Description

; о со оо со | The invention relates to agricultural land reclamation and can be used in the cultivation of various crops of irrigated agriculture, mainly as a combined irrigation and drainage system of rice farming. The famous rice irrigation system, which includes a pumping station, irrigation and drainage channels, devices for supplying water to checks and discharge, in which irrigation and discharge channels are closed and placed in one trench, with the discharge pipeline connected by means of an overflow valve to the irrigation pipeline and in the upper the parts are equipped with drainage holes I. The rice irrigation system is also known, comprising a pumping station, a distribution pipeline, a waste collector, irrigation, drainage and waste piping with water outlets and discharges and a settling basin 2. A disadvantage of the known irrigation systems is that the discharge of water by a gravity flow method takes considerable time to complete complete drainage of large areas, for example, before rice is harvested. At the outflow of water under pressure through the drainage holes located in the upper part of the waste pipeline, the filter layer and the soil are washed out, and then the soil subsides and the irrigation pipeline in the trench is above the waste. The outflow of water under pressure through the drainage holes also leads to flooding and waterlogging of the territory adjacent to the discharge pipeline. In addition, the following irrigation systems are characterized by the following: failure to use waste and drainage water to re-irrigate the crop, such as rice, in order to save irrigation water; the impossibility of ensuring in a short time a forced supply of irrigation water, for example, during the period of initial flooding of rice due to insufficient capacity of the irrigation pipeline; lack of interchangeability of irrigation and waste pipelines; high construction cost of irrigation and waste pipelines, as well as devices installed on them for supplying water to the check and discharge; the difficulty of repairing the waste pipeline due to its location in the trench under the irrigation pipeline. The purpose of the invention is to reduce capital and operating costs and improve the environmental situation of the irrigation source and water intake. The goal is achieved by the fact that in a rice irrigation system containing a pumping station, closed distribution pipelines and waste collectors, irrigation, waste and drainage pipelines with water discharge and waste disposal facilities and a settling basin, suction and pressure lines of the pumping station are connected by means of additional pipelines and by-pass valves with a waste collector, distribution pipe and a settling basin, irrigation pipelines are combined with drainage and discharge pipes they are supplied with drainage water receiving devices, and the outflow structures are combined with wastewater and equipped with receiving devices for receiving contamination. In addition, the settling pool is equipped with a by-pass valve and a bottom outlet.

Irrigation system works as follows.

1. The initial flooding of rice, i.e. the forced supply of irrigation water through the waste collector.

In the pumping station 5 (Fig. 1 and 2), for example, 3 pumping units 4 (I, I and III) were installed. With the simultaneous supply of irrigation water to two pumping units, the passage of their flow is ensured by the pressure (distribution) pipeline 6, and with the forced water supply by the three pumping units, the flow collector 12, which has a large diameter, passes the flow. Irrigation water from avancamera 3 (Fig. 1 and 2) along the main suction line 25 with 27 open and 28 closed valves using pumping units (I, P and III) along the main pressure line 26 with 29 open and 30 closed valves is fed into the waste the collector 12 with the open valve 24 and the closed valves 17, 21 and 31 in the discharge pipe 6 and the discharge collector 12. Through the discharge collector 12 (Fig. 1), the irrigation water is transported to the distribution wells 7 (Fig. 1, 4 and 5). The pressure (distribution) pipe 6 and the waste collector 12 are arranged in a stepwise manner, with the pressure pipe 6 having an excess over the waste collector 12, sufficient to allow irrigation, waste and drain pipelines 8 to pass to the left and adjacent the waste collector 12 ( Fig. 5).

In the distribution wells 7 (Figs. 1, 4 and 5), the irrigation water from the waste collector 12 enters the combined map irrigation, waste and drainage pipelines 8 with devices for receiving drainage water with 33 open and 35 closed valves.

When water is supplied to the combined irrigation kart irrigation and drainage pipelines 8 (Fig. 1, 6, 7 and 8) and when the pressure (P) in the pipelines exceeds one diameter, ball type drain valves 45 (Fig. 9 and 14) the lower valve receptacle 44 is lifted, the squeezing springs 49 (Fig. 10) are compressed and take up space in the upper sockets 43 of the valves 45 (Fig. 45 (Fig. 9 and 14)), closing the openings for receiving drainage water (Fig. 14).

Through combined kart irrigation, waste and drainage pipelines 8 (Fig. 1, 16 and 17), irrigation water flows into the combined water outlet, waste and inspection structures 9 (Fig. 1) with trash grids, garbage disposal chambers and garbage disposal baskets 68 (Fig. 16 and 17).

Combined water outlet, waste and inspection structures 9 (Fig. 1) are installed on combined map irrigation waste and drainage pipelines in places where water is supplied to checks and discharges, i.e., in the sections of kart irrigation discharges (hollows) 11 (Fig. 1 and sixteen).

The operation of the combined water outlet, discharge and inspection facilities 9 (Figs. 1 and 16) during the supply of irrigation water is as follows.

Water under pressure (P) (Figs. 20, 18, and 16) flows from the combined map pipeline 8 to one hundred to 51 combined water discharge, discharge and viewing structures 9 (Figs. 1 and 16) where, having closed the clap 70 (firm. 19 and 20), mounted on the partition 59, which divides the station into two parts, enters the water distribution chamber 60 (Figures 18, 20 and 19). Then through the water distribution chamber 60 and the additional drain 62 (Fig. 18, 20 and 19), through the openings of the lower trash rack 61, branch 63 for supplying irrigation water, opening the clapping (check valve) 64 on branch 63, as well as through the upper branch 65 and the holes in the upper trash rack 66, the irrigation water enters the water-dispensing chamber 67 (Fig. 18, .20 and 19), while washing the openings of the trash grids 61 and 66 (Fig. 18, 20 and 19). From the water disposal chamber 67, water enters the water outlet and waste pipelines 53 with the valves 52 open in the wells 55 (Fig. 18 and 16) and through pipelines 53, extinguishing energy to the quencher hot sinks 58, goes to the sprinklers (hollows) 11 rice karty- checks 10 (Fig. 16 and 1), filled with irrigation water (Fig. 1, right) forced flooding). Each rice crop map can be flooded with forced flow from two combined, waste and viewing structures 9 (Fig. 1, right, forced flooding) located on opposite sides of rice cards 10 (Fig. 1), and forced water discharge can be realized in the same way. .

II. In the event of a breakdown of the pressure (distribution) pipeline, i.e., while ensuring the supply of irrigation water to crop rotation plots along the discharge collector, the operation of the irrigation system is carried out similarly to the 1st water distribution scheme.

III. Accelerated discharge of waste water into the pool-sump simultaneously through the discharge manifold and pressure (distribution) pipeline using pumping units of the irrigation pumping station (forced discharge).

From each rice card 10, water can be discharged through two outlets, discharges and observation structures 9 and 18 located on opposite sides of the rice cards (Fig. 1, right-side forced reset). During the accelerated (forced) discharge of water from the rice cards 10 and sprinklers-discharges 11 (Fig. 16 and 17) enters the wells-absorbers-sumps 58 combined water outlet, waste and viewing structures 9 (Fig. 1) with trash grids and garbage receptacles baskets. Through the water discharge and waste pipelines 53 with open valves 52 in the wells 55 (Fig. 16), waste water under pressure created by the difference in water levels enters the water distribution chambers 67 of the sewers 51 of the combined structures (Fig. 18 and 21).

FIG. 18 depicts one hundred K, and FIG. 21 working the combined wastewater, waste and viewing facilities during water discharge from the rice cards. With the flapper 64 closed at the outlet 63 for supplying irrigation water, a portion of the water from the waste-dispensing chamber 67 enters the receptacle basket 68 with openings, which is installed in the waste water chamber 69 (Figs. 18, 19 and 20). Between the walls of the garbage disposal basket 68 and the waste water chamber 69 and. There is a gap (figs. 18, 19 and 21) necessary for the passage of water coming out of the openings of the garbage receptacle 68. Large fraction waste that comes with waste water to the basket 68 , it settles in it, and the water along with. fine debris through the holes in the basket enters the waste water chamber 69 and, opening the cracker (check valve) 70 of the waste water chamber, enters the combined irrigation map drainage and drainage pipelines 8 (Fig. 18 and 21). The flapper (check valve 70 (Fig. 18 and 21) is designed to prevent debris from washing out of the basket 68 during the supply of irrigation water in the stand 51 (Fig. 16, 18 and 21) of the combined outflow, discharge and inspection structures.

Part of the waste water along with small debris from the water-dispensing chamber 67 (Fig. 18 and 21) through the openings of the lower trash rack 61, located at 45 ° angles to the waste water chamber 69 with the basket 68 and the outlet of the discharge and waste pipelines 53 (Fig. 18 and 21) enters the water distribution chamber 60 and from there into the combined irrigation, waste and drainage pipeline 8 (Fig. 18 and 31). Heavy waste of large fractions, falling on the lower trash rack 61, located at a sharp angle to the garbage disposal basket 68, rolls down into the basket, settling in it (Figures 18 and 21). As the basket 68 is filled with debris and clogged with the holes of the basket and the trash rack 61 (Figs. 18 and 21), the carrying capacity of the combined discharge, discharge and viewing structure is reduced. The waste water completely fills the waste water dispensing chamber 67 and together with light fine debris through the openings of the upper grate-holding grate 66 (Fig. 18, 21) at an angle to the upper partition 72 of the chamber for light debris 73, and the opening of the discharge and waste pipelines 53 (FIG. 18 and 21) enters the upper outlet 65, from which, via the additional water distribution stand 62, it enters the water distribution chamber, and then into the combined pipeline 8 (Fig. 18 and 21), Light debris from large fractions in the water The distribution chamber 67, when it is completely filled with water over the wall of the upper trash rack 66 (Figures 18 and 21), located at an acute angle to the upper partition 72, rises up and takes place in the upper chamber for light debris 73. As the water discharge stops light debris settles in the dust collector basket 68 (Fig. 18 and 21).

The outlet 63 (figs. 18 and 20) with a clapper (non-return valve) 64 is designed to increase the capacity and pressure of the combined water outlet, discharge and viewing structure during the supply of irrigation water, as during its passage through the openings of the trash grids 61 and 66 reduction of pressure and irrigation water consumption in discharge and waste pipelines 53.

The irrigation water discharged under pressure from the irrigation water outlet 63 pushes the light debris of large fractions located in the water-dispensing chamber 67 away from the outflow and waste pipelines 53, thus preventing their possible clogging.

In the flapper (non-return valve) 64, holes are made similar to the holes of the garbage receptacle 68, so waste water is discharged through the outlet 63 (Fig. 18).

After filling, the garbage receptacle 68 is taken out through the hatch 71 (Figs. 18 and 21), freed from the debris and set back.

Stokes 51 (Figs. 16 and 18) of combined water outlet waste and viewing structures 9 (Fig. 1) are also used as viewing wells for identifying, for example, sections of possible breakdowns of the combined map irrigation, waste and drainage pipelines 8

(Fig. 16 and 18), for which it is necessary to open the hatch 71 (Fig. 18), remove the trash racks 61 and 66 and inspect the combined pipeline 8 through the opening of the water distribution chamber 60.

From the combined irrigation, waste and viewing structures 9 (Fig. 16) with trash racks, garbage disposal cages and waste receiving baskets, the waste water flows into the combined irrigation card waste and drainage pipelines 8 (Fig. 16, 17 and 21) receiving drainage water. If the pressure of the waste water in the combined pipelines 8 is larger than their diameter, for example, during the forced discharge of water from the rice system, then under the action of pressure (P) ball drainage valves 45 of devices for receiving drainage water from the lower valve nest 44 rise up, squeezing springs 49 (FIG. 18) and occupy places in the upper sockets of the valves 43, closing the openings for receiving drainage water (FIGS. 9 and 14). Discharge water through a combination of card irrigation, waste and drainage pipelines 8 (Fig. I, 6, 7 and 8), which had 12 in the direction of the discharge collector and 12 pressure (distribution) pipeline 6, with open bypass valves 33 ( Fig. 4, 5) connecting the combined kart irrigation, waste and drainage pipelines 8 with the waste collector 12, enters the latter, filling it. If the discharge water pressure (pressure P) is larger than the diameter of the discharge manifold 12, then with the valves 34 open at the outlet 35, the waste water fills the discharge (distribution) pipeline 6 (Fig. 4 and 5).

The waste manifold 12 and the pressure (distribution) pipe 6 are laid in a trench with a slope towards the pool-sump 14 and the pump station 5. The waste water through the waste collector 12 and the pressure (distribution) pipe 6 is diverted to their end and initial parts, respectively Then, from the pressure pipeline 6 with the open valve 17 (Fig. 2) connecting the pressure pipe 6 to the waste manifold 12, it is transferred to the latter, which has an increased diameter from this part, sufficient to receive the waste water flow from the pressure (distribution) pipeline 6 (Fig. 2). At the same time, the valve 31 on the pressure (distribution) pipe 6 and the valve 24, which connects the pressure pipe 6 to the waste collector, must be closed. The increased in diameter end portion of the waste manifold 12, with the valve 21 closed (FIG. 2) connecting the collector to the settling basin 14, the waste water enters an additional waste collector 15 (FIGS. 2 and 3) having a diameter similar to the end portion of the waste collector 12, i.e., which is a branch of the latter to the suction line of pumping units of the irrigation pumping station 5 (Figures 1, 2 and 3). The units 4 of the pumping station 5 have an additional suction line 32 (Fig. 2 and 3) from the additional waste manifold 15, and the openings of the suction lines are located in the additional manifold 15 of the stepped one, for example for the pump unit I (Fig. 2 and 3) above the axis of the additional collector 15, II - axis, and III - below the axis (Fig. 3) and equipped with level sensors, which give signals for automatic shutdown of pumps, when the water levels in the additional collector 15 fall below the permissible for each of the additional suction boiling lines (Figs. 2 and 3), in order to prevent breakage of pump units. The additional discharge manifold discharges water under pressure due to the difference of water marks in the check and the end part of the collector through an additional suction line 32 with open 28 and closed 27 valves in the main suction line, through pipelines to pump units 4 (I, II, III) , with the help of which water is accelerated simultaneously through the discharge manifold 12 and the pressure (distribution) pipeline 6 (Fig. 3, 2 and 1); With the help of pumping units (I, I, III) the waste water along the main pressure line and closed valves 29 and open relief valves 30 on an additional pressure line enters an additional pressure pipe 16 (Fig. 2, 3 and I), a settling basin 14. IV. Accelerated discharge of waste water into the settling basin at the same time through the discharge manifold and pressure (distribution) pipeline by gravity flow method. The operation of the irrigation system is similar to the water distribution scheme described in III, except for the operation of pumping units 4 (I, P, III). Then, with closed valves 28 on additional suction pipes and open bypass valve 21, waste water through discharge manifold 12 (Fig. 2, 3), extinguishing energy in well 13 enters the settling basin 14. V. Irrigation system operation during discharge of waste water in the pressure (distribution) pipeline by gravity method or with the help of a pump unit in case of a waste collector breakdown, similar to that described in 111 water distribution scheme, however, the valves 33 in distribution wells 7 (Fig. 4, 5 and 1) are closed. In this case, it is also possible to accelerate the discharge of waste-water, for example, using a single pump unit, atm 4 (Fig. 2), if the pipeline 6 provides the inflow of waste water necessary for the operation of the pump unit. Vi. Accelerated discharge of waste and drainage water through the waste manifold using pumping units and feeding it through a pressure (distribution) pipeline back to irrigation, such as rice, using the same pumping units. Consider the plan of the universal irrigation system (Fig. 1), namely the location in terms of rice cards 10, combined kart irrigation, waste and drainage pipelines 8 and mounted on them combined discharge, waste and viewing devices 9 and 18, and distribution wells 7. Suppose that the first and third combined kart irrigation, waste and drainage pipelines 8 adjacent to the left and right of the waste collector 12 and the pressure (distribution) pipeline 6 in the first and third distribution x wells 7 (FIG. 2, work for supplying irrigation water to rice cards 10, and the second and fourth combined map pipelines 8 adjacent to the waste collector and the pressure (distribution) pipeline in the second and fourth distribution wells on the left and right, discharging waste and drainage water (Fig. 7 shows the work of the combined kart irrigation, waste and drainage pipelines and the combined water discharge, discharge and viewing facilities adjacent to the waste collection on their left yelling head Nome pipeline). Then, from rice cards 10 (Fig. 1, left), for example, to be emptied, waste water through combined water discharge, waste and viewing structures 9 with gate valves 52 opened in them (Fig. 16) goes to the second and fourth left and right kart irrigation, waste and drainage pipelines 8, working on the discharge of water from the system (in Fig. 1, the left part of the system). Through the combined pipelines 8, the waste water is discharged to the waste collector 12 (Fig. 1), and if the pressure (P) in the pipelines 8 is smaller than one of their diameter, then in this case the ball drainage valves 45 of the devices for receiving drainage water (Fig. 9 ) installed on the combined map pipelines 8 (Figs. 6, 7 and 8) are located in the lower slots 44 of the valves 45, the drainage water through the holes in the upper slots 43 of the valves 45 also enters the combined map irrigation, drainage and drainage pipelines 8 ( Fig. 15). Then, with open bypass 33 and closed 34 valves in the second and fourth distribution wells 7 (Fig. 1, 4 and 5), the waste and drainage water from the second and fourth left and right of the combined map irrigation, waste and drainage pipelines begins to flow into the waste collector 12, which is diverted to the water intake. With the closed valves 17, 24 tt 21 (Fig. 2 and 1), the waste and drainage water is supplied through an additional waste collector 15 to the additional suction line 32 of pumping units 4 (Fig. 2 and 1). Acceleration of the discharge of drainage and drainage water through the discharge manifold 12 and its simultaneous supply to re-irrigation of rice in the pressure (distribution) pipeline 6 is carried out, for example: measures, two pump units II and III (Fig. 2 and 1). Then, with the pump unit 1 closed on the additional suction pipe (Fig. 2 and 3) and the open valves 28 on the additional suction pipes of the pump units II, III (Fig. 3 and 2) closed valves 27 on the main suction line 25, waste and drainage water the action of the pressure caused by the difference of water marks, or by means of a vacuum system installed on the pumps, flows through the main suction line 25 to the pumping units II, III of the pumping station 4 (Fig. 2 and 3), with which they are pumped out. Along the main pressure line 26, with the valves 29 of the pump units II, III open and the valves 30 closed, the wastewater and drainage water is supplied to the additional pressure line through the pressure (distribution) pipeline 6 with the valve 31 open on it (Fig. 2 and 1), transported to the combined kart irrigation, waste and drainage pipelines 8 and with open valves 34 on the taps 35 and closed 33 in the first and third distribution wells 7 (Fig. 1, 4 and 5) enters the first and third left and right of the pressure (distribution) pipe rovoda discharge collector 6 and 12 combined Cartesian irrigation, relief and drain pipes 8 (FIG. 1, which illustrates the operation of the left part of the irrigation system). Through combined irrigation kart, waste and drainage pipelines 8, irrigation water under the pressure (pressure P) closes the valves of the drainage water receiving devices (Fig. 14), fills the outlets 51 of the combined outflow, waste and inspection structures 18 and 9 (Fig. 16 and 20). With the open bypass valves 52 in the pads 55, irrigation water through the discharge and waste pipelines 53, wells (extinguishers, settling tanks) 58 irrigators, discharges (hollows) 11 fills 1, the left part is rice theme cards). To evenly drain the drainage water from the entire area of the irrigation system, it is necessary to combine the supply and discharge of water through the combined map irrigation, waste and drainage pipelines 8 (Fig. 1). That is, if the irrigation water is supplied through the first and third combined map irrigation, waste and drainage pipelines 8 adjacent to the left and right of the pressure (distribution) pipeline 12, then in the second case it is advisable to discharge the drainage and drainage water through them . VII. Simultaneous supply of irrigation and accelerated removal of waste and drainage water, proportional mixing of irrigation water from the discharge inside the discharge (distribution) pipeline and supply of mixed water for irrigation, such as rice. Irrigation water is supplied by pumping unit III (Fig. 2), while waste and drainage water is drained from the rice system by pumping unit II (Fig. 2). With the open valve 27 on the main suction line 25 of the pumping unit III (Fig. 2) and the closed valve 28 to the additional irrigation water through the main suction line 25 goes to the pumping unit 111 (Fig. 2), through which the main pressure line 26 at Open 29 and 30 closed valves on the main and additional pressure lines are supplied to the pressure (distribution) pipeline 6 with the valve 31 open on it (Fig. 2). Dump and drainage water is discharged from the rice cards through the waste manifold 12, with the valves 17, 24 and 21 closed, it goes to the additional waste collector 15 (Fig. 2 and 3) and with the open valve 28 on the additional suction line of the pump unit II (Fig. 2 , 3) and closed 27 on the main suction line 25 is supplied to the pump unit II, through which it is pumped out even at open 29 on the main and closed 30 valves on the additional pressure line, it is also supplied to the pressure (distribution) pipe 6, displacing water irrigation oh, and transported to rice cards 1-1 (Figs. 2, 1). VIII. Simultaneous accelerated diversion of waste and drainage water into the settling basin, irrigation supply, drainage and drainage water supply and supply for proportional displacement from irrigation and mixed water supply for irrigation of the cultivated crop, such as rice. In addition to the water distribution described in scheme VII, for example, 1 pump unit is used to speed up the discharge of waste water (Fig. 2). Then, with the open valve 28 on the additional suction pipe 32 (Fig. 3, 2) and the closed valve 27 on the main pressure line 25 of the pump unit 1 (Fig. 2 and 3), the waste and drain water is pumped out by the pump unit 1 and Pressure line 26 with closed 29 and open 30 valves on the main and additional pressure lines is fed into an additional pressure pipe 16, i through which, having extinguished the energy in the well-extinguisher 13, enters the pool-sump 14 (Fig. 2 and 1). To displace wastewater from irrigation in other, more complex proportions, water meters (not shown) are installed on the main pressure line 26 behind the valves 29, then the flow of the waste and drainage water is adjusted with valves 20 and 30 on the primary and secondary valves. pressure lines j, i.e. linchs, for example, part of the waste water is bypassed through valves 30 and is led through an additional pressure pipe 16 to the settling basin 14 (Fig. 2). Ix. Simultaneous supply of irrigation water 2 through the pressure (distribution) pipeline to irrigation and accelerated from waste water and drainage water through the waste collector to the pool-sump. For example, two pumping units II and III (Fig. 2) operate to supply irrigation water through a pressure (distribution) pipeline 6 (Fig. 2), and one pumping unit I (Fig. 2) pumps out waste and drainage water to pool sump. Then, with the opening of the EH valves 27 on the main and closed 28 - on the additional suction lines with the help of pump units II, III (Fig. 2) with the open valves 29 on the main and closed 30 - on the additional pressure lines II, III irrigation water along the pressure (distribution) pipeline 6 with the open valve 31, it is transported to irrigate the cultivated crop, such as rice (Fig. 2 and 1) At the same time, with the closed 27 and open 28 valves, on the main and additional suction lines of the pump unit 1 (Fig. 2, 3 ) reset and the water from the additional discharge manifold 15 flows to the pump unit 1 (FIG. 2), through which it is pumped out along the main pressure line with the valves 29 closed and 30 open, flows through the additional pressure line to the additional pressure pipe 16, which is transported in pool-sump 14 (Fig. 2). X. Pumping waste and drainage water from the settling basin and supplying it for re-irrigation of the crop, such as rice. If the settling basin 14 (Fig. 2 and I) is filled with waste and drainage water, then with open valve 21 connecting the discharge collector 12 to the settling basin, the water under pressure caused by the difference in water levels in the settling basin and the discharge collector fills additional waste collector 15 (figs. 2 and 3) and a certain part of waste collector 12. Then, for example, using two or one pumping units, it is possible to pump water from the sump basin similarly to the described water distribution schemes, which are accelerated. th discharge waste water on the discharge collector using pump units 4 (Fig. 2), the pumping station 5. XI. Supply irrigation water from the irrigation source to the settling basin, for example, to dislodge with waste and drainage water treated with herbicides and other chemical chemicals to reduce its toxicity and possible subsequent use for re-irrigation of rice, or bypass to irrigation source 1 through the bypass the valve 22 and the bottom outlet 23 connecting the settling basin 14 to the irrigation source (Fig. 1). For example, pump units I, III (Fig. 2) provide irrigation water to the settling pool 14. Then, with 27 valves open and 27 closed on the main 25 and additional suction lines of pump units I and III, the water goes to the pump units and with closed valves 29 on the main and., .. „,„ „covered 30 - on additional pressure lines, it is fed to an additional pressure pipe 16 (Fig. 2 and 1), through which, having quenched the energy in the well of the extinguisher 13, enters the pool - settling tank 14, moving with waste and drainage water In the whole year, during the irrigation and non-irrigation periods, i.e., in all cases when the pressure in the combined offset irrigation kart irrigation and drainage pipelines 8 (Fig. 1 and 15) is less than one of their diameter, the drainage water is received and discharged i.e. the system works like a drain. The use of the invention in amelioration will provide: savings in irrigation water, as for re-irrigation of rice, waste and drainage water or mixed in certain proportions with irrigation water is used, reduction of capital costs for construction of wastewater, drainage pipelines and devices for water supply and discharge, as well how they are made combined; reduction of operating costs associated with repairs and maintenance of irrigation, waste, drainage

pipelines and devices for supplying water to checks and its discharge, as they are combined, and devices for supplying and discharge of water prevent various debris from entering the pipelines; Improving the ecological situation of the source of irrigation and water intake, since the waste and drainage water contaminated with herbicides can, mine the water intake, be fed back through the pipelines for re-irrigation, for example, of rice or shifted from the irrigation inside the pipelines, reducing its toxicity to normal, and giving for irrigation or produce sludge in a sediment basin.

The expected annual economic effect from the use of this invention is 1,801 million rubles.
