FIELD: reclamation.
SUBSTANCE: invention relates to the drying of agricultural land and can be used for drainage of construction sites. Low permeable soil drainage device comprises vertical perforated pipe 1 provided with conical drilled holes 2, the smaller base of which is directed inwardly of pipe 1. On both sides with respect to vertical tube 1 made further V-shaped filter tube 3, which are connected at the bottom of its base in the node pair with drains 6. Additional V-shaped filter tubes 3 are perforated hole 4 drilled obliquely to the bottom of the sole of plow layer 5. Standpipe drain receiving part 6 for interfacing with nodes of pipes 1 and 3, acquires an area that is greater than the yield of a cylindrical vertical pipe. There is a collision of streams and they are extinguished, reduced ground pressure at the bottom of the drain.
EFFECT: increases the intensity of removal of excess surface water and soil, improving ameliorative condition of the soil by increasing the total flow of water to the filter pipe.
