THE FUTURE IS NOW
GRUNDOBORE - 200S
The horizontal auger boring method is a reliable static process for installing sewer house connections as well as product and steel protection pipes under streets and railways tracks. Installation can be either steered or non-steered. In the steered version, the high levels of on-target precision required in sewer construction, for instance are achieved.
The compact GRUNDOBORE 200S is powered by an external hydraulic station with hydraulic drive energy and is particularly suitable for installing sewer house connections and product and protection pipes up to DA 280.
Since the GRUNDOBORE 200S support frame and auger boring unit can be installed separately, launching is possible from a 1 m-manhole or exceptional small work pit.
With quick-locking rods – simple rod connection, no screwing together at the rotary drive.
CORE BIT GUIDE
Precise spot drilling of the manhole wall.
Vertical adjustment of the drilling direction by +/- 11 % is possible after installing the machine.
01. Long stroke for extremely short construction lengths – effective rod length of 450 mm
02. Compact powerful rotary drive – installation of large pipe diameters in the most limited of spaces
03. Galvanised grid – safe base stand operator to stand on
04. Thrust locking via foot pedal – for easy of operation
05. Mechanical, close-fitting rod clamp – safe rod release, minimum wear and tear
06. Semi-circular support plates – secure bracing in a 1 m-manhole

MANHOLE OR PIT LAUNCHING
For launch from a manhole with a fracture opening of only Ø 62.5 cm, the rig can be disassembled into its single components (bore drive with pressing cylinders/ pressing frames).
Support launch frame for pit launch.
Installation of drinking water lines through rock using auger boring in Neuhausen on Eck
The plateaus of the Swabian Alb mountain range are characterised by rocky ground. Places such as Neuhausen ob Eck (770 m above sea level), on the plateau of the Heuberg region, located on the southwest Swabian Alb, already have rocks not very deep below the earth's surface, which makes pipeline construction more difficult. For the drinking water supply to the new industrial estate in the east of the town it was necessary to cross a former main road (B 311), which as a district road (K 5945) is now a very important access road. Because this access road cannot be damaged, the new drinking water main line could only be installed trenchless. It became apparent that the auger boring method also functions reliably in rocky ground.
