METHOD TO BUILD WELL TO PRODUCE WATER FROM SOIL WATER-BEARING BED Russian patent published in 2015 - IPC E03B3/06 

FIELD: construction.

SUBSTANCE: to build a well to produce water from a soil water-bearing bed they drive a well 1 to design depth, arrange a soil filter from filtration material 7, and a pump 5 is installed in the well 1. The well 1 is driven with thrust of a perforated pipe 2 with a non-perforated lower end 3 against its bottomhole and wash-out of soil 4 under it with the pump 5. The filtration material 7 is chosen so that dimensions of its grains are more than the diameter of perforations in the perforated pipe 2. Arrangement of the soil filter is carried out simultaneously with well driving, for which purpose the filtration material 7 is leaned against the outer surface of the pipe 2 leaving the soil 4.

EFFECT: increased efficiency of well erection.
