METHOD FOR WATER-INTAKE STRUCTURE ERECTION |
摘要 |
FIELD: water supply facilities, particularly water-intake structures to supply underground water for domestic water supply, hydraulic engineering and irrigation purposes. ^ SUBSTANCE: method involves constructing horizontal drains; forming and equipping shaft well; creating additional well in parallel to one adapted to take water from lens arranged on salt ground water, wherein depth of well for salt ground water delivery is 1-2 m greater than lower level of fresh water lens. Horizontal drains and lower end of water-lifting pipe in shaft well is at upper salt ground water level. Additional well is provided with draining net to remove salt ground water for irrigation of areas with salt-resistant plants located beyond fresh water lens. Fresh water is produced from lens in amount of 45-85% of annual precipitation volume. In the case of salt water ingress in shaft well water is differentially extracted from main and additional wells. ^ EFFECT: provision of all-the-year-round fresh water supply and creation of favorable conditions for salt-resistant plants growing in neighboring area. ^ 1 dwg |
