Reduced-scale shield segment mold capable of being recycled

The utility model discloses a recyclable reduced-scale shield segment mold, belongs to the technical field of shield segment test molds, and solves the problems that in a shield tunnel explosion shrinkage experiment, a segment manufactured by using an existing reduced-scale segment mold cannot restore a joint structure in a field shield tunnel, and the shield segment cannot be damaged. The experiment reasonability and reliability are influenced; the mold comprises a mold body which is in a circular ring shape, and the mold body comprises a top sealing block mold, a first adjacent block mold, a first standard block mold, a second standard block mold, a third standard block mold and a second adjacent block mold which are the same in structure and are each of an arc-shaped structure. Mold cavities used for repeatedly pouring pipe pieces are formed in the arc-shaped structures; and a plurality of bent bolt channels are formed in the pipe piece which is poured in the mold cavity. In a reduced scale experiment, the
