description The invention belongs to the technical field of refining construction of a prestress reinforced concrete prefabricated box beam and discloses a structure for preventing mold expansion and slurry leakage at an end of a prestress prefabricated box beam and a construction method of the structure. The structure is mainly characterized in that high-density foamed sponge is clung to a side ridge of a box beam end mold plate corresponding to a box beam side mold, and the high-density foamed sponge is compressed by the side ridge of the box beam end mold plate and the box beam side mold for a certainratio. The construction method mainly comprises the following steps: a, confirming the position of the box beam end mold plate at the box beam side mold; b, clinging the cut high-density foamed spongeto the side ridge of the box beam end mold plate; c, mounting the box beam end mold plate in an appointed position of the box beam side mold, and fastening and compressing the high-density foamed sponge for a certain ratio; d
