Abstract
The prefabricated tunnel lining segment has a pair of blind bolt holes at each end. At one end, the holes open into respective recesses, these allowing access to the exposed bolt ends for fitting nuts. An expanding ring or collar is mounted on the inner end of the bolt. The recesses are pref. square in section and taper towards their bases. A groove is cut in the side of the recess on which the nut bears.
