The dynamic ramming technique
        
Grundoram pneumatically driven pipe ramming machines are used for the dynamic installation of steel pipes underneath roads, waterways, railway tracks, parks, etc. over lengths up to 80 m. The TT ramming technology provides thrust forces up to 40.000 Nm, enabling the economic installation of open steel pipe up to 4000 mm diameter in soil classes 1 - 5 (partly even  class 6 - easily soluble rock) without jacking abutments.  
The steel pipe ramming technique is suitable for installing longitudinally or spirally welded pipes, seamless pipes and pipes with insulation protection as product  pipes,  e.g. in pipeline construction, or as casing pipes for supply und drainage pipe bundles.  The pipe rammers are also used horizontally for constructing underpassees, small outlets, pipe roofs for tunnel structures, for supporting HDD bores (HDD Assist). Vertical applications are foundations, sheet piling or well drilling.
