The method involves having a pipe retained against opening (17) of an adjacent construction unit (18). A hydraulic oil switches over a medium disconnecting switch and a pressure multiplicator (4) produces a pressure condition. A static sounding rod (2) is brought into a tubing section which can be expanded outside by the retaining opening (17). The static sounding rod is fastened by seals (20, 21) in an area between the tubing section and the static sounding rod. The filling time required for the pressure multiplicator is between 1sec and a maximum duration of 20seconds. An expand pressure of the hydraulic pressure oil is increased over time. The expansion time is between 1 s and maximally 10 s. The expand time is diminished automatically. The expand pressure is produced from 2000 bar to 4000 bar. An independent claim is included for a device. |
