GRUNDORAM technology

The air driven piston inside the machine body strikes against the ramming head. The kinetical impact energy which is released that way enables maximum advancing of the pipe string due the optimal force transmission via the cones. As the constant loads affecting the machine require maximum product quality, the one-piece casing (head and casing are made up of one part) is made out of a solid block which is thoroughly galvanised. The piston is subject to an elaborate hardening process, a tight sealing minimises air consumption. The GRUNDORAM stands for durability and reliability.

GRUNDORAM Accessories

 

    

Lifting cushion (pat.)


Enables exact and simple alignment of the ramming machine behind the steel pipe.

Add-on cones


Guarantees a tight-fitting, stable connection between pipe and ramming machine.

Soil removal adaptors / cones (pat.)

Ensure a stable connection between pipe and ramming machine so enabling partial soil removal during ramming process.

Cotter segments 

Enable the production of a butt welding seam, because the pipe is not flared when ramming, so cutting and grinding  at the welding seam is not necessary.

Advantages of the technique:

  • Less disruption and damage to surfaces worth conserving (road surface, water courses, railway embankments etc.) and minimal restoration – giving economic advantages
  • Low social impact because, diversions, half-sided barriers, traffic signal facilities etc. are avoided
  • Acknowlegded pipe installation technique
  • Short setting-up times - short installation times
  • The dynamic impact when ramming can shatter obstacles and easily overcome difficult starting resistance after standstill periods. The aiming accuracy is improved because the dynamic impact penetrates various soil formations within the diameter range and obstacles do not have to be displaced or pushed aside in one piece
  • No jacking abutment, no auger cutter required, which could get jammed
  • The soil core remains in the pipe during ramming, i.e. no rush of water when rivers or areas with a high water table are undercrossed
  • Minimal ground covering, i. e. no large-scale pits
  • Simple operating technique
  • Adaptation to all pipe diameters with special ram cones
  • Wide range of applications
