GRUNDORAM pneumatically driven pipe ramming machines are used for the dynamic installation of steel pipes underneath roads, waterways, railway tracks, parks, etc. over lengths of up to 80 m. The TT ramming technology provides thrust forces up to 40.000 Nm, enabling the economic installation of open end steel pipes up to 4000 mm diameter in soil classes 1 - 5 (in part even class 6 - easily soluble rock) without the need for 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 underpasses, small outlets, pipe roofs for tunnel structures, for supporting HDD bores (HDD Assist) with vertical applications being used for foundations, sheet piling or well drilling.
The APOLLO machine is the latest and largest addition to TRACTO-TECHNIK'S range of world renowned pipe ramming hammers, capable of installing diameter up to 4 metres.
A presentation paper will be given at Trenchless Middle East entitled:
Pipe Ramming: Applications and HDD Rescue
This paper reviews the pipe ramming process for installing open ended steel pipes under roads, rivers and rail crossings. Pipes can be installed up to 4m in diameter or over distances of up to 100m. It offers case history examples of projects and different installation methods. A specific focus will be on HDD rescue, including product pipe assistance and drill rod retrieval.
