Abstract
The invention relates to a method of monitoring the diameter of columns made in the ground by jet grouting. In the method, a measuring instrument is provided which is constituted by a tubular element of length substantially equal to the length of the column, said tubular element being fitted with a plurality of emission electrodes for creating an electric field, and with a plurality of measurement electrodes for measuring the resulting potential differences; a reference borehole is made in the ground; an axial borehole is made in the column to be tested; said measuring instrument is inserted in the borehole in said column and voltage measurements are performed at different depths; and said measurements are processed.
