5, descending branch 6 which is derived in the drain well 7 to the level of the outlet manifold 3. The float 8 with a horizontal plate 9, which is suspended on a flexible restraint 10 deadlift float actuator-valve 11, located, respectively, at the knee of the siphon 5. In the wall 12 of the container 4 made hole 13 to the intake pipe 14 through which it is connected with filter inlets drives 15, which is filtered ground water from the holes 16 between the sections of the inlet manifold 2 during the withdrawal of groundwater through the layer of waterproof material 17, in particular sand, gravel, slag, or synthetic wastes light industry. The bottom of the tank 4 and the bottom of the well 7 is formed in a rounded shape.

The drainage system works as follows.

When the groundwater level is above normal, the water coming from the soil into the drains 1, moves to the collector 2 and further through the holes in the collector sections 2 comes to the filter inlets drives 15, and profiltrovavshih through a layer of waterproof�x materials 17 (for example, sand) in the last downstream reservoir 2, the water enters the conduit 14 and then through the hole 13 into the container 4.

With increasing content of water in the tank 4 to the estimated location of the float 7, which is installed at elevation, respectively, of the tribe of the siphon 5, the valve 11 is lifted and letting all the water flow from the inlet manifold 2 into the container 4. The water level in it increases, reaching critical for the operation of the siphon 5 full section on the discharge of water from the tank 4 into the well 7. As a result, in the presence of the rounded bottom in the well 7, the discharge of water along with suspended sediments will be continually flush the sediment into the reservoir 3, which ensures the reliability of the system. After you reset the water in the tank 4 is sinking float down 8 to its initial position. As a result of reducing the level in the tank 4 of the float 8 and the plate 9, the valve 11 will be closed and the intake manifold 2. Thus, when the critical groundwater depth is defined as the position at which there is salinization of soils in the unsaturated zone and ensured the flow of some quantity of groundwater in the root zone (see Kharchenko S. I. Hydrology of irrigated lands, L. G., 1975, p. 169: Maslov B. S., Minaev I. V., Huber K. V. Handbook of reclamation. M. Rosa�repromised, 1989, p. 14).

Drainage system allows you to fully automate the process of drainage water for operation of drainage systems and reduce the flow of saline drainage water in the water sources that will improve the environmental situation, and to use some portion of the groundwater to increase water supply in agricultural crops, giving a somewhat reduce the consumption of irrigation water, i.e. to provide the necessary moisture regime, and soil aeration by creating optimal periods in different stage of plant growth, reduce operational costs by eliminating manual labor in the conduct of drainage water and save irrigation water and allow to maintain the correct balance of moisture in the soil. In addition, it allows purification from suspended sediments draining the well, which increases the reliability of its work in mutual communication with the siphon, as at the end of the descending branch of the 6 measured flow stream erodes the sediment in the presence of the rounded bottom to the outlet side of the manifold 3. Thus, construction of drainage and drainage systems according to the invention allows to achieve the desired technical result due to mutual fluid communication of the tank with a siphon, float float p�of ivoda with valve, and the holes in the container wall, respectively, connected to the pipeline, which is associated with filter inlets drives, when the permeability of backfill sufficiently ensured.
