The invention discloses a large-span cantilever bridge stabilizing structure and a using method, and belongs to the technical field of cantilever bridges, the large-span cantilever bridge stabilizing structure comprises a connecting column fixedly connected to the bottom of the cantilever end of a cantilever bridge, and a protruding part is arranged at the bottom of the connecting column; a cavity is formed in the inserting pin, a through groove is formed in the top face of the inserting pin, the through groove communicates with the cavity, the protruding part is slidably installed in the cavity, and a stabilizing block is fixedly connected to the bottom of the cantilever end of the cantilever bridge adjacent to the cantilever bridge where the connecting column is located. An inserting opening is formed in the side wall of the end, close to the connecting column, of the stabilizing block, a driving device is arranged in the protruding part, the inserting pin is inserted into the inserting opening through the driving device, and a fixing device for fixing the inserting pin is arranged in the stabilizing block. The structure has the effect of enhancing the stability of the cantilever ends of the adjacent cantilever bridges.
Description
technical field [0001] The present application relates to the technical field of cantilever bridges, in particular to a stable structure and usage method of a long-span cantilever bridge. Background technique [0002] A cantilever beam bridge refers to a beam bridge in which one or both ends of a simply supported beam is freely suspended outwards as the main load-bearing member of the superstructure. Cantilever bridges can be divided into single cantilever bridges, double cantilever bridges, porous cantilever bridges, T-shaped cantilever bridges with hanging holes and other forms. The most commonly used cantilever bridges in engineering are single cantilever bridge and double cantilever bridge. Cantilever beam bridges are generally statically indeterminate structures, and the internal force of the structure is not affected by the deformation of the foundation, so the requirements for the foundation are relatively low. [0003] The current construction plan of the cantileve...
