METHOD TO REGULATE UNDERGROUND WATER STORAGE (VERSIONS) Russian patent published in 2005 - IPC

FIELD: water supply.

SUBSTANCE: proposed method comes to creating watertight barrage within the limits of zone of influence of water intake, provision of reduction of underground water runoff beyond the limits of barrage, accumulation and discharge of underground water in underground water storage. Barrage to partially or completely overlap water-bearing horizon in power and width is formed by freezing part of ground of water-bearing horizon. According to first version, freezing is carried out by means of heat exchanger communicating with atmosphere, and at drop of air temperature below 0^oC, natural or forced ventilation is effected, intensity of ventilation and corresponding change of sizes of freezing zone, depending on position of levels of underground waters in underground water storage are regulated. According to second version, freezing is carried out by means of sealed heat exchanger filled with coolant with provision of circulation of coolant in heat exchanger, intensity of circulation is regulated and sizes of freezing zone are changed depending on position of underground water levels in underground water storage.

EFFECT: provision of possibility to control hydrogeological conditions at reliable water discharge in required volume, prevention of underflooding of engineering structures.
