Abstract: The article presents a design solution for a high-precision screw-shaped tunnel lining, which is used in the geowinchester technology of the formation of a cavity in an underground space. Justification of the feasibility of a design solution is due to the presented analysis of existing options for high-precision segmental lining. The comparison of the presented options is carried out according to the main technological parameters of the installation of the tubing support. The analysis of the tubing lining version developed for the geowinchester technology is carried out, the main advantages and disadvantages are highlighted, and the main recommendations for use are given. The developed block structure is possible for use on straight sections of the tunnel route. The known technical solutions for turning the tunnel route used for rectangular lining blocks are not suitable for the screw-type lining. The main directions of further scientific and experimental design work on the development of options for tunnel lining are outlined.
