Self-anchored hybrid beam cable-stayed suspension cooperative system bridge

The utility model provides a self-anchored hybrid beam cable-stayed suspension cooperative system bridge, belonging to the field of building engineering technology, and particularly relates to a design of a large-span bridge in the bridge engineering. The self-anchored hybrid beam cable-stayed suspension cooperative system bridge is characterized in that: after a cable tower and side hole piers are manufactured, a cantilever is assembled to a concrete main beam of the cable-stayed bridge, after the cantilever is assembled to side holes, main cables are suspended, two ends of each main cable are respectively anchored on an anchor block at the outer end of a concrete beam, the anchor block is pulled to a temporary anchoring structure via a temporary anchor cable; a suspension rod is suspended, and each section of steel main beam in the span is hoisted via a cable crane; after folding, temporary anchor cables are dismounted in batches, the main cables are completely anchored at the two ends of the concrete main beam, completing system conversion from temporary ground anchoring to self anchoring, completing bridge floor paving and rail construction, performing cable tension adjustment of full bridge, and forming bridge. The effects and benefits of the self-anchored hybrid beam cable-stayed suspension cooperative system bridge are solving problems of design and construction of large-span bridges, reducing height of tower, full playing material performance, reducing construction cost, shortening construction period, and reducing risk in construction process.
