Title (EN) METHOD AND DEVICE FOR IN-SITU MEASUREMENT OF GROUND HEAVE CHARACTERISTICS
(FR) PROCEDE ET DISPOSITIF DE MESURE IN SITU DES CARACTERISTIQUES DE GONFLEMENT D'UN SOL
Abstract:
(EN) The aim of this invention is to provide methods and devices for in-situ measure of ground heave characteristics. The sensor or device of the invention comprises at least two independently inflatable elements, one of which (111) allows for standard and traditional measurements of ground pressure in its original state, the other (112) being combined with fluid injection means (10) which allow for ground heave pressure measurements simultaneously with the impregnation of the ground until saturation, either at a constant pressure, or a constant volume.
(FR) La présente invention a pour objet des procédés et des dispositifs de mesure in situ des caractéristiques de gonflement d'un sol. La sonde ou dispositif suivant l'invention comporte au moins deux parties gonflables indépendamment l'une de l'autre, l'une (111) permettant des mesures normales et classiques de pression de sol dans son état initial, l'autre (112) associée à des moyens (10) d'injection du fluide permettant des mesures de pression de gonflement du sol simultanément à l'imbibition de celui-ci jusqu'à saturation, soit à pression constante, soit à volume constant.
