FIELD: construction.SUBSTANCE: invention relates to hydraulic engineering, namely, to water intake facilities, and may be used to take water from underground sources with shallow ground waters. The method to erect a horizontal underground water intake of combined design, comprising a water receiver and a water collecting well, consists in the fact that the main water receiver is made in the form of an open tray 1, covered on top with a metal net 2, above which they lay gabion mats 3 in longitudinal rows with drainage devices. Gabion mats 3 are made of light fascines, perforated pipes and a metal net. On top of gabion mats 3 along the tray they lay flexible mats 6, made of a drainage filler, which is made of tight rows of light fascines wrapped into a geonet. In the end of the water receiving tray 1 they arrange a water collecting well 9, equipped with a water intake pipeline 10. The proposed method may most efficiently be used in coastal and other water-bearing soil massifs with depth of occurrence of discharge-free level of ground waters of up to 7-10 m for water supply of rural settlements, small towns and villages.EFFECT: invention provides for efficiency of operation of a water-intake structure.2 cl, 5 dwg |
