Shield segment assembling, positioning and split measuring device

The utility model relates to a shield segment assembling, positioning and split measuring device, which belongs to the technical field of shield/heading machine high-end equipment manufacturing and tunnel construction, and comprises a to-be-assembled segment measuring assembly and an assembled segment measuring assembly. A complete set of split positioning and measuring devices installed on assembled segments and segments to be assembled are utilized, the relative position relation of the segment contact surfaces which cannot be visually observed by naked eyes in the segment assembling process is converted into the form which can be visually observed by naked eyes, and a multi-position scale system on the split positioning and measuring devices can dynamically and quantitatively measure key geometric variables in real time. And segment posture observation and fine regulation and control in shield tunnel lining segment splicing operation are facilitated, and the standard operation level and positioning precisi
