<p>The invention relates to an equipment for at least partially drying a zone of ground (1) containing a liquid, the equipment comprising: a substantially air-tight membrane (7), covering the zone of ground to be dried, an embankment (5) permeous to water and disposed under the membrane, first drain tubes (17) disposed vertically in the zone of ground and in fluid communication with the permeable embankment, second drain tubes (23) connected to a suction pump and laid substantially flat in the embankment. The second drain tubes are in fluid communication with the liquid collected in the first drain tubes, under the membrane, and comprise fluid input holes (25) opened within the embankment for communicating with the fluid contained in said embankment, in order to evacuate at least some of the liquid collected from the ground. Possibly, the equipment is also provided with third drain tubes extending substantially horizontally in the embankment, and comprising fluid input holes for an input of fluid therein, the third drain tubes being disposed in a zone of the embankment which is unsaturated with liquid, and being connected to an air suction means.</p> |
