iii The invention relates to irrigated agriculture, mainly within soil irrigation. A subsurface irrigation system is known that includes an irrigation pipeline with water outlets that supply water to humidifiers L. The disadvantage of this irrigation pipe is that it can only be used for irrigation. Other pipelines serve to transport water to other irrigation cards, flush the network and discharge the wash water from the system, which increases construction costs. Closest to the present invention is a irrigation device, including a pipeline with water outlets (sprinkling and for furrow irrigation), installed separately on the pipeline and separated from one another by a flexible partition 2. A disadvantage of this device is the need to lay parallel to the irrigation path next to it a conveying pipeline for transporting water to downstream irrigation sections or for draining wash water. The purpose of the invention is to reduce the material intensity and enhance the functionality of the irrigation pipe. The goal is achieved by the fact that the flexible partition is made of two tapes interconnected at its attachment to the wall of the pipeline. FIG. 1 is a schematic representation of a closed irrigation system, the plan in FIG. 2 shows the proposed irrigation device and nodes connecting its successive links with each other and with the power line; in FIGS. 3-8, the irrigation device with various system operation options, cross sections. Irrigation devices 4, made of links of pipes 5, perforated in a horizontal plane from two sides, are connected to supply line 1 - a higher-order distribution distribution pipeline. the inside of which is placed and fixed in a vertical plane along forming flexible seals 6, made of two tapes along the entire length of the pipes. Through the openings 7, the irrigation device 4 communicates with the tubular humidifiers 8. At the head and at the end of each link, controllable, for example, hydraulic pulses, switching levers 9 connecting the irrigation 10 and transporting the 11 paths of the head link with the power line 1 as well as a transporting path or a collecting-industrial path 12 of each previous link with a transporting path of the Subsequent one through a well 3, the transporting path of the previous link with a irrigation path of the next one. The proposed irrigation device works in the system of subsurface irrigation as follows. Before the start of irrigation, the levers 9 are moved to the position that closes the ends of the irrigation and collecting and washing paths of all the links of the irrigation device. If necessary, simultaneous irrigation of the first and second links of the irrigation device, counting from the supply line 1, with the shift levers 9 opens the entrance to the conveying cavity 11 of the first link and the irrigation paths 10 of the first and second links. At the same time, the water entering the irrigation cavity of the head section of the li-irrigation device 4 through the water outlet openings 7 of the pipeline 5 enters the irrigation device below the first irrigation device 8 and then enters the collecting and washing path 12 of the irrigation device 4 . The water entering the internal cavity of the flexible partition 6 of the head section of the irrigation device transits through the well 3 into the irrigation cavity of the second irrigation device, from which The trees connected to it enter the watering of the next section and into the collecting path of the second link of device 4 (Fig. 7 and 8). Upon completion of irrigation from the humidification network connected to the head and second links, the command is given to overlap 9 irrigation paths of the first and second links with the help of levers, and to switch on 9 irrigation paths of the third and fourth links to work with the appropriate levers. In this case, through the transporting path 11 of the first and second links of the device 4, water transits (Fig. 4) into the irrigation cavity of the third link of the device 4, and through the transport link of the third link into the irrigation path of the fourth link, through water outlets in them into the humidifier pipes and through them into the collecting and washing cavities of the respective devices 4, etc. Flushing the humidification network is usually done no more than once during the growing season and, as a rule, at the end of the season. Washing the irrigation network of two units of the device 4 can also be performed simultaneously. Usually the last vegetative irrigation is completed by washing. At the same time in the first link of the irrigation device 4 work irrigation and transporting paths

f

Phage 2 (Fig. 5), and in the second link irrigation tract (Fig. 6). The washing water from the humidifiers 8 enters the collecting and washing path 12 of the irrigation device (Fig. 8) and is withdrawn from the site. When comparing the cost indicators for the construction of the subsurface irrigation system including the proposed irrigation device, the following was taken into account. In a conventional subsurface irrigation system, they must be laid in one trench transporting irrigation and collecting-washing pipelines. When the proposed irrigation device is included in the system, it performs the functions of these three pipelines. Replacing two pipelines, for example, with a diameter of 150 mm by an elastic two-layer partition, saves costs of 508 rubles / ha.
