METHOD TO CREATE COMBINED WALL DRAINAGE WITH VERTICAL COLLECTORS Russian patent published in 2014 - IPC E02B11/00 E02D31/02 

FIELD: construction.

SUBSTANCE: previously they make a horizontal circular drainage 1 with a tubular drain having gravel fill and wrapped in geotextile. Then a bed drain 3 is arranged under the bottom of the basement with filtering fill from crushed stone. A sink 4 is equipped with fill from coarse-grained sand. Walls 6 and the bottom 7 of the basement are hydraulically insulated. Piles 8 are driven, and a groove-and-tongue wall 9 is arranged. Perpendicularly to the horizontal drains 1 tightly to the groove-and-tongue wall 9 at the rated distance they arrange vertical perforated plastic pipes 2. Vertical collectors 2 are wrapped by a protective filtering material and are combined into a single system. For quick reduction of ground water level they apply forced pumping of water by a pump 10 from vertical collectors 2 with its further discharge into the horizontal circular drainage 1.

EFFECT: increased efficiency of drainage operation.
