ABSTRACT:
A device is provided for draining ground in depth. Each drain includes a tube having perforations in its middle part (1) with solid walls and closed at its lower part so as to form a cup (2), and with solid walls and open at its upper part (4). A siphoning tube (6) is permanently immersed by its lower part (3) in the cup (2), rises inside the tube (1) and leaves through a side duct (5) to drop down again towards an outlet (8). The outlet (8) is at the same level as the upper edge of the cup (2) so that the end (3) of the pipe (6) is always immersed and so that the siphon cannot be unprimed even during a dry period and requires no intervention.
