Example Embodiment
[0027] refer to Figure 1 to Figure 7 , the UHPC small box girder structure of the present invention includes a plurality of adjacent box girder bodies 10, the box girder body 10 is prefabricated by ultra-high performance concrete, and the box girder body 10 can also be made of ultra-high performance concrete (UHPC, Ultra-High Performance Concrete) and similar materials, such as high-performance cement-based composite materials such as CRC, DSP, FRHPC, HPFRCC, RPC, STC, UHPFRC, etc. The thickness of the top plate 11, the bottom plate 12 and the web plate 13 varies along the longitudinal direction, that is, the thickness of the top plate 11, the bottom plate 12 and the web plate 13 is relatively large at the end of the box girder body 10, and the thickness of other parts is relatively thick. Small. The box girder body is a thin-walled box girder made of UHPC (Ultra High Performance Concrete) material. Compared with traditional box girder, it saves more material, and the beam w...
