HORIZONTAL UNDERGROUND WATER INTAKE OF COMBINED DESIGN Russian patent published in 2014 - IPC E02B11/00 

FIELD: construction.

SUBSTANCE: invention relates to hydraulic engineering, namely, to water intake facilities. A horizontal underground water intake comprises a water receiving tray 1 with a metal grid 2, on top of which there are gabion mats 3 laid in longitudinal rows with drainage devices. The metal grid 2 is arranged on top of the tray 1. Drainage devices of gabion mats 3 are made of light fascines 4 and perforated pipes 5 laid in layers and wrapped into a gabion net. On top of gabion mats 3 along the tray there are flexible mats 6. Mats 6 are made of dense rows of light fascines wrapped into a geonet. At two sides perpendicularly to the tray 1 and with an inclination to it, at a certain distance from each other, there are dense rows of additional water-collecting lines 7 of the tray 1 from gabion mats 3. Additional lines 7 of gabion mats 3 enter the water-receiving tray 1 with the help of short channels 8. Channels 8 are arranged on top of the tray 1 boards and with direction of the drain inside the tray 1. At the end of the water-receiving tray 1 there is a water-collecting well 9 equipped with a water-intake pipeline 10. Around the well 9 and on top of the loose soil along the line of the tray 1 there is a safety screen 11 from clayey soil.

EFFECT: invention provides for water intake from underground sources in case of shallow ground waters.
