Description
本发明涉及一种桥梁上部结构施工使用的土木施工法,特别是指一种桥梁上部结构施工使用的支撑升降式施工***及其施工方法。
如图1所示,习知的桥梁上部结构土木施工法是于桥梁上部结构下方桥下空间布满支撑架,支撑架需由地面依序向上于高处组装,在拆卸、组装支撑架及模板设备的每一阶段,均需依赖移动式吊车配合拆组装,施工人员需位于高处拆组装作业,拆除时亦同。
如图2所示,一种习知的桥梁上部结构土木施工法,该施工法为预先于桥梁墩柱或帽梁设置托架,再使用移动式吊车或上车设备将主梁工作车上车完成,拆除亦同。推进时必须先于下一墩柱或帽梁设置安装托架,安装时须依靠移动式吊车配合组装,施工人员需位于高处拆组装作业,拆除时亦同。
综上所述,习知两代表性桥梁上部结构土木施工法技术,分别具有下列缺点:
首先,必须使用大量的支撑架,无桥下空间可供施工利用,工程进行时桥梁下方的道路需封闭施工。
其次,支撑架及模板组装时,施工人员需暴露于高空作业,每一阶段皆需移动式吊车配合施工,拆除时亦同。
再者,每一桥墩柱安装托架时,施工人员需暴露于高空作业,需移动式吊车配合施工,拆除时亦同。
另外,上述两习知桥梁上部结构土木施工***皆需另行搭设供施工人员上下的设备。
