Construction operation platform for prefabricated T-beam cast-in-place diaphragm plate of overpass business line

The invention provides an overpass business line prefabricated T beam cast-in-place diaphragm plate construction operation platform which comprises a bottom plate frame and two vertical protection cages fixed to the bottom plate frame, the vertical protection cages are symmetrically arranged, and the distance between the two vertical protection cages is larger than the thickness of a diaphragm plate to be constructed; and the lifting rings are fixed on the bottom plate frame and are symmetrically distributed on the two sides of the bottom plate frame. According to on-site construction experience, the device can effectively prevent splashing welding slag during transverse partition plate steel bar welding, and the bottom plate can effectively prevent slurry from leaking to an existing line below during concrete construction; the space of the platform is abundant, personnel can conveniently construct in the platform, the peripheral steel wire meshes are closed, and the protection effect is good; and by adopting
