Method of trenchless piping of pipelines in ground

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.

SUBSTANCE: method of steering control of the working element for hole making in quick grounds and marshy grounds comprises immersing or rising the working element in case of deviation from the trajectory. At that the immersing or rising the working element is carried out by changing its weight. When emersion of the working element its weight is increased by supplying filler in the adjusting chamber of the working element. While immersing the working element as it moves the weight of the working element is decreased by removing a part of the filler from the said chamber of the working element.

EFFECT: immersion or emersion of the working element in the ground.

Before driving said trench, in front of motor road or railway said protective jacket is placed to accommodate rotary screw with detachable cutting element at its end face directed toward the road. Cutting tool diameter equals protective jacket OD. Screw length exceeds that of protective jacket, screw extension being directed from the road. Screw shaft is engaged with rotary drive placed at slide rails provided with semicircular ledge arranged atop said rails and directed toward protective jacket above said screw, its end and jacket ends are jointed together by flanges to be bolted together. Slide rails are to be fixed relative to drive by "П"-like bracket secured at drive frame to thrust against slide rails rear end and to surround them from both sides. Then, screw drive is switched on to displace slide rails with revolving screw and protective jacket toward the road so that said jacket penetrates into soil to get completely buried therein. Then, said cutting element and bolts are removed from screw end. Then said screw is withdrawn from said jacket to fit main pipeline section therein.
