FIELD: reclamation.
SUBSTANCE: invention can be used for drying agricultural fields, underground parts of buildings, closed depressions and local depressions. A method of closed depressions dehumidification includes two draining elements are laid and shallower depressions formed in a green area, which is provided with a draining mouth of the water inlets 3, 4 are connected via conduits to the collector 1. After laying open collector zone 1 set of possible pressurization of the reservoir 1 and pipe 4 is laid with a slope of not less than 0.002 with the placement of a water intake 3, also equal to the slope of the pipe 4. Water intakes 3 has a series of polyethylene perforated vertical tube 6 with stubs 7 at the top, with the location of the top of the filter backfill above the expected level of pressurization of the filter 5 when filling material 8 filling the space between the perforated tube 6 with plugs 7. Volume of each tube is proportional to the length of the hollow area of the mouth to the source. Use a perforated vertical tube with increased bandwidth with an inlet area of not less than 15 cm2 per meter.
EFFECT: increase in water intake capacity and operational reliability of draining water intakes at the exchange flow of water from the troughs in the pipe.
