Prestressed concrete box girder short line matching segment prefabricating system and construction method

The invention provides a pre-stressed concrete box girder short line matching segment prefabricating system and a construction method, and relates to the technical field of box girder short line matching segment prefabricating, the pre-stressed concrete box girder short line matching segment prefabricating system comprises the following steps: step 1, excavating a bottom die pit slot; 2, a side die fixing base is installed; 3, a bottom die system is installed and adjusted; step 4, installing and adjusting the side mold; step 5, mounting a steel reinforcement framework; 6, the inner mold and the end mold are installed and adjusted; and step 7, circularly prefabricating the segmental beam. The occupying and adjusting mode of a bottom die system is improved, the side die positioning and measuring mode is changed, an inner die and end die system is integrated, the occupied operation space is reduced, and the prefabrication operation precision and efficiency are improved. 本发明提供一种预应力混凝土箱梁短线匹配节段预制体系及施工方法，涉及箱梁短线匹配节段预
