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

FIELD: construction.

SUBSTANCE: invention relates to hydraulic engineering construction, namely, to water intake structures, namely, to water intake structures, and may be used for water intake from underground sources with shallow beds of underground water. The method of erection of an underground horizontal water intake of a combined structure, including a water receiving trench 1 and a water collection well 7, consists in laying of gabion mats 2 in longitudinal rows on the bottom of the water receiving trench 1 with drainage devices. Gabion mats 2 are made of light fascines and perforated pipes, laid in alternating rows and rolled into a gabion net. On top of gabion mats 2 along the trench they lay flexible mats 5, made of a drainage filler, which is made of tight rows of light fascines rolled into a geonet. In the end part of the trench there is a rigid tray 6 of rectangular cross section, the cantilever part of which with an inclination enters into a water collection well 7. Gabion mats with drainage devices are laid from the trench to the middle of the tray.

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