The utility model discloses a steel plate prefabricated ultra-high performance concrete hollow pipe internal post-pouring connection structure which comprises a steel plate, and a cross-shaped mechanism is fixed to the steel plate. The structure further comprises a prefabricated UHPC hollow pipe. The bottom connecting area of the prefabricated UHPC hollow pipe is arranged on the cross-shaped mechanism in a sleeving mode. An anti-shearing structure is pre-buried in a bottom connecting area of the prefabricated UHPC hollow pipe; post-pouring UHPC is also arranged in the connecting area; the height of the post-cast UHPC covers the height of the shear-resistant structure and the height of the cross-shaped mechanism, load transmission of the cross-shaped mechanism and the shear-resistant structure is achieved through the post-cast UHPC, and finally reliable connection of the prefabricated UHPC hollow pipes on the end steel plates is achieved. The post-poured UHPC does not need an additional pouring template, the i
