This invention relates to land reclamation and (plot to be used to control the level of groundwater in drainage systems.

The known regulator of the water backwater in the drain, including a shutter in the form of an annular inflatable chamber, mounted on a tube that is concentrically mounted in the drain and communicated with a hydrostatically uranium-hung tank disposed in an airtight well P.

The disadvantage of this regulator is the local overlap of the drain, which does not exclude the entry of groundwater into it and the latter’s return to the ground through perforations in the drain section in front of the regulator, which leads to an uneven distribution of groundwater and a decrease in the efficiency of the regulator.

Closest to the present invention is a B0fls ground leveling device containing a hollow elastic shutter in communication with a control element placed in the well and made in the form of a sylphon with a float. ..

The disadvantage of this regulator is also the local overlap of the drain, which does not exclude the entry of groundwater into it and the latter’s return to the ground through perforations in the drain section in front of the regulator, which leads to an uneven distribution of groundwater and a decrease in the efficiency of the regulator.

The purpose of the invention is to increase the efficiency of the controller "

The goal is achieved by the fact that the elastic chamber — the shutter of the regulator is made in the form of a stocking, is fixed on the source of the drain, is located along the entire length of the drain, with the possibility of blocking its water intake holes when filling with the working medium; allow all water intakes to be blocked at the same time

the holes, excluding the entry of ground water into the drain and its return to the ground through the water inlets, significantly increasing the regularity of soil water control, depending on the level of ground water in the well with the bellows, the proposed gate can assume an intermediate position.

partially overlap the cavity of the drainage pipeline in accordance with the required intensity of drainage from the soil

The application of the invention improves the accuracy, speed and quality of regulation of the water regime of the soil, which creates more favorable conditions for the growth of agricultural crops on artificially drained lands.

Fig „1 shows the scheme of regulating drains in the plan with the location of the soil wells; in fig. 2 - camera-shutter controller in the open polo. life; FIG. 3 shows the shutter-chamber of the regulator in the closed position; in FIG. ) - ground well with bellows with open (main line) and closed (dotted line) gate

The drainage intake regulator consists of an elastic shutter in the form of a hermetic chamber 1, made in the form of a stocking, filled with working medium 2 (for example, water or air), fixed in the source part of the drain 3 and placed along the entire length of the drain; all its water inlets. Chamber 1 communicates with a bellows 5 having a float 6 located in a soil pit 7,

The regulator works as follows.

When the water level in the soil pit 7 rises, the float 6 rises to its upper position, stretching the bellows 5 and increasing its volume, which helps to move part of the working medium 2 out of the sealed chamber 1, the volume of which decreases, freeing the drain cavity 3 and opening the water intake holes A. As a result, its water intake capacity increases, and the water flow into the drain cavity 3 increases ,. When the water level in the soil well 7 decreases, the float 6 is lowered and compresses the bellows 5 with its gravity, moving the working medium 2 into the sealed chamber 1, which, expanding, closes the water inlets 4, stopping the flow of ground water into it. chamber 1 is removed from the cavity of the drain 3.
