合用凹所の閉塞構造。[Claim for Utility Model Registration] A bolt insertion hole is formed between the joint end surface of the segment body and a bolt connection recess provided near the joint end surface, and the bolt insertion hole extends inward. At the joint part of the concrete segment, a bolt relief hole is formed on the top of the concrete segment, which faces the recess that allows the bolt to be inserted into the bolt insertion hole once the bolt is inserted. The structure is such that the hook is fixed to the bolt escape hole, and the closure lid, which is formed into a polygonal shape in plan view, has elasticity and can be rotated from a free state to change its length. The suspension member is suspended in a contracted state by a suspension member that contracts, and in this state, the closure cover is fitted into a counterbore hole of the same shape as the closure cover formed around the opening of the recess. A structure for closing a recess for bolt connection in a joint portion of a concrete segment, characterized in that the surface thereof is substantially flush with the inner surface of the segment body.
