(54) МЕЛИОРАТИВ-НАЯ СИСТЕМА(54) MELIORATIVE SYSTEM

Изобретение относитс к сельскому хоз йству , в частности, к мелиорации земель.The invention relates to agriculture, in particular, to land reclamation.

Известна мелиоративна система, включающа насосную установку и закрытую осушительно-увлажнительную сеть в виде двух русов дрен с вертикальными отводами 1.The land-reclamation system is well-known, including a pumping unit and a closed drainage and humidification network in the form of two drains with vertical outlets 1.

Недостатком этой системы вл етс ее сложность и трудоемкость исполнени .The disadvantage of this system is its complexity and complexity of execution.

Известна и друга мелиоративна система, состо ща из насосной установки и закрытой осушительно-увлажнительной сети, выполненной в виде трубчатого дренажа 2.Another reclamation system is known, consisting of a pumping unit and a closed drainage and humidification network, made in the form of a tubular drainage 2.

Недостатком этой мелиоративной системы вл етс необходимость прл увлажнении почвы подачи больщих объемов оро сительной воды.The disadvantage of this ameliorative system is the need to wet the soil by supplying large amounts of irrigation water.

Цель изобретени - экономи оросительной воды путем использовани грунтовых вод, поступающих в закрытую осушительно-увлажнительную сеть.The purpose of the invention is to save irrigation water by using groundwater flowing into a closed drainage and humidification network.

Это достигаетс тем, что осушительно-оросительна сеть расположена ниже уровн грунтовых вод и разделена на обособленные зоны, соединенные .между собой насосной установкой.This is achieved by the fact that the drainage-irrigation network is located below the level of the groundwater and is divided into separate zones connected between each other by a pump installation.

На чертеже изображена мелиоративна система, разрез.The drawing shows a reclamation system, a section.

Мелиоративна система состоит из насосной установки 1 и закрытой осушительно-увлажнительной сети в виде закольцованного горизонтального коллектора 2, к которому подсоединены дрены 3. Задвижка 4, установле 1на на коллекторе 2 и расположенна в колодце 5. раздел ет закрытую осушительно-увлажнительную сеть на обособленные зоны. Зон может быть две и более в зависимости от рельефа местности.The ameliorative system consists of a pumping unit 1 and a closed drainage and humidifying network in the form of a looped horizontal collector 2, to which drainage 3 is connected. The valve 4 is installed 1a on the collector 2 and is located in the well 5. divides the closed drainage network into separate zones . Zones may be two or more, depending on the terrain.

На коллежторе 2 по обе стороны от задвижки 4 установлены трубопроводы 6 и 7, которые при помощи задвижек 8 подключены к насоснойOn the collegiate 2 on both sides of the valve 4 installed pipelines 6 and 7, which by means of valves 8 are connected to the pump

Claims

Installation 1. To improve the water-air regime of the root layer, an aeration installation consisting of a pressure tank 9 and a compressor 10 can be connected to the pump 1. It saturates it with air before being supplied to the dehumidification network. The end of the collector 2 of each zone comes out in the form of a knee And with a latch 12 into the manhole 13, communicated by means of the outlet 14 with an open channel m 15, the bottom of which is located above the closed all-wet humidification network. This creates the condition for reducing the closed drainage and humidification network below the groundwater level. The system works s.peduyush.im way. When the need arises to moisten the root layer, the drainage system by valve 4 is divided into two autonomous zones, closing the valves.-12. A pump installation 1 is connected to one of the zones using valves 8, for example the right zone, using pipeline 6 as a suction line. The left part of the system is connected by means of the pipeline 7 and the valves 8 to the pressure tank of the aeration unit 9. Pump installation 1 supplies water, and compressor 10 pumps air into a pressure tank 9. Air, due to high pressure, dissolves rapidly in water and aerates it. Under the action of air pressure, accumulating in the upper part of the pressure tank 9, the aerated water enters through the nozzle 7 into the second zone of the system, and then is filtered through the regulating drains 3 into the soil. After raising the water level in the root zone of the soil in the adjacent zone of the system and moistening, the pumping I and aeration plants are switched to opposite pipelines b and 7. Gravity water is sucked out of the flooded root zone and fed to the zone that was previously drained her levels in the root zone. After raising the water level to the desired height, switch the pump unit 1 to reverse operation. Alternating operation of the water intake and supply system provides the moistening of the root zone, and water is used for drying from the dry area. During high-water periods, the system.ma works in the implementation mode. When the groundwater level in the soil rises above the edge of knee II, the water flows into the well 13 and through the water outlet 14 into the open channel 15. The reclamation system saves irrigation water, since water is used directly from the drainable area to moisten the soil. The invention of the reclamation system, which includes a pumping unit and a closed dehumidifying and humidifying network, is characterized in that, in order to save irrigation water, the dehumidifying and humidifying network is located below the groundwater level and is divided into separate zones, interconnected by a pumping unit.
