Abstract

The invention relates to land reclamation and can be used as a drain-wetting system. The aim of the invention is to increase the efficiency of the reclamation system and ensure the rational use of hydraulic engineering by S.Markova, M., water while maintaining soil fertility. For this purpose, there are routing tracks per kilogram at the irrigated site through two (three) irrigation furrows. Between the route wheels, closed drains of semicircular tubes are laid at a given depth. In the upper wall of the semicircular drainage pipes there are perforations. The top of the drainage pipe and wall of the trench are sprinkled with sand and gravel. The trench is attached in V-shape. To supply water to the drains, their source part is equipped with stand pipes. For sluicing, the mouth of the drainage collector is provided with a hydrant. 3 il.

Description

The invention relates to land reclamation and can be used as a drainage and humidifying system.

The purpose of the invention is to increase the efficiency of the system and ensure the rational use of water resources while preserving soil fertility.

Fig, 1 shows a general view of the reclamation system; figure 2 - cross-section of the furrow with drains; on fig.Z - longitudinal section of the furrow with drains.

The ameliorative system includes an irrigation network 1, closed drains 2, a collector 3, a water intake 4, pipeline 5, irrigation furrows 6. In irrigated areas, after about 2-3 furrows, route tracks 7 are laid, and between two wheels 7, drain pipes 8 are laid under the furrow with a non-perforated lower semicircular part 9 and an upper flat wall 10 with perforations 11. On top of the drainage pipes are poured sand and gravel

a mixture of 12, a layer of which is applied to the walls of a trench 13 having a V-section. Drainage pipes 8 are connected to a collector 3 by means of drainage pipes 14. To supply water from the irrigation network 1 to drains 2, there are nozzles 15 on the network, and 16 pipes on the pipe 5, which are connected to stand pipes 17 as necessary.

To regulate the level of water in the collector 3, it is equipped with a hydrant 18. For supplying water from the water intake 4 to the irrigation network 1, the system is equipped with a pump 19. The suction pipe 20 of which is lowered into the water intake 4, and the discharge 21 to the irrigation network 1.

The reclamation system works as follows.

In the winter-spring period, precipitation, falling in the form of rain and snow, accumulating on the floor surface, is absorbed into the soil. After complete saturation of the soil moisture enters the sand and gravel slate on the wallXJ

Kah trench 13 and dusting 12 and through the perforation 11 penetrates into the pipe 8. In the same way (but only below) get into the drain 2 and groundwater.

Further, along drains 2, water flows to collector 3, through which, as flow, it enters the water intake 4.

In spring, before sowing, soil moisture is regulated by hydrant 18 on collector 3. When soil moisture is insufficient, hydrant 18 is closed, which contributes to the accumulation of water in collector 3 and in drainage 2 and through them to saturation of soil.

When the soil is excessively wetted, hydrant 18 opens until the required soil moisture is established,

During the growing season, the hydrant 18 is closed and water is supplied from the sprinkler 1 through nozzles 15, 16, pipeline 5, pipe-supports 17 is fed into drain 2. As the drainage is filled, due to the absence of outflow, the water passes through perforation 11 into sand-gravel bedding through which it moistens the soil and nourishes the plant root system, i.e. Subsoil moistening is carried out. When soil moisture is insufficient, water from irrigator 1 is fed through irrigation grooves through nozzles 15,16 and due to moistening from below and above the soil is quickly saturated with moisture.

When excessive soil moisture is detected, hydrant 18 opens to reduce the degree of soil moisture within the optimum range. In this case, excess water flows through drain 2 and collector 3 enters the water intake 4, where all the excess moisture accumulates.

As required, water can be supplied from the water intake 4 to the irrigation network 1 by means of a pump 19.

Thus, a closed cycle of using water resources of nature with maximum efficiency is achieved.

When tilling the soil before and after the growing season, agricultural machines move along established route wheels and m wheels 7. The presence of a constant route track in the field contributes to the improvement of the soil state by completely eliminating the possibility of it being compacted by the wheels and caterpillars of the machines.
