Abstract
The invention relates to a method for determining the radius of a pile in the ground that can be produced by means of a jet-grouting process, comprising the steps of: introducing at least one level-measuring stick into the ground; sinking a jet-grouting tool () down to a defined distance from the level-measuring stick (), the distance being less than a maximum range R of the grouting jet; pulling the jet-grouting tool () while performing a rotating or swivelling motion with the grouting jet activated, thereby producing vibrations as the grouting jet passes the level-measuring stick (); and recording a signal representative of the vibrations at the at least one level-measuring stick () by means of a sensor () that is fastened to the level-measuring stick (). The invention also relates to a corresponding arrangement () for determining the radius of a pile in the ground that can be produced by means of a jet-grouting process.
