FIELD: construction; replacement of underground utilities without soil opening.
SUBSTANCE: technical result is achieved by the fact that in the traction body of the claimed invention instead of a double hydraulic jack is used one hydraulic cylinder with a through rod, which makes it possible not to use a bearing plate and crossbar as part of the device, but to place working modules of various purposes inside the hydraulic drive.
EFFECT: technical result is possibility of both laying new underground utilities, and replacement of already arranged in ground communications using one device, as well as reduced weight of device for trenchless replacement of underground pipelines and increased repairability of device due to use of dismountable structure and reduction of specific metal content of article.
