The invention relates to a process for backfilling a functional element introduced into a borehole, in which process a backfilling material is injected into the borehole by an injection pump arranged outside the borehole via at least one injection pipe, which is routed to the foot of the functional element, preferably as far as the base of the borehole, wherein, during the injection operation, the injection pressure and the injection rate are continuously measured in order to determine geometric or physical properties of the borehole, of the subsurface and/or of the backfilling material. Furthermore, the invention relates to an arrangement for carrying out the process according to one of the preceding claims, comprising a borehole, a functional element inserted into the borehole, at least one injection pipe in the borehole, which leads as far as the foot of the functional element, preferably as far as the base of the borehole, and an injection pump, which is arranged outside the borehole, can be charged with a backfilling material and to which the at least one injection pipe is connected, wherein at least one pressure sensor is arranged between the injection pump and the injection pipe, and wherein at least one flow rate sensor is also arranged between the injection pump and the injection pipe. |
