Description

one

The invention relates to agriculture and can be used in irrigated agriculture when irrigating with closed pipelines.

The irrigation piping for subsoil irrigation, made in the pipe wall, is located} 1Ы. at a depth of 20-30 cm, in which irrigation water flows out through holes in the pipeline in the form of springs, forming a washout funnel in the soil.

A disadvantage of closed irrigation pipelines with known water outlets is that the pipelines are sedimented with soil that penetrates through the water outlets after the completion of irrigation. This occurs during the collapse of the walls of the funnel erosion and during the reverse hydraulic shocks in the irrigation pipe when the soil is sucked.

In order to prevent soil from entering the pipeline through the water outlets and to reduce the possibility of their clogging, the water outlet is provided with a hollow body inside which a partition is installed so that the water outlets of the pipeline and the body are located on either side of it.

The drawing shows a closed inlet irrigation pipeline, located under a layer of soil, section.

Vodovusk is a removable

a housing 1 with an internal partition 2. The housing is mounted on a closed irrigation pipe 3. The internal partition 2 is a limiter of the cavity 4 of the housing, in which

as the soil accumulates, earth is formed on the web, covering the opening 5. The water outlets 6 of the pipeline and the housing 1 are offset. This provides a predetermined pattern of water movement in the outlet.

The hole in the housing is located above the center of the pipe pipe, and the hole in the pipe is on the side. A funnel 7 is above the hull opening in the soil.

Nri watering water from the pipeline 3 through

the opening 6 enters the cavity under the outlet 1 and through the calibrated opening 5 and the erosion funnel 7 flows out to the surface. Thus, on the path of sedimenting or sucking soil particles, a sudden hydraulic expansion cavity is formed — a settler in which particles after irrigation are collected, and in the course of irrigation they are washed out due to turbulence in sediment. For reverse hydraulic shocks, the sump acts as a damper. Increasing the pressure loss during such irrigation water treatment allows to increase the size of the water outlets at the same flow rate, which reduces the possibility of clogging of the water outlets.

Subject invention

An irrigation pipeline water outlet for subsurface irrigation, vypolienny in the pipeline and pipe steak, so that, in order to prevent soil from getting into

the pipe line through the water outlet holes and reducing the possibility of clogging them, the water pipe is provided with a hollow body, inside of which the partition is installed so that the vacuum holes of the pipeline and the body are located on both sides of it.
