CoJack is a new efficient method for the static calculation of jacking pipes for loads in the direction of the pipe axis. By means of algorithms especially developed by company Stein & Partner, it has for the first time been possible to accurately determine the constantly varying pipe stress during jacking processes. The rough simplifications of the currently used calculation methods are eliminated in order to optimise the safety and economic efficiency …

In this method, jacking pipes are jacked by pressing-in through the subsoil from a starting shaft to a target shaft with the aid of a jacking station as well as intermediate jacking stations.
Jacking in a straight or curved line path is made possible by means of a steerable shield machine positioned at the head of the first pipe. The spoil excavated at the working face is conveyed to the surface through the jacked pipe string. | |

(Image: Attention!) With reference to the variant used to support the workface or to convey the excavated soil the technical components vary in pipe jacking. | (Image: Schematic presentation of a pipe jacking) |

Advantages of trenchless technology compared to the open cut method: - Preventing break-up and replacement of road surface
- Prevention of soil excavation masses
- Minimizing groundwater retention measures
- Little impairment to traffic flow especially in inner urban areas
- Only short-term noise and emission pollution while excavating the starting and target shafts
