Construction method for starting arch section at junction of open-spandrel rigid frame bridge column and arch
The invention relates to the field of arched girder combined bridges, and discloses a construction method for a starting arch section at the junction of open-spandrel rigid frame bridge columns and arches, which comprises the following steps of: 1, finishing pier construction, and reserving a framework connecting piece at the arch foot position of a lower chord arch on the side surface of a pier; secondly, a stiff framework is installed at the arch foot position of the lower chord arch, the lower end of the stiff framework is connected with a framework connecting piece, the length of the stiff framework is larger than the sum of the length of the lower chord arch 1 # section and the length of the lower chord arch 2 # section, a temporary buckling cable is installed at the upper end of the stiff framework, the upper end of the lower buckling cable is connected with a pier column, a lower chord arch 0 # section is poured, and the framework connecting piece is buried in the lower chord arch 0 # section; pouring the lower chord arch 1 # section by taking the bottom basket system as a support, and taking the stiff skeleton as an internal support of the lower chord arch 1 # section; and thirdly, the lower end of the lower buckle cable is taken down, a second lower chord arch section is poured with the bottom basket system as a support, and the lower end of the lower buckle cable and the second lower chord arch section are connected. Therefore, the lower chord arch 1 # section can be quickly and efficiently supported.
本发明涉及拱梁组合桥梁领域，公开了空腹式刚构桥柱拱交汇处起步拱段施工方法，包括以下步骤：步骤一、完成桥墩施工，桥墩侧面的下弦拱拱脚位置预留骨架连接件；步骤二、在下弦拱拱脚位置安装劲性骨架，使劲性骨架下端和骨架连接件连接，劲性骨架的长度大于下弦拱1#段以及下弦拱2#段长度之和，在劲性骨架上端安装临时扣索，下扣索上端和墩柱连接，浇筑下弦拱0#段，骨架连接件埋在下弦拱0#段内，以底篮系统为支撑浇筑下弦拱1#段，使劲性骨架作为下弦拱1#段的内部支撑；步骤三、取下下扣索下端，以底篮系统为支撑浇筑下弦拱2#段，将下扣索下端和下弦拱2#段连接。以快速高效地支撑下弦拱1#段。
