Bridge total external prestress concrete segment spliced light thin-walled box girder
The invention relates to the field of civil engineering bridges, in particular to a bridge total external prestress concrete segment spliced light thin-walled box girder formed by splicing a plurality of prefabricated segments. The bridge total external prestress concrete segment spliced light thin-walled box girder comprises pier top segments, turning segments and external prestress steel penetrating the pier top segments and the turning segments. The bridge total external prestress concrete segment spliced light thin-walled box girder has the beneficial effects that a brand new box girder structural form is created, a vacancy in the prestress technology in China is filled up, and the problems that the theory is vague and the standard is vacant in the domestic external prestress concrete bridge structural design are solved with the concept of a 'multi-span hidden type extradosed cable-stayed bridge'; the external prestress steel is totally arranged outside girder body concrete, corrugated pipes do not need to be embedded, and the grouting construction is not needed; and the concrete pouring quality is high, the splicing and bridge forming speed is high, and the splicing speed of seven days for one span can be achieved for medium and small span bridges.
