Main beam cable-stayed suspension forming technological method for self-anchorage type suspension bridge
The invention discloses a main beam cable-stayed suspension forming technological method for a self-anchorage type suspension bridge. The main beam cable-stayed suspension forming technological method comprises the steps that (1) a bridge foundation, bearing tables, bridge piers, a bridge tower and side span cast-in-situ sections are constructed in sequence; (2) a main beam and temporary stay cables are installed section by section in sequence in the direction from the part close to the tower to the midspan until all main beam sections are installed; (3) all the main beam sections are combined to form the integral main beam, an anchorage channel and a main cable are installed, the cable is tightened, and cable clips are installed; (4) slings are installed in the direction from the part close to the tower to the midspan in sequence and tensioned, the corresponding temporary stay cables are demounted at the same time, the system transformation to a sling system from a temporary stay cable system is completed in the demounting process of the temporary stay cables, and the suspension cable force of the temporary stay cables is transformed into the cable force of the slings; (5) auxiliary works are completed, the force of the slings is adjusted, the whole main beam is formed, and the bridge can be handed over for traffic operation after the main beam is formed. According to the technological method, temporary bridge piers do not need to be arranged, navigation is not influenced, the construction cost is greatly reduced, and safety is improved as well.
