METHOD OF TRENCHLESS PIPING OF PIPELINES IN GROUND Russian patent published in 2018 - IPC E02F5/00 

FIELD: construction.

SUBSTANCE: method includes periodically washing in the soil of the channel with jets of gassing fluid, supplied through the working element, located in the head part of the pipeline, when it is laid along a predetermined trajectory. Piping on a predetermined trajectory is carried out by a percussive mechanism located at the head of a pipeline and rigidly connected to the working body, manufactured in the form of a nozzle, equipped with nozzles located on the outside of the sides of the nozzle and via the control unit with the source of gas-formingfluid. The trajectory of the gasket is changed using nozzles, which ensure the turn of the laid pipeline in the given direction of the gasket.

EFFECT: increasing the efficiency of pipeline in the ground by changing the trajectory of the pipeline feeds jets of gas-forming fluid in the specified direction.
