FIELD: building, particularly devices for trenchless pipeline laying, which may be used for concealed passage forming during pipeline, communication and electric cable laying.
SUBSTANCE: device comprises leader connected to tubular shaft having discharge orifices directed transversally to axis thereof, mechanism which applies action to ground in leading well, reamer having body secured to front end of pipeline to be laid, wherein the front end is defined in perforation direction. Leader and reamer are provided with single screw blades. The mechanism, which applies action to ground is of gas-dynamical type and is installed on tubular shaft end in reamer. The tubular shaft is fixedly connected to reamer. The pipeline is provided with rotary mechanism.
EFFECT: increased operational efficiency.
