Abstract

The invention is intended to increase the efficiency of managing the water regime of drained lands. The aim of the invention is to increase the efficiency of the system and reduce the capital cost of construction. The system consists of regulating drains 1, 2 of the upper and drains 3 of the lower high-altitude Rus. Upper Rus' drains are coupled with a collector by 4 vertical taps. The lower Russ drains are connected directly to the collector. During floods and floods, the system discharges water from all drains through collector 4. When the groundwater level is 5 to the depth of the first upper Russ, the inflow to them stops and they stop working. The distance between the operating system is doubled. This leads to a decrease in the rate of decrease in the level of groundwater. The further decline in the depressive curve in time is even more slowed down, and between the drains 2 and 3 the decline in the depression curve is slowed down, since the inter-distance distance is slower. The bottom row can be increased four or more times. 1 il. (L with:

Description

The invention relates to land reclamation and is intended to increase the efficiency of water regime management of dried land.

The purpose of the invention is to increase the efficiency of the system.

The drawing shows regulatory drains, cross section.

The drainage system consists of alternating drains 1, 2 and upper drains. drains 3 lower parallel rusov. The drains of the upper Rus are matched with the collector by 4 vertical bends, the drains of the lower Rus are connected directly to the collector and limit the system.

Meliorative system works as follows.

During the flood and flood periods, there is an intensive inflow of water to the drains of all Rus and its discharge through the collector into the open network. When the level of groundwater drops to 5 the depth of the drainage of the first river, the inflow to them stops and they stop working. Thus, as in the dissipation of the operation of the drains of the first rus, the interdirectional distances on the second rus of the drains doubled, this leads to an increase in the resistance

at the entrance of water into the cavity of the drains of the upper 2 and lower 3 Rus.

The further depression of the depression curve in time is even more slowed down, and between the drains 2 and 3 the decline of the depression curve is completely slowed down, since the interdistance distance of the third line of the drains may increase

four times or more.

Thus, the inflow of groundwater to the drained area becomes greater, ciTTOK and the level of ground-TOBbix water in the vega; the period of time fluctuates between the drains of the second and third rivers, t. correspond to a given (calculated) rate of drainage.
