METHOD FOR DRAINAGE OF TERRITORIES ADJACENT TO WATER INTAKE WITH FLOODLAND AREA Russian patent published in 2017 - IPC E02B11/00 

FIELD: agriculture.

SUBSTANCE: method for drainage of the territories adjacent to a water intake with a floodland area is to determine the boundary of the periodic long-term flooding and the contour of the area 1. Within this boundary the drainage network branches 2 are laid by means of known excavating mechanisms, consisting of polyethylene pipes with increased strength. Above the pressure branches 2 of the drainage network, vertical partitions are installed with a positive slope in the soil thickness, which divide it into separate chambers. Between the partitions above the drains 2, filtering pipes with perforated openings are installed, the upper free ends of which are plugged, and the lower ends are connected to the drain housing 2. The filtering pipes are arranged in parallel above each drain 2 stepwise, starting with a smaller height at the plugged drain source to a greater height at the open end mouth of the drain 2. The ends of the drains 2 are directed into the base of the reservoir-collector 6. The reservoir-collector 6 is connected via the pipeline 7 to the well 8. The accumulating reservoir 10 is located above the reservoir-collector 6 and is divided from the floodland area 1 with the dam 11. Water is pumped to the accumulating reservoir 10 from the well 8 by means of the mobile pump station 9. Drainage flow is continuously fed into the accumulation reservoir 10, and then fed to the fields for irrigation to sprinkler machines.

EFFECT: method allows to increase the efficiency and maintaining the balance of the flood flow catchment in the floodland area, to reduce the construction work amount and to improve the environmental situation.
