With the electronic hose-levelling instrument SDV-WW for microtunneling,
Centerline is able to supply an economical alternative to conventional
navigation systems which require a free line of sight through the whole
tunnel. The system is designed for the determination of the vertical
position of microtunneling machines in small diameters (> ID300mm) as
well as for long-distance and elevation-sensitive drives.
Important features of our SDV-WW are the well-proven
operating principle of the electronic hose-levelling instrument, the
tough and reliable system layout and the user-friendly handling. The
high-quality design of the electronic hose levelling instrument
guarantees a reliable and precise determination of the current
elevation of the drive down to the millimetre.
Furthermore, the SDV-WW shows the vertical deviation
of the TBM with respect to the DTA, the inclination and roll of the
machine and the current chainage of the advance numerically on a display.
Especially in long-distance drives and in very small diameters, completely
new perspectives are opened because - in contrast to optical measuring
equipment - absolutely no visual connection is necessary between the
boring machine and the starting pit.
Enormous advantages result especially for compressed-air drives with open
face shields and airlock chambers behind the machine. Temperature differences
inside the pipeline do not influence the measurements. The SDV-WW provides
simple, autonomous, rapid and reliable navigation of Advances with an inside diameter > 300 mm.
The operator receives all necessary information for the precise navigation
of the machine along the vertical axis.
