Abstract: The invention relates to a device for reinforcing a ground on which is disposed a loading structure, comprising a series of structural inclusions disposed in the ground and adapted to mechanically reinforce said ground, the inclusions having a diameter D comprised between substantially 0.2 m and 0.6 m, two adjacent inclusions being separated by a distance (A) such as 2D≦A≦10 D, the series of inclusions being made of a material having a Young's modulus of between 500 and 10,000 MPa, a load transmitting layer interposed between the ground and the loading structure, said layer having a Young's modulus less than the Young's modulus of the series of inclusions, a first nominal height between two adjacent inclusions of the series, and a second height less than the first nominal height at locations situated just above the series of inclusions, where the load transmitting layer is plastically compressed by the inclusions which partially penetrate within the load transmitting layer.

Abstract: Equipment for at least partially drying a zone of ground containing a liquid, the equipment comprising: a substantially air-tight membrane, covering the zone of ground to be dried, an embankment permeous to water and disposed under the membrane, first drain tubes disposed vertically in the zone of ground and in fluid communication with the permeable embankment, second drain tubes 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 a series of fluid input holes opened within the embankment for communicating with the fluid contained in said embankment, in order to evacuate the liquid collected from the ground and obtain an air depression under the membrane.
