Description

Изобретение относится к сельскому хозяйству, а именно к мелиорации.The invention relates to agriculture, namely to land reclamation.

Известна водозаборная дрена осушительно-увлажнительной мелиоратив- J ной системы, использующей грунтовые воды для увлажнения осушаемой территории, выполненная из гончарных трубок .с фильтрующим материалом по периметру и водонепроницаемым экраном Г1].A well-known drainage drainage of drainage and humidification reclamation system J using groundwater to moisten the drainage area is made of pottery pipes. With filter material around the perimeter and a waterproof screen G1].

Известна также дрена, включающая дренажные трубки и сплошную фильтрующую обкладку [21.Also known is drain, including drainage tubes and a continuous filter lining [21.

Недостаток указанных дрен — неравномерный забор воды в дрену по 15 ее длине.The disadvantage of these drains is the uneven intake of water into the drains along its 15 length.

Цель изобретения — обеспечение равномерного притока воды в дрену · по ее длине, при заборе воды из нее насосом или сифоном. 20The purpose of the invention is the provision of a uniform inflow of water into the drain · along its length, when taking water from it with a pump or siphon. 20

Указанная цель достигается тем, что дрена снабжена установленными на ней поверх фильтрующей обкладки в местах стыков трубок водонепроницаемыми кольцами, выполненными переменной · по длине дрены ширины.This goal is achieved by the fact that the drain is equipped with waterproof rings mounted on it over the filter plate at the joints of the tubes, made variable · along the length of the drain width.

На чертеже изображена конструкция водозаборной дрены.The drawing shows the design of the water intake drainage.

Водозаборная дрена включает дренажные трубки 1, фильтрующую обклад- 30 ку 2 стыка, водонепроницаемое кольцо 3, щели 4 мевду трубками.The water intake drainage includes drainage tubes 1, a filter lining - 30 ku 2 joints, a waterproof ring 3, and slots 4 between the tubes.

Водозаборная дрена работает следующим образом. ·Water intake works as follows. ·

Водозаборный насос или сифон, подключенный к устью дрены, создает внутри нее давление меньше атмосферного. Под действием перепада давлений над дреной и внутри нее возникает ток воды по фильтрующей обкладке 2, находящейся между·внешней стенкой дренажной трубки 1 и водонепроницаемым кольцом 3, далее она поступает через щель 4 в полость дрены, а по ней к насосу или сифону.A water pump or siphon connected to the mouth of the drain generates less than atmospheric pressure inside it. Under the influence of the pressure drop above and inside the drain, a flow of water occurs along the filtering cover 2, located between the outer wall of the drainage tube 1 and the waterproof ring 3, then it enters through the slot 4 into the drainage cavity, and through it to the pump or siphon.

Устройство водонепроницаемых колец вокруг стыка на фильтрующей обкладке позволяет увеличить время устойчивого режима работы насосной установки.The installation of waterproof rings around the joint on the filter plate allows you to increase the time of a stable operation of the pump unit.

Claims

This invention relates to agriculture, namely land reclamation. A known water intake drainage of a water-amelioration ameliorative system using groundwater for moistening the dried territory is made of pottery tubes with a perimeter filtering material and a waterproof screen B. The drain also includes drainage tubes and a continuous filtering plate G21 The lack of these drains is uneven water intake in the drain along its length. The purpose of the invention is to ensure a uniform flow of water into the drain along its length, when water is drawn from it by a pump or a siphon. This goal is achieved by the fact that the drain is provided with water-tight rings installed at the top of the filtering plate at the joints of the tubes, alternating along the length of the drain width. The drawing shows the structure of the water intake drain. water intake drainage includes drainage tubes, filter cover 2 joints, waterproof ring 3, slots 4 between the tubes. Water intake drain works as follows. The water intake pump or siphon connected to the mouth of the drain creates inside, its pressure is less than atmospheric. Under the action of the pressure differential over the drain and inside it, water flows through the filter plate 2, located between the outer wall of the drainage tube 1 and the waterproof ring 3, then it flows through the slit 4 into the drain cavity, and through it to the Hf- cocy or siphon. The arrangement of waterproof rings around the junction on the filter cover allows an increase in the time of stable operation of the pumping unit. Claims of water intake, including drainage tubes and a continuous filter lining, characterized in that, in order to ensure a uniform flow of water into the drainage along its length, when water is drawn from it by a pump or siphon, the drain is fitted with water drains installed on it over the filtering plate the joints of the tubes are waterproof rings, made variable along the length of the drain width.
