Pilot drive ND 150 - DN 400
„Building for people and nature“ - no empty words for SONNTAG. Subterranean driving
reduces the adverse effects which arise from a project and save resources. Therefore,
we intend to install collectors and house service connections trenchless, as often
as possible.
In this area we work with the “pilot drive”. In ground which can be displaced, we
press a pilot pipe to the target groove under permanent optical control of bearing
and inclination. The pilot pipe is used as orientation for the really driving and
lying of the adapter pipes. Compared to the open laying of pipes the construction
period will be reduced considerably.
