METHOD OF CREATION OF CURTAIN GROUTING WITH FILTER WINDOWS AND BEAM WATER INTAKE Russian patent published in 2014 - IPC E02B3/16 

FIELD: agriculture.

SUBSTANCE: invention relates to the field of protection of groundwater and open water courses and is designed to intercept contaminated groundwater flows from the containment pond for production wastes, effluents of livestock farms, spills of oil and oil products from oil storage tanks, gas stations and others. The method comprises filling the main trench 1 with an impervious material 2 in the form of geomembrane with preformed windows 3, after which additionally perpendicular to the main trench 1 receiving beam trenches 4 are developed and filled with a sorbing-filter material 5. Then perpendicular to the main trench 1 additionally water drainage beam trenches 6 are dug and filled with the filter material 7. The receiving beam trench 4 at the inlet to the main trench 1 is equipped with a water receiving tank 8 and alsoa pump 9 for pumping from the upper layer of water 10 of floating contaminated soluble matters.

EFFECT: increased capture area by the beam water intakes of contaminated groundwater flow, as well as cleaning and outlet by the beam water intakes of a purified flow into the ground behind the curtain grouting.
