According to the main author. St. No. 374063 is a well-known irrigation system with dead-end irrigators, made with a reverse slope of the bottom to the local distributor that feeds water, and on the local distributor, retaining structures with an overflow shield are arranged below the outlet of the sub-command irrigators to ensure that the irrigation water levels necessary for irrigation and dumping its surplus due to overflow through the shield to the downstream areas. With the open culvert of the supporting structure, the water levels in the district distributor fall to household water, which should be below the bottom of the command irrigators, and all the water from the irrigators flows back to the district distributor 1.. However, the presence of an open distribution channel implies the use of a well-known irrigation system under certain topographic conditions and limits the use of irrigation possibilities for wide-area frontal sprinkling machines due to the impossibility of moving its wings through a distributor. The purpose of the invention is to expand the operational capabilities of the irrigation system by using it to power wide-range frontal sprinklers. The goal is achieved by the fact that the irrigation system is equipped with distribution wells located on precinct distributors at the places where the sprinklers connect to them, and district distributors are closed, with overflow boards installed in the shaft wells and forming two chambers in them, to which respectively from the top and the downstream is connected to the distributor, and the camera on the side of the upstream is in communication with the irrigator. FIG. 1 shows a plan of the proposed irrigation system; in fig. 2 - section of manhole wells along the distributor; in fig. 3 - longitudinal profile over irrigation. m with a cross section of the mine well. The irrigation system consists of supply channels 1 (main, economic) with hydraulic engineering and road structures on them, a closed local distributor 2, which is laid on the slope of the area, and open dead-end sprinklers 3 with horizontal reverse slope of the bottom. Open irrigators are arranged in plan, as a rule, parallel to each other to obtain irrigated plots with borders of 4 rectangular shapes and necessary sizes, depending on sprinkling technology or irrigation technology, as well as on natural conditions and cultivated crops. Water from the district distributor 2 is supplied to the sprinklers 3 through the dwelling wells 5, which have an inlet 6 for receiving water from the upper reach of the distributor and an outlet 7 for transferring water to the downstream of the distributor. For receiving - supplying water to the command sprinklers, the dingy wells have holes 8, made to the size of the mouth of the sprinklers. A shaft well with a shield 9 is divided into two chambers — a working 10 and a transit one. The shield has an overflow ridge 12 at the mark of a normal retaining level of water 13 in the command irrigation command. In this case, the shield 9 is made so that the intake openings in the sprinkler 8 are in the working chamber 10. In the shield 9 at the bottom of the well there is an opening 14 blocked by a flap 15. With the G5 closed and the distributor, the water level in the well 10 rises and the filling of the sub-command sprinklers begins. The water level in them rises gradually, horizontally, and when the ridge 12 of the shield reaches the mark, the sprinklers fill up completely and the water begins to overflow into the transit chamber 11 and then into the downstream distributor. When water is taken from the sprinklers, compensation expenses are automatically transferred from the distributor through the working chamber to the sprinklers, and the normal retaining level of water 13 is maintained in the sprinklers. If there are irrigated plots on the distributor below, the necessary water flow for them is automatically passed through the ridge of the overflow shield 9. Then the forced retaining level of the water is set in the sub-commands of this well. The necessary transit costs for the below irrigated areas can also be passed through the opening 14 in the shield 9 by maneuvering the damper 15. After the irrigation is finished, the damper 15 opens and the water level in the working chamber of the well decreases to household water that should be below the bottom of the command irrigators. In this case, the water level in the irrigators also decreases at the same time, and all the remaining water from them goes back to the shaft well and to the distributor. The advantages of the proposed irrigation system are to engage in agricultural use with irrigation of a territory with hilly terrain with relatively large slopes; in expanding the area of application of the sprinkling machines and increasing their seasonal time use factor; in simplifying the irrigation network, since it eliminates waste channels, which increases the land use ratio; in increasing water use by eliminating discharges

water from sprinklers in any irrigation schemes; in the automation of water distribution between irrigators without automation devices; in uninterrupted water intake by a sprinkler over the entire length of the irrigator; in significant simplification, reduction and cheapening of exploitation. In addition, the cost of building the proposed system does not exceed the cost of building traditional systems for similar irrigation equipment.
