Abstract

Summary.  Raising of problem.  On the basis of the analysis of modern technical condition of pipelines in Ukraine and in other countries  is  concluded  that  there  is  an  unsatisfactory  condition  of  pipeline  routes  in  almost  all  countries.  Reliable  operation  of pipelines is possible only through the replacement of worn-out sections of pipelines with new pipes or due to their major overhaul. The rate of repair work must be dramatically increased to maintain the necessary reliability of pipelines. It was found that low growth excavation works  are the most limiting factor  of  increasing  the rate of repair work that need to  be  raised  a minimum  in 5-7 times. Bringing the rates of excavation works to the rates of repair works on pipelines is possible only through the creation of new  special continuous action diggers.  By using them it  will be possible to lead the  major overhaul of pipelines with the high-speed method without a pipe lifting referring to its initial line of bedding.
