Abstract

The invention relates to irrigation and drainage construction, primarily to drainage of land for agricultural purposes with automatic control of groundwater levels. The purpose of the invention is to reduce the water supply network of the nets and increase technological reliability. The automatic mode of operation of the system is ensured by the flow-through of a closed regulator, to its network consisting of a combined drainage and humidifying collector 5, a floor arranged along a slope, to which drainage collectors 6 are connected via water intake wells 6. Waste wells on the axle 1 are equipped with automatic cooling regulators of levels of unilateral action, and intermediate wells are equipped with regulators of 23 levels of bilateral action. The level controllers 23 have floats 26 provided in the upper part with water-filled containers 27 with calibrated holes 31. 7 sludge. 25 28 27 (О О) with ГЧЭ оо о: shchi2.1

Description

one

From () D)) Distinction refers to hydrotechnical- KOi i mechloration, and most importantly to the drainage of land in agriculture.

The purpose of the invention is to reduce the water network and improve process reliability.

FIG. 1 shows a schematic plan of a drainage and humidification system; in fig. 2 is a longitudinal section through the drainage and humidifying collector (section A - A in FIG. 1); in fig. 3 - a section along the lower drainage collector (section B - B in FIG. 1); in fig. 4 is a section through the drain (section B-B in FIG. 1); in fig. 5, 6, and 7 — installation and design of automatic regulators of groundwater levels in wells in a drainage dampening collector.

The osusha-humidifying system consists of a water receiver-water source 1, water-conducting channels (water-supply 2 and waste 3), gateways-regulators 4, closed collectors: drain-water-1, about 5, drainage 6 and 7 drains, water-receiving 8, water discharge 9, middle 10 and secret 11 wells, automatic 12 level equlators, installed respectively in the position of the humidification and dehumidification regulators 14, the designs of which include a low flange 15 with a tunic, a locking disc 16 with a bracket 17, a cylindrical gate 18 s forward a bushing, an L-shaped lever 9, t gu 20, a float 21 and a locking washer 22, automatic regulators 23 of a two-way action, the structures of which include a housing, locking discs 24, t gu 25, a float 26 with an open water supply capacity 27, lock washer 28, telescopic tube 29, counterweight 30. Capacity 27 has a calibrated water outlet 31.

Drainage and wetting system works as follows.

When the groundwater level (GWL) decreases, the level changes in the level below the predetermined level in the water intake well 8, where the level regulator is set to the position of adjustable moisture 13 (Fig. 2, 5), the float 21 of which, following the level, moves along Tue 20 downwards and, separated from the locking washers1 22, which fix the given UHT on the lower part, removes traction force from the L-shaped lever 19 and the presser from the gate 18, which is displaced under the action of water pressure from the water supply channel 2 in back position, open yva water path passing through the flange 15 into the well 8, osushi- Tel'nykh-humidifying manifold 5 and further to the drain collector 6, and therefrom to drain 7 and the soil to the groundwater ponolnenie (FIGS. 3, 4). Simultaneously with the intake well 8, the levels are reduced.

water and in the middle wells 10, where two-way level regulators 23 are installed (Figs. 2, 7), whose floats, following level 25, from 5, are from the lock washers 28 fixing the given GWL, and remove the traction forces from thrust 25 and clamping from locking discs 24, which under the action of the counterweight 30 move downwards and open the holes in the housing of the regulator 23, pass water to the mid wells 10 and then fill the collectors 5 and 6 and drain 7 and infiltrate them into the soil. In this case, the level regulator in the waste well, the well 9 is closed (Fig. 6). When 5 meters are lifted, GWL on all sections of the floor to a predetermined float of regulators 23 and 12 (Fig. 2) in wells 10 and 8 move up to the stop into the lock washer and, dragging along with it, and the associated transmission the system, respectively, the valves are moved, which block the through openings of the regulators, and the flow of water into the closed control network is stopped.

With excessive natural moisture

The upper level of the groundwater level is raised and the water level in the closed regulating network (Fig. 3, 4) and in the middle wells 10 changes accordingly, where the regulators 23 are installed at the inlet wells of the wet-humidifying collector 5.

A 30-level double-acting action (Fig. 7), through a telescopic tube 29 of which fixes a given UHV upstream, water is drained into an open tank 27, the latter, being filled with water, floats 26 and floats 26 down, opening from locking washer 28. In this case, the ha ha 25 under the influence of the counterweight 30 moves together with the locking discs 24 down and opens the through holes in the housing of the regulator 23 to bypass the drainage drain from the upper to the lower reach and further to the well 9, where are you The inlet mouth of the collector 5 is installed with a level regulator in the position of adjustable drainage 14 (FIGS. 2, 6), a float 21 of which floats and, abutting against a washer 22, pulls the rod 20 and the lever 19 upwards, moving the shutter 18 to the lower position , forming a passage opening between the flange 15 and the disk 16 for the passage of drainage outflow in the discharge channel 3.

When the discharge from the floor of the excess drainage outflow is completed, the regulator in well 9 is closed, the preset level is set in the middle wells 10. At the same time, the water supply through the telescopic pipe 29 on the regulator housing 23 (Fig. 7) is stopped. The container 27 on the float 26 is emptied through the calibrated orifice 31 at its base, revolving

having established the buoyancy of the float 26, which moves up along the track 25 upward and rests on the lock washer 28, entrains the trap 25 and the locking discs 24 with it, which block the bore holes in the regulator housing 23, stopping the flow of water from the upstream to the lower.
