Irrigation system with irrigation on a slope

 

The invention relates to the field of irrigation of agricultural crops and can be used in the irrigated plot with a slope of 0.02 to 0.08 to different soil and climatic conditions, mainly for irrigation systems on a wide and long strips with longitudinal separation rollers and bezuslovnymi hollows. In the irrigation system from watering down the slope, including pipelines wastewater (SW) and clean water, the construction of mechanical treatment (ST), pond drive (MO), the slope with irrigation blocks, educated longitudinal separation grooves - rollers (KV) passable for agricultural technology (ART) profile, valves and sprinklers, butylone hollow passable for (ST) profile, hill ditch and placed on the backup site automated pumping station discharge pipeline for pumping storm water (MO), slopes (KV) made with a coefficient of laying m=45. The bottom of the inner reserve InBPeach (KV) performed a width of from 1.5 to 4.5 m Building depth Hpeach (KV) is made from 0.2 to 0.3 m Building height of the embankment of the roller over the surface of the irrigated strip HNV=0,1

The invention relates to the field of irrigation of agricultural crops and can be used in the irrigated plot with a slope of 0.02 to 0.08 to different soil and climatic conditions.

Known irrigation system from watering down the slope for wastewater treatment [1], including pipelines wastewater and clean water, mechanical treatment of wastewater, pond drive, the slope with irrigation blocks, educated longitudinal separation rollers passable for agricultural machinery profile, valves and sprinklers with facilities for the supply of irrigation water for irrigation blocks, butylone hollows also passable for agricultural machinery profile, arranged Nagorno ditch, and on the backup site is additionally arranged an automated pump station and pressure pipe for pumping storm water pond drive.

The separation rollers designed to hold on the.

Known construction permanent passable and temporary double not passable for agricultural machinery profile separation roller [2].

Permanent separation roller passable for agricultural machinery profile suit or imported soil, or occiput from local soil using a grader.

The device is a permanent separation roller of the imported soil is carried out without reserves, but it requires considerable effort and money on ground transportation.

In dumping roller grader from local soil occurs the problem of elimination of external pavlicevic reserves, especially in the irrigated plot with a slope of more than 0.02. But to leave these reserves cannot: when watering these depressions rushes the main flow of water supplied to the strip, which can lead to uneven wetting of the surface irrigation stripes, and even to the manifestations of soil erosion.

Temporary double not traversed for agricultural machinery separation roller slept the ditcher COR-500. The width of the roller 4,36 m, coefficients of shallow slope m=1.0 and m=1,7. Roller occiput before watering and zaravnivayut before hay that create the spit and susceptible to overgrowing weeds.

The essence of the invention lies in the fact that the proposed permanent separation roller slept grader at the expense of soil internal reserves, and the slope of it is made with a coefficient of laying m is from 4 to 5, which makes the groove-roller passable for agricultural machinery, and 8.7% of previously excluded area shall be planted with perennial grasses and inclusion in the grasslands.

Inside the grooves of the roller after every 40...60 m which is arranged jumper to prevent sbeinati flow of storm water flowing from the surface of the groove of the roller, and discharge them into the irrigation line.

In the drawings shown: in Fig. 1 - scheme of the irrigation unit of the irrigation system from watering down the slope; Fig. 2 is a fragment of the groove of the roller in plan; Fig. 3 is a cross section 1-1 of the groove of the roller of Fig. 1 and Fig. 2 and taken notation:BP- the width of the bottom of the inner reserve, m; hBP- the depth of the inner reserve, m;kV- the width of the groove of the roller, m; Hpconstruction depth of the groove of the roller, m; HNVconstruction height of the embankment of the roller over the surface of the irrigated strip, m; m is the coefficient of shallow slopes; NSPconstruction height which jumpers, m;SP- selnau system with watering down the slope, it is shown in Fig. 1, includes fill 1, 2 culverts, the dividing grooves of the rollers 3, butylone trough 4, column 5, which crosspieces 6, stormwater overflow tank 7 and the collector 8 for the discharge of storm water to the backup site, flowing from the surface irrigation block.

The system works as follows.

Before the next watering produce mowing grass with ordinary equipment hay. The movement of her in the irrigated area is unobstructed in all directions, so as sprinklers and groove-rollers have a profile that is taken for all kinds of agricultural machinery. The use of square grooves-roller passable profile for haymaking increased utilization of square hay section 8.7%.

After the hay produced the opening of the floodgates, carrying water directly to the appropriate band set for the calculation of mode usage.

The discharge of drainage and storm water bands is performed using stormwater overflow tank 7 and the collector 8.

Valve is made in the form of concavo-concave lens arranged in spherical belt. Valve is manufactured from material having density smaller than density of water, in particular, valve may be made from cork of 0.2-0.3 t/m3 density. Valve is arranged in casing between cuffs and is adapted for alternating contacting through cuffs with projections oppositely arranged inside casing cavity. Projections are made in the form of spherical segments, with radius of spheres of segments being smaller than radius of spheres of concavo-concave valve lens. Difference between radii of projection sphere and that of spheres of concavo-concave valve lens is equal to thickness of elastic cuffs. Channels on apexes of cover and casing projections are extending in radial direction toward inlet and outlet openings.
