The invention discloses hoisting equipment and a construction method which are suitable for synchronously hoisting prefabricated cantilevers on the two sides of a composite-section segmental beam. The hoisting equipment mainly comprises a gantry system, an anchoring system, a hoisting system and a walking system. The gantry system is fixed to a core longitudinal beam through the anchoring system, the prefabricated cantilevers are hoisted to the two sides of the core longitudinal beam through the hoisting system, after the installation of a pair of cantilevers is completed, anchoring between the hoisting equipment and the core longitudinal beam is relieved, and the hoisting equipment is moved forwards through the bridge deck walking system for hoisting of the next segment. The hoisting equipment can ensure sufficient on-beam beam transportation space, so that the hoisting equipment does not influence subsequent cross-core-longitudinal-beam transportation and assembly when a site lacks parking conditions for a large crane ship or a hoisting crane, the efficiency is improved, and the construction period is shortened.
Description
Technical field: [0001] The invention belongs to the technical field of bridge construction, and in particular relates to a double-sided synchronous hoisting device and a construction method suitable for the post-installation cantilever of a segmental girder bridge with a composite section. Background technique: [0002] In view of the characteristics of the "prefabricated core longitudinal girder" assembled first and the "prefabricated cantilever" assembled later, it is necessary to propose a bridge horizontal segmental prefabricated assembly method with excellent mechanical performance, simple and reasonable structure, and fast and convenient construction, as well as a method suitable for this assembly. The walking hoisting equipment of the method. [0003] At present, the longitudinal splicing technology of prefabricated segmental beams is relatively mature, and most of the hoisting equipment commonly used in engineering is also used for hoisting of longitudinal bridge se...
