Abstract

FIELD OF THE INVENTION The invention relates to hydraulic engineering applications for land drainage. The purpose of the invention is to increase the efficiency and reliability of CHCTet-b in the drying and wetting regimes, increasing the uniformity of the water regime. The system includes non-sloping drains 1 and drainage 1; 2 s and transporting 3 collectors. Drainage 2 and transporting 3 collectors are made with zero slope and are looped together by means of open wells 4 and wells of level controllers 5. Transporting collectors 3 have a two-way exit to open channels 6. Due to laying of drains 1, transporting 3 and drainage 2 collectors with zero slope, as well as the closeness of the collectors and bilateral inlet to the channels 6 in the field creates a pronounced water regime. The water mode is set by adjusting the regulators in the wells.

This invention relates to hydraulic structures for draining land.

The purpose of the invention is to increase the efficiency and reliability of the system in the drying and humidifying regimes, increasing the uniformity of the water regime.

In the drawing, a schematic of the image — drainage and humidification — this, TJeMa,

The system includes flat drainage 1, drainage 2 and transporting 3 collectors, open wells 4, a boat. Level 5 regulators and open channels 6. Drainage 2 and transporting 3 collectors are zero-sloped and looped together by means of open wells and regulator wells. Level 5 tori. Transporting collectors have Bilateral exit to open channels 6.

The proposed system works very little.

When rising groundwater levels (GWL) on any part of the floor above the permissible drainage, excess water is drained by drains 1 to collectors 2, from where it can be supplied for moistening along drains 1 to command sub-dried areas or to one of the transporting collectors 3 Of these, water through the collectors 3 flows to other parts of the drainage system or is discharged through wells 5, in which the regulators maintain a given level into an open network.

In the case of a decrease in the GWL in the field, when due to the redistribution of the flow the moisture in the soil is not compensated for, the water comes from the open

nets through wells 5 for moistening. At the same time, it enters through one or all of the wells 5 and spreads in any direction to compensate for the lack of moisture in the places of the greatest reduction of GWL in the areas of the floor.

Thus, due to the laying of drains and collectors with zero slope, as well as the closure of collectors and bilateral inlet to the channels on the field, which is served by the drainage and dampening drainage system, equalized water regime is created, which is set by adjusting the regulators in the wells 5.

When the drainage collectors are deformed or silted in one of the sections, the proposed system is operable due to the ringing of the collectors and their bilateral entry into the channels.
