DRAINAGE SYSTEM Russian patent published in 2015 - IPC E02B11/00 

FIELD: agriculture.

SUBSTANCE: drainage system comprises drains 1, an inlet collector 2, and an outlet collector 3, between which the storage tank 4 with a siphon 5 is placed. The descending branch 6 of the siphon 5 is brought to the drain well 7 on the level of the outlet collector 3. The float 8 with the plate 9, suspended on a holding traction 10 of the float drive with a valve 11 is arranged, respectively, at the level of the siphon neck 5. The float 8 is placed on the corresponding critical depth of groundwater for the soil and climatic and hydrological conditions of the area, in which the drainage system is located. In the wall 12 of the tank 4, a hole 13 is made for the intake pipe 14, through which the tank 4 is connected to the draining storage water intakes 15. The storage water intakes 15 are connected to the openings 16 of sections of the inlet collector 2 at the location of the drains 1. When mounting the filter storage water intakes 15 the filling of waterproof materials 17 is used, such as sand, gravel, slag or synthetic wastes of light industry.

EFFECT: invention enables to automate fully the process of maintaining the level of groundwater at the level corresponding to the critical, ensures the supply of a certain amount of water from the groundwater in the root layer of soil, which increases moisture reserves for crops and enables decrease partly the irrigation rates, which provides saving water resources, the necessary regime of moistening and aeration of soil is ensured by creating an optimal level of groundwater in the different phases of plant vegetation.
