UNDERGROUND HORIZONTAL WATER INTAKE OF COMBINED DESIGN Russian patent published in 2014 - IPC E03B3/06 E02B11/00 

FIELD: construction.

SUBSTANCE: invention relates to hydraulic engineering construction, namely, to water intake structures, and may be used to take water from underground sources in case of shallow ground water. The underground horizontal water intake comprises a water-collecting trench 1 and a water-collecting well 7. On the bottom of the water-collecting trench 1 there are gabion mats 2 with drainage devices laid in longitudinal rows. Gabion mats 2 comprise light fascines and perforated pipes laid in alternating rows and rolled into a gabion net. On top of gabion mats 2 along the trench there are flexible mats 5, made of a draining filler, which is made of tight rows of light fascines, rolled into a geonet. In the head part of the trench there is a rigid tray 6 of rectangular section, the cantilever part of which with a slope enters into a water-collecting well 7. Gabion mats with drainage devices are laid from the trench to the middle of the tray 6. The underground horizontal water intake most effectively may be used in coastal and flood-plain sections of waterlogged soils with depth of soil water free-flow level up to 7 m. The water-intake is designed for water supply of a small settlement, an agricultural enterprise, a farm and an individual household.

EFFECT: reduced labour intensiveness of construction and higher efficiency of operation of a water intake structure.
