METHOD AND DEVICE FOR TRENCHLESS PIPE DRIVING Russian patent published in 2010 - IPC E02F5/18 E21B7/00 F16L1/28 

FIELD: mining.

SUBSTANCE: trenchless pipe driving method includes stages whereat within a single stage operations are performed for creation of a well along the given drilling line and driving a pipeline, pre-assembled to form a whole. The required contact forces for drilling and driving are transmitted to the drilling device via the pipeline; the front end of the pipeline is connected to the controlled drilling device, preferably - connected to the pipeline via a connective module. From the outside one applies a force to the pipeline by way of friction, preferably - coupling the pipes with the help of a pusher device, pushing the pipeline from the initial point to the set point, removing the slurry generated during drilling and transporting it from the well hydraulically. The circular space formed between the pipeline and the well wall during drilling is continuously filled with liquid.

EFFECT: performance of trenchless driving of pipes under pressure, especially - in situations when one needs to fulfil certain environmental and economic conditions.
