MINIMALLY INVASIVE

With the GRUNDOPIT KS50, gas, water, electricity and FTTH service connections are installed from the main line in the road in the smallest possible, round work pit (keyhole of just Ø 65 cm) or a narrow pit of just 65 cm in width directly into the building or into a small assembly pit in front of the house.

Drilling from the smallest round work pit,Ø 65 cm keyhole
Directional drilling with continuous detection
Simple operation via control panel with colour display
No work pits on private properties, bores directlyinto the basement possible
Minimum excavation work –l ess is simply impossible
Only very small work area required,minor traffic impairment
Eco-friendly and gentle installation method
Minimal drilling fluid requirements
No elaborate asphalting necessaryfor restoring the keyhole
All connection jobs are carried out from the surface
Drilling lengths up to 50 m
Pipe diameter up to 90 mm

QUICKSTARTER

COMPACT, POWERFUL, PROFITABLE

CONTROL PANEL

Fully automatic drilling
Operation from the surface
Ergonomic mode of operation accordingto the latest standards
Directional detectable bore
High safety for the operator
Clearly arranged colour display with icons
Infinitely variable adjustmentof the optimal drilling parameters

ROTARY DRIVE

Rotary drive with hollow shaft – maximum rod length for the smallest installation space
Positive-fitting rod link – soiling-resistant, material-friendly
Torque-dependent thrust regulation – optimal utilisation of the machine output

ROD changE

- Fully automatic rod handling
- Ergonomic, quick, safe

Truck platform (complete system solutions)

- Flexible transport-module

01 Integrated machine controls– fully automatic drilling
02 Fluid-assisted soil displacement method–No 'flushing out of the bore cuttings'
03 Small space between bore axis and bottom edge of machine– direct connection of service pipe to the main line
04 Integrated rod cleaning by means– of high-pressure washing jet
05Minimally invasive drilling – from out of the smallest possible working pit, Ø 650 mm 'Keyhole'
06 Closed round frame design – stably, flexibly directional (machine can rotate freely inside the keyhole)
07 Integrated hydraulic tensioning system – short set-up times, safe installation

Demonstation of the Keyhole method for Gasnetz Hamburg

The gas network of the free and Hanseatic city of Hamburg consists of approx. 7,900 km of pipelines and around 160,000 service connections for almost 230,000 network customers. Within the framework of a week-long demonstration the urban operator Gasnetz Hamburg GmbH convinced itself of the benefits of the minimally invasive procedure for the quick and gentle production of gas service connections from a small circular pit with a maximum diameter of 65 cm.
