Abstract

The invention relates to land reclamation and is intended to regulate the water-air regime of drained land. The aim of the invention is to reduce capital costs and the amount of work during construction, and to increase the efficiency of the system during operation. The drainage system consists of upper and lower level regulating drains, arranged in a checkerboard pattern, collector 3 and open channel. The lower level drains are connected directly to the collector, and the upper one - by vertical branches. A two-layered arrangement of drainage drains in a checkerboard pattern and their parallelism ensures a rapid discharge of water for the period of sowing to the level of the upper rushes and sharp braking to the lower rus. This allows you to retain moisture for a long time dp feeding the soil layer with moisture. 1 il. (L 1532 N5 sk OS L ate 1

Description

The invention relates to melioracin and is intended to increase the efficiency of the operational management of a drained-land water regime.

The purpose of the invention is improving the efficiency of operational regulation of the soil water regime, reducing capital costs during construction by reducing the volume of land works, as well as improving the system's efficiency during operation.

The drawing shows a drainage system, a general view.

The drainage system consists of upper and 2 lower levels of adjustable drains, a collector 3 and an open channel 4, on which slides-controllers can be placed. The drains 2 of the lower one are connected directly to the collector, and the upper one - to the vertical branches 5,

The drainage system works as an elec- tronic image.

During the flood and flood periods, there is an intensive inflow of water to the drains of both levels and its discharge through the collector 3 into channel 4. When the groundwater level drops to the depth of the drainage of the upper altitude and the lower level, the inflow to them decreases. and they stop working, which leads to an automatic increase in the distance between the

melt drains of the lower level) and reduce the inflow of water to the drains. As a result, the influx of groundwater ESP into the drained area becomes more outflow, and the groundwater level rises -. With the rise of groundwater above the drains of the upper level, the inflow of water to the drains increases, and the level of groundwater decreases.

Thus, the ground waters automatically, without the fate of operating personnel, oscillate between the drains of the lower level and the estimated rate of drainage, periodically moistening the root layer during the entire vegetation period. When the groundwater is melted by the drains of the upper and lower levels, intensive aeration of the root layer of soil occurs through the drains of the upper level.
