Abstract
The article presents the option of improving the working equipment of the tunnel-boring complex for laying underground utilities, including trunk pipelines. The method of trenchless laying of underground utilities, consisting in a combination of methods of horizontal directional drilling and micro-channeling, is proposed. The proposed technology does not require the construction of a preliminary mine and a site for the installation of a drilling machine and allows one to combine in one working step the drilling of a well, the laying of a pipeline, welding and insulation works. Presents calculations aimed at determining the forces of movement of the shield, the definition of the power of the shield, as well as the calculation of the strength of the shield. The technique of carrying out technological operations is demonstrated taking into account the use of the proposed technical solution.
