The invention discloses a restrained recycled concrete structure and a preparation method, and the restrained recycled concrete structure comprises a restraining cylinder which is provided with a restraining cavity defined by the inner wall; the constraint structural member is arranged on the inner wall; the concrete structure body is formed in the constraint cavity in a casting mode, an electro-osmosis drainage device used for draining water is further arranged in the concrete structure body, and spiral-pipe-shaped steel fibers are distributed in the concrete structure body. The comprehensive performance of the recycled concrete can be remarkably improved by adopting performance improvement measures such as doping of spiral tubular steel fibers, electroosmosis intelligent dewatering, tectonic stress constraint and MgO-dry ice water stability treatment in preparation of the recycled concrete, and the recycled concrete can be used as a building material of important and key stress components in a structure. 本申
