Directional press plant
The steerable press head displaces the soil as the boom advances. It is tracked above ground by a locating device. Deviations from the bore planning line can be read on the locating device and corrected by rotating the rod. In the target pit, the press head is replaced by an expansion. This expansion is retracted and the soil is thus expanded. At the same time, the attached pipe is pulled in. The use of drilling fluid can be dispensed with in directional pressing.
