Restoration technologies analysis of underground pipelines and ways to solve possible complications

Abstract

There are works that cannot be performed by traditional machines due to their high energy consumption and low functionality in construction and related sectors of the national economy. These include the laying of underground communications, reclamation and military engineering earthworks, extraction of minerals and building materials, etc.
 The laying process of trench lines for local pipelines, the specifics of which are mainly determined by the trench parameters, is of particular interest. At the same time, laying works of underground communications are performed in a short time and in a limited space as a rule. The main types of work performed are combined with quite complex physical and mechanical processes. This requires the use of special machines that differ from ordinary ones both in the operation principle and in construction terms. High-speed working elements are used in most of these machines, the operation principle of which is based on the dynamic soil destruction theory.
 Earthworks technology with the use of slot-milling work equipment has a sufficient ratio of the «cost – time» criterion. At this time, the need to ensure the dynamism of the work process by means of the high-speed cutter reduces the resistance to the movement of the working element. The need for laying pipes of different diameters can be ensured by replacing the diameter of the milling cutter.
