Hanging basket construction method for suspension pouring section of single cable plane cable-stayed bridge

The invention discloses a hanging basket construction method for a suspension pouring section of a single cable plane cable-stayed bridge. The method includes the following steps of A, hanging basket traveling, B, installation of reinforcing steel bars, a pre-stress system and cable pipes, C, pouring of concrete and D, tensioning, mud jacking and installation of stay cables, wherein the hanging basket traveling includes the steps that that a cantilever is separated from a movement device, an integral structure composed of the cantilever, a suspension arm and a rear cross beam is declined and supported on a flange plate, rear anchor rods are removed, jacks are lifted to enable main trusses to be separated from a sliding boat in a jacking mode, tracks are dragged to move forward, and an insurance distribution beam is installed; the integral structure and the main trusses move forward synchronously; after the integral structure and the main trusses move in place, a horizontal-connection pattern frame and the rear anchor rods are installed, the jacks are lifted to jack a bottom basket until a bottom die of the rear cross beam makes contact with the beam bottom, a front cross beam is jacked to the scale height of a vertical die, and a front lifting rod and a rear lifting rod are fastened. The construction hanging basket for the suspension pouring section of the single cable plane cable-stayed bridge has the advantages of being light in structure, reasonable in stress, large in bearing capacity and high in strength and stiffness and improving construction efficiency, and can be widely applied to the technical field of single cable plane cable-stayed bridge construction.
