Reinforced concrete superposed beam and construction method thereof
The invention relates to a reinforced concrete superposed beam and a construction method thereof. Each of a first pier side span, a first pier middle span, a second pier side span and a second pier middle span of the reinforced concrete superposed beam comprises a plurality of sections. The construction method comprises the steps that the middle box body is installed firstly, and then the inner side box body and the outer side box body are installed; for eleventh blocks, side span eleventh blocks are installed and concrete is poured firstly, and then middle span eleventh blocks, closure section outer side box bodies, middle box bodies and transverse connecting pieces of the middle span eleventh blocks are installed; dynamically adjusting the cantilever of the box body of the reinforced concrete superposed beam: adjusting by using a hydraulic adjusting device on the basis of monitoring, and adjusting the elevation at the same time; and correcting and compensating the monitoring data of the steel-concrete superposed beam cantilever. According to the method, firstly, zero block sections are installed and positioned, then side-span first blocks and middle-span first blocks are installed and positioned, and the installed whole serves as the reference of follow-up splicing; in the splicing process, the elevation, the mileage and the axis are adjusted in time, so that the engineering requirements are met.
本发明是一种钢混叠合梁及其施工方法，所述钢混叠合梁的一号桥墩边跨、一号桥墩中跨、二号桥墩边跨和二号桥墩中跨均包括多个节段。施工方法包括：先中间箱体、后内侧外侧箱体的安装方式；对于十一号块，先完成边跨十一号块安装及浇筑混凝土，再完成中跨十一号块、合龙段外侧箱体、中间箱体及其横向连接件的安装；对钢混叠合梁箱体悬臂进行动态调整：在监控监测的基础上使用液压调整装置进行调整，同时进行高程调整；对钢混叠合梁悬臂进行监测数据的校正补偿。本发明首先对零号块节段进行安装定位，然后对边跨一号块、中跨一号块进行安装定位，安装后的整体作为后续拼装的基准；在拼装过程中，对高程、里程、轴线进行及时调整，使之满足工程需要。
