In mechanical tunnel formwork systems, this operation is performed using manual or oil\u2011operated screw jacks. Hydraulic systems are typically employed in large cross\u2011sections due to the considerable weight of the formwork segments. In contrast, the use of hydraulic mechanisms in small\u2011scale tunnel formwork is technically challenging and may cause spatial constraints within the internal area of the tunnel formwork.<\/p>\n<p dir=\"ltr\" style=\"text-align: justify\">The lining of a conduit is usually executed in two stages.
