SU1250219A1 - Intrasoil irrigation system for sloping ground - Google Patents

Description

The invention relates to agriculture, in particular to irrigated agriculture, and can be used for the irrigation of agricultural crops on sloping lands using surface run-off water or irrigation water.

The purpose of the invention is to reduce the cost of building a system, the non-pressure distribution of water in humidifiers, regardless of the mode of its entry into the system and the slope steepness.

FIG. Figure 1 shows the intra-irrigation system for sloping lands, a plan view; in fig. 2 shows section A-A in FIG. 1 (vertical section along the axis of the irrigation pipeline); in fig. 3 shows a section BB in FIG. 2 (vertical section along the axis of the ditch); in fig. 4 shows a section B-B in FIG. 2 (vertical section along the axis of the humidifier).

The subsurface irrigation system for sloping lands has a transport network in the form of ditch shafts consisting of embankment 1 and notch 2 with bridges 3 and organic filler 4. There is porous dumping 8, which is separated by a length of waterproof soil bridges 9. Porous dumping is made of stone

five

n to the sole of the arable layer and is under the arable layer 10.

The dumping can be separated from the ground from four sides by a waterproofing layer 11 made of a polymer film, which is cut by the working body of the mole when cutting blood. The dumping in the transverse direction permeates molehills 12, which have a slope, preventing their silting and erosion. The system works as follows. Mudflow or stormwater flowing down the slope is intercepted by ditch shafts and diverted to irrigation pipe filters. Passing through the organic filler and filter, the water is cleaned from suspended particles, flows through the pipeline into the first section of the dumping and spreads over the humidifiers in the subsoil. If the water flow is greater than the absorption, then the excess water is discharged through the pipeline to the underlying cell, and so continues until

0 as long as there is no equilibrium in the absorption of water through humidifiers. In this way, the system carries out the non-pressure distribution of water in humidifiers and ensures the rational use of irrigation water regardless of

slope of trench and flow rate of water flow. The proposed system can function as a system inside the soil irrigation, if mechanical water supply to the cavity of the drainage structures from the water source is provided.
