Construction method for erecting steel-concrete composite beam by using jacking equipment
The invention discloses a construction method for erecting a steel-concrete composite beam by using jacking equipment, which comprises the following steps of: (1) prefabricating steel beam sections; (2) installing the jacking equipment on a descending bridge girder erection machine; (3) installing the bridge girder erection machine at the position of a first hole bridge pier; (4) hoisting and splicing the steel beam sections; (6) removing jacking equipment; (7) moving the bridge girder erection machine to a next hole of pier, hoisting a steel beam section to be connected with a previous hole of steel beam into a whole, and completing the working condition conversion of'simple support to continuous' of the hole of steel beam; (8) mounting a precast concrete bridge deck at a midspan position and pouring; (9) removing the jacking equipment. And a pier top hogging moment area prefabricated concrete bridge deck is installed and poured. The steel-concrete composite beam has the advantages of traditional support construction and support-free construction of the steel-concrete composite beam, the combined stress performance of the steel-concrete composite beam in the bridge forming stage can be fully exerted, and the steel-concrete composite beam is highly competitive in bridge construction in crossed road crossing and construction period sensitive areas.
本发明公开了一种利用顶升设备架设钢混组合梁的施工方法，包括：①预制钢梁节段②在下行式架桥机上安装顶升设备③将架桥机安装在第一孔桥墩位置④吊装钢梁节段并拼接⑤将钢梁顶升至设定值后锁定，安装预制混凝土桥面板，浇筑湿接缝混凝土⑥撤除顶升设备⑦移动架桥机至下一孔桥墩处，吊装钢梁节段与上一孔钢梁连接为整体，完成该孔钢梁“简支转连续”的工况转换⑧安装跨中位置的预制混凝土桥面板并进行浇筑⑨撤除顶升设备，安装墩顶负弯矩区预制混凝土桥面板并进行浇注。本发明具有传统有支架施工和无支架施工钢混组合梁的优点，能够充分发挥成桥阶段钢混组合梁的组合受力性能，在跨越被交道和工期敏感地区桥梁建设中极具竞争性。
