Ultrahigh-toughness concrete simply-supported-to-continuous-beam bridge structure and manufacturing method thereof

The invention discloses an ultrahigh-toughness concrete simply-supported-to-continuous-beam bridge structure and a manufacturing method thereof. The ultrahigh-toughness concrete simply-supported-to-continuous-beam bridge structure comprises a permanent support installed on a pier, a wet joint structure and a disassembly-free formwork. The disassembly-free template is fixedly mounted on the permanent support, and the wet joint structure is arranged above the disassembly-free template; the dismounting-free template is a grouting groove formed by combining a bottom film and two side films; the outline of the grouting groove is U-shaped; a plurality of studs are uniformly distributed on the groove wall of the grouting groove; the wet joint structure comprises a cast-in-place section and a prefabricated section. The pre-supported simply supported beams of the prefabricated sections are connected through the cast-in-place sections; high-strength micro-expansion concrete is poured on the lower layer of the cast-in-p
