WATER-INTAKE TUBULAR WELL Russian patent published in 2013 - IPC E03B3/00 

FIELD: construction.

SUBSTANCE: water-intake tubular well comprises a perforated pipe in soil. The pipe is installed with perforation at the section of a water-bearing horizon and is connected with an upper end with a suction channel of a vacuum pump. The vacuum pump is a water-ring pump, and its injection channel is connected with an injection pipeline. The pipeline comprises a vertical section and is aligned into a reservoir to collect water lifted from the well. The water-lifting pipe of the water-intake tubular well is equipped with a central tube reaching into atmosphere and with a lower perforated end lowered into water in the well. Perforation is arranged along the tube generatrix with increased diameter of holes in the top-down direction. The perforated section of the water-supply tube is located approximately at the static level of water in the well.

EFFECT: increased height of water lifting from a water-intake well by means of vacuumising.
