Abstract

A presiometric procedure to establish foundations calculations, essentially characterized by a small diameter sounding, in which the special pressure measuring device is introduced, which is radially expandable, exerting a force field on the sounding walls and measuring the resulting deformations, this form being carried out the foundation test in the studied ground and the analysis of the pressure-deformation diagram registered throughout the test, allows to calculate the characteristics required by the foundation, this sounding being carried out in the manner described in firm terrain, but in the non-coherent, an injection of bentonite is used to support the walls forming this colloidal clay a gel of very thin thickness that keeps the surface in its position, presenting the device used two parts, the probe itself and the recorder of measurements, both parts being connected by tubes of plastic nature, the probe being constituted by a tricellular assembly that under an internal pressure dilates radially and transmits to the measuring organs the variations in the diameter of the sounding studied, being exerted by the two end cells or guard on the wall of the sounding a perfectly cylindrical field of stress over the entire length of the central cell, or measurement, this combination of cells is essential, because only a uniform field can allow a rigorous analysis of the phenomenon generated by the pressurization of the apparatus in full mass of the sole, being registered to the variations of diameter of the central cell, that measures the variations or volumetric, in a surface by a level indicator of the liquid and the pressure exerted, with the help of a metallic bottle of carbonic gas, it is registered in a manometer, translating the gross results of the test into a volumetric pressure-deformation diagram.
