A steel plate comprises a vertical web plate, an upper flange plate and a lower flange plate, an acute angle is formed between the upper flange plate and the web plate, the lower flange plate is perpendicular to the web plate, shaping plates are arranged at the two ends of the steel plate, and the shaping plates are perpendicular to the steel plate; when every two adjacent steel plates are spliced, the shaping plates at the splicing position are tightly attached and fixed through C-shaped buckles, a plurality of reinforcing plates are fixed to the inner sides of the steel plates at intervals, and inner fixing sleeves are welded to the positions, close to the reinforcing plates, of the inner sides of the web plates and movably fix supporting frames. The supporting frame comprises inner vertical deformed steel bars, diagonal bracing deformed steel bars, horizontal deformed steel bars, outer fixing threaded sleeves, outer vertical deformed steel bars and hoops. During actual pavement assembly construction, only
