Abstract:
EN: Problem statement. Pipeline repair implies that the pipeline must be opened along the entire perimeter of the pip
The complexity of this operation is caused by the limited access to the soil under the pipeline and by the high probability of the pj
damage. The most common equipment for the soil removal from under the pipeline is self-propelled digging-up machines. Existif
constructions of the digging-up machines are imperfect, incapable of excavating the waterlogged soil, ooze and fissured ro
(limestone, sandstone); not able to work with radial sections of the pipeline, also the mechanism of their movement along
pipelines have flaws. Objective. Design and justification of the technical proposal for creation of the digging-up machine that
capable of efficient soil excavation from under the pipeline in the continuous removal mode of the soils with varie
physicochemical characteristics and by doing so ensuring the appropriate motive force without changes of the machine mass!
perform the working process. Conclusion. Technical proposal has been created and the rotary digging-up machine which fulf
modern technological requirements for pipeline repair works has been created; industrial manufacturing of these machines has be
set up.
